"TireBlast TM" Canadian tire verging on unicornian claims
 

Nitrogen tire inflation
Improves fuel economy
Increases tire life
Less loss of tire pressure helps prevent uneven tire wear
Reduces wheel corrosion
Tires run cooler adding tire life

Then they sum it all up in a sentence just for "clarity"

"Nitrogen tire filling will increase safety and reduce operating costs, while improving the performance of the vehicle."

$6.95 per tire.

All that for just 6.95? Such a bargain!!1! So how to they get all the old horrible wasteful regular 78% nitrogen air out completely? They must pull a 100% vacuum before right? right?

The biggest reason they left out: Avoid those terrible tire fires you have heard so much about.

Anyone wish to do the cost/benefit analysis and return period?

For the same price, and can fill several tires.

And works anywhere you have your car.

But... but... but...

You'd be filling those tires with contaminated nitrogen! Ewwwww! :rolleyes:

It's dry nitrogen tho, after all on average the air going in to your engine as as much water in it as gasoline as it enters the combustion chamber, so while I question if it's worth the cost, it does have an affect, airplanes use nitrogen in their tires to keep them stable, of course your car is not seeing the changes an airplane sees.

On my last set of tires, I had Radial Tire Store of Sacramento, put nitro in the tires. we had discussed it half way thru my last set and he said that it really needs to be done when the new tire is installed.
I run 44psi w nitro and the psi fluctuates 1psi (the Q45 has psi senors. In the past it was as much as 4psi different hot and cold.
The trip that is documented in my signature (third link) was my first ever over 30mpg.
I reallt thing the nitro played a role in that.

Really, though, the slightly increased stability of psi may really be the only material advantage. So if your peak psi is a bit higher without the nitrogen it's not going to be doing you $27.80 plus tax better any time soon.

Gotta love the ill chosen name: TireBlast. Heh heh.

"Neglect your tire pressure even more with TireBast!"

Though you are all missing the major benefit of the nitrogen filling - the green valve stem caps you get!

^^^ they probably make a killing off of that stuff. I can do the same thing by using an air compressor and paying attention to the pressure by checking it weekly.
