Charles Law and Boyles Law - know them well - that's what I do for a living. Air in my tires.

 

Not going to get scientific but I did test the Nitro in my F-150. I filled 3 of 4 tires with Nitro and one with air. Here in NC we see temp changes like crazy this time of year. For example Today is a high of 40, tomorrow, 40, Monday 67. I only wanted it because the stupid low tire pressure light in my truck always comes on during temp changes. The only tire that pressure changed in was the air filled tire. I was sold and filled all my tires with nitro. I got on today to see if anyone was running it in their bikes because my tire pressures on my bike are changing every day it seems. I'm new to motorcycles and recently bought my first Harley so every time I ride I'm doing the new guy shuffle and checking everything. Yesterday when I checked my front was down 5 lbs and rear 4 lbs. We've been stuck with highs in the 20's most of the week and I haven't taken it out until yesterday. I'm going to try Nitro on my bike. Seems to work good on my truck.

 

I recently had a flat tire and I don't have Nitro at my dealer so had to put regular air in one tire. It's been almost 3 weeks now and I gotta tell you that the one air filled tire starts off at 33 psi cold and gets up to 38psi on hotter days here in South Florida. My cars TPMS sensor actually display the psi in each tire and you can see the pressure increase after you start driving. BTW the other 3 tires with Nitro start at 32 psi and don't fluctuate more than a pound or 2 even on the hottest day at highway speed.

I run a car dealer and I'm getting the Nitrofill on my bike for free but I'd gladly pay for the stuff.
I don't care what anyone says. The stuff works!!!!

Keep in mind that I thought it was useless and that their claims where bogus when I first heard of it. I didn't complain when it came on my new car for free and after driving on nitro for 18 months I am a believer.

 

I thought this made for some interesting reading. Draw your own conclusions.

Let's not go bringing facts and scientific data into the argument. Someone's cousin's buddy tested this theory on his 1978 Ford half ton driving from Conneticut to New Mexico, and the guy that changes his oil down at the quikkielube told him N2 was better.

 

Facts and scientific data are all fine and dandy but the stuff works in real life applications.

 

Not lookin' to bust them but if you're so convinced it works then why did you start the thread asking opinions? As they say "Just Do It"!

 

The facts and scientific data come from careful observation and recording of what is happening in real life.

The arbitrary perceptions of the hopeful consumer is not "real life". This is almost always post-purchase rationalization which is one of the common cognative biases that in short, make people think wrong.

Here's a list of them, it's fun, and humbling.
