The ornamental design for a pneumatictire, as shown and described.
FIG. 1 is a perspective view of a pneumatic tire showing my new design, it being understood that the tread pattern repeats circumferentially about the outer circumference and shoulder of the tire.
FIG. 2 is a front elevational view, the rear elevational view being a mirror image thereof; and,
FIG. 3 is a left side elevational view, the right side elevational view being a mirror image thereof.
In the drawings, the broken lines defining the inner bead depict environmental subject matter that forms no part of the claimed design.
