Pneumatic tire with tread defined by singularly bent transverse grooves |
摘要 |
A pneumatic tire wherein a plurality of main grooves are provided in a tread of the tire in the circumferential direction thereof with a plurality of sub-grooves connecting these main grooves with each other being provided in the width-wise direction of the tire, wherein each of these sub-grooves is bent in a convex shape facing in the same direction relative to the circumferential direction of the tire, and wherein bending points of the sub-grooves are distributed within those areas in the tread of the tire which extend, respectively, from a tire equator line toward opposite sides of the tire in the width-wise direction thereof over a distance equal to 5 to 25% of the tread ground-contacting width in such a manner that the number of the bending points become substantially equal on either side of the equator line.
