Description
FIG. 1 is a side perspective view of a tire tread showing my 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.
