Description

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 a mirror image of that shown;

FIG. 2 is a front elevational view thereof;

FIG. 3 is a side elevational view of the right side thereof;

FIG. 4 is a side elevational view of the left side thereof; and,

FIG. 5 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 a portion of the tire sidewall and the peripheral boundary between the tire tread and sidewall are for illustrative purposes only and form no part of the claimed design.
