Ultrafinder Posted March 20, 2007 Share Posted March 20, 2007 My mom leases a car from Toyota and under her contract tires are covered. They hit her up for mounting, balancing and alignment. thats fine, I understand. But they also charged her $40 for a nitro fill in the tires. I flipped out so-to-speak. They guy actually said its gauranteed air pressure for the life of the tires because, reg. air has moisture in it and will seap out. also said the nitrogen doesnt heat up like air? therefore wont expand and contract. Is this some crap from a dealer? Link to comment Share on other sites More sharing options...
patzx300 Posted March 20, 2007 Share Posted March 20, 2007 We do Nitrogen in all of our tires at my dealership. The whole air pressure for the life of the tire is not entirely true. Tire pressure will remain more constant which means overall more consistent tire size which will lead to longer tire life. http://www.nitrofill.com/ Link to comment Share on other sites More sharing options...
94extreme Posted March 20, 2007 Share Posted March 20, 2007 nitro molecules are of a different structure and don't pass through the rubber like O2 but i feel that to be a total luxury.. if you do a bunch of air-downs then i surely don't see a point. in your mom's case.. well, that boils down to money.. if she can't afford it then she shouldn't be doing it.

88pathoffroad Posted March 20, 2007 Share Posted March 20, 2007 I think it's a crock of crap to do that and then try to charge people for it afterwards. Definitely not worth $40. For $40 you can buy enough nitrogen to fill 100 tires. Link to comment Share on other sites More sharing options...
meangreenmachine Posted March 20, 2007 Share Posted March 20, 2007 But you have to pay for the machine sumhow. I agree that it is kind of pricey but this is the trend that tires are taking, and in the not so distance future all new cars will be required to be filled with nitrogen from the factory. Nitrogen doesn't leak like oxygen because it has larger molecules and it is a more stable gas that is not as affected by temperature (doesn't expand and contract like oxygen).

Precise1 Posted March 21, 2007 Share Posted March 21, 2007 I'm with 88. I'll run air, please. I'm handy enough to check my tire pressure every 3 months or so and adjust as necessary... This is just something for people who have no ability/desire to pay the slightest attention to the maintainance of their vehicle. To each, their own, but I have no use for it. We have a nitrogen 'generator' at work, they are not that expensive. http://eagleequip.com/page/EE/PROD/NGEN/NA4-60 Charging $40 for a fill up, if you did 1 car every day for a year, would pay for the unit and $10k in profit. CRAP, I'm going to start a nitrogen tire filling chain!!! it is a more stable gas that is not as affected by temperature Ok, so whats the thermal expansion rate of atmosphere VS nitrogen per mole (22.4liters) ? Remember... air is already 78% nitrogen... It contains roughly 78% nitrogen, (normally inert except upon electrolysis by lightning[1] and in certain biochemical processes of nitrogen fixation), 21% oxygen, 0.93% argon, 0.04% carbon dioxide, and trace amounts of other gases, in addition to about 3% water vapor B Link to comment Share on other sites More sharing options...
Simon Posted March 21, 2007 Share Posted March 21, 2007 Well, I would have thought the same a few months ago, but my dad bought new tires for his car, and for an extra $10 CDN, they put in Nitrogen, instead of air. Over the winter he did not loose 1 PSI......his air pressure did not change, at all.......Granted, it's only about 6 months of testing so far, but I am impressed at this point.

SC88Pathy Posted March 21, 2007 Share Posted March 21, 2007 At the tire shop that I go to they fill your tires with nitrogen for free when you buy a set of tires from them. You even get cool little green air nozzle cap thingamadoodles to let everyone know you're special and have nitrogen filled tires. Link to comment Share on other sites More sharing options...
94extreme Posted March 21, 2007 Share Posted March 21, 2007 hahaha sc simon, my tire shop always fills mine with nitrogen regadless. they do seem to stay longer at the desired psi, but like b said, i really have no issue to bump the psi once in a while anyway.

Pavelow Leaks Posted March 21, 2007 Share Posted March 21, 2007 The reason for running nitrogen is becuase it doesn't react to temperature changes as much. It's more noticable on aircraft, or heavy equipment, when the air temps warm up or cool down the tire pressure is affected, and becomes a safety issue. I run nitrogen in my tires only because I have access to a self generating nitrogen cart we use to fill aircraft tires. I wouldn't go out paying for it though, as long as you keep an eye on your tire pressure, there's no need. Link to comment Share on other sites More sharing options...

OH, nor do I, or does my dad.....since it was only $10, and he was curious, he did it. I'd say for a car driven by a woman like my ex, who couldn't be trusted to track 5000kms between oil changes, it'd be great. For anyone else, it's just an added expense.

mws Posted March 21, 2007 Share Posted March 21, 2007 Run nitrogen = good Charge $40 after the fact = shady Link to comment Share on other sites More sharing options...
Ultrafinder Posted March 21, 2007 Author Share Posted March 21, 2007 Well its obvious that Nirogen is good, glad for that. We all also agree that it was shady to charge $40 for it and, after fact. Thanks for all replies Link to comment Share on other sites More sharing options...
