Tread of a tire


FIG. 1 is a perspective view of a tread of a tire embodying my new design, it being understood that the tread pattern is repeated uniformly around the circumference of the tread; and,

FIG. 2 is an end view of the tire tread design shown in FIG. 1.

In the drawings, the broken lines defining the tire inner bead and sidewall are for illustrative purposes only and form no part of the claimed design.

The dark stippled surface shading represents the recessed portion of the tread grooves, having a depth as best shown in FIG. 2.
