Abstract
A tire includes, in a tread portion, a pair of shoulder main grooves, a crown region between the shoulder main grooves, and shoulder regions disposed outside of the shoulder main grooves in a tire axial direction. Land ratios of the crown region and the shoulder regions are respectively 40%-60%. In the crown region, a plurality of middle blocks are arranged on both sides of a tire equator, and each middle block has a longitudinal shape in which a length in the tire circumferential direction is larger than a length in the tire axial direction.
