RADIAL RUNFLAT TIRE Russian patent published in 2018 - IPC B60C17/00 

FIELD: automotive engineering.

SUBSTANCE: tire includes a carcass extending between a pair of beads, a side reinforcing rubber layer arranged on tire sidewall and extending in radial direction of the tire along inner surface of the carcass, and at least one inclined breaker-strip layer located in the tire radial direction outside the carcass and including a cord which is inclined to the circumferential direction of the tire. At least on one side in the axial direction of the tire, the end of the inclined breaker-strip layer of maximum width has the greatest width in the axial direction of the tire. The inclined breaker-strip layer of the maximum width and the side reinforcing rubber layer have an overlap, the width of which is at least 15% of the width of the inclined breaker-strip layer of the maximum width in the axial direction of the tire.
