The ornamental design for a tread portion of an automobile tire, as shown and described.
|
FIG. 1 is a front view of a tread portion of an automobile tire according to my new design;
FIG. 2 is a perspective view thereof;
FIG. 3 is a rear view thereof;
FIG. 4 is a left side view thereof;
FIG. 5 is a right side view thereof;
FIG. 6 is a fragmentary enlarged view thereof; and,
FIG. 7 is a cross-sectional view taken along line 7-7 in FIG. 6.
In the drawings, the portions of the tire and tread shown by broken lines are not claimed, and thus these portions form no part of the claimed design.
