PROBLEM TO BE SOLVED: To make dry control stability and snow-road control stability compatible at high level.SOLUTION: Tread pattern parts P1 and P2 at one side and at the other side of a tire equator Co form line symmetry shapes positionally displaced from each other in a tire circumference direction. The tread pattern parts P1 and P2 comprise inclined lateral grooves 3, and inner and outer jointing grooves 4 and 5 which joint the inclined lateral grooves 3 and 3 adjacent in a circumference direction. The inclined lateral grooves 3 incline and extend to one side in the tire circumference direction, from outside of a grounding end TE to an inner end near the tire equator. The inner and outer jointing grooves 4 and 5 are different in an inclination direction from the inclined lateral grooves 3. The inclined lateral groove of the tread pattern part P1 at the one side and the inclined lateral groove 3 of the tread pattern part at the other side are connected to each other by a center joining groove 6 which crosses the tire equator Co.SELECTED DRAWING: Figure 1 |
