The ornamental design for a tire tread, as shown and described.
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.
