The ornamental design for a tire tread, as shown and described. |
FIG. 1 is a front elevational view of a tire tread showing our new design, it being understood that the tread pattern repeated throughout the circumference of the tire tread, the opposite side being the same as that shown;
FIG. 2 is an enlarged fragmentary front elevational view of FIG. 1;
FIG. 3 is a front elevational view of a second embodiment thereof, it being understood that the tread pattern is a mirror image of that disclosed in FIGS. 1-2 and is repeated throughout the circumference of the tire tread; and,
FIG. 4 is an enlarged fragmentary front elevational view of FIG. 3.
The dark stippled surface shading represents the recessed portion of the tread grooves, having a depth as best shown in FIG. 1; the broken lines defining the tire sidewall are for illustrative purposes only and form no part of the claimed design.
