Shift of wheels
On vehicles with front-wheel drive as a result of a greater load on the front tire tread wear occurs earlier than the tires of the rear axle. To equalize the lifetime of all 4 tires of the car is recommended to swap the front wheels with tires on the rear axle and vice versa. At tire with directional tread be careful that they are not overturned. The longer the tire is operated at a certain wheel of the car, the more it is aligned, so the permutation wheels recommended to run at frequent intervals, such as every 5,000 km. The diagonal permutation is only aimed at the tires without tread. This kind of transposition is justified especially when the tread is worn as a track sawtooth If tire wear in the form of a sawtooth track progresses tread is worn more than 50%, this type of rearrangement will give only a small increase range and practically not justified. The elasticity of the tread blocks is deteriorating and sawtooth wear ceases to progress.
