Description

FIG. 1 is a front perspective view of a tire tread showing our new design, it being understood that the tread pattern repeats uniformly throughout the circumference of the tire tread, the opposite side perspective view being identical thereto; and,

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