PROBLEM TO BE SOLVED: To provide a tire superior in durability, with both reduction in rolling resistance and driving stability. SOLUTION: This tire 1A has an annular tread part 2 grounding on a traveling surface, a pair of sidewall parts 3 arranged on the more inner peripheral side than both right-left sides of the annular tread part 2, and a pair of bead parts 4 arranged on the innermost periphery of the respective sidewall parts 3 and installed in a rim part, and is formed by setting a value (TW/SW) being the ratio of a tread grounding width TW to a section width SW in a range of 0.6-0.75. The respective side wall parts 3 are formed of the same rubber material as a rubber material of the tread part 2 up to an area of at least 50% or more of the section height SH with the grounding surface side of the tread part 2 as a reference.
