After you took the tread off of these tires you'd be down to 32" tall TOPS for just the shaved casing. Not buying they put 2+" worth of tread cap on it. With a half inch of tread that'd be 1.5" or more of non-tread rubber.If you've seen how thick the tread caps are you might believe it there thick and heavy
I'm thinking their number is as accurate as most tire company's numbers. Half bad math, half fantasy.
