Pneumatic tires and molds for tire molding.

Abstract

To provide a pneumatic tire which can improve drive performance and wet performance.SOLUTION: This invention is a pneumatic tire 10 having a tread 20 including a block 30 where a sipe 40 is formed, has a plurality of dents 41 formed on one wall face of the sipe 40, and gets the dents 41 increased in volume from the equator CL toward the shoulder side SH over the whole tire width of a tire axial direction X. A plurality of dents 41 with the same volume are formed in the sipe 40 of one block 30 of a plurality of blocks 30.SELECTED DRAWING: Figure 3

Claims
