<P>PROBLEM TO BE SOLVED: To suppress an increase in tire mass, an increase in vertical spring property, and deterioration in uniformity while improving a run-flat property, and to prevent a drop of tire productivity. <P>SOLUTION: A run-flat tire includes a carcass 6 formed of at least one carcass ply, a belt layer 7, a side reinforcing rubber layer 9, and bead apex rubber 8. An apex height A1 on one side is higher than an apex height A2 on the other side, and an inner end height B1 on one side is higher than an inner end height B2 on the other side. A bead 4 on one side and a bead 4 on the other side have the same tire thicknesses at the same position in the tire radial direction in a tire radial direction area where at least the bead apex rubber 8 and the side reinforcing rubber layer 9 are arranged. <P>COPYRIGHT: (C)2013,JPO&INPIT |
