inflating tires on rv with nitrogen, good idea?
I'm interested in hearing comments on using nitrogen in tires on my rv, supposed to run cooler and maintain air pressure better. Any comments would be appreciated. Tom

Are we supposed to think air inside the tire is more corrosive than the air outside the tire?
Yes, sort of. AT 30 lbs of tire pressure, compared to 15 lbs of atmospheric pressure, the oxygen concentration is 3X higher. IF the tire is degraded by oxygen, the rate of degradation would be 3X greater.
I agree, sort of. The concentration of oxygen in compressed air is the same. It's the partial pressure that's higher.

In real life this is not much of a factor for the tire's lifespan - treadwear and exposure to sunlight are much more significant.
Agree whole-heartedly. It's the outside environment that determines how long a tire will last. That includes load weight, speed, temperature, braking, scrubbing on turns, UV, heat, ozone, exposure to chemicals, etc., etc.
