Air vs. Nitrogen filled tires

[PennTitan]

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.

Read all of this and make your own decision:

Got Tires filled with Nitrogen.

[fherjohn]

i heard that there is no real diffrence.

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?

[phugoid]

why do tires need air anywaz????

The Truth about filling your tires with Nitrogen.

[ArmyAviation]

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

[IAPharmr]

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.

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.
