The more H2 you put in, the lighter it becomes! Put 100psi H2 in those tires and you would have to put a brick on your roof to hold the car down. Blowouts would be reminiscent of the Hindenburg.

I have wondered what the weight reduction would be if helium was used instead of nitrogen; unsprung weight being more of a concern than sprung weight (unsprung being weight carried below the suspension). I imagined it was such a little difference that it wouldn't concern anyone, but perhaps in racing where every advantage is utilized...
