PROBLEM TO BE SOLVED: To improve straight driving stability and turning controllability in high speed driving. SOLUTION: A ratio Sc/Ss, in which Sc is a central sea area ratio in a central area C having a width of 20% of a tread width TW with a tire equator C0 as its center and Ss is a shoulder sea area ratio in a shoulder area S having a width of 20% of the tread width TW from a tread edge E1, is 1.2-2.0. A ratio Tc/Ts, in which Tc is a central rubber thickness between a breaker and a tread surface 2S at the tire equator C0 and Ts is a shoulder rubber thickness at a shoulder point P3 0.1 TW distant from the tread edge E1, is 1.2-2.0. |
