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 throughout the entire outer circumference;
FIG. 2 is a partial end view thereof, shown at an enlarged scale;
FIG. 3 is an end elevation view thereof; and,
FIG. 4 a side elevation view thereof, the opposite side elevation view being identical thereto.
The broken lines along the top and bottom edges of FIG. 2 show the boundaries of the figure and form no part of the claimed design. All other broken lines in the drawings depict environmental subject matter only and form no part of the claimed design.
