A pneumatic radial tyre comprises a breaker belt (7) disposed radially outside the carcass (6) and comprising at least two crossed plies (7a,7b) of high elastic: modulus cords laid at an inclination angle of from 15 to 30 degrees with respect to the tyre equator (C), and a band belt (9) disposed radially outside the breaker belt (7) and comprising a full-width band (9A) and a pair of axially spaced edge bands (9B), wherein the full-width band (9A) is made of a low elastic modulus organic fibre cord arranged substantially parallel to the tyre equator (C), the edge bands (9B) are made of a high modulus organic fibre cord arranged substantially parallel to the tyre equator (C), whereby the high speed durability and cornering performance are improved. <IMAGE> |
