PNEUMATIC RADIAL TIRE |
| 摘要 |
Pneumatic radial tire (1) having improved high speed durability and low flatspot feature, and which has polyethylene terephthalate cap ply reinforcement layer (6). The objective is to provide a pneumatic radial tire (1) wherein the pressure on the belt package (5) is increased at high speed and high temperature by increasing the thermal shrinkage force of the cap ply cord. |

1. A Pneumatic radial tire comprising:
A plurality of polyethylene terephthalate cords; One or more cap ply reinforcement strips; Wherein the cap ply reinforcement strip is formed of the polyethylene terephthalate cords; Wherein the cap ply reinforcement strip is wound onto a belt package: Wherein the secant modulus of the cords is between 2.0 and 2.5 mN/dtex. % at 160° C. between elongations of 3 to 5%; Wherein the thermal shrinkage force of the cords is above 2. mN/dtex at 177° C. (according to ASTM D885); And wherein the cords are obtained by relaxation of 1 to 3% at 220-240° C., and then cold stretching between 1 to 5% at 140-200° C. |
