And What Will Happen If You Don’t

Experienced drivers advise to be extremely careful when driving on new winter tires, because at first it behaves rather strangely. For example, it can easily slip at a critical moment on frozen asphalt, especially if it is velcro.

According to the manufacturers, this behavior is associated with the peculiarities of the manufacture of the product and it is recommended to go through a short run-in after the purchase. Only after such adaptation can you start driving as usual. But how long is this period?

Usually on new tires, you will notice small rubbery hairs on the tread. They appear due to the production process of automotive rubber. At the final stage, the blank of the future wheel goes into the vulcanization chamber. Soft rubber is poured into a mold and squeezed there, thus obtaining a tread pattern.

And the excess, along with excess air, comes out through special technological holes, like through a colander. It is from these surpluses that the hairs are obtained. Among other things, the walls of the mold are lubricated with a special compound that prevents material from sticking before placing the workpiece.

Otherwise, the finished tire simply cannot be pulled out from there without damage. This technological lubricant, like the “bristle” of small hairs, remains on the finished tires. As for the hairs, their presence is rather useful for the tire.

Michelin conducted special tests at its winter training ground in Ivalo, Finland and found that the villi help when driving on ice. Their presence improves grip by 2% in the transverse direction, and by almost 8% in the longitudinal direction. The hairs act in a similar way to spikes, although not as effectively – they tuck under the protector and cling to the soft surface of the coating.

But the remainder of the technological lubricant affects the tire negatively. It clogs into the pores of the rubber, impairing its grip properties. At a critical moment, the tire may slip unexpectedly. Therefore, it is necessary to roll in the wheels for some time – the oil film should come off along with the top layer of rubber.

Studded wheels also need running-in, although their performance on ice does not deteriorate. There, the problem lies in the insufficiently strengthened fastenings of the metal teeth. Before installing the studs at the factory, the nests for them are also treated with a special lubricant.

The grease stays there for a while, preventing the teeth from snuggling. And until it comes off, you should drive more carefully for some time – otherwise, some of the studs may fall out already in the first days after purchase. The break-in process is not complicated – it is enough just to avoid sudden acceleration and deceleration, not to accelerate over 80-90 km / h. It is not recommended to enter corners at high speed.

The most quiet mode must be observed during the first 300 km. Then you can move faster, but without strong overloads, and also avoiding collisions with curbs, sharp rubble and other obstacles. After 1,000 km of run, it is necessary to balance the wheels in order to compensate for the shift in the center of gravity after the tire shrinks on the disk. Then you can ride at your usual pace.
