Running in winter studded tires - subtleties and rules - DRIVE2
Buying winter tires in a modern tire store gives car owners a lot of pleasure. Huge selection, prices to suit every budget, tires with studs and extended tread... The current range of automotive products is difficult to list. Many people prefer to buy tires with studs for winter use, be it Nokian or Bridgestone.
Manufacturers promise that the studs will help cope with skids, reduce the braking distance of the car and significantly improve its grip on the road. But Michelin experts say that a procedure such as running in winter studded tires is necessary. It is worth understanding this statement and clarifying the procedure for running in tires.
"Health" of tires after a good run-in
Any tire needs running-in, because new tires have less traction with asphalt than old ones. Therefore, after changing tires, you need to be careful, get used to the braking distance and other changes in the car’s behavior on the road.
Studded tires have one more need for running in - installing the studs in the correct positions. Only after 500-600 kilometers do the studs take their place in the rubber and begin to perform their assigned tasks. The running rules are as follows:
Driving during the first 500 kilometers should be done at speeds of up to 70 kilometers per hour; sudden acceleration and braking can cause the loss of studs; attention must be paid to changes in the vehicle’s grip on the road.
The Yokohama manufacturer prescribes the rules for running-in in the instructions and documents for the supplied tires. Gislaved also did this for some time, but today the driver does not receive any instructions when purchasing this tire. It doesn't matter what brand of tires you use. The rules for running in winter tires are the same for all types.
Caution on the road is the main rule of running in
As mentioned above, the braking distance of a car on new tires can be significantly longer than on old tires. This effect is present for the first few hundred kilometers. So you need to pay special attention to maintaining speed limits and distances. Changing the usual behavior of a car on the road is fraught with unpleasant consequences.
The only manufacturers that do not give any break-in recommendations are Goodyear and Dunlop. These companies claim that their studded tires are able to immediately fulfill all their properties:
improve braking on slippery roads; provide excellent acceleration even on icy asphalt; resist wheel spin when starting to move.
Judging by the reviews of drivers on various forums, these statements are far from the truth. The procedure for producing winter tires with studs is the same at different factories. So all types of tires need running-in.
It is better to buy and install winter tires in advance, because running them on dry asphalt is easier than on icy roads. Experts from the Kumho concern do not recommend changing tires at the height of the winter season. They argue that the driver simply will not have time to adapt to the new behavior of his car, and the risk of getting into an unpleasant traffic situation will increase significantly.
Let's sum it up
Running in winter studded tires has become a necessity, because it will ensure not only proper operation of the tires, but also the driver’s getting used to the new habits of his “iron horse”. If you value safety and confidence on the road, you should think about changing your tires in advance, while the roads in your city are dry and not covered with a layer of ice.
You also need to remember that long-distance road trips on new tires are inadmissible. Speeds above 70 kilometers per hour can destroy new tires, and all the studs you paid a lot of money for will remain on the side of the road.

Running in studded tires
About the rules for running in new winter tires
The spikes are mounted into an already welded tire - they are pressed into holes molded in the rubber. After studding, the tire should rest for a day at room temperature. During this time, the rubber tightly grips each spike and flows into all their nooks and crannies.
However, even a well-functioning stud machine has a tolerance for studs protruding above the tread surface. Therefore, some spikes sit deeper, while others, on the contrary, protrude a little more. The task of the break-in is to help each spike get into its rightful place as it should.
When the car moves, the studs begin to move slightly in the rubber and tend to take the correct position in the molded hole. Naturally, during such a period it is necessary to avoid wheel slipping during acceleration and braking, as well as lateral slips.
The more careful the running, the longer the studs will last.
Ideal conditions are snow-covered roads and speed no higher than 90-100 km/h. In such conditions, over 800-1000 km, the studs settle into place under the influence of internal friction of the rubber. On asphalt and ice, the run-in will be completed faster because the studs interact with the hard surface. It is enough to drive 500-700 km, but it is advisable not to accelerate faster than 80 km/h.
In any conditions, it is better to break the run-in into several trips ranging from 150 to 300 km, with breaks of an hour or two for the rubber to cool so that the studs are fixed in the desired position.
On shorter trips, the tires hardly warm up in the cold, so the total break-in mileage will increase.
