Just saw the thread about refilling the Fox stab with nitro.
That made me think, and reminded to ask my dealer on the next trip. (probably tomorrow to just catch up and take the boys to lunch)

Is anyone doing the evac/refill with nitrogen on SD wheels?
This is pretty normal on luxury vehicles (which these really are), and unless you drop/raise to tow regular it is a freaking godsend compared to futzing around with the damn compressor every few weeks.

Thoughts? Real world experience ? Thanks-Jake

 

 

I agree with the statements above, and Im totally on the nitrogen bandwagon. I use it in the racecar, or any other vehicle that hits the track. I actually have the bottle in the shop, hoked up. I use it for quick air, faster and easier than firing up the compressor. Making the assumption you have a water separator on the compressor, I would not bother with nitrogen in SD tires.

 

N2 is an oxygen displacer, so won't break down the rubber like O2 might. It also compresses a little differently than 'air'. That said, I'm sure the differences are negligible and used primarily to loosen your wallet.

My 250 came with N2 as indicated by the green valve stem caps and I've had other vehicles with it but I can't say that I've noticed much difference either way

 

Snake oil!!!!!!!

TLDR: Snake oil

 

tires on my 01 were nitrogen filled once upon a time when the tires were new
first three or four years they NEVER needed refilling due to low pressure

I think it was my chrome plastic faced steel wheels rusting that eventually caused the pressure to begin to go down
when it did I simply started using the gas station air pump
but for 3-4 years it was nice not having to worry about tire pressure

with new tires and new rims I'd spring for it again
(it might have rode a little softer too but that might have been the tires themselves)
tires were 275 60 17 geolanders , now now 265 70 17 wranglers
(with a 2/4 drop they fill the wells completely)

 

I have been doing it for many years. We do it on aircraft tires and the molecules are a little larger so it may not migrate out of the carcass and also has no moisture. Not a whole lot of difference on the change in pressure as the tire heats and cools vs air but it seems to be a little more stable on pressure.

Some are convinced it is a waste of money but you have to decide for yourself.

Uncle only allow nitrogen fill. Some of the AC tires are well over 300lbs! You should see the cages they fill those things in! When they ship a set of gear MLG or NLG for a new AC build they have to lower the pressure to 100 or so lbs. DOT considers them to be hazardous!

 

LOL... picturing Super Duty races... that wouldn't be pretty,So too are bigger tires, wheels with faux bead locks, lifts, airbags, adjustable shocks, levels and stupid wattage stereos then ?
You can't gently rub the tears of fake ceramic angels on the paint every 6 months to maintain the 'warranty', or apply pretend undercoatings at home either...



Oh well. Worth asking, and interesting responses.

 

Similar experience here. Thanks for that.


Exactly. Am also familiar with it from AC.

 

 

A fool and his money are soon parted....

I prefer the free, 78% nitrogen myself...

 

Nitrogen will not leak as easily, as the molecules are larger than the other elements that are in in normal air (the majority of air is nitrogen). From Wikipedia - By volume, dry air contains 78.09% nitrogen, 20.95% oxygen, 0.93% argon, 0.04% carbon dioxide, and small amounts of other gases. Air also contains a variable amount of water vapor, on average around 1% at sea level, and 0.4% over the entire atmosphere

Also nitrogen does not expand as much as air with change in temperatures. This would be the most noticeable reason to use nitrogen oven air, but in a truck the difference is going to be impossible to tell. This is the reason it is used in aircraft tires and in racing.

There may be some validity to filling tires with nitrogen and not air that it does not cause damage to tires and wheels. If there is oxygen present than the wheel can oxidize (or rust if it's steel). And I am aware that ozone will damage rubber, but not sure if oxygen does too. But on the inside of the wheel only as much oxidation can occur as there is freely available oxygen in the air in the wheel. For those of you with baseboard hot water heating the same principal applies for the water in your heating system. Once the dissolved oxygen in the water is used up creating rust on the few iron/steel component in the system no more rusting/oxidation occurs. One of the reasons to not flush you heating system regularly, it would just keep adding more oxygen to allow more rusting.

 

Save your money for something more useful like a taco lunch.

 

My truck came with it. It makes no difference, for all i know the tires could still have regular air in them. I can see the pressue increase and decrease on the tpms depending on the tempature just like air. When i need to fill a tire I'm just going to put air in them.
