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 repeats throughout the outer
surface and shoulder circumference of the tire tread, the opposite side
perspective view being identical thereto; and,
FIG. 2 is a enlarged fragmentary front elevation view of the tread pattern
of the tire tread thereof.
In the drawings, the dark stippled surface shading represents the recessed
portion of the tread grooves, having a depth as best shown along the upper
right edge of FIG. 1.
The broken line disclosure of the tire sidewall and inner bead is for
illustrative purposes only and forms no part of the claimed design.
