Nitrogen

Did my truck and trailer and I will do the Rhino, the reason being that dry nitrogen remains the same pressure no matter what the temperature. The larger molecules do not pass through the side walls as easily as air, and the dry nitrogen makes the tires last longer, we will see.

not to be a jerk but. i have the same air in my tires for the past 4 years. nitro air is a scam imo.

x2, nitrogen is for shocks..lol

Well when I fill a tire at a desired pressure it stays at the temperature and does not increase when the tires heat up and will not decrease when cold. Nitrogen is a way to maintain handling and grip and I get it free which is even better. Your tires already have 80% nitrogen in them I just remove the 20% of whats left.

shit man, might be somethin to try at 8500' when I ride at the cabin...thx for the research
