Increased wear on the tires of the wheels, especially the tread shoulders, is normal. This is especially clear for the left wheel - from the outside, for the right wheel - from the inside. Uneven tire wear is evidence of deviations in tire pressure from the recommended one, incorrect setting of the wheel toe angle, imbalance of wheels, poor condition of shock absorbers or rims. Sawtooth wear of the tread indicates an overload of the car. These points are described in more detail in the section «Operations» this guide.
