PROBLEM TO BE SOLVED: To provide a run-flat tire which is improved in run-flat durability without impairing a favorable riding comfort at normal traveling.SOLUTION: In this tire 2, a load support layer 20 extends up to the inside of a radial direction of a belt 12 from a side part 22. When a distance in an axial direction from an equator up to an outer end of the load support layer 20 is set as Wi, and a distance in the axial direction from the equator up to an end of the belt 12 is set as Wb, a ratio (Wi/Wb) of the distance Wi with respect to the distance Wb is not larger than 0.75. Preferably, the load support layer 20 comprises a first layer 46 which extends up to the vicinity of the end of the belt 12 at the side part 22, and a second layer 48 which extends from an outside end of the radial direction of the first layer 46 toward the inside of the axial direction at the inside of the belt 12 in the radial direction. The hardness H2 of the second layer 48 is higher than the hardness H1 of the first layer 46.SELECTED DRAWING: Figure 1 |
