The ornamental design for a tire, as shown and described.
FIG. 1 is a front view of a tire showing our new design; and,
FIG. 2 is a partial, enlarged view thereof.
The drawings include shadows and reflections which indicate contour, not surface ornamentation.
The broken lines illustrate boundaries which form no part of the claimed design. In FIG. 1, the blurred portions in the drawing form no part of the claimed design.
