PNEUMATIC TIRE Russian patent published in 2019 - IPC B60C11/03 B60C11/00 B60C11/12 

FIELD: automotive industry.

SUBSTANCE: invention relates to the automotive industry. Ground-engaging groove (15) is made so that its section determining the side of block (20) in the direction of movement in the tire rotation direction is inclined to the side opposite to the direction of movement in the tire rotation direction, since this section extends outward in transverse direction of tire from side of equatorial line (CL) of tire. Of the plurality of small blocks (40) defined in block (20) by means of narrow grooves (30), small block (40) adjacent to ground-engaging groove (15) defining the side of block (20) in the direction of movement in the tire rotation direction, and with longitudinal main groove (10) determining side of equatorial line (CL) of block tire, is block (41) located in direction of movement, and small block (40), having a section located on the rear side of block (20) in direction of tire rotation, is block (42) located opposite direction of movement. From small blocks (40) block (42) located opposite direction of movement, has larger surface area than block (41) located in direction of movement, and each of intermediate blocks (43) has larger surface area than block (42) located opposite direction of movement.

EFFECT: improved resistance to uneven wear and reduced noise with simultaneous preservation of operational characteristics when driving on snow and ice.
