CARCASS FOR LOW PROFILE TIRE CARCASS FOR LOW PROFILE TIRE

摘要

A pneumatic tire for high speed running vehicles having an aspect ratio of 0.25 to 0.75 and a carcass composed of at least two plies each formed of a textile cord layer including parallel cords crossed with those of the other ply. The carcass satisfies the following conditions: (1) The cord has an initial modulus of at least 100 g/denier; (2) The cords are embedded in rubber having a modulus of elasticity at 300% elongation of 100 to 250 kg/cm2; (3) The cords are inclined at an angle of 20 DEG to 40 DEG with respect to the equatorial plane of the tire; (4) The cords have a gap ratio in each ply of 10 to 65% and a gap ratio between adjacent plies of 22 to 83%.
