Nitrogen Tires

[JUSTAROBB]

Hey all, my 2010 sierra has nitrogen in the tires. I have recently gone for a free top up as they were low. 45 mins later at the dealership, i'm on my way, WTF, do I need/want nitrogen? Do i have to remove it completely to use air, or can i just add air to the tires and have a mixture? I mean a 45 min. proceedure to put 5 psi in my tires. I think it is just a way to get you back to the dealership so they can go over your truck, to "find something" that you never knew existed, but needs to be changed. sorry pissed and rambling now. Any suggestions would be appreciated.

It really doesn't make that big of a difference. EXAMPLE: I hit something on the road and it removed a pretty good chunk of rubber out of the sidewall, so I had to replace the tire. The only shop in town that had the size I needed didn't have nitrogen. The next day I'm pulling the trailer, 95+ degree day so pressure changes are going to show (heavy load, high temps). Nitrogen tires went up 4 psi, air tire went up by 5 psi according to the TPMS. Since tires have been rotated, I couldn't tell you which tire is which any more. If you need a fill, put in air, no need to drain nitrogen out. By the why, air is 78% nitorgen anyway.

Nitrogen is used in aircraft tires and the spars of some of the fancier helicopters as a leak detector because there is little to no moisture and the pressure changes that occur with altitude difference are nowhere as dramatic as with regular air. On a vehicle - IMHO - it's a ploy to get you to spend money. They charge for this "mystery" gas. You will be fine with just topping off at the local service station.

THX!!!!! Air it is

Bob, thx for that confirmation!!

hey everyone my wife has a 07 mazda cx-7. its pretty damn fast with it being a crossover thats turbo. but the biggest complain is the damn tire light. especialy when winter hits and throughout winter. the tires pressure up and down light on all the time. so i spent about 20 some bucks for a local tire shop for nitrogen. all i can say is wow. 2 years not one tire light since except for her having a screw in her tire. so to me i can see a big difference

The air we breath is already over 78% nitrogen - so 99% nitro tires are really more of a zero-value add-on for consumers (meaning, go ahead and spend the $20 - it's your money). The CS report findings confirm this fact.

^^^^Exactly.

If you use nitrogen in the future be sure to buy tires that allow you to use it. Some tire rubber compounds can not use nitrogen because it will degrade the tire faster.

 

FWIW I heard this from a number of tire manufacturers, whether there is a lot of validity to it i have no idea.

I don't know how that can be true when air is already 78% nitrogen. Sounds like a old wives tale that is being propagated by shops that don't use nitrogen.

I would hazard a guess that you live in a high humidity area, or the tires were mounted and filled in a high humidity area. It is the moisture that creates the biggest change in pressures. Perhaps the Mazda system is too sensitive or has too small a window for tire pressures to be in?

Regardless, the Nitrogen STILL changes with temperature... albeit more "accurately" than air. Everyone should still be checking their tire pressures seasonally since a swing of 60 degrees for the average daily temp WILL change the tire pressures.

 

His tire pressure light probably isn't coming on because all 4 tires are losing the "same" amount of pressure... depends on how the system works. Some systems read each tire individually and other systems compare the pressure in the other tires and looks for one that is different.

 

In any case, Nitrogen in automotive tires is a waste of money IMO. There's really no "true" benefit if you're maintaining your vehicles properly (and that includes checking the winter/summer tire pressures).

Cosco does it for free, that would be the only time I'd get "pure" nitrogen in my tires.

My service station features a special 78% nitrogen formulation which they supply free to a few of their most loyal customers. I find it works great under heavy loads.
