<p>TIRE TREAD STRUCTURE A tread for a pneumatic vehicle tire, characterized by improved wear, is disclosed. The tread includes a plurality of lugs separated by grooves and a plurality of circumferentially continuous ribs. Each edge of the lugs and ribs is chamfered. The width of each chamfer as projected onto the radially outward surface of the tread is between about 0.15L and about 0.5L, where L is the dimension of the unchamfered lug or rib measured perpendicularly to the chamfered edge and parallel to the surface of the tread. The depth of each chamfer is between about 0.2Z and about 0.4Z, where Z is the depth of the groove adjacent to the chamfered edge measured to the radially outward surface of the tread. This abstract is not to be taken either as a complete exposition or as a limitation of the present invention, however, the full nature and extent of the invention being discernible only by reference to and from the entire disclosure.</p> |
