PNEUMATIC TIRE OF VEHICLE Russian patent published in 2020 - IPC B60C11/16 B60C11/11 

FIELD: transportation.

SUBSTANCE: invention relates to pneumatic tire of vehicle with studs for operation in winter conditions. Tire has shaped tread with anti-skid studs (1, 2) arranged in circumferential strips (S_P) of anti-skid studs along tire tread periphery. Each anti-skid stud (1, 2) comprises anti-skid stud body (3) fixed in tire tread rubber material, and anti-skid stud pin (4, 5) protruding beyond tire tread periphery. In the tire tread the first type anti-skid studs (1) and anti-skid studs (2) of the second type are fixed, which differ from each other in the shape of their pins (4, 5) of anti-skid studs. First-type anti-skid studs (1) provide, in particular, improved side force transmission compared to the second type anti-skid studs (2), which provide, in particular, improved transfer of braking and thrust forces as compared to the first type anti-skid studs (1). In at least one anti-skid studs strip (S_P) in the side circumferential area (S_B) and in at least one strip (S_P) of anti-skid studs in central circumferential area (Z) are arranged respectively as first-type anti-skid studs (1) and anti-skid studs (2) of the second type.

EFFECT: improved controllability of the vehicle pneumatic tire on ice-covered soil.
