ABSTRACT:
To prevent tire unbalanced abrasion, that is, tire unbalanced rigidity between the acute angle corners and the obtuse angle corners of blocks forming a tire tread pattern, without decreasing the tire drainage and increasing tire pattern noise, block side walls extending along the main circumferential grooves are sloped down to the bottom of the main grooves in such a way that an inclination angle between the tread surface normal line and the block side wall increases gradually from the obtuse angle corners of the blocks to the acute angle corners thereof. Preferably, the inclination angle is 8 degrees at the obtuse angle corner and 25 degrees at the acute angle corner on the wide main circumferential groove, and 7 degrees at the obtuse angle corner and 13 degrees at the acute angle corner on the main circumferential grooves adjacent to the wide main groove.
