Tire tread
FIG. 1 is a perspective view showing our tire tread; 
     FIG. 2 is a front elevational view thereof; 
     FIG. 3 is a side elevational view thereof; 
     FIG. 4 is an enlarged fragmentary front view thereof; and, 
     FIG. 5 is a front elevational view of a tire tread showing a second embodiment of our new design, it being understood that the sides of the second embodiment are substantially the same as the first embodiment shown in FIG. 3 except for the reduced thickness of alternating transverse grooves in the shoulder region thereof. 
     The tread pattern is understood to be repeated throughout the circumference of both embodiments of the tire tread. 
     In the drawings, the broken line showing of the tire sidewall and the solid line defining the peripheral boundary between the tire tread and the sidewall are for illustrative purposes only and form no part of the claimed design.
