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 patternis repeated throughout the
circumference of the tire, the opposite side being substantially the same
as that illustrated; and,
FIG. 2 is an enlarged fragmentary plan view of the tread pattern of FIG. 1
showing my new design.
The broken line disclosure of a tire sidewall and inner bead is for
illustrative purposes only and forms no part of the claimed design.
