On the front wheels, it should be considered normal to have slightly more wear on the edges of the tires compared to the central part. In addition, due to the inclination of the roadbed, wear on the edge of the tire facing the center of the road (left wheel has outer edge, right wheel has inner edge) maybe more.
Uneven tire wear in most cases is the result of too low or too high tire pressure. However, this may be due to incorrect installation of the wheels or their poor balance, as well as the result of a malfunction of the shock absorbers or disks.
Sawtooth wear of the tire tread is usually the result of overloading the vehicle.
Tire pressure should be checked at least once a month.
Tire pressure is monitored on cold tires. Tire pressure increases when driving fast due to heat from friction on the road surface. But this is not a reason for lowering tire pressure.
With too much pressure in the tires, the central part wears out faster, as it is more arched.
If the pressure is too low, the edges of the tires wear out more due to the greater compliance of the central part of the tire.
Incorrect wheel alignment or imbalance gives a characteristic wear pattern, from which these shortcomings are easily identified.
