TIRE

The tire can achieve both cut resistance and mud drainage performance of the sidewall. The tire includes: a tread; sidewalls; and a plurality of side block groups on at least one of the sidewalls. Each of the side block groups protrudes from the sidewall reference plane. Each of the side block groups includes: a first side block; and a second side block. In each of said plurality of side block groups, the fi3 . . . 3rst side block has a groove extending from the second side block toward an inside of the first side block in the tire circumferential direction D In each of said plurality of side block groups, the second side block has a slope whose height from the reference plane S becomes lower toward the first side block, such that the slope extends into the groove of the first side block.
