FIG. 1 is a perspective view of a tire tread showing my new design, it being understood that the tread pattern is repeated uniformly throughout the outer circumference and shoulder of the tire tread, the opposite side being the same as that illustrated;

FIG. 2 is a enlarged fragmentary front elevation view of the tread pattern of FIG. 1 showing my new design of the tire tread; and,

FIG. 3 is an enlarged fragmentary front elevation view of the tread pattern of an alternate embodiment of a tire tread, it being understood that the tread pattern is repeated uniformly throughout the outer circumference and shoulder of the tire tread, similar to the first embodiment shown in FIG. 1.

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