Nokian, Pirelli and some other tires (they say even Cordiant already makes them) have a stud break-in indicator.
The only exception is the Continental IceContact 2 studs. These are the only tires of their kind - with studs glued into the rubber during the vulcanization process. This solution makes it possible to limit the running-in period to a hundred or two kilometers, after which they are ready to boast of high grip on ice that is stable throughout the entire operation.
Be careful - thorns!
On ice, the life of the studs is shortened not by full-throttle braking, but by intense slipping during acceleration. Studs usually fly out of the rubber not so much from lateral (relative to the vertical axis of the stud) forces, which on ice are not strong enough to turn the studs out of the tread, but rather under the influence of centrifugal force during prolonged slipping and movement at high speed.
Another situation that is deadly for studs is when, during intense slipping, the tire gnaws through the ice to the asphalt. The studs receive a strong blow, causing them to be twisted out of the rubber.
Therefore, start with tension, smoothly operating the clutch at low engine speeds - the result will be more successful, and the studs will be intact.
On asphalt, even frozen, it is better to avoid slipping altogether, since on such a surface increased lateral forces act on the studs
The studs also get hit when the driver turns the steering wheel in place, maneuvering in a limited space on a hard surface. Very often, after such maneuvers, scratched semicircles or even fallen spikes remain on the asphalt or concrete. Therefore, in such situations, try to turn the steering wheel only when the car is moving.
Take care of the thorns! And they will save you from danger

How to break in studded tires
A huge number of modern car enthusiasts appreciate the benefits of studded tires. "Spike" is simply irreplaceable in harsh winters, on slippery and snowy roads. But in order for studded tires to serve faithfully for more than one season, they need to be properly broken in.
1
Don’t delay purchasing studded tires, make your purchase in advance and refit your car before the onset of frost and ice. Any wheels require preliminary running-in, and studded ones even more so.
On a dry asphalt road, you will have the opportunity to get used to and “feel” the tires, which in the future will give you the opportunity to understand how to properly drive a car on slippery icy areas, and what to do if you skid.
2
Buy studs for all wheels of the car - this will ensure the correct operation of the vehicle. Installing studded tires on only one axle of the car is an extremely risky and unjustified action, because the movement of your car during a skid can become very unpredictable. By the way, this also applies to all-wheel drive vehicles.
3
Installing a “spike” is a case where savings can be fraught with serious consequences.
Entrust the “re-shoeing” of your “iron horse” to the specialists from the service center, who will carry out the installation in accordance with all the rules: they will install the newly purchased tires on a clean rim, replace the old valves with new ones and be sure to balance the wheels. The next balancing awaits you after 400-500 km (to eliminate possible imbalance), when the tire sits tightly on the rim.
4
When rolling in studded tires, try to avoid sudden movements. Pay special attention to the first hundred kilometers of the run, when not only the studs “roll in” to the tires, but also the studded tires “roll in” to the disc.
Unjustified maneuvers, starts with slipping, emergency acceleration, as well as emergency braking of the car, are now completely useless. After all, you didn’t buy new tires just to burn them out.
Remember that the optimal speed for the “break-in” period (which is about 500 km) is no higher than 70-80 km/h.
5
While running in the studs, periodically check the tire pressure (at least two to three times a month). The optimal tire pressure is indicated in the manual (vehicle maintenance and operation manual) or on the information plate located inside the car.
Insufficient pressure can cause loss of studs and rapid tire wear. Agree, it is much more expedient to spend a few minutes a couple of times a month checking the pressure than to buy a new set of tires.
Following simple recommendations will help extend the service life and greatly increase the reliability of studded tires.

Running in new winter studded tires
If you purchased new winter studded tires, then you have probably already been told about the need to break them in. This is a very important point. After the new tires are mounted on the car, they need to be broken in. You will have to refrain from fast travel for a while, but then you will be able to ride in your usual style.
Why do you need to break in studded tires?
Running in studded tires is necessary so that its tread acquires a rough surface. Only in this case will the driver feel confident on the road, even in the most extreme situations.
This process will allow you to feel contact with the road, and the wheels should be balanced with each other and work as a single whole. The stability of the car while driving on the road increases, controllability improves, and the chances of skidding are leveled.
