Abstract: A tread design for a radial tire provides a tread block pattern that reduces the treadwear of the tire. The tread design comprises a plurality of blocks cooperatively formed by circumferential grooves extending around the tire and angularly oriented transverse grooves intersecting the circumferential grooves. The blocks are preferably arranged in three circumferentially extending ribs, wherein each rib is separated from another by a circumferential groove. Each individual block is separated from an adjacent block by a straight transverse groove. Each transverse groove extends at an angle of about 40.degree. to 60.degree. with respect to the circumferential plane of the tire, with the preferred angle being approximately 45.degree.. The tread pattern on the left side tire is the mirror image of the tread pattern on the right side tire.
