PNEUMATIC TIRE Russian patent published in 2018 - IPC B60C11/117 B60C11/03 

FIELD: automotive engineering.

SUBSTANCE: pneumatic tire (1) includes transverse connecting grooves (3, 3a, 3b) and circumferential grooves (4). In the shoulder area of the protector part, a transverse connecting groove (3A) is located between the two V-shaped cross grooves (2A, 2b), neighbouring in the direction along the tire circumference, and runs from the tire edge in the direction of the equatorial plane (CL) of tire. In the central area of the protector part, the transverse connecting groove (3a) communicates with the V-shaped cross groove (2b) from the protruding side of the V-shaped profile of the pair of V-shaped cross grooves (2a, 2b) and does not communicate with the other V-shaped cross groove (2a) from this pair. The circumferential grooves (4) are located in the shoulder area of the protector portion and extend in the circumferential direction of the tire, and communicate with the V-shaped cross grooves (2) and the transverse connecting grooves (3).

EFFECT: improved braking performance when driving on snow and performance when driving on wet roads.
