Adding air to tires
 
Is there a way to add nitrogen to your tires at home? Cold weather finally set in and my tires are showing a little low. I was told that you can add air and just replace at a later date.

Are you telling me our cars tires come nitrogen filled? Or did you have them filled?

My car came with nitrogen check the caps on your valve stems, I got 2 sets, one has a N on the top.

Maybe his dealer put it in. I think mine did because the stems have a green cap.

I don't think you could do it unless you had a nitrogen tank. The tire places have a machine that removes the O2 from the air. It's too much trouble to go to a tire store and have them put air in, so I've decided nitrogen is more trouble than its worth.

I'm sure others will chime in on this. Just add air to them. The nitrogen is a joke if you ask me. I thought I would try it out when we got new tires on our Acadia. I kept fuel mileage records and the nitrogen didn't make a difference. Also the pressure changed just as much with the heat and cold like normal air did. So to me it was a waste of money. Unfortunately my camaro came new with nitrogen filled tires that the dealer installed. I had to pay for that, not like I could have them reclaim it and refill with normal air. I was tired and just wanted to get my baby home. They already took the pinstripe off for me at no charge. Heck, the air we breath is 78% nitrogen anyway.

I just went out and checked. No green caps with N on them and I didn't read anything when I got the car about nitrogen. So I'm thinking I'm ok cuz I added air to over inflate them for winter storage on the car. Thanks for the response. :thumbsup:

You either get a cap with a green N on it of just green caps to indicate you have nitrogen in the tires.

The Nitrogen still leaked out of my Accords tires over time, so I decided not to use it again. The Camaro has been a little more stable. I think the dealers add it for mark up and to reduce complaints about the air pressure sensors since it is supposed to not leak out as fast.

We use nitrogen in our race tires and find the pressure dosen't grow as much due to less moisture.
Nitrogen in car DD tires is a waste of money, just maintain your car and keep the inflation in check. IMO

I would beg to differ with the thinking re; nitrogen. We purchased nitrogen machines in some dealerships we owned. I installed nitrogen in all my performance cars and it held an absolute pressure cold or hot and did not require adding more nitrogen or air for nearly 12 months in my Porsche turbo as an example. I am a nut about tire pressure and check it offen. If an installer has a good nitrogen machine it first cycles out all the air, and then it installs the nitrogen to the set pressure. Nitrogen is 99% dry and therefore is not technically affected by ambient air temps. Tires also carry less heat in hot temps with nitrogen.

I have a nitrogen tank at home with a regulator, I have nitrogen already for the plane. If it is dry air it will be ok, air is about 80% nitrogen. It is the water in the air they do not want to get to the sensors. Nitrogen leaks out just like air. We use nitrogen because of the high pressure and dry air. When you fill your tires with air it's no different than nitrogen, as long as it is dry.

the shops do not remove O2, they remove the water with a air conditioner type unit the cools the air to get the water out.

The dealer tried to sell me nitrogen fills for my tires, that a load of crap and a waist of money.

You are right, as long as the air does not have allot of water in it.

got any info that backs up the tire hold less heat with nitrogen? Nitrogen can be heated just like all other gases.

....I use my air compressor and ad moisture laden O2 to my ZL1 tires when they get low, so....is that a bad thing? Do I go any less faster or cause any harm to my rims or tires? Am I causing harm to anything other than my credit card balance for doing same? What's the risk/reward for doing the cheap air versus the alternate route. I am not gonna race a full weekend on a road course. I've done the air compressor route forever with no harm. It's champagne versus beer. Drink what you can afford I guess, or whatever works best for you.

It will be fine, the air will be ok for the tires. I think it is all a snake oil gig to make money.

Just like the fix all transmission oil that will fix your transmission for $15. It crazy.
Tires will be worn out before any air would hurt them.
