Hello,

I'm wondering is anyone has thought about things like filling tires with FOAM rather than with air? At the very least, this would reduce/eliminate the need to ever re-inflate, and you could not get a flat; by definition. And, I guessing that this would minimize the rolling resistance, too.

[Edit: I want this to minimize rolling resistance with conventional tires and steel wheels. I think that new car designs should incorporate rigid wheels and tires -- and have all the suspension function in the suspension and use the hydraulics/pneumatic of the shocks and springs to charge the battery.]

What do you think? Do you want to try it? What sort of foam would you use, and how would you get it all around the tire?

Please post your thoughts.
