Description

FIG. 1 is a perspective view of a tire tread showing our new tire tread design, it being understood that the tread pattern of the tire tread is repeated over the outer circumference and shoulder of the tire, the opposite side being the same as that illustrated; and,

FIG. 2 is an enlarged fragmentary front elevation view of our new tire tread design thereof.

In the drawings, the dark stippled surface shading represents the recessed portion of the tread grooves, having a depth as best shown along the right edge of FIG. 1.

The broken line disclosure of a tire sidewall and inner bead is for illustrative purposes only and forms no part of the claimed design.