We recommend that after “re-shoeing” you undergo a wheel alignment procedure in order to significantly reduce tire wear.
Break-in process
- Find a dry asphalt track.
- The optimal speed will be about 60-70 mph.
- You will need to travel about 500-700 km.
- Try to drive calmly, without sharp turns, as the new tires need to adapt to the road, and its surface should soon acquire a rough surface.
Important nuances
You cannot drive fast on new tires and do not apply sharp braking, as in this case they will not be effective when braking in the future.
It is no secret that the studs are installed in special grooves with lubricant, which must evaporate before active use.
As long as lubricant is present at the place where the “spike” is attached, it is subject to play and worsens its traction characteristics with the road. The wheels should rub against each other. This process is much like breaking in an engine.
In essence, everything is the same - low speed and only small loads.
So you will have to temporarily forget about your previous driving style and drive at a speed of 60-70 mph for at least the first 200-300 km. If at the very beginning of operation you neglect the speed limit, then you risk losing your own studs, and this will lead to the purchase of new wheels.
Choosing winter tires
In order for the driver to feel confident on the winter road, it is necessary to choose the right tires. Each car has its own wheel and tire parameters. Compliance with the requirements for the characteristics and parameters of rubber is mandatory. Incorrectly selected wheels can cause an accident on the road and other critical moments.

Running in studded tires - is it necessary?
Some drivers are sure that studded tires need to be broken in, although they do not understand why, while others are convinced that no break-in is required. In this article we will talk about how running-in affects the characteristics of studded tires, and you can decide for yourself whether your car needs it or not.
How studded tires are made
To understand the issue of running in, you need to understand how studded tires are produced. Any tire is based on a frame made of metal or polymer cord, as well as layers of special fabric that reinforce the structure.
The cord and fabric are located in the middle and inner part of the tire, so they are the same for both studded and non-studded tires for any season.
After creating the cord and laying the first fabric layer, the inside of the tire is filled using a complex composition consisting of artificial rubber, carbon black and other components.
Then another layer of reinforcing fabric is laid and the outer part is filled in with a non-studded tire. And in the studded one, the studs are first glued, coated with a special lubricant that prevents sticking to the rubber, and only after that the outer layer with the tread is poured.
What happens during break-in
During break-in, two processes occur:
- under load, the remaining glue and lubricant are squeezed out of the stud chamber, which reduce traction;
- the driver gets used to the behavior of the car shod with new tires.
Squeezing lubricant and glue out of the stud chamber is an inevitable process, because at the point of contact with the ground the tire experiences a pressure of 200–400 kilograms, and even more when driving over bumps.
The release of residual glue and lubricant will end only after they are completely squeezed out of the chamber.
Therefore, running-in removes these substances with minimal risk, because during running-in the driver avoids sudden acceleration and braking, as well as excessive speed, due to which the lubricant and glue have almost no effect on the tire’s adhesion to the road.
During the break-in, the driver gets used to the behavior of the car with new tires, because each tire has a certain grip on a clean road and on an ice or snow covered road, so the driver must learn to feel the car in a new way.
Otherwise, there is a high probability that in a dangerous situation he will not be able to correctly predict the behavior of the car, which is why he will make a mistake. In most cases, such an error leads to a collision with an obstacle and costly repairs.
From the experience of many drivers, it is known that neglecting break-in leads to the loss of up to half of the studs already in the first season.
Indeed, during a correctly performed running-in, the studs take their place, some sinking a little deeper, others rising.
If the studs, after the release of the lubricant, do not occupy the optimal place, then there is a high probability that the very first sharp braking or rapid acceleration will lead to the stud flying out of the tire.
What is break-in
This term refers to careful driving at low speeds (60–100 km/h). At its core, running in studded and non-studded tires differs from running in an engine only in the distance required to complete the process. In most cases, it is enough to drive 500–700 kilometers for break-in, after which the tires are ready for further use without any restrictions.
Conclusion
Whether to break in studded tires or not is up to each driver to decide for himself. Understanding the processes that occur with a tire during break-in, as well as the changes in tire characteristics during the break-in process, helps you make the right choice. After all, even if normal running-in is impossible, the driver, understanding the processes occurring with the tires, will be able to react correctly in dangerous situations.

Running in new summer or winter tires after purchase
For any car or motorcycle, buying new tires is almost the same as buying new shoes.
