The ornamental design for a tire, as shown and described.
FIG. 1 is a perspective view of a tire showing my new design;
FIG. 2 is a front elevational view thereof; and,
FIG. 3 is a left side 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 portions of a tire that form no part of the claim.
