FIG. 4 is a right side view thereof, the left side view being identical;
FIG. 5 is a fragmentary enlarged front view of the portion 5 framed in FIG. 2;
FIG. 6 is a fragmentary enlarged front view of the portion 6 framed in FIG. 5; and,

Broken lines show environmental portions of a tire sidewall that are not being claimed, and form no part of the claimed design. The dash-dot-dash broken lines are used to show the boundary between unclaimed and claimed subject matter, and thus form no part of the claimed design.
