PROBLEM TO BE SOLVED: To improve steering stability without damaging ride comfort. SOLUTION: A profile of a tire outer surface is formed by a plurality of arcs having a radius of curvature gradually reduced from an intersection of the tire outer surface and a tire equatorial plane to a ground contact end side. A tread part 2 includes a center vertical groove 13 continuously extended to a tire peripheral direction and having a groove width GW1 of 15-25 mm, an outer pattern part Po provided on the vehicle outer side thereof, and an inner pattern part Pi provided on the vehicle inner side of the center vertical groove 13. The outer pattern part Po includes a large block row 20 wherein large blocks B1 are aligned in the tire peripheral direction. The inner pattern part Pi includes small block rows 23 and 24 wherein small blocks B2 and B3 having the width and the tire peripheral length shorter than the large block B1 are aligned in the tire peripheral direction.
