It all sounds like BS to me- if it's the tire we're discussing,
there's no contact with the nitrogen, just the inner tube. The outer
surface of the tire is in air of course, along with exposure to UV
light, salts, etc. The tire is going to lose its rubber well before it
starts to oxidize and crack.

Yeah, I kinda thought that myself which gave me the notion that the fire
thing wiht heavies might be more relevant we run anything up to 300PSI as
well, which might be a factor. I must ask around again.
