Nitrogen filled tires

[lwbones]

Reciently purchased a Wildcat 31t with tires filled with nitorgen gas. I have not heard of this use in rv applications. Would be interested in experiences with this type of tire fill. lwbones

I think this has been discussed here before in great length if you do a search for nitrogen. The sales brochures like to point out that because they use nitrogen in Nascar and on the space shuttle that it is some big advantage in RV and car tires too. Their advertising is compelling but after all they are trying to sell people a product. Since RVs do not go into outer space or run at speeds of over 200mph, and because we replace our tires usually before the tread is gone (or you should as you shouldn't be running on tires older than 7 years old anyway) nitrogen really makes no difference. Plain old compressed air has been working for decades just fine and can be found everywhere and is usually free. I would not pay for the inconvenience of using nitrogen.

I agree with NW Jeeper. If your RV came with a nitrogen fill, then that is great. But if you are thinking about paying to get that, then save your money.

The air coming from an air compressor is 80% nitrogen. Most nitrogen fills can give you at most 95% nitrogen, and that is best case conditions. So that extra 15% is really going to make a difference?? And I don't belief in all of the hoopla over the benefits of nitrogen over plain old air. If you gotta pay for it, save your money.

Pretty much becoming widely known that this is a scam cloaked loosely by a few scientific facts.

Bottom Line - Check your tire pressure regularly.
