Tire pressure in winter should be checked at least once every two weeks, as well as with a sharp drop in air temperature. The manufacturer of the machine indicates in the operating instructions what tire pressure the winter vehicle should have. A properly inflated tire optimizes fuel consumption and promotes safe driving. It would seem that small deviations from normal values can lead to such consequences as uneven tread wear, and, accordingly, in the future to reduce tire service life.
It should be remembered that at low temperatures the pressure in the tire also decreases. For example, if the tire pressure is 2 bar at a temperature of +20 degrees C, then at 0 degrees C this value will drop to 1.8 bar. Thus, if the tire inflation process occurs at low ambient temperatures, the pressure standards set by the manufacturer must be observed. While when inflating tires in warm rooms, it is necessary to increase the pressure in the winter tires of the car by an average of 0.2 bar. Thus, it is possible to compensate for the difference arising from low temperatures.
It is not necessary to install winter tires only on the axis that is the driving one. Many motorists in an effort to improve the traction properties of their car make a similar mistake. Despite the seemingly reasonableness of such a solution, a similar option for installing winter tires is not able to provide optimal traction properties of wheels with the road in winter.
In turn, there are certain subtleties in the question: “What should be the pressure in the tires in winter?” Based on logical conclusions, we can conclude that in the case of installing low-profile tires on the car, it is recommended to pump them a little so as not to make a “big shot” on wheels . Also, due to a small pumping of the wheel, the coupling characteristics of tires with icy roadbed significantly increase, thereby it is possible to increase the dynamic properties of the car.
When installing soft rubber, it is very important to ensure that the tire pressure in winter is not too low. The low coefficient of pressure for such rubber contributes to the rapid wear of the tires and turning them into "rags." It also creates a fairly high percentage of probability that the wheels will burst on the road. It should be remembered that having pumped the wheels, you increase the load on the suspension of the car.
In winter, tire pressure should be checked on average once a month. In order for various factors not to influence the measurement accuracy, you should wait until the tire becomes cold. When driving, the degree of pressure can increase up to 20%, on the basis of this, all measurements are advised to be made after at least two hours after the end of the trip.
There is a widespread opinion: "On slippery road surfaces, you need to reduce the pressure in the wheels in order to increase the grip of the tires." This statement is fundamentally wrong due to the decrease in specific pressure on the road surface, due to the increase in the area of the contact spot with the road, the coupling characteristics of tires on slippery roads are deteriorating by an order of magnitude. Another reason why you should not reduce tire pressure is a possible risk of damage to the rims during a collision with any unevenness due to insufficient elasticity of the tire itself.
Tire pressure can be measured using a special device - a manometer. This device is best purchased with the pump. In general, it is necessary to make sure that the tires in your car are moderately inflated, especially in the cold season, because this will ensure optimal grip and a smooth ride.
