Nitrogen Filled Tires

[davidbrady]

I'd save my money Chuck. The aircraft industry uses nitrogen mostly because it's more inert than O2 so it tends not to corrode tire rubber or magnesium rims. The fact that the larger N2 molecule (larger than O2 and dihydrogen oxide) permeates rubber more slowly is an added advantage. Every tire I ever had off my bus wheels was bone dry inside telling me that the 02 and H2O readily leach thru the rubber carcass leaving behind almost pure N2, so in essence you get nitrogen pressurized tires for free.

Ron Rueckwald ran a study of Nitrogen in his LXi tires and IIRC he didn't notice any appreciable difference in ride or in pressure stabilization.
