Abstract

PURPOSE:To improve driving stability in a high speed, straight running stability in a superhigh speed and durability by arranging an auxiliary layer in the outer side of a breaker while forming a tread surface in the shape of a double- radius structure and optimizing the shape of the tread surface. CONSTITUTION:A tire 1 arranges in its bead part 3, side wall part 4 and tread part 5 a carcass 6 folded returning in the periphery of a bead core 2. The tread part 5 respectively arranges a breaker 7 in the outer side of the carcass 6 further an auxiliary layer 8 in the outer side of the breaker 7. While the tire 1 forms the tread part 5 from a crown side part 16 and a shoulder side part 17 with their respective radius of curvature R1, R2 different from each other. Here the tire 1 respectively sets ratio of length WP between overlapping points P of each part 16, 17 to tread width WT between tread part end edges (t) to 0.65-0.75, first height in the radial direction to 6-10mm, ratio of this height to the second height in the radial direction to 0.4-0.6 and flatness H/W to 0.6 or less.
