IMPROVED CONSTRUCTION FOR RUNFLAT TIRE

摘要

A low-aspect-ratio pneumatic radial ply tire (50) having a tread (52), a carcass (61) with two sidewalls (77, 78), a single radial ply (70) reinforced with inextensible metal cords, two annular beads (36a', 36b'), and a belt structure (58) located radially between the tread and the radial ply structure (56). Each sidewall (77, 78) is reinforced with a single wedge insert (59a, 59b) having a thickness of between about 50 % and about 90 % of the total sidewall thickness and a section height of between about 60 % to about 110 % of the section height.
