Hi folks, does anyone see an issue with using nitrogen with the Pressure Pro system?
Thanks

 Your already using nitrogen,,, air is 87 percent nitrogen. The reason aircraft use it is nitrogen is moisture free so won't freeze at altitude.>>>Dan

Be very careful using Nitrogen if you use your own tanks, tank pressure is unreal.

Since air is about 80% N anyway using it doesn't seem to me to be worth the safety risk and I don't see how it could affect anything in a tire any more than would air.

Nitrogen won't make a bit of difference to your pressure pro system.  It also won't make any difference to your tires, but that's a whole different old wife's tale.

I flew a pressurized aircraft for 35 years and the only nitrogen used on the plane was to pressurize the gear struts. It wasn't because of moisture, but because it was a cheap source for pressurized gas that exceeded the shop air supply pressures.

The tires were filled with good old pressurized air.

Old wive's tale.

Clifford, right now the question is for my truck, it will also be valid for the Scenicruiser!!
Y'all laugh all you want, I have seen the documentation that it saves money over the long haul!
My diesel pickup has got me 90,000 miles on each of the last two sets using nitrogen!
The biggest savings is where you get a nail in a tire that you can't see. With nitrogen, it does not rust from the inside out, therefore the steel belts are not weakened. Which destroys the tire!

I don't know that much about it in tires I do know WalMart has used it for years on all their trucks and trailers tires and they have their own generators at the service terminals that removes the Oxygen making 95 % Nitrogen  

I was told at my local Big O tire shop that if Nitrogen was not used in my tires @ 8 bucks each the tires would not have a warranty which I found out was total bs

   You need to find out how many trucking companies use nitrogen. The nitrogen may not cause nails to rust, but what about the part of the nail that is in contact with the cords that isn't in contact with the nitrogen? How do you know that the truck tires may not have gone 90,000 with old fashioned air in them also? If your set on using it, go for it. I doubt that the pressure pro system would be affected with either source.

The rusty nail/belt story is new, I hadn't heard that one before! The N scam used to be it kept water out of tires and didn't leak as much as air??

chessie said it well, that experience does nothing to prove the worth of N.

It is like when a cold gets better in two weeks is you do nothing or 14 days if you take antibiotics!

What N does is make money for the gas companies.

Nah, nitrogen's over-rated.   I inflate my tires with propane, done it all my life, haven't blowed up yet.   When I needs to cook my roadkill for dinner I just puts an ol' rubber tube 'tween valve stem and BBQ grill, then voila instant tire-side cookin'.   What's wrong with that?

Just kidding . . .

I do agree though that there's very little, if any, incontrovertable scientific proof that 100% nitrogen is better in tires than the 78.09% nitrogen we all breathe.   As with most things, just follow the money.

   Helium might be more beneficial. The blimps use it. If placed in the tires, would probably reduce gross weight of coach by at least several hundred pounds.........

 Jon,, I just retired after 33 years as an IA 36 years as an A/P & 21 years as a corp pilot and Director of maint. for two airlines and one helicopter company,I have owned dozens of aircraft mostly twins. Nitrogen is used in inflatable struts & in place of pure air in air over hydraulic struts to prevent internal corrosion and freezing at altitude, even at that it happens occasionally, and when the gear freezes in the wells things get noisy very shortly after coming over the fence..
 All jet aircraft today use nitrogen in the tire assemblies to help control temps. during high speed ground runs, BUT, I am NOT a proponent of using it in automotive tires.>>>Dan

Really guys there must be some advantage to Nitrogen filled tires I never bought any Cat rubber tire equipment that was not Nitrogen filled at the factory why would they go to the expense ?

I did get tired of buying the stuff but Cat said the tires would have a longer life true or not I don't really know,all I remember is I would have nightmares for a week when I bought a set of tires for a 631 scraper at 32 grand a set lol

the best answer is to do what makes you happy, if you want it, do it, other wise do what the rest of us do.
I mostly only do what makes me happy as long as the DW allows it. Angry

Accept for Clifford, pretty much most of these comments had nothing to do with the question, other than the one one that said it shouldn't be an issue!
I've heard all the snake oil comments before!
I've also seen folks save money using nitrogen!

Utah, I am sure you will agree the primary reason for most uses of N is because it is available and can deliver much greater pressures than shop air. If moisture is a problem (unlikely in the amounts present in typical shop air) then the use of a compressed air dryer will deliver compressed air that is drier than a popcorn fart.

The tire places that try to shove the use of N down our throats are after the money because if N was really important to have in tires they would first pull a vacuum on the tires and then fill with N.

FWIW Robertson Tire does pull a vacuum I watched that he set the bead with air pressure then hooked the pump to pull the small vacuum he forgot about the pump doing something else and the vacuum broke the bead loose I wondered if that was any benefit or not

How can you set the bead with air pressure and draw a vacumn at the same time?

I wasn't clear Gus he set the bead with air when the air was out because the valve stem wasn't in the tire then he pulled the vacuum   

It made no sense to me when he turned the vacuum pump off and disconnected the hose it sucked air back into the tire but he got his 12 bucks a tire  Roll Eyes not from me it was another customer in the shop 1st time I ever saw that done 

They do use vacuum to break down some tires on the high dollar aluminum wheels for cars I have saw that done many of times in Phoenix on high dollar sports car
