HOOOHA

64PSI

That would explode ANY regular tire. PSI is Pound per square inch
FORCE and that doesn't change with the desnity of the gas. In fact that force is what blows the tire even when it's water!!!!

and Helium is NOT flammable that hydrogen. Helium is a noble gas which WILL NOT react almosr ever!

Even nitrogen is hardly activated! that is what 4/5 of the AIR consist of. Yes 4/5 of the "Air" is Nitrogen!
