| Abstract: |
| The static fore-aft stiffness of radial car tire was measured by a tire static load tester with additional tire fore-aft stiffness testing device.The dependence of the static fore-aft stiffness of radial car tire on the radial load，inflation pressure and structure parameters，such as belt width，cap ply rubber and tread gauge was investigated.The results showed that the radial load had little effect on the fore-aft stiffness of tire；the specific fore-aft stiffness increased as the inflation pressure raised；and the structure parameters didn’t have remarkable effect on the specific fore-aft stiffness of tire. |
