Description

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

FIG. 2 is a enlarged fragmentary front elevation view of the tread pattern of FIG. 1 showing our new design for the wide tire tread.

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

In the drawings, the dark stippled surface shading represents the recessed portion of the tread grooves, having indeterminate depth.
