Pneumatic tire tread and buttress

Description

FIG. 1 is a perspective view of a pneumatic tire tread and buttress showing our new design;

FIG. 2 is a front elevational view thereof;

FIG. 3 is a fragmentary side elevational view thereof, the opposite side being substantially a mirror image of that shown;

FIG. 4 is a perspective view of a pneumatic tire tread and buttress showing a second embodiment of our new design;

FIG. 5 is a front elevational view of the embodiment of FIG. 4;

FIG. 6 is a side elevational view of the embodiment of FIG. 4, the opposite side being substantially a mirror image thereof; and,

FIG. 7 is a front elevational view of a pneumatic tire tread and buttress showing a third embodiment of our new design which differs from the second embodiment only in the omission of the circumferential row of blocks adjacent to the left shoulder ribs.

The pattern is understood to be repeated uniformly throughout the circumference of all three embodiments of the pneumatic tire tread and buttress.

The broken line showing of the tire sidewall in all seven views of the drawings is for illustrative purposes only and forms no part of the claimed design.
