Uneven tire wear is most often attributed to low or high tire pressure or wheel imbalance, as well as defects in the shock absorber and wheel rim.
Sawtooth wear of a tire profile is usually the result of overloading the vehicle.
First of all, you should monitor the prescribed tire pressure and check the pressure at least once every 4 weeks.
Check the pressure only in cold tires, the pressure in the tire increases when warmed up during fast driving. However, it is completely wrong to release the pressure in a warm tire.

At higher pressure, the middle of the working surface of the tire wears out more, since the curvature of the profile increases due to the high internal pressure.
At low pressure, the tire adheres to the road more with the edges of the working surface, and the middle of the profile bends inward. This causes increased wear of the edges of the tire profile.
Incorrect wheel alignment and imbalance produce characteristic wear patterns that are noted in the tire fault diagnostics section.
