Pneumatic tire tread and buttress

Description

FIG. 1 is a first perspective view of a pneumatic tire tread and buttress showing my new design, it being understood that the pattern is repeated throughout the circumference of the tread and buttress, the opposite side being substantially the same as that shown;

FIG. 2 is a front elevational view thereof; and,

FIG. 3 is an enlarged fragmentary front elevational view thereof.

The broken line showing of environmental structure in FIG. 1 of the drawing is for illustrative purposes only and forms no part of the claimed design.
