PROBLEM TO BE SOLVED: To provide a pneumatic tire, particularly that with high performance capable of effectively enhancing draining performance without sacrificing other performance. SOLUTION: Divided land parts 8a and 8b are formed by arranging a lot of inclined grooves 7a and 7b extending relative to the tire circumferential direction from a center area 4 toward a tread ground contact ends 5a and 5b on at least approximately half areas 2 and 3 of a tread surface part 1. The divided land parts 8a and 8b has a pair of notch parts 9a and 9b which are formed from the inner land side positions 10 of the divided land parts 8a and 8b toward two inclined grooves 7a1 and 7a2 or 7b1 and 7b2 forming these divided land parts 8a and 8b, respectively, so as to incline to the same direction as the inclined grooves 7a1 and 7a2 or 7b1 and 7b2, decrease heights of the land parts 8a and 8b and allow the surface 11 to widen toward an end. The divided land parts 8a and 8b are substantially divided into two parts: the center land part 12 and side land part 13. |
