I've just got it done yesterday. I thought you guys should check it out. It only costs $6 per tire. Go here for details http://www.whynitrofill.com

Here are the highlights...

Benefits of Nitrogen

Increases Safety

In 7 million miles of truck tire testing, nitrogen inflated tires lasted longer.
Tire failures were reduced by 50%
Tread life was increased by 25-30%
Fuel economy was increased by 5-6%





Improves Performance

Improves steering
Improves handling
Improves braking
Reduces chance of tire failure





Saves Time, Money, and Tires

Dramatically slows pressure loss from permeation
Stabilizes pressure and virtually eliminates pressure fluctuations due to temperature change
Reduces tire oxidation
Eliminates interior wheel corrosion
Reduces running temperatures
Decreases false alarms and activation of Tire Pressure Monitoring Systems

 

That would actually work great if you don't race and set the tire pressure at certain PSI and forget about it. If you race and constantly adjust your tire pressure, not so practical unless you easily have access to it. I think I would just stick to filling air and checking pressure every once in a while. I seriously doubt you would get anywhere closed to those claimed percentages in G.

 

Yea and if you have Costco membership, they fill up all tires with N2 and whenever your tires are flat, take it back to them and it's free.

 

Anyone know where I could do this in Houston? Costco says the only do it when you purchase new tires.

 

I have been doing it for 2 years now. Seems to work awesome for me.

 

yea but can you trust those costco guys with your rims?

 

Plus Costco doesn't carry tires for 19" rims

 

Some of the stuff that company says is plain untrue. The part about "Recent advances in nitrogen production technology have made on-site generation economically viable for the automotive service industry." Thats complete and total BS. There are no major advances in Nitrogen production. Nitrogen is an inert gas that is stored in tanks, can be transported easily and is much safer and less restrictions than oxygen (flammable) The reason people (auto shops, tire shop, gas station, you and me) use air is because its FREE. Buy a compressor and you have all the air you want, like the guy before me said Spending money on the air fill takes away from any monetary benefits you would gain. BTW I pay about $30 bucks at work for 99% pure lab grade nitrogen in a 5 foot 2600 psi bottle. It's not some exotic and expensive gas.

The one thing I can speak to is the thermal expansion properties of nitrogen are better than plain air so your tire pressure would be more stable with temperature swings. So your tire wear would decrease significantly, but not if you are the diligent type who always makes sure you tires are properly inflated, then the tread saving would be less significant for sure. Now that being said do you think the major Tire companies are anxious to have their tires last longer, meaning not as many sales? Probably not, at least not yet. Nitrogen is a superior product for tire fill but not yet practical since consumers have to pay for it and tire shops are not likely to add the service except in the case where they charge you for it.

 

I could have ordered 19" tires from the Costco here. They just didn't have them in stock, but are available.

 

well said SDG

 

I think that the advances they speak of are the small production nitrogen generators that are being installed on site.

They weren't talking about LIQUID nitrogen!
