Got Tires filled with Nitrogen.

[gratefullife]

I know that it has been said that '04's have a sensitive tire pressure sensor, but between the beep every couple days and the fact that the temp here's been pretty fridgid, I took and had them filled with nitrogen. Read on here before where it's previously been advised, but after having it done, I would completely recommend this for anyone who lives in a cold climate area that has not or is just tired of dealing with low pressure. No sensor light/warning and my tires don't look or feel like I'm riding low.

hmm, that's the first i've heard of this. i think my tires are a bit low right now. what does it cost to use nitrogen? where?

I know Costco fills all of thier tires with nitrogen. I'm sure they can do a fill up, if you are a member.....

Only cost me $5 a tire with about 10min/tire at a local tire/wheel shop. Just make sure they're deflating them and then re-inflating with the nitrogen. Navy uses this in our aircraft. Not only does it deal with temp changes better, but say you were landing your Titan on the deck of a Carrier, not to worrry, the impact is won't be as harsh on the tires with the nitrogen in them.

hah! i dunno about that kinda landing, but i think kartman could relate! lol.

Airliners use it too. I have always heard that nitrogen has a much lower freezing point, and using it will prevent moisture in the tires from freezing at high altitudes.

nitrogen doesnt expand and contract due to tempurature changes nearly as dramatically as normal air does...

We just received our new fire truck with nitrogen in the tires, guess they are trying something new. By the way Im in Florida so not sure of the reason with cooler temp. but it does seem the tires are always low on pressure.

NItrogen is a larger molecule that won't "leak" out as quickly. It's also inert so won't cause oxidation. Additionally, it doesn't have the propensity to carry water along with it. Here's a good link:

Considering 'air' is 70% nitrogen- I see no justification in my spending 25 bucks when I can do it for 25 cents.

On a race car where 1-2psi makes a difference I understand- on a daily driver on source of DRY compressed air will work just as well.

Considering water is 80% oxygen by molecular weight, would you want to breathe that? It's what's in that other 30% of the "air" that does the bad things in this case. I've never done the nitrogen fill either, but wouldn't dismiss it as a viable option after doing a little reading on it.

[RangerNewbie]

'Air' is not a molecule- its a combination of elements that are not chemically bonded.

If you're worried about rusting- how are you protecting the outside of the tire/ wheel? It's exposed to air/ water all the time.


I'm not dismissing the idea totally- I just haven't heard a real compelling argument to convince me it's worthwhile on a street truck.

Isn't it H20 so only 33% is oxygen and 80% and 30% equals 110%. Guess I'm lost somewhere.

here is a link to some info...........

The "sensor" isn't exposed to the outside elements though. That's the part that could be damaged by oxidation, right? I'm just working all this out in my head and typing while doing it, so I'm really not trying to step on anyone's toes. I think it's intriguing though. I've never had a vehicle with a TPMS on it, so really didn't have to worry about what was going on inside the tire before. As for air not being a molecule, I get that, but if 30% of the air I put in my tire were to leak out, I'm thinking that wouldn't be a good thing. I wonder what makes aircraft owners want to use it? Why would it make sense to them? Higher tire cost? It's not heat dissipation. That's a product of the rubber compound the tires themselves are made of.
