I've been looking at the debate & came across this article:

...which seems to sway me towards saving my dough.

Save your money, I have read all the studies and unless you let you car sit for long periods of time, it really is not worth it.

I think I saw an episode of Mythbusters where their conclusion as well was it was BS............

My motorcycle dealer was offering free Nitrogen with the purchase of a tire so i have it in my motorcycle, and yes the pressure levels have stayed consistent, especially since its been sitting a lot due to winter. Would i purchase it for the car, NO

I only put nitrogen in my tires! Costco will fill them up free of charge and it DOES make a difference. I routinely drive where the weather changes more than 40 degrees F within a few hours. This happens every time I drive from the Front Range to the Vail Valley. I actually checked the pressure and it stays constant in spite of the huge temperature change. Also, I store my tires depending on the season, so it does seem to hold pressure better when I hang them up in my garage for months at a time. Well worth it here in Colorado.

Unless one lives in a climate with pretty extreme temp changes, I would stay with air.

I have an air compressor in the garage and always fill the tires to appropriate specs when cold in the morning fro my fleet. They drop about a pound for each 10 degree drop in ambient temparature, keeping them properly inflated in the cold months is key to safe driving.

And what if you lose couple of psi in the tire, how much are they charging you to fill it back up. To me, it'll be ok to pay the up front $40.00. But once it lose couple of psi, now what? Pay more?

Davel

Good point, but most places will top off for free it you purchased the nitrogen from them. The problem is if your traveling then you would have to pay to have nitrogen added.

SAguirre

It is not a real big deal. They top off the tire free of charge every time I need it, which has only been once! Also, if I do need to put some regular air in the tire when I am away, it is also no big deal to put 2 or 3 PSI of pressure that is about 78% nitrogen anyway. This is a very minor Oxygen pollution in the tire.

The Costco people (who have been at the Costco I got to for the last 7 years) are very helpful and friendly.

Maybe it wouldn't be a bad idea to fill the donut spare with Nitrogen then, since its used/inspected so infrequently.

Davel

Thanks, thats good to know, i'm using it in the motorcycle where a few PSIs low can seriously effect the handling...

Barry,

If you have TPMS use nitrogen.
Solid, even, readings on nitrogen.

I would not be surprised if the TPMS sensor ($230 ea) in the tire, were to last longer in the dry inert nitrogen, as opposed to an humid oxygenated (corrosive) fill gas=air.

I am investigating various Nitrogen Generators, one that will easily fit in my garage or shed.
