FIG. 1 is a perspective view of a center tread for a tire showing our new design, it being understood that the pattern repeats uniformly throughout the circumference of the tread;
FIG. 2 is a front elevational view thereof;
FIG. 3 is a right side elevational view thereof; the opposite side elevational view being identical thereto; and,
FIG. 4 is an enlarged fragmentary front elevational view thereof.
In the drawings, the broken lines showing of the shoulder tread, sidewall, inner bead and the peripheral boundary between the circumferential center treads and the shoulder tread and between the circumferential tread blocks in FIGS. 1 through 4 depict environmental subject matter and form no part of the claimed design.
