PROBLEM TO BE SOLVED: To provide a pneumatic tire capable of improving the partial abrasion restricting effect while restricting the lowering of the wet performance and the on-ice and snow performance. SOLUTION: A center block 26 is provided with lower parts 30 lower than a tread curve surface, second blocks 34 are provided with lower parts 38, third blocks 42 are provided with lower parts 46, and shoulder blocks 52 are provided with lower parts 54 so as to restrict the partial abrasion of each block. The center block 26 formed with a small quantity of the lowering in each corner part and capable of obtaining the high edge pressure is arranged at the center of a tire having the high tread pressure, and the shoulder block 52 formed with a large quantity of lowering in each corner part and having the high partial abrasion restricting effect is arranged outside in the cross direction of the tire easy to be partially worn. With this arrangement, lowering of the wet performance and the on-ice and snow performance can be restricted and while the partial abrasion restricting effect can be improved. |
