the oxidation between a rubber compound in nitrogen and of a rubber compound in your daily fill station air. ( or your own compressed air for that matter) is not going to come into play for at least several years.
more like about thirty or forty years so.take how you will.
once more I have worked in the rubber and urethane industry from about the time I was fourteen until I was like 31 so that's a few years of experience.
in my "take it as you want" opinion it isn't going to give an advantage or disadvantage for that matter.(in a wheeling situation) All the above metioned reasons are most likely valid but wouldn't come into play for several years and certainly the tires would be worn out before they are ever corroded from the inside out. ultraviolet rays are the biggest killers of tire carcases. (don't believe me) go look in a junk yard at tires that haven't had air in them for years yet "wow" they are still dry rotted.
and as for heating them up for better traction thats a surface contact heat caused by friction. and will heat the carcase and tire from the outside in not the other way around. now the air compared to nitrogen would hold the heat longer and adversly change your air pressure very slightly. and I mean very slightly in a tire that has sometimes as little as 5- 12 lbs in the situations we are talking about where a half pound to a pound variation isn't going to matter. since the next creek crossing will adversly effect the pressure in the oposite direction.
one of the biggest inner liner killers isn't the air they contain, but the amount of oil that got transferred to the air through the compression and filtration cycle. if anything will kill your tires it's going to be the oil your compressor allowed by.
my two informed cents
