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 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 thereto;
FIG. 4 is an enlarged fragmentary front elevational view thereof;
FIG. 5 is a front elevational view of a modified embodiment, the side elevational view of which is the same as FIG. 3; and,
FIG. 6 is an enlarged fragmentary front elevational view of FIG. 5.
The dark stippled surface shading represents the recessed portion of the tread grooves, having a depth as best shown in FIGS. 2 and 6; the broken lines defining a portion of the tire sidewall are for illustrative purposes only and form no part of the claimed design.