We strive to buy not only something practical and beautiful, we want our feet to feel comfortable in new shoes and not experience any stress associated with tightness, friction and similar undesirable phenomena of new things.
When buying new tires for your car, keep in mind that, like us, it also needs time to “break in” the new thing, so to speak, and feel comfortable and comfortable in it.
Why do you need to break in new tires?
The sight of new tires does not leave indifferent even those who are not too interested in cars. It attracts attention with its brilliance and gloss, but it is really smudged after it was released from production.
But what about tires that were released some time ago, but never went on sale, and are stored in warehouses or bases for years? In order for rubber to be stored better and longer, it is treated with a special agent that penetrates several millimeters into the tire, providing a reliable protective layer. During running-in, this top layer is erased and the rubber acquires all its effective properties that the manufacturer put into it.
How long to break in
During the process of running in new tires, the driver himself gradually gets used to safe driving. After a car has been “changed” to new ones, it significantly changes its behavior and handling characteristics.
Therefore, during the break-in process, which involves leisurely and limited speed driving for the first 100-500 km , the driver gradually gets used to and gets used to a certain driving style with new tires.
Features of running in summer tires
When trying out new tires, you should never resort to extreme driving methods or try to impress someone with stunts and turns.
Such techniques can significantly worsen the condition of new, unrun-in tires, and are also quite unsafe. After an overnight rest, new tires must be given time to warm up.
In other words, experts advise driving a certain distance at a speed of no more than 60 km/h.
Summer tires break in faster than winter tires. As a rule, it is enough for her to travel 500 km, at an average speed of about 80 km/h. For winter tires, at this break-in speed you will have to travel about 700 km.
How to break in winter studded tires?
This type of rubber differs from regular rubber in its more complex characteristics and properties. Therefore, the running-in process will be more complicated.
It is recommended to break in studded tires before frost sets in or the roads become icy. The running speed of this tire will be less than that of regular tires, about 60 km/h, over a period of 500 km.
During this time and distance, all the lubricant applied to the tire by the manufacturer is erased, and the studs firmly take their place.
You should not ignore these simple but practical rules, developed by experience and over the years. After all, both the condition of your car and your own well-being depend on their compliance.
Running in motorcycle tires
If for cars running-in is more of a recommendation than a guide to action, then in motorcycles this action is vital.
The fact is that during the production process of tires, in order to separate them from the matrix, a slippery layer is applied to them. It is this that needs to be erased in the first 100-300 km with a smooth run-in.
Otherwise, the likelihood of falling during turns increases greatly.

Instructions: How to properly break in new car tires
Car tires are purchased for more than one season, both winter and summer. With proper use, the tread pattern on them can remain for many years, providing the necessary traction of the car with the road.
The key factor that directly affects the durability of car tires is its proper running-in. There is an opinion that only winter tires need running-in, but this is not true.
Tires with studs require more attention when preparing them for use, but summer tires must also be properly broken in before full use.
Do I need to break in new tires?
To understand why experts recommend running in tires before full use, you need to understand the tire production process.
Automotive rubber is cast from a special rubber mixture into molds of the required diameter with the required tread pattern.
The inside of the mold is lubricated with special oil, which is necessary in order to remove the rubber after hardening without causing damage to it. Oil particles remain on the tread pattern, and in this form the tires go on sale.
Despite statements from tire manufacturers who claim that the break-in procedure is not mandatory, experts recommend performing it. Running in car tires allows you to remove remaining oil particles, the presence of which can directly affect the behavior of the car:
- When braking sharply, fresh tires run the risk of not braking and slipping, which can lead to an accident;
- When entering a turn at high speed, a car on new tires may skid or roll over.
First of all, tire running-in is required precisely to increase the safety of driving a car, and not to increase the service life of the rubber. But if we are talking about studded tires, then their proper running-in will extend their service life.
How to break in new tires
The running-in of car tires takes place over a period of 400-500 kilometers. There are 3 rules for how to properly prepare new tires:
- It is necessary to avoid sudden acceleration of the vehicle, which can lead to tire slippage;
- Turns should be taken at low speeds, and the steering wheel should rotate smoothly without jerking;
- It is advisable not to use new tires in the rain to avoid unnecessary skidding.
