New camper coming has nitrogen filled tires

And another marketing scam, pure and simple. Even if they do not charge, they are banking on bringing in more business masked as a huge benefit.

The size of a nitrogen molecule is larger than that of an oxygen molecule by 8 pico meters. A picometer is one trillionth of a meter. That is a pretty small difference.

They use nitrogen in aircraft tires because of the extreme changes in altitudes they experience and the heat generated by landing friction. AS long you you keep your truck and trailer connected to the earth, these "advantages" are not real. But, as in all things, do what you want to do. If it makes you feel better, then that alone is a good thing.

Nitrogen doesn't expand and contract as much as typical air from a compressor due to moisture, so, when your tires get hot, the Nitrogen tire does not expand as much, or have as much of a pressure change.

Horsepucky.

Automotive tires don't get hot enough for moisture to have any impact tire pressure.

You'd have to get the AIR temperature inside the tire above 212F before moisture has an impact. At 212F, you're in deep doodoo already.

Think about it , it would be near impossible to purge a tire on a rim , could not be done even with a vacumn pump .So your empty tire is sitting there 100 per cent full of air , then they add a little nitrogen to bring it up to pressure . And then charge you or not !

Actually at the least shop I worked at we had a Nitrogen machine for filling tires. You filled them with regular air to seat the bead. Then used the machines vacuum function to suck all the air out. It would collapse the tire. Then you filled it with pure Nitrogen. Done properly it works. But for everyday use it’s unnecessary.

There are a hundred different factors that could explain why one tire change with nitrogen lasted longer than one with room air. If it were free, I wouldn't mind them topping off with nitrogen, but I certainly wouldn't request it.

Yep, what he said

Everything you never wanted to know about nitrogen in tires.

OK - I didn't watch this entire video here - but the only point that matters is that he is talking about paying for Nitrogen. I have had it in 3 vehicles and have never paid for Nitrogen. The first time I used it they were going to charge me 5$ for all 4 tires, but after doing it, they didn't charge me. I had him do 2 cars. So, if it is free, why not. There are some benefits.

Actually I think Nitrogen is a benefit. A point to note, just got new tires for my car and Costco uses Nitrogen.

Nitrogen doesn't expand and contract as much as typical air from a compressor due to moisture, so, when your tires get hot, the Nitrogen tire does not expand as much, or have as much of a pressure change. I liked this in my car, which has low profile tires. My first set, which had Nitrogen lasted much longer than my second set of tires that did not have Nitrogen. So, from my experience, it is a benefit.

Finally, your question. No worries, check as normal, if air is needed any air will suffice. You can mix, if you will, there is no difference to the tire. If you have a flat, or have to replace a tire, you don't have to have a nitrogen tire, but I think for the benefits, it is good to keep them the same.

Nitrogen filled tires are for racing and aircraft. No need for them on a rod vehicle.
