The present invention provides a pneumatic tire capable of ensuring good braking performance by making an edge effect be fully demonstrated by suppressing upward deformation of edge portions of a block. A block row constituted of plural shoulder blocks 24 is provided on the outer side in the tire widthwise direction of the center rib 16, with a circumferential fine groove 18 diposed therebetween. A block row constituted of plural shoulder blocks 32 is provided on the outer side in the tire widthwise direction of the center rib 26, with a circumferential shallow groove 28 disposed therebetween. In a case where edge portions of the blocks on the lug groove side are deformed upwardly due to frictions between the edge portions and a road surface when a relatively high force is inputted or on a dry road surface, the center rib 16 adjacent to the center blocks 24 and the shoulder rib 26 adjacent to the shoulder blocks 32 work to suppress deformation of the center blocks 24 and deformation of the shoulder blocks 32, respectively. As a result, upward deformation of the edge portions on the lug groove side, of each block, is suppressed, whereby sufficient braking performance can be demonstrated when a relatively high force is inputted or on a dry road. |
