INFLATED TYRE Russian patent published in 2015 - IPC B60C11/04 B60C11/03 B60C11/117 B60C11/12 B60C11/13 B60C11/16 

FIELD: motor vehicle industry.

SUBSTANCE: treat profile includes first grooves of grouser, that go from the appropriate ends on the external side in the transverse direction of tyre of the first inclined grooves in the first direction in the tyre longitudinal direction, and at angle in the direction of the external side in the tyre transverse direction up to edges of the area of engagement with the pavement, and have angle made with the tyre transverse direction, that is below the angle created with the tyre transverse direction by the first inclined grooves. The second inclined grooves pass from the appropriate ends on the external side in the tyre transverse direction of the first inclined grooves in the first direction in the tyre longitudinal direction, and at angle in the direction of the internal side in the tyre transverse direction. The third inclined grooves pass from the appropriate intermediate points on the first grooves of the grouser in the first direction in the tyre longitudinal direction, and at angle to in the direction of the external side in the tyre transverse direction, and have angle made with the tyre transverse direction exceeding the angle made with the tyre transverse direction by the first grooves of the grouser. Each third inclined groove closes not reaching the other first groove of the grouse, located adjacent with the first groove of the grouser in the first direction.

EFFECT: improved operation parameters of the tyre on ice, snow and wet pavement.
