I claim the ornamental design for a tire, as shown and described.
FIG. 1 is a front view of my new design comprising a tire; and,
FIG. 2 is a side view of the tire shown in FIG. 1.
In the drawings, the broken lines defining tread groove elements, the sidewall, inner bead and the peripheral boundary between the claimed tire tread and the unclaimed sidewall depict environmental subject matter that forms no part of the claimed design.
