TIRE

A tire 2 includes a tread 4 and a band 16. The tread 4 has an outer surface 4G including a crown portion 64, a pair of middle portions 66, and a pair of shoulder portions 68. The crown portion 64 has a contour represented by an arc having a radius TR1 not less than 5 times and not greater than 7 times an axial width Wa of a ground-contact surface of the tire 2 in a standard state. The band 16 includes a band cord 56 composed of an organic fiber cord. At a position corresponding to 70% of a maximum width SW of the tire 2 in the standard state, the band cord 56 has a contraction ratio SRs not less than 70% and not greater than 130% of a contraction ratio SRc of the band cord 56 on an equator plane of the tire 2.
