What effect does the constant changing pressure in the tires play on longevity.
Any material that is constantly being stretched and then restored to normal is going to take a hit.
The steel belts will eventually suffer fatigue and fail.
Tires with atmospheric gas constantly change pressure as they get warmer/hotter.
The whole selling point of Nitrogen is the lack of pressure change / molecular size and shedding of heat.
Drive your motor home for ten miles on atmospheric gas and then take a laser / infared reading and then drive it for ten miles on 100 % Nitrogen and compare readings.
Propane is an excellent gas for filling tires, it sheds temperature (refrigerant) amazingly well. I have used it when I was in a pinch to inflate tires out in the boonies. One 20 lb bottle (bbq size) will fill about twenty tires because it is a compressible gas. It is in liquid form in the bottle and converts to gas as it is released. The only problem is that it does expand like air,, and of course the false fear that it will explode.
All refrigeration units around the world (except USA) are now filled with propane (hydrocarbon gas). Freon has gone by-by. Sorry DuPont.
Propane has a very small window of opportunity to explode. Too pure,, no boom,, to weak,,no boom. Put your hands on a tire filled with propane vs air and you will be amazed. You can keep your hand on the propane tire but not on the aired up tire.
So there are other options than atmospheric gas.
By the way, I have transported hundreds of Mobile Homes (70's) with propane filled tires, greatly reduced blow outs,, no fire, just large noise.
And NO.......I'm not on drugs...........
