PNEUMATIC TIRE

To provide a pneumatic tire in which noise can be reduced without changing the basic design of the block pattern. [0002] A chamfered portion 24 is provided at a tire widthwise-direction outer side end 18A of a leading edge 18A of a block 18. When the tire rolls and the block 18 contacts a road surface, first, with respect to the leading edge 18A, a flat portion 22 contacts the ground, and then the chamfered portion 24 contacts the ground. Because the height of the chamfered portion 24 gradually decreases towards the tire widthwise-direction outer side end, the leading edge 18A at the chamfered portion 24 gradually makes contact with the road surface, whereby force input that generates sound is dispersed in terms of input timing and it is possible to suppress the generation of noise (mainly a striking sound) at the initial state of the block 18 contacting the road surface. Furthermore, by changing the tire widthwise-direction position of the flat portion 22 in a tire circumferential direction, it is possible for the entire block to gently receive stress generated at the time of rolling, whereby it is possible to suppress the level of noise generated by the block 18 at the time the block 18 contacts the ground at a low level.
