The ornamental design for a tire tread, as shown and described. |
FIG. 1 is a side perspective view of a tire tread showing our new design, it being understood that the tread pattern is repeated throughout the circumference of the tire tread, the opposite side being substantially the same as that shown;
FIG. 2 is a front elevational view thereof;
FIG. 3 is a side elevational view of the right side thereof, the opposite side being identical; and,
FIG. 4 is an enlarged fragmentary front elevational view thereof.
The broken line showing of the tire inner bead and the peripheral boundary between the tire tread and the sidewall in the drawing is for illustrative purposes only and forms no part of the claimed design.
