PNEUMATIC TIRE WITH ANNULAR CONCAVITY OF SIDE WALL Russian patent published in 2021 - IPC B60C17/08 B60C13/00 B60C9/00 

FIELD: automotive industry.

SUBSTANCE: pneumatic tire has inextensible tread (30), on each side of which there are two shoulder areas (34) and two inextensible onboard areas (36) for mounting tire on wheel, note here that every side area is connected via sidewall with appropriate side area. Each sidewall comprises first section (38) extending inward along the width of the tire from one of bead areas (36) to bending region (40), and second portion (42) extending outward along tire width from bending region (40) to corresponding one of shoulder areas (34). Inextensible configuration (44, 46, 56) for limiting perimeter and radial reinforcing structure (48, 50, 52) are connected to first section (38) of each side wall and thus limiting radial bending of first section (38) and maintaining annular concavity between bead area (36) and shoulder region (34).

EFFECT: technical result is improved tire operating characteristics.
