Nitrogen in tires, where to fill up?

SO THATS WHY YOU BECAME MY FRIEND!!!!

JK, besides at Costco we will top anyone off at the very least if you just pull up outside the tire bays and ask for an air check.

LOL!!! I never came to YOUR Costco!!! But the other Costco did rack up my car, let all the air out then refilled them with Nitrogen

Nitrogen has its place - in aircraft tires for example. For street tires though, no. The nitrogen hype is a money grab. I've used 78-80% nitrogen for over 40 years in my tires. Not once has a tire of mine disintegrated from plain old air. My vette has had its tires on since 1995. They are due to be replaced due to age - not because they are rotten with a lack of pure nitrogen. Save your money!

mainly nitrogen is less susceptible to pressure changes when the air temperature changes. So basically your tpms will be more accurate.

"So, to answer your specific questions: With nitrogen, your tire pressures will remain more constant, saving you a small amount in fuel and tire-maintenance costs. There will be less moisture inside your tires, meaning less corrosion on your wheels. You will not be able to feel any difference in the ride or handling or braking, unless your tire pressures were seriously out of spec and changing to nitrogen brought them back to the proper numbers."

Now, do I only put pure nitrogen in my tires? Nope!

Mine came filled with nitrogen from the dealer. I top it off with regular compressed air.

They fill up. Serious.

Are you a Nitrogen salesman?

If you want me to prove its a scam, I can. But I am not going to take the time..

Water = H2O wonder what the O stands for??

Most tire shops around here (S Arkansas) carry N2.

Doesn't make sense to me, but you may be in a more remote area than I am.

Not much. There are some minor advantages to N2 (see posts above - IMNSHO the biggest one is TPMS sensor corrosion and that shouldn't be anything major), but just adding some air to your N2-inflated tire will not do any damage (assuming it is reasonably clean and doesn't contain too much oil or other contaminates). Only 20-something% of what you're adding is not N2 and you're only adding a small amount, so you're not diluting it by much.
There will more than likely be some water entrained in the air (how much depends on the compressor setup, humidity, &c), but it should be minimal and the N2 that is already in the tire will absorb some of it.
Unless you are obsessive about having 100% N2 in your tires, all you need to do is have the tire(s) bled down and refilled with N2 at your convenience. If this is the only time you've added air, I wouldn't give it a second thought.

Edit: Neither Goodyear nor Hankook even mention N2, much less recommend it. YMMV

No, but if you DRINK it you will oxygenate your blood.

Drinking plenty of water ensures that your blood will carry plenty of oxygen to all the cells of your body. This means that all of your body's systems will function adequately, because they'll be getting plenty of oxygen. Your immune system functions best when your muscles and organs are functioning best.

pee in a pond. the benefit to hassle/expense ratio is a joke. I race offroad, have my own nitrogen setup for the shocks. guess what's in all my tires. A good friend has a high end tire shop, for many many years.... how many sensors is he replacing due to corrosion? zero. drink the koolaid all u want.

Is it better? yes, is it worth it or needed? hell no. what's it cost the dealers to fill four Z tires? $2-300 in initial equipment and about $2 for each car, if that.

Do NOT do this, if you add regular atmospheric air to a tire that contains pure nitrogen, the resulting exothermic reaction once the tires heat up can trigger rapid atom-shearing which can set off a chain reaction degranulating the nitrogen atoms which has been shown to combust, destroying your car and any surrounding cars in traffic.

Below is a picture (taken from CNN) of a car which was filled up with regular air when it already had nitrogen in its tires:

In all seriousness though, normal air may fluctuate a little more with temp changes outside and may leak a teensy bit more. So just check your tire pressures. On track pure nitrogen would expand less I assume making tire pressures and thus temps fluctuate less but I have yet to see anyone use nitrogen on track regularly.
