trogen filled tires

[Threepoint]

$20? Sheesh! Last I checked, Costco Tire Centers all use nitrogen when you buy the tires from them, and top up for free thereafter. Don't know about Sam's Club, but they may do the same.

The theory is that nitrogen will be less affected by temperature changes than air which is why racers sometimes use it. Absolutely no real world advantage for street use.

Should You Fill Your Car's Tires With Nitrogen?

Is Nitrogen Worth It?
The air we breathe is made up of 78 percent nitrogen, 21 percent oxygen and a few other elements. To get the desired benefits for tires, nitrogen needs to be at least 93 percent pure, according to nitrogen service equipment providers quoted on Tirerack.com. So we're basically talking about adding an extra 15 percent of nitrogen and getting rid of as much oxygen as possible.

Based on cost, convenience and actual performance benefit, we don't think nitrogen is worth it. A much better use of your money would be to buy a good tire-pressure gauge and check your tires frequently. This is a good idea even if you have a tire-pressure monitoring system in your vehicle. The warning lights aren't required to come on until you have less than 25 percent of the recommended tire pressure. Having the correct tire pressure will get you many of the benefits of using nitrogen and will ensure that your tires last longer.

That should pretty well end this discussion. But, if you are fan and you have lots of money and time by all means fill your tires with nitrogen.

Nitrogen has larger molecules than oxygen and should leak out of tire slower. The benefit of nitrogen is if you do not check tire pressure as recommended.

I thought he was putting trogen in his tires?

It's NOT THE NITROGEN that the racers use and you might be getting for your $20

IT"S the DRY GAS that is used to inflate the tires. Water is terrible in regard to it's change of partial pressure with temperature.
In reality, Dry air is every bit as good as "nitrogen". Nitrogen is just any easy way to get dry gas.

So for us in the humid regions, Pump up your tire filling tanks in the cold of winter when the air is dry.
For those in arid SW, just use whatever comes out of the air hose! ;-)

Maybe it's Trojan?

(Can't help myself)
Be sure you get the right one for ribbed or studded tires.

When a tire place fills a tire with nitrogen, if they don't remove all the air first, there is still oxygen in the tire.

Or do they fill and deflate several times to get most of the "air" out?
