Aluminum Rims & Nitrogen & tire life ?

Good Morning -



A couple of years ago there was a short discussion on using Nitrogen in the trailer tires with aluminum rims.
I would like to know NOW MANY actually change out the air for Nitrogen ?
My auto shop keeps preaching to me that when one has aluminum rims – the tires need to be filled with Nitrogen. Nitrogen is suppose to reduce the moisture build up inside the mounted tire which in turn will reduce the deterioration of the aluminum rim and it will also extend the life of the tires.



Thus – the questions are - -
NOW MANY actually change out the air for Nitrogen ?
. (Do you know of others that have ?)
What are the costs & who does it ?
When on the road – where do you find Nitrogen when you need to top off the tire ?
Do you have evidence that Nitrogen does extend the life of the trailer tires ?
There are a number of comments that trailer tires last about two years and that the only way to really extend their life is to take the pressure off of them when in storage.
Comments ? ?



Thank You for your time and thoughts.
Have A GReat Day and A Better Weekend.

Atmospheric air is 78% nitrogen. The best you'll get from a tire dealer is about 90% (?) so it's a lot of angst for a 10% upgrade. As long as you check the tires regularly you'll be fine.

Nitrogen molecules are larger so they leak out slower, so the reasoning goes.

I now own a trailer with four tires on the ground. Changing out the tires when they age out is one of those maintenance issues. Would you really NOT spend $500+ on tires to protect a $25,000+ investment? Not me. YMMV

Personally I think the whole nitrogen hoopla and sales is a nefarious plot in order to sell little green valve stem caps.........................

Nitrogen does help keep the tire pressure up longer, but for me it's easier to just check the pressure regularly and use air. I have heard anecdotal stories about it helping it keep the inside of Aluminum wheels from corroding, but honestly the minor difference isn't worth the hassle to me.

My understanding is that if you camp at a NASCAR race you are required to fill your tires with nitrogen.
And drink Bud Light.

I find odd fonts make reading much more difficult, too. Here it is in normal form (plus bullet marks):

I bought tires for my van, which went on alloy wheels, at Costco. They put in whatever passes for nitrogen in their shop, and put on pretty green valve caps. There was no additional charge, and I would not have paid any extra for it.

Since then I have topped up with compressed air from service stations and the portable 12-volt compressor that I carry; I don't know how readily available nitrogen for tires would be, but I assume one would need to find a tire store to get it.

No, and I've never seen any such evidence.

Where did two years come from? The tire industry is pushing a limit of six years, apparently just to sell more tires (since they don't fail at seven years), but only two years is ridiculous, unless you're towing the trailer further each year than most people drive their car.
