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 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; 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 and inner bead and the peripheral boundary between the tire tread and sidewall are for illustrative purposes only and form no part of the claimed design.
