My dealer filled my tires with 78% nitrogen. Seems to work pretty good...
I do too when I bring the tires back up to proper level. No wonder i'm not noticing the "difference".

I'm running the recommended 36/42 and have felt no reason to change. I'm still waiting to discover the mysterious benefit I will get from having nitrogen in the tires.
The benefit is that nitrogen doesn't expand (or contract) nearly as much as oxygen does, so fewer cold-weather low-pressure situation.
I really didn't expect this to turn into such a lengthy thread! I pulled into Discount