The ornamental design for a tire tread, as shown and described.
FIG. 1 is a perspective view of a tire tread showing my new tire tread
design, it being understood that the tread pattern of the tire tread is
repeated over the outer circumference and shoulder of the tire, the
opposite side being the same as that illustrated; and,
FIG. 2 is a enlarged fragmentary front elevation view of my new tire tread
design thereof.
The broken line disclosure of a tire sidewall and inner bead is for
illustrative purposes only and forms no part of the claimed design.
