The ornamental design for a tire tread for a vehicletire, as shown and described.
FIG. 1 is a front elevational view of a tire tread for a vehicle tire, showing my new design;
FIG. 2 is an enlarged partial front view thereof;
FIG. 3 is a side perspective view thereof; and,
FIG. 4 is a right side elevational view thereof.
The vehicle tire pattern is repeated uniformly around the circumference of the structure. The dash-dot lines showing the boundaries of the illustrated detail and the broken lines depicting the sidewall of the tire do not form part of the claim.
