Has anyone tried using nitrogen in their tires to control expansion from heat?

NITROGEN

Has anyone tried using nitrogen in their tires to control expansion from heat?

Yes some here have done this ........ but My question is - - is it worth it ... It's certainly more expensive and time consuming to use Nitrogen .......... and IMHO the benefit is sooooooooo small compared to the effort ............. Mike :thumbup:

This.

It works really good........at getting more of your money into the pocket of the tire stores.

Just like with my GMAW welding gas I use a special mix of gases for my tires. With some slight variations it is custom blend of 78% Nitrogen, 20 to 21 % Oxygen, and 1+% other gases. It seems to work well and the cost is only to compress it.:joke::joke::joke:

100% nitrogen not needed for normal folks.

I did....

Well my tire guy did use nitrogen but no charge. I have to say I don't notice any difference but then again can you really say they do put it in :lecturef_smilie:how would the average person know if it was done..?? Seems more of a gimmick next it will be helium to take some wieght off the tires....:roflblack:

I asked the Costco tire guys if they'd fill my Spyder tires with nitrogen and they said they would but I passed on the price which I think was like $20/tire. That's a "you've got to be :cus: me" deal.

Absolutely right. And it can confuse matters.

I bought my C elsewhere (it just came with N, I didn't ask for it) and my local servicing dealer doesn't "DO" nitrogen.......so they did not adjust the pressures when rotating.
And did not reset the monitor either. Grrrrrrr.

I now have taken the green valve stem caps off so I shouldn't have that problem again in the future.

Most of what advantage there IS comes from the lack of water vapor in the tires. You can get that with a dryer attachment for your air compressor.
But it REALLY is not needed.

 

[ofdave]

what about the cool green valve caps?
isn't that a good enough reason?

This is one of the greatest scams foisted on gullible people ever. Before paying for nitrogen in any vehicle tire, ask the salesperson what the real benefits are for the cost. You will be presented with a long list of snake oil claims. ALL passenger aircraft use 100% nitrogen in their tires for two valid reasons. 1- nitrogen will not support combustion. 2- nitrogen will not hold moisture which can condense into water, freeze at altitude, and cause balance problems upon landing. These reasons have absolutely no bearing on road vehicles. Save your money for that bridge that is for sale in New York.

The idea behind using nitrogen is to reduce pressure rise/fall due to temp changes. When I used it before it became too much of a hassle, I did like the fact that the pressures remained much more constant from cold setting to after the tires heated up. Normally in the 1-2psi range vs 4-5 on O2..... It also reduces the pressure drop over time as the nitrogen molecules are larger than oxygen, and don't "bleed" as easily so you aren't having to add as often. But as stated, it can become a hassle finding a shop that does it and having to go there vs doing it yourself....

Just want to be able to run my Sears compressor. Life can be difficult enough.

Makes you wonder if the Costco guys were putting it in their pockets! My local Costco uses nitrogen as part of the mount and balance package for new tires.

Here's the only statement I found on the Michelin website regarding nitrogen in tires.

Inflating tires with nitrogen does not exempt you from having to check tire pressure routinely.

Cooper Tires identifies no benefits to using nitrogen. Doesn't provide protection against damage by under inflation, over inflation, punctures, etc.

Only reference to nitrogen on Yokohama web site are a couple of non-informative customer reviews.

Use nitrogen diluted 22% with oxygen + misc trace gases. It's free!!!

 

[SPECTACUALR SPIDERMAN]

nitrogen is a dry, inert gas that does not contain moisture. yes it is better especially if you have chrome wheels or tpms.

 

[Easy Rider]

2- nitrogen will not hold moisture .

You have the right idea but that detail is wrong.

It will "hold" just as much moisture as air, once the moisture gets in there.

The process of separating it out from air produces LIQUID nitrogen and removes all the water.

 

[Easy Rider]

It also reduces the pressure drop over time as the nitrogen molecules are larger than oxygen, and don't "bleed" as easily

THAT is one of the snake-oil claims.
Total bunk.

 

[Easy Rider]

nitrogen is a dry, inert gas that does not contain moisture.

No it isn't. Once it is back to a gas, it will "contain" just as much moisture as would air in the same circumstances.

Regular air is almost 80% nitrogen so you are adding only another 20% by going full nitro.

And the moisture content is important only if you have steel rims. Alloy rims do not rust so water vapor is not important (at the levels you would find in a tire).

The reason NASCAR uses nitrogen is because it is more volume stable as the tire heats up from use. You would not notice this difference in your passenger car tires.

aluminum doesn't rust, it corrodes. the moisture will rust chrome plated aluminum rims and can cause galvanic fusing of the valve
core and a valve pin.

First of all, the seller would have to purge all air from your tires after mounting them. If they simply bring them to pressure with nitrogen, what happened to all that nasty oxygen that was already in them? Second, for the folks that are correct saying that the molecules are bigger and therefore you don't have to add to them as often, are you adding more 100% nitrogen or regular air? Unless you have a tank of 100% nitrogen you are reintroducing that nasty old oxygen right back into your wheels. I've had quite a few vehicles over the years and have never had a wheel rust through from the inside due to oxygen. And technically, yes, nitrogen can hold moisture, but it is dry when bottled and sold to the end user shops. In aviation, a good mechanic will purge the fill hose with nitrogen before even hooking it up to the wheel to purge out oxygen and moisture so as not to add them to the tire. Ask the guys at Costco about that.
