Rob, does USAC have a range that they deem legal as far as the durometer readings? I've heard of instances were tires are doped with various chemicals and I was curious if those particular tires would duro'd softer then normal.

I know go-kart organizations have fought for years on spec tires, tire additives, durometer tests and even having "sniffers" that can tell if a tire has an additive on it or in it.
