Tire tread


FIG. 1 is a perspective view of a tire tread showing our new tread design, it being understood that the tread pattern is repeated uniformly throughout the circumference of the tire with the opposite side being a mirror image of the side shown;

FIG. 2 is an enlarged fragmentary front elevation view of the tire tread illustrated in FIG. 1; and,

FIG. 3 is a front elevation view thereof, wherein the rear elevation, top plan and bottom plan views are the same.

In the drawings, the dark stippled surface shading represents the recessed portion of the tread grooves, having a depth as best shown in FIG. 3.

The broken line showing of a tire sidewall and inner bead is for illustrative purposes only and forms no part of the claimed design.
