ABSTRACT:
A large number of sub-grooves inclining in the same direction as a tire rotating direction of a tire circumferential direction towards the outside of a car and extending in a tire width-wise direction are disposed on a tread surface of a tire the tire rotating direction of which is designated in one direction, and at least one main groove extending straight in the tire circumferential direction is disposed in an inside region of the tread surface inner than a tire center line. Further, semi-main grooves crossing the sub-grooves and inclining in an opposite direction to that of the sub-grooves are disposed at a predetermined pitch in the tire circumferential direction in an outside region of the tread surface outer than the tire center line. In this way, a pneumatic radial tire of the present invention has a block type tread pattern having asymmetric directionality.
