I claim, the ornamental design for a tire, as shown and described.
FIG. 1 is a perspective view of a tire, with the back view, top view, and bottom view all being the same images as the front view; and,
FIG. 2 is a front view thereof.
In the drawings, the broken lines defining 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.
