Nitro filled Tires

As a tire dealer I can add a little more perspective that the general public may not be aware of and have posted this several times. Whether you are are using 78% nitrogen (regular air) or nitrogen that has been filtered thru a membrane to achieve usually 90-92% nitrogen in the tire..... how do you know what the actual % is. Do you have any way to analyze what the % is outside a laboratory environment?


Couldn't someone just use a regular air compressor to put 78% nitrogen in your tire and "technically" say it's nitrogen filled since it is by majority. Is there a law, judge, or jury to say different?


I am good friends with the owner of a local tire supply business (our sons grew up together). He has laughingly told me several times of a few local tire stores and car dealerships that buy the green valve caps (a sign that a tire is supposedly been filled by a nitrogen compressor) from him, that he knows do not have the nitrogen compressors and they just use regular air compressors. These tire stores charge $5 per tire for the 78% nitrogen and a green plastic cap. Their customers are none the wiser and never will be while these dealers are laughing all the way to the bank.

I am surprised someone hasn't said in any of the previous discussions on nitrogen filled tires that since nitrogen molecules are larger than oxygen molecules the tires will need less pressure to fill them.


Whoops, shame on me!

I probably shouldn't have said that as some "idiot" will take it as gospel because as we all know, if it's on the internet it has to be true.


Disclaimer: I'm not intending anything derogatory towards any member of this forum, I'm just saying if you use your favorite search engine for info on nitrogen filled tires these discussions will be in the results and anyone can read them without being a member.

Don't worry, more than just "some" already have.

Considerfing outside air is 87% nitrogen....just pump it in...

All the smoke aside there is an actual physical reason for filling the tires with nitro, leakage. Nitro is a larger composition than oxygen hence less leakage thru the rubber compound.

I think your fingers were a bit dyslexic.

I made sure I got the #1 nitrogen.
Costs a lot more but makes me sleep a lot better at night.

I dunno, I think:

N2=28 g/mol

O2=32 g/mol

so if a tire leaks because of small molecules leaking out of it then eventually all the small molecules leak out and we are left with nothing but nitrogen?

on the scientific side oxidation affects everything that is exposed to oxygen, so oxygen causing oxidation on just about everything is probably the real reasoning behind using nitrogen and an inflation medium, remember vacuum packaging removes air.. preserves things because of that pesky gas oxygen, which contributes to oxidation

I only worry about oxidation for important stuff. Like making beer!

good point,. but oxygen is among the most toxic atoms in the universe, exposure to oxygen has a 100% mortality rate lol

After having one of the "China Bombs" go off on my 2017 Forest River VIBE 268RKS, I purchased five Goodyear Endurance STs Load Range E (four to replace the tires on the trailer and one to replace the blown tire I had put in place of the spare).

I originally had set the pressures at 5 psi less than the maximum pressure, thinking I would get greater weight support from the tires. The ride was a bit stiff. Then I started wondering exactly what the "proper" inflation pressure would be. After many weeks of research, I finally found the answer on the Goodyear site.

The proper inflation pressure for the new tires should be what the RV manufacturer calls out for your RV. The tires will provide all required support in the load range for the RV at the recommended pressure setting as long as it does not exceed the maximum rating of the tire.

i took mine off in less than 1000 miles, it bothered me that my 9985 GVWR TT had 10 ply tires from the factory and one of my customers 8k dry weight had 8 ply tires on it when he elected to replace them after his first trip out, mine recommended 80 psi and his was recommended to have 65 psi, im sure he was over 10k on GVWR

im not sure what these manufacturers are thinking on these

I always use "Nitrogen Lite" it's only 78% Nitrogen and less filling than regular Nitrogen, but is still as tasteless and odorless as regular Nitrogen.

My dad had one of those spark plug pumps too. We thought we were really moving up in the camping world😃

I hope you have a thick skin and are not easily discouraged. Honestly, I have to admit, until you asked the question I had no idea. Keep asking questions. I have learned so much since I joined the forum.

Nitrogen in tires is a scam. From 2015:

If we decide to stick with Nitrogen, is it best to go with 5% or 10% ethanol content?
