Unsafe equiptment. Do you know how many pieces of crap cars we see on the road every day that go un-noticed by the DOT. I wonder if it's raining and you lowside if they would still write you a ticket for Unsafe Equiptment?? "But officer i have pilot powers...."

What a bunch of a-holes. I think him crashing his bike is lesson enough if the tire tread was the cause of the problem.
