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