Abstract
A pair of radial tires consist of two tires each having a tread comprising annular land portions formed by a plurality of circumferential main grooves extending in the circumferential direction of the tire, and rows of blocks formed by extending transverse main grooves inclinedly in the circumferential direction in at least land portions located at axially opposite side edge portions of the tire. Tread patterns of these two tires are asymmetrical and have directional property. Transverse main grooves of each of the tires, which define the rows of the blocks to be located axially inside, are extended inclinedly downwardly toward the inner side of the tread in the width direction as viewed from the front side of the tire. Each of the transverse main grooves of the tire, which define the row of the blocks located axially on the outer side is extended in an almost inverse V-letter shape as viewed from the front side of the tire.
