A tire (1) wherein at least a circumferential groove (11) of grooves formed in a tread surface (10) comprises a continuously waved bottom surface whose top does not reach the tread surface, which extends partially or entirely along the circumference of the groove. The tire of this invention may prevent a holding of water due to its groove, increasing the ability to discharge water. It is therefore possible to retain grip performance of the tire. Particularly when traveling in rain, the tire effects a reliable hydroplaning prevention avoiding an increase in the proportion of the groove. |
