One of the main causes of rubber deterioration is ozone. The normal range at ground level is 10-15 parts per billion. It is the main cause of rubber cracking. If the dry nitrogen has no ozone it is better than regular air, but how do you protect the outside of the tire. The size of the nitrogen molecule does slow pressure loss and nitrogen does not change volume as much with temperature change as some other gases.
So ozone plus sunlight deteriorate rubber on the outside. I read over the PM article rather quickly, but ozone was not mentioned. I imagine the longivity of race car tires is too short to worry about ozone. The outside tire coatings usually contain some antioxidant which would slow cracking. Are there any treatments that have an antioxidant for the inside of the tire?
There are tire covers, but I don't know if they slow air movement at the tire surface but good ones stop sunlight deterioration. At the current price of tractor tires I wonder if it would be worth the time and effort to cover rear tires when there are periods of time say greater than a month where a tractor is not being used. I am going to look up any research to see if anyone has done any such study.
I would probably have to look it up on Proxmire's golden fleece awards.
