First of all, it is necessary to ensure that the tire pressure is within the specified value, and it is necessary to check the tire pressure at least once every 4 weeks, and also every time before long trips.
Only check pressure when tires are cold. The fact is that when driving fast, the tires heat up and the pressure in them increases. However, it is absolutely wrong to bleed air from tires heated in this way.
It is normal for the front wheels to have slightly increased wear on the tread shoulders compared to their middle. Moreover, due to the slope of the roadway, the wear of the tread shoulders facing the middle part of the road may be more pronounced (for the left wheel - from the outside, for the right wheel - from the inside).
Uneven tire wear is mostly the result of too low or too high tire pressure. It can also be caused by incorrect adjustment or balancing of the wheels, as well as poor condition of the shock absorbers or rims.
If the tire pressure is too high, the middle part of the tread wears out more, since it bends outward more with high pressure inside the tire.
When the tire pressure is too low, the shoulders of the treads adhere more strongly to the road surface, while the middle part of the tread flexes inwards. The result is increased wear on the tread shoulders.
The sawtooth wear of the protectors is usually caused by overloading the car.
