Abstract

PURPOSE:To improve the high speed durability of the titled tire of a specified flatness by arranging a run flat strip of a crescent cross section made of low heat generating rubber with specified maximum thickness and an overlapping amount on the inner surface of the tire. CONSTITUTION:A run flat strip 7 made of low heat generating rubber of a crescent cross section having a maximum thickness tr of 1.0-1.5 times of a side wall thickness ts at the same position is arranged inside the side wall 3. Overlapping portions L1, L2 of 10mm or more are formed between a belt 5 and a bead apex 6. With this constitution, while the high speed durability in normal driving is improved, the high speed durability in the case of flattening is also improved.
