Nitrogen in the tires- your opinions please?

[infin in nj]

I recently took my 2002 I35 to the dealer for routine service. They suggested a new tire service where they replace the air with nitrogen. Its supposed to improve the smoothness of the ride, improve gas mileage, be safer...

What are your thoughts? Have any of you tried it? Should I invest in this...

Thanks!

i just brought an 04 i35 with the nitro in the tires and the ride is alittle smother. the gas mileage is BS. but its the smooth ride that counts to me. good luck.

it won't improve anything but the amount of money they'll charge you extra nitro is used in tires because it doesn't leak out as easily as air since the particles are bigger. i believe costco puts it in tires when you get replacements from them and idk but i don't think they charge extra.the smoothness of the ride depends on the quality of tires, psi, and a few other things - not what was used to inflate them.

Its all in the head, man.

Well I know the GTR has Nitrogen in the tires as well. I am not sure why but I think its because nitrogen doesn't expand and or shrink when the tires are warm or cold. So like when the tire says fill to 28 PSI COLD. it wont really matter what temp it is and the tire pressure wont fluctuate with the temp! that and its supposed to hold its pressure better when its been punctured. due to the nitrogen particles being larger.

If its free I would get it, like at Costco. but if they are charging then I wouldn't.

Unless you're running racing slicks I wouldn't bother. The only reason I've ever used Nitrogen in my tires was with Hoosier racing slicks, in which the temperature increase of being on the track would cause a large increase of pressure in the tires.

I highly doubt the particle size will effect it much, Nitrogen and Oxygen are next to each other on the periodic table. This causes them to be very close in features, Oxygen actually weighs more so I'd consider the difference negligible.

What's the cost difference?

As was stated above. Nitrogen is an inert gas and not affected by changes in temp. It also dosn't condesate when cold which is supposed to help combat dry rotting on the inside of the tire.

I use Nitrogen in my tires only because I get it for free. But I have noticed that I don't have to add pressure in the tires as often as I did with regular atmospheric air. As for difference in ride or mileage...there are none.

This guy is spot on.

We have used Nitrogen in aircraft tires for decades for these very reasons. It's more reliable in keeping your tires inflated to the proper psi, assuming you don't have a leak.
