I call BS.

I have seen claims that filling your tires with nitrogen will net you up to +20% MPG and some how the pressure doesn't change with temperature and it some how doesn't leak down like air (ha!). As if nitrogen is some how exempt from Boyle's law.

Back in 2006 I tested it and saw no improvements in fuel economy and charted pressure and temperature changes on par with air. Who would have thought since nitrogen only makes up 78% of air?


I just ran 36,452 miles on Kuhmo 255/45/18 w/ nitro. Having just run 3 sets before on 02 for 120,000 miles.
The psi never fluctuated with the nitro. with the 02 there was always fluctuation.
and it was very easy to tell.........
The Q45 has psi sensor sytem that displays the exact psi on the screen.

show me in PRINT where some one claims the nitro doesn't 'leak' out? An idiot knows that a leak is a leak. nitro doesn't fluctuate.
