In a tire 2, a body 24 and side ends 26 are formed by side grooves 22 being formed in edge PT portions of a tread 4. A ratio of a width BW of a belt 12 to a width TW of the body 24 is 0.95-1.00. A width GW of each side groove 22 is greater than or equal to 2.0 mm. A width RW of each side end 26 is greater than or equal to 2.0 mm. A ratio of a depth D1 of each side groove 22 to a depth D of each main groove 30a is 0.6-1.0. A ratio of a distance H from a vertex PP of each side end 26 to the tread surface 28 relative to the depth D is greater than or equal to 0.4.
