4.1.9. Evenly worn-out tires

Requirements imposed to tires constantly become tougher.
The following factors are the reasons:
– the growing mass of the car;
– high speeds;
– high traffic safety.
High load of the tire for the natural reasons involves bigger wear.
Style of driving significantly influences wear of tires. Therefore at complaints to wear of tires and evenly worn-out drawing of a protector such tires do not fall under a guarantee.
The actual service life of the tire comes to light only with a residual height of the drawing of a protector of 2 mm.
