Tubeless bias-ply tire with at least one carcass ply ending near bead core without being wrapped therearound

摘要

A bias-ply pneumatic tire comprises a tire cover having a thread portion, a pair of opposed side walls integral with the tread portion and a pair of opposed bead portions integral with the respective side walls and adapted to firmly engage with associated rim flanges of a wheel rim. Each of the bead portions includes at least one bead core embedded therein. The tire cover includes a bias-ply carcass structure composed of a plurality of carcass plies laid on a bias at a predetermined angle with respect to the midcircumferential plane of the tire. At least one of the carcass plies in the tire cover has its opposed ends each terminating, without being turned up around and anchored to the corresponding bead core, in a region between the corresponding bead core and a lower portion of the corresponding side wall while the other of the carcass plies have their opposed ends each being turned up around and anchored to the corresponding bead core, thereby terminating at a position adjacent the boundary between the side wall and the bead portion.
