The ornamental design for a tire tread of a vehicletire, as shown and described.
FIG. 1 is a perspective view of the tire tread of a vehicle tire, showing my new design;
FIG. 2 is a front elevational view displaying a larger section of the repeating tread pattern thereof;
FIG. 3 is an enlarged partial front view thereof;
FIG. 4 is a left side elevational view thereof; and,
FIG. 5 is a right side elevational view thereof.
It is understood that the claimed tire tread pattern is intended to be applied to the entire surface of the tire, as indicated schematically in solid lines in the drawings. In the drawings, the broken lines defining the sidewall, and inner bead depict environmental subject matter that forms no part of the claimed design. The dash-dot-dashed lines form the boundary of the claimed design on the unclaimed sidewall of the tire.