The above rules are relevant for both summer and winter tires, regardless of the presence or absence of studs on them. After running in the tires for 400-500 kilometers, it is recommended to continue using the car and tires in a gentle mode for another 1000 kilometers, avoiding sharp turns and lane changes.
When producing studded tires, the stud installation sites are lubricated with a special product. Their initial running allows you to remove the remnants of this substance and tightly fix the tenons in the grooves.
When preparing for long-term use of studded tires, the following recommendations must be added to the break-in rules given above for the first 500 kilometers:
- Running in winter tires should begin before snow falls or heavy precipitation begins. On wet asphalt, the driver will not feel the car, and there is a high risk that it will skid or the tires will slip when braking;
- Studded tires must be installed on all 4 wheels;
- It is recommended to run in studded tires at a speed no higher than 70 kilometers per hour, so it is better to avoid long trips on country roads on new tires;
- It is necessary to carefully monitor the pressure in studded tires, both at the break-in stage and after, during standard use of the rubber. Spikes actively fall out if the tires have insufficient pressure.
When purchasing a tire, you need to check with the seller whether there are any special recommendations for running them in from the manufacturer. If the seller does not provide such information, you can try to find it on the website of the company that produces the tires.
The first few hundred kilometers on new tires are stressful not only for the tires, but also for the suspension. When performing a break-in, the driver also takes care of the durability of the car’s expensive components, which are not used to working when the car has poor road stability.

The importance of running in winter tires - truth or myth
Among motorists, the question is often asked: “Do I need to break in the tires after installation?” Let's look point by point to see if this is really important or running in studded tires is just another automotive myth:
So, let's start with the simplest and most unambiguous - with the regulatory component: there are “ Rules for the operation of automobile tires AE 001-04 (download in PDF format), which are the main document defining the procedure for servicing and operating automobile tires on the territory of the Russian Federation.
By the way, the installation of “Ш” is also required by traffic rules, and starting from April 4, 2017, the absence of this sign is included in the list of faults for which the operation of vehicles is prohibited, and a fine of 500 rubles is imposed for its absence.
With the legal component, everything is now clear - running in studded tires is necessary and even mandatory, there are recommended distances and speeds.
Let's look at the issue from the point of view of tire manufacturers, because not every car owner knows the nuances of the work of tire companies.
When producing tires, a special lubricant is used to prevent the cast tire from sticking to the mold. Removing such lubricant that has penetrated into the upper surface layers is one of the tasks of running in tires before active use.
That is why all tire manufacturers, without exception, pay attention to the need to break in both winter and summer tires, but this information, unfortunately, is not always conveyed to retailers and customers themselves.
Now let's look at the issue of the need to run in tires with anti-skid studs from the point of view of studding.
When studding tires, the machine automatically supplies a moisturizing mixture (water with a special shampoo) into each hole, where an anti-skid stud is then installed. This mixture acts as a lubricant to facilitate studding and protects against the formation of micro-tears. The use of lubricant is mandatory, because
even the smallest passenger stud has a flange diameter of 8mm - this is the size of the bottom “cap” that goes into the rubber like an anchor, and the diameter of the finished hole in passenger tires rarely exceeds 3mm.
The hole is stretched by the jaws of the gun and the tenon is pressed in under pressure, then the jaws release the edge and the rubber “collapses”.
This is all achieved by driving a car on new studded tires for some distance at low speeds and at a calm pace, preferably at positive air temperatures, when the tires are a little “warmer” than in winter. During preliminary running-in, the stud in the hole sways slightly (by tenths of a mm), occupying a comfortable place for itself, just like a driver in the seat of a new car is looking for the optimal position.
From the point of view of studs, running in the rubber is especially important for the durability of the studs , because
If the very first trips involve high speeds, sharp accelerations, braking and lateral drift, there is a high probability that the stud in the heated rubber will take a position convenient for reducing resistance. Those.
will simply lie on its side, bringing one of the edges of the flange closer to the surface (instead of sitting like an anchor - strictly vertically) and lock in this position, then subsequent extreme maneuvers will tear it out of the already weakened position.
4. The nuances of tire storage
Before long-term storage, it is recommended to treat tires with a preservative that prevents the evaporation of oils and carbon black from the rubber so that it loses its properties less actively.
