What should be the tire pressure in autumn?

There are several important factors to consider when lowering temperatures

Do many people wonder what the car tire pressure should be as the colder weather approaches? At the same time, some drivers are convinced that the wheels should be inflated, while others, on the contrary, consider it correct to let the air out of the tires. We tell you which of the solutions is the only correct one.

In fact, several important factors must be taken into account when choosing the necessary tire pressure under the condition of falling temperatures. First of all, the air temperature. As a rule, with its reduction, the pressure in the tire drops by about 0.1-0.3 atmospheres.

In other words, if the tire, for example, is inflated to 2 bars, then with the onset of cold weather the indicator can easily drop to 1.7 bars. Simply put, it pays to increase the tire pressure by at least 0.2 bar before driving. Especially if a long-distance trip is planned, taking into account the increased speeds.

Also, the load on the car plays an important role. The larger it is, the higher the pressure should be. So it turns out that adding 0.3 bar will not hurt.

But it’s still not worth pumping up the tires a lot. First, as the temperature drops, the elasticity of the rubber layer decreases; secondly, when pumping, the contact patch with the road surface is reduced. Finally, there is a risk of deterioration in handling and a chance for the tire to lose its wear-resistance properties.
In the fall, tires can deflate only when driving on soft ground, for example in mud or unexpectedly fallen snow. To improve traction, it is enough to lower the tire by 0.3-0.5 bar.

In this case, you must make sure that there is the same pressure in each of the tires. Otherwise, the car may lose control even on a slightly wet surface – often the car is pulled to the side when braking.
