i have a 2007 ultra classic Harley Davidson I was wondering what all you think about putting nitrogen in my tires.. will this keep then cool while riding double?

 

Some people use nitrogen, some don't.

It is a matter of personal preference.
It is like starting an oil thread. Everyone has the perfect solution.

 

nitrogen has larger molecules than 20% of the pump air ( 80% of atmosphere is nitrogen anyways)- those larger molecules are slower to migrate through the rubber- so your inflation stays more stable over a longer period.

nitrogen doesn;t expand like "air" when subjected to heat or changes in elevation*.


which is good- that's why race cars use nitrogen, the tire pressure stays stable lap after lap

I have no idea as to whether your tires will be cooler- overheated tires are often under inflated and the sidewall flex creates heat...and the tire may fail

I took my little tank to costco and the guys filled it for me.

* a casual dayride in AZ can have a 7000' variation in elevation.

 

Leeeets geeeeeeeet rrrreeeeeeeeaaaaaaddddyyyy to ruuuuuummmbllleeee!!!!!

 

The idea in using N2 is that N2 doesn't expand and contract due to heating and cooling of the tire as much as O2 does, thus resulting in a more constant pressure in the tire, it won't keep your tires running any cooler just because it N2. It's up to you if you want to run it or not, I myself don't think it's worth the hassle.

 

A HUGE thread already exist on this.

Do whatever you wish. Or perhaps ask the guys at the tire shop or Harley shop if they run nitrogen.

 

I used nitrogen and most of the teams that I raced against used it as well. A tire is like a spring, more air stiffer, less softer, nitrogen will not change as much as air. If I went out for a ten lap session with air, the tire pressure would go up at least 10lbs, with nitrogen 3 or 4lbs, that makes a big difference in the way the car handles. Nitrogen also does not leak down as quick. It will not make your tires run cooler and you will not notice a handling difference on your bike, but the tires will not leak down as quickly. Is it worth paying for nitrogen in your bike, I would say no, in a race car, yes, just my opinion.

 

Its important to remember that nitrogen is exempt from physics and all equations relating to gasses. It is a truly magical material. ;-)

 

You honestly believe it makes that much of a difference?

 

Time for someone to post that photo of the headache guy.
