Has anyone experimented with Nitrogen in trailer tires? My wife's new car and my new truck both have nitrogen in the tires. They say nitrogen doesn't heat up like air and won't migrate through rubber. My truck has pressure monitors in each wheel. After several hours on the Interstate, there is only one (1) PSI increase in pressure in each tire. I like that characteristic. Should work the same in trailer tires. When I get my boat finished I'm going to try nitrogen. Might work. Might not. Worth a try, though.
