The ornamental design for a pneumatictire, as shown and described.
FIG. 1 is a front elevational view of a pneumatic tire showing my new design, it being understood that the tire pattern repeats circumferentially throughout the outer circumference.
FIG. 2 is a perspective view of one side of the pneumatic tire shown in FIG. 1; and,
FIG. 3 is a side elevational view of one side of the pneumatic tire shown in FIG. 1, the opposite side being of identical appearance.
The broken lines in the drawings depict environmental subject matter only and form no part of the claimed design.
