Heh, apparently you haven't been down to Gilbert lately and you haven't see the pan car guys running. They shave the tire down till about 1/8th of an inch of foam is left, if that. I'm putting brand new tires on the car and making the car ride practically like a monster truck. I've already got a few scratches from breaking the "don't ever run infront of your house" rule. I just couldn't resist.
