Description

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

FIG. 2 is an enlarged fragmentary front elevation view of the tire tread thereof.

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