By the way, evaporation is also associated with deterioration or change in the behavior of tires on the road after seasonal storage (when the tire has been in use for several years).
And this is also related to the ban on storing tires in apartments, on balconies and generally near homes: the fumes are harmful and a fire hazard.
If during storage, along with the evaporation of substances from the composition, the rubber has lost the elasticity, softness and resilience specified by the manufacturer, or, on the contrary, has acquired excessive rolliness and cottoniness, then during a leisurely running-in you will feel it, but in a difficult situation, will you have time?
Accordingly, rolling is also indicated to remove these preservatives from the surface.
5. Features of tire retail sales
In addition, many retail stores and private sellers of used tires that sell winter studded tires use a variety of tire inks to add shine and an attractive appearance to their tires. Such products (as well as those made by yourself) may contain silicone, oils, glycerin and even shoe polish and shoe cleaners.
Every driver must understand: any mixtures on the surface of the rubber can act as lubricants (lubricants) and negatively affect the friction properties of the tire, which determine the deceleration force of the car and, as a result, worsen handling and increase braking distance, which is unacceptable in any season, and especially in winter critical.
And this is another reason for the recommendation to break in winter tires even before the onset of cold weather: at positive temperatures and on asphalt that is not bound by ice, the process of removing foreign compounds from the surface of the rubber will be more effective.
6. Psychological factor
Another important argument in favor of running-in is the psychological factor, the need to mentally adjust to the different behavior of the tire on the road. This factor is relevant for both new and used tires.
And it is very important not to postpone the clarification of the last two factors until the day of difficult weather conditions and difficulties on the road.
conclusions
Summarizing all of the above, we can unequivocally say that both new and used winter studded tires should be run in. The answer to the question whether running in friction Velcro tires is necessary will also be an unequivocal yes - after all, this is also rubber, with exactly the same properties, the same pros and cons.
Many of the above reasons for breaking in winter tires are just as relevant for another season - when changing tires from winter to summer. Whether they are new or used, they have been stored and you have become unaccustomed to them, so it is also recommended to break in summer tires.
The need for running-in is not a myth: this simple process will allow you to avoid unforeseen unpleasant situations associated with changed behavior of the car on the road, prepare and refresh the sensations of driving on completely different tires, protect yourself from an unsuitable or low-quality tire model, as well as extend the life of the tire itself and anti-skid spikes. And extending the service life of tires means direct savings .
Sharp acceleration, braking and lateral drift are harmful for new, unbroken tires of any type: summer, winter and all-season, studded and friction, as well as for those tires that were stored between seasons.
Both regulatory documents, tire manufacturers, stud companies, and experienced drivers unanimously recommend that winter tires be pre-runned at a calm pace, at low speeds, and before the onset of cold weather.

How to properly break in new tires: tips and tricks
4 059
CategoriesUseful tips
An interesting question that many motorists ask: “do new tires need to be broken in”? Some people, however, don’t think about it, they simply put on new tires instead of worn ones and drive like yesterday. But in the first couple of weeks, such people complain about poor braking and handling, and after that, for some reason the tires get back to normal by themselves.
The thing is that during this time the tires were broken in, although not according to the rules. So is it necessary to do this, and if so, how correctly? Let's try to figure it out.
The design of car tires is not as simple as it seems at first glance. It contains several layers of rubber, textile and steel. In order for these components to “work” together, a certain period must pass during which the tire will be under pressure and in motion.
In addition, the tire has a technological lubricant with which it is coated during vulcanization so that the tires do not stick to each other during storage. Naturally, until the lubricant is erased from the tread, traction will be reduced.
It is enough to drive several hundred kilometers on new tires at a calm pace for them to break in. During this period, you should not brake sharply or take turns at high speed. Running in winter and summer tires has its own nuances.
Running in summer tires
Summer tires break in much easier than winter tires. To reveal the full potential of the grip qualities of summer tires, it is enough to very carefully drive one hundred kilometers on hard surfaces on it. This distance will be enough to “grind in” the rubber to the road. Do not accelerate sharply or make sudden maneuvers during break-in.
Running in winter tires
The tread of a winter tire is much deeper than that of a summer tire; the dynamics of the car in the new “winter” are different from the new “summer”.
