Abstract: A pneumatic tire having an outer surface of a tread portion divided into a tread pattern by grooves, in which each of the grooves has an intersect portion and an angle of an island portion surrounded by said intersect portion is different from that of another part at the same island portion. In such a tire, running performances on dry road are improved by making a distance in radial direction from an outer surface of the tread portion to a bottom of the groove at the intersect portion larger as the angle becomes smaller.

Abstract: An improved tire tread has tread elements which form a tread pattern exhibiting two or more peripheral grooves and a plurality of transverse grooves extending inward from the outer (ground engaging) surface of the tread. Preferably the transverse grooves extend across the peripheral groves, and there are at least four of the peripheral grooves. Along at least a major portion of one upper side of chosen ones of such grooves, the tread elements defining such groove side are formed with serrations extending inward of the groove from the tread surface at an acute angle to a radius of the tire and terminating short of the base of the groove. The serrated surfaces define an upper portion of the groove as an opening of increased area at the upper part of the groove intersecting the tread surface, and present a substantially increased traction area along the outer or open top of the groove. In modifications of this tread, the serrations may be along one side of one or more of a plurality of peripheral tread grooves, or the serrations may be may be along opposite sides of such one or more grooves.
