I can see major benifints on something like a trailer or tow vehicle. They both typically haul heavy loads and that heats the tires up. Nitrogen is said to keep tire temp down. It will also be nice on trailers because it will hold the air longer on something that isn't used all that often.
I'm not sure about the chorme or alluminum rims bit. Sounds like some of their benifits come from the tires staying properly inflated longer than with regular air. IMO bottom line, keep your tires properly inflated. To do so check them every so often, especially before towning or big trips. If you choose to do that with nitrogen cool, you can always just check more frequently and stick with regulair air.
I would be willing to try it just to see how much longer the tires stayed inflated.
So will nitrogen expand more or less than air as it heats up?
