PROBLEM TO BE SOLVED: To provide a tire making compatible insurance of traction performance and suppression of uneven wear of a second land part. SOLUTION: A center main groove 20 extending in a zig-zag form in a tire circumferential direction U and shoulder main grooves 22L, 22R linearly extending in the tire circumferential direction U are formed on a tread part 78. As a result, the second land parts 30L, 30R positioned between the center main groove 20 and the shoulder main grooves 22L, 22R respectively are formed. On the second land part 30L, a land part edge 30EL at an outer side in a width direction is linear in plan view, and a land part edge 30FL at an inner side in a width direction is a zig-zag form in plan view. It is similar regarding the second land part 30R. Further, on the second land parts 30L, 30R, second lateral grooves 40L, 40R are formed respectively, and on the shoulder land parts 80L, 80R adjacent to an outer side in a width direction of the shoulder main grooves 22L, 22R, shoulder lateral grooves 70L, 70R are formed respectively.
