Half a penny???? A penny is 3/4 of an inch. Half of that would be .375 of an inch or 12/32, which is more than most tires have brand new.
I think most say up to Lincoln's head when the head is pointed down, which would be about 3.5/32, which might pretty close for passing.
I think those in the pic would pass if the inspector has had a good day.
Aren't there wear bars around the tread??