In addition, the winter tread pattern is designed to work effectively not only on the road, but also in deep snow and ice.
Running in winter tires involves not only erasing the technological lubricant, but also should familiarize the driver with the behavior of his car on a slippery road. Running in studded tires has its own characteristics.
Non-studded tires
The first hundred kilometers on Velcro must be carefully driven at a speed no higher than 80 km/h. Over this distance, the lubricant will leave the wheels. After this, for the next couple of hundred km you can accelerate to the speed allowed by the tire design (see the corresponding index on the sidewall). But it’s still worth accelerating smoothly, and it’s also worth going into turns and braking smoothly.
Studded tires
The specificity of running in such winter tires lies in the process of installing the studs into their seats under load. If you do this incorrectly, you will simply lose all the thorns very soon.
It is worth putting new studded tires on your car even before the first snow, and even more so - ice. You should face winter on well-run-in tires.
It would seem, why such difficulties when running in studded tires? To understand this, you need to study a little about their production technology.
To make studs, a tungsten carbide needle is used, from which 90-100 studs are cut into one wheel.
The needle is inserted into a cylindrical metal groove (housing) and together with it is mounted on the wheel. To facilitate the process of soldering metal to rubber, the mounting holes are lubricated with a special compound.
Next, the rubber is moved apart, a spike is inserted, which will now be held by the compressed rubber.
During the first few hundred kilometers of driving, the studs will “settle” into place: they will rise somewhere, sit deeper somewhere, etc. During this time, the lubricant in the mounting holes should still evaporate.
The first 500 km should be driven very carefully - no faster than 60-70 km/h. Of course, there can be no talk of sharp accelerations and sudden braking.
Otherwise, the service life of the tires will be greatly reduced, and the number of studs on them will be significantly reduced in the first winter.
Some modern studded tires even have special run-in indicators that show up to what point the tires need to be used in a “gentle” mode.
2 more rules
• Balancing . The wheels must be carefully balanced; for this you need to visit a wheel alignment stand.
This is done to avoid unnecessary vibration that impairs motion control. Also, if there is an imbalance, the tire protection wears out more, which affects the service life.
Therefore, if you want to ensure long and reliable service for your tires, pay special attention to balancing.
• Pressure . The tires should be inflated by a professional who knows the amount of air that is suitable for your car. You should not follow the rule “the stronger the better.” A pressure mismatch will have a bad effect on the handling and driving performance of the car.

Running in winter studded tires
Studded tires are one of the types of winter wheels.
Metal spikes are applied to the working surface of this type of rubber in a certain order, which, in turn, are necessary for better adhesion of the wheels to the icy surface of the road surface.
Not every car owner knows that studded tires, like other types of wheel tires, should be run in before use, that is, subjected to gentle use.
How should new studded tires be broken in and why is it even necessary? – find out below.
Is it necessary to break in studded tires?
In fact, running in tires is necessary not so much for the tires themselves, but rather for the driver of the car.
Any new tires initially behave a little unusually on the road, that is, they grip the road differently and react to different road surfaces.
That is why, in order to adapt a little, the driver must first observe a gentle mode of using the car. And it will be useful not only for him. After all, new studded tires have one nuance on which its reliability depends. Let me explain.
Any winter tires have a porous surface (special slots are made on the tread). When installing spikes into it, for a more durable fastening, a lubricant is used, which, during sudden aggressive use, can become clogged in these very pores. As a result, studded tires may simply lose their properties.
And to prevent this from happening, this tire needs to be run in.
How to break in studded tires? Important points
- Running in tires, especially winter tires, should be carried out before the onset of the season, that is, before the onset of cold weather. After all, as mentioned above, the lubricant that is used in this rubber must be completely erased from the surface of the latter.
- The next important point is how long does it take to break in winter studded tires? So here it is. Absolutely any new tires: be it summer, winter or studded, must be run in for at least 500 km.
- Studded tires do not like high speeds, so it is advisable to run them in without exceeding a speed of 70 km/h. By the way, this type of tire also does not like too sharp starts and braking.
- A little trick: on all new tires you can see a colored stripe, which is, in a sense, an indicator of the running-in of the rubber. As soon as it wears off, you can finish running in the tires.
I also advise you to read the article - spikes or Velcro, which is better.
