Pneumatic radial tire with full-width band and axially spaced edge bands

摘要

A pneumatic radial tire comprises a breaker belt disposed radially outside the carcass having at least two cross plies of high elastic modulus cords laid at an inclination angle of from 15 to 30 degrees with respect to the tire equator, and a band belt disposed radially outside the breaker belt and comprising a full-width band and a pair of axially spaced edge bands, wherein the full-width band is made of low elastic modulus organic fiber cords arranged substantially parallel to the tire equator. The edge bands are made of high modulus organic fiber cords arranged substantially parallel to the tire equator, whereby the high speed durability and cornering performance are improved.
