air vs nitrogen
Hello all,
I have 225/75/15 10ply tires (2yes old) on our travel trailer.
Is anyone using nitrogen instead of air?
Id would like to hear about your experience etc. if you switched to Nitrogen. How long ago did you switch. What is the process? replace valve stems? I have high pressure ones as I keep 70+ pounds of air in them. Max pressure is 80lbs for these tires.
Pros/Cons
I do not have pressure monitors on my tires(4) would Nitrogen help with tires heating up?
Thanks much for all your replies. This forum is the best.

Total scam for everyday vehicles and trailers. Just regular air is fine. TPMS is always a good idea.

Air is 78% nitrogen, so you don't gain much by using 100% nitrogen. The issue is moisture, which can rust steel and corrode aluminum wheels.
Specifying nitrogen is a waste, and even car manufacturers are moving away from it. What you should do is be careful where you air up your tires. If using your compressor, be vigilant to drain the tank and if using service station air, press the valve down momentarily to see if you get water on your finger. (Service stations often aren't too slick at draining their air tanks.)
Nitrogen is used in race car tires and jets because very small pressure changes make a big difference in race car handling and water will freeze in jet aircraft tires at altitude, which can affect tire balance. Jet tires heat up more than do ours, which can turn water into steam, so yet another reason why those aircraft want dry fills. But for us, just use air and try to keep water out of your air compressor.

Not me. It's impractical.
1. Air is 78% nitrogen already.
2. How can you top off tires with a pump?
3. Yes, nitrogen absorbes moisture, but it's insignificant.
4. Race cars use nitrogen, but they carry large tanks and those tires respond to 1/4 psi difference.
5. Even the tire store that put nitrogen in had a tire full of air to start, they only added nitrogen.

I had a truck once that came with Nitrogen filled tires and love it
Never had to add air in the winter and always maintained their PSI
I'm following this with interest as I think it would make sense in an RV that gets periodically used

If you type nitrogen in the search box near the top right, several threads on Airforums will be found on this topic over the years.
We can play this out again however it isn't new ground.

In my opinion, it isn't a scam if the price to get it is free. Then it is worth the marketing dollars used by the companies to attract my tire business.
Otherwise I breathe easy knowing that proper pressure is far more important that the gas that goes into the tires on my fleet that always travels close to the posted speed limit.

Air is mostly nitrogen.

According to the nitrogen proponents air is saturated water vapor, plus some nitrogen and other stuff.

According to chemists air is 78% nitrogen, the rest is oxygen. Who cares? My tires change maybe 1 psi a month, well within measurement accuracy.

Where are large tanks of nitrogen in race cars? Only tanks we used were smaller than welding oxygen tanks. Certainly no tanks on our racing motorcycles and race cars. Nitrogen takes dif. regulator on tanks. Plus as stated absorbs moisture and then tires run hot gain pressure, when running 150 mph or faster pressure is very important. When we were racing motor cycles using nitrogen always virgin tubes as air contaminates. As stated other posts waste of money to use on road. I also used nitrogen in landing gear [also called struts] of my airplanes, didn't need in tires as very seldom went above 10,000 feet.
