METHOD FOR REGULATING TIRE IMPRINT AREA AND TIRE FOR WHEELS OF VEHICLES Russian patent published in 2018 - IPC B60C3/06 

FIELD: transportation.

SUBSTANCE: method for regulating the imprint area symmetry of a tire moving along a straight trajectory, with a camber angle of the wheels, different from zero, includes the following stages: reducing contact pressure acting on the tire (2) in the imprint area at an inner sidewall (in case of a negative camber angle of the wheels) or an outer sidewall (in case of a positive camber angle of the wheels); locating any midline (lm) of the tread band (9) of a tire, located with ensuring its conformity with the imprint area, essentially parallel to the ground. In accordance with the invention, a tire and a wheel for vehicles, in which the midline (lm) of the tread band (9) and the rotation axis (x-x) of the tire (2) form an angle (α) essentially equal to the absolute value of the camber angle (β) of the wheels, are developed as well. The invention also covers the method of manufacturing such tires, where an unvulcanised tire with a symmetrical profile is deformed during the vulcanization and shaping stage, until the specified angle (α), different from zero, is formed between any midline (lm) of the tread band (9) and the rotation axis (x-x) of the vulcanized tire (2).

EFFECT: improved performance of tires.
