First of all, it is necessary to pay attention to the compliance of the tire pressure with the prescribed value, and it is necessary to check the tire pressure at least once every 4 weeks.
Check the pressure only when the tires are cold. The fact is that when driving fast, the tires heat up and the pressure in them increases. However, it would be completely wrong to release air from tires that are heated in this way.
When tire pressure is too high, the middle part of the tread wears more because it flexes more when the tire pressure is high.
If the tire pressure is too low, the shoulders of the treads will press more firmly against the road surface, while the middle part of the tread will bend inward. This results in increased wear of the shoulders of the treads.
For the front wheels, slightly increased wear of the shoulders of the protectors compared to their middle is normal. Moreover, due to the slope of the road surface, the wear of the shoulders of the protectors facing the middle part of the road may be more pronounced (for the left wheel - on the outside, for the right wheel - on the inside).
Saw-tooth wear of the treads is usually caused by overloading the vehicle.
Incorrect wheel alignment and imbalance also cause the typical tire wear pattern indicated in the fault diagnosis.
