Everybody knows how much we like mobile service so we were intrigued when Jo saw this setup driving around the KOA in Albuquerque so Bob flagged him down.
There are many benefits of nitrogen filled tires. Nitrogen reduces the loss of tire pressure due to leakage through the rubber of the tires by about 1/3 means less times you have to fill up the tires. Nitrogen is a dry gas air so there will be less corrosion of the tire's steel components like the sidewall reinforcements and belts. There also will be more consistent pressure as the tires heat up during towing.
Now for the rest of the story. Nitrogen is still a gas and is affected by changes in temperature, about 1 psi for for 10 degrees F. Nitrogen isn't always readily available, although it is getting better. Getnitrogen.org is a website where you can check. The list includes surprisingly Costco Tire Centers and mostly car/truck dealerships. The website does list if the place is truck friendly. Getting the RV in tow to some of these places, plus the lack of availability is why we bought the UltimateAir tank and had it filled with nitrogen. If necessary you can always add regular compressed air to you nitrogen filled tires because proper pressure is more important than the purity of the nitrogen.
Truth be told if the tires did not come with nitrogen we doubt we would have converted to nitrogen. Now that we have it we have decided to keep the nitrogen filled if possible.
Till next time,
