I'm getting my new tires tomorrow (Firestone Destination A/T's). I'm not sure if I should go with nitrogen or just air in the new tires. Nitrogen lasts longer with not much, if any change, in tire pressure but is it worth the $20 bucks????

Any input would be great. Thanks!!!

it all depends on if you have access to a air compressor. With air you can add all you want whenever you need but usually it costs you some quarters each time. My 05 wheels drop 15psi really fast so I have to watch my tire pressure regulary and top it off every few months. with the 100% nitrogen they claim you won't have to top them off. (drawback is that if you need to top off you can't just add air)

Bottom line... I wouldnt pay 20 bucks to get it done. places like costco do it for nothing. Remember air is 79% nitrogen to begin with. :cheers:

I know very little about Nitrogen. I do know that apparently, temperature changes don't effect tire pressures like air filled tires. I guess one has to determine if that alone is worth paying to fill their tires. To each his own. I have no opinion either way since I have a compressor and check my pressures regularly on all my vehicles.

How would they purge the air out of the tire after it is mounted on the rim?

Nitrogen is for aircraft tires not cars. Aircraft need nitrogen for high altitude and temp

Nitrogen is not affected as much by temperature. That is why you will hear about race cars etc filling tires with it because it will not affect the tire pressure as the tire heats up thus changing their traction characteristics.

So Unless you are going to be pushing your Titan to the rev limiter or doing 180 every day, it should not be a huge deal, for an extra $20 I will keep my own air and have a few beers and a round of pool!

Plus all the other reasons in all those other articles referenced on this thread

Remember it is all in PV=nRT or P=nRT/V......

I bought my 2008 Pro-4X Saturday and it came with Nitrogen already in the tires and a little piece of cardboard attached to the key fob. I didn't know Nissan delivered with Nitrogen or maybe the dealer did it.:rolleyes:

NItrogen I feel is a huge gimmick. I work at jiffy lube and we check peoples tires when they come in. nitrogen filled tires are always low just like regular tires. and we do calibrate our guages... we don't add air right away we ask the customer if they'd like us too first. you should hear some of the responses.

I wouldn't bother. air is what 70 something percent nitrogen anyway whats another 20 percent gonna do in our trucks

you should check for leaks, no matter what is filling them it should never go down unless theres a problem or you drop pressure on purpose

I have had my toyo m/t's for atleast 6 months and I don't think I have had to add any air. I check them regularly, but they are always still around 50 psi.

Nitrogen is not the end all be all. In fact, if you pay for it...well....the word idiot comes to mind.

Nitrogen is, in fact, susseptable(sp) to ambient air temperature changes. The pressure will go up and down depending on tire temp. It may not be as drastic as air, but it does move. I work with nitrogen every day on helicopter tires and accumulators that are all precharged with nitrogen. There are very specific and calibrated charts that display the temp changes.

Anyways, I would not ever pay for it. Even if Costco uses it "for free" I would be to lazy to go there just for tire servicing...especially since I have an air compressor in my garage.

What are you buying tires at costco for, anyways??

If you work with Nitrogen, you know that no....Nitrogen is NOT susceptible to ambient temperature changes anywhere NEAR regular air. Which is why race cars teams can adjust as little as a 1/4 LB at each corner to change handling. Your line of work must be a LOT more precise than needed for automotive use. I personally wouldn't pay for Nitrogen but unlike air filled tires, which can lose between 1 and 2 PSI a month, Nitrogen filled tires hold their pressure. Nitrogen also won't corrode rubber or rims like regular air can.

We also use nitrogen in our helicopter tires, and they still need serviced every now and then. Nitrogen pressure does fluctuate with temp and altitude, just not as much as regular air. I can get all the free nitrogen I want and I don't use it in my tires, just no real advantage for regular use. Like master 1011 said, there are charts near the wheels on all aircraft that will tell you what the pressure should be at a certain temp. We also use nitrogen in our emergency float systems, and I will fluctuate quite a bit on real hot days, and cold nights.

this time of year here in MD we have very high swings in temperature and it plays havock on tire pressure. I don't have any leaks it just is what it is.
