The ornamental design for a tire tread, as shown and described. |
FIG. 1 is a right 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, the opposite side being substantially the same as that shown;
FIG. 2 is a front elevational view thereof;
FIG. 3 is a right side elevational view of the right side thereof, the opposite side being a mirror image thereof; and,
FIG. 4 is an enlarged fragmentary front elevational view thereof.
The dark stippled surface shading represents the recessed portion of the tread grooves, having a depth as best shown in FIG. 2; the broken lines defining the tire sidewall are for illustrative purposes only and forms no part of the claimed design.
