The ornamental design for a tread for a tire, as shown and described.
FIG. 1 is a perspective view of a tread for a tire showing our new design;
FIG. 2 is a front elevational view thereof;
FIG. 3 is a side elevational view thereof; and,
FIG. 4 is an enlarged fragmentary plan view of a portion of the tread as
illustrated in FIGS. 1, 2 and 3.
The tread pattern is understood to be repeated uniformly throughout the
circumference of the tread for a tire. The broken line showing of the tire
sidewall in the views of the drawing is for illustrative purposes only and
forms no part of the claimed design.
