Description

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