Nitrogen in tires

[old timer]

Looking at purchasing new tires for camper, bell tire employee said they don't have nitrogen, is nitrogen in tires worth passing and looking elsewhere? How do I know for shur if they are filled with nitrogen anyway?
Price out the door was 300.00 and tax for 4, 14 inch load range c.

Nitrogen filling tires is a scam. Pass on it.

Nitrogen filled tires have a green cap on the stem. It's used allot in race cars. Probably a scam as stated above.

You can buy a canister, or! Modify an OO generator and produce your own. Costco has a service offering, just not sure they will do a MH.

Should not be a game changer! Every time you bring the tire up to pressure, you will be putting OO in the tires.

Thanks, makes sense

Nitrogen has different expansion/contraction characteristics as compared to air. You won't see pressure swings in nitrogen filled tires like you will in
"normal" air filled tires. The problem I have always had with nitrogen filled tires, is that you have to find a tire shop that offers nitrogen service when you do have a low tire.

In my opinion it is nice to have dry inert gas in tires, when offered that would be my preference.

That said, clean and dry is critical in my thinking.

Normal atmosphere is about 78% nitrogen.

According to the all knowing rectangle of knowledge…..

I agree, clean dry air is the only must have. I would challenge anyone to have one tire filled with “air” and another with nitrogen and see any significant difference to the temp and pressure of the tires at operating temperature

Here is a did you know!

Did you know the inner surface of the tires carcass has a different rubber compound?

This is necessary to make a tubeless tire. The compound allows a membrane builtin to the body of the tires so the pressure is maintained.

Have you wondered why as a tire gets older you have to adjust pressure more often?

Yes because that membrane starts to oxidize!!! Put simply, no oxygen, no oxidization!!!

I have no problem with handling on my vehicles,as long as my tires are equally inflated! However if one tire is at a different pressure The vehicle seems less stable! The only answer to that problem is to observe a table on unlevel ground!!!

Because I love you-all I won't challenge you to fill only one tire with nitrogen,to see how it goes!

I am looking for an old oxygen concentrator to modify as a nitrogen concentrator. You can do whatever you feel comfortable with! Just as I will!!! In the meantime, the Costco service seems reasonable!!!

The prior owner of our setup was a pilot - he carried a nitrogen cylinder in the cargo area in the trailer strapped to the wall. Used the nitrogen on the trailer tires but not in the coach tires.
Over time (after rotating and remounting tires and no longer using nitrogen in trailer tires) we noticed that the trailer tire pressures have a much higher fluctuation in pressures than they used to when going to higher elevations and changing temps.
Been considering going back to nitrogen again.

The price out the door sounds reasonable, so I will go with the no nitrogen, this looks like a 50/50 answer on the air or nitrogen

Our tires came filled with nitrogen (9/22). In March 2023, I topped them with air with my compressor as they were down 10 PSI or so. I occasionally topped them up last year before weekend uses.

When I checked the tires before moving the trailer to storage a few weeks ago (we moved), they were all pretty close to 60 PSI, where they’re supposed to be.

I don’t think it’s worth worry about what’s in the tires. Just check the tire pressure often.

If you think it is a scam, go ask an A&P, that an aircraft mechanic what they put in air liners tires!
Going from 100+ temps to well below zero numerous times a day does to tire pressure?
Nothing because they are filled with nitrogen!! Duh!!

If you’re doing that kind of temperature extremes in your RV, go for it.

Only one I know that likes extremes is Neal! And that ain't several times a day!

Still freezing to warm tires, well maybe hot (standard TPMS) reading,create conditions where nitrogen would be beneficial.

 

[RVThereYet]

The point is that if an aircraft can do it with that wide spread temp fluctuation then an RV changing temp 50-60 degrees is nothing. It can help that swing in temp but is it worth it? You know what they say about opinions, like (deleted), everyone has one!!

Maybe I need to be filled with nitrogen, I go from cool to hot all the time driving!
But seriously thanks for the reply, but the tire price sounds pretty good,
It does say on the original tires they are nitrogen filled, hard to believe the factory will take extra measures to fill the tires with nitrogen, and not use the same diligence on the trailers.

 

[Joe Hogan]

Being mobile is in my opinion the limiting factor for maintaining Nitrogen in tires. Having a Nitrogen generator or tank at the shop is certainly desirable to maintain tire inflation.
The largest tire pressure adjustments when on the road we have seen is when there are large altitude and/or temperature changes.

Quite a different environment than the typical RV or auto tire experiences. For typical street tire use it’s a scam.

Been filling my tires with compressed air for 25 years, but what do I know
