FIG. 1 is a perspective view of a tire tread showing our new design, it being understood that the tread pattern repeats throughout the outer surface and shoulder circumference of the tire tread; and,

FIG. 2 is a enlarged fragmentary front elevation view of the tread pattern 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.

In the drawings, the dark stippled surface shading represents the recessed portion of the tread grooves, having a depth as best shown along the central right edge of FIG. 1.

the grant prints no section headings; every part label below is ours, taken from that part's own first words
