FIG. 2 is a front elevational view thereof;
FIG. 3 is an enlarged partial front view thereof;
FIG. 4 is a right side elevational view thereof; and,

The dash-dot lines showing the boundaries of the illustrated detail form no part of the claimed design.

While only portions of the tread design are shown, it should be understood that the tread covers the tire circumferentially in its entirety.
