New camper coming has nitrogen filled tires

You can buy a disposable inline moisture filter for your air compressor line for less than $3 at Harborfreight or spend a few dollars more and get one that only needs changing occasionally. I do like the bright Green Valve Stem caps though :)

Until it is mandated by the tire manufacturer just apply some forgetaboutit.

OEMs started using N2 because it turned out to be cheaper than a large filter-drier system on their shop air. Unless you are racing on a track with dedicated racing tires, where 1 couple psi has a measurable difference in lap times, it's not necessary. The nitrogen itself isn't even the real benefit (regular is is mostly N2 anyways). It's the lack of moisture that makes N2 tire fills beneficial. Moisture in your tire-air will make tire pressure vary more with heat. And for OEMs, it alleviates moisture concerns that could shorten the life of their tire-pressure-sensors.

Have had it in a few cars and 2 trailers. It is nice in the trailer as the tires hold their pressure and only rarely do you need to add "air" I normally keep adding air and in a few years when I have a moment I may stop and have new nitro done but certainly do not make a big deal about it.

so valve caps are green. Thats about the difference. how much they charge you for that

Lots of kidding about this issue. Many of us wondered the same thing, before realizing, just another gimmick, that has no purpose in RV tires. Just air up, normal air compressor, grin a little, have a good trip!

Nitrogen filled tires! LOL. This is an invention designed by a marketing team rather than an engineering team.

Go to a tire dealer that sells nitrogen. They probably have a $39.00 Harbor Freight air compressor that separates the nitrogen from the air. :B

I would like to know how to check that there really is only N2 in a tire. Maybe there’s a pressure gauge that ignores that pesky oxygen and argon. Not that it really makes any difference than having good old regular air. Now, helium sounds good as it would lighten up the whole trailer.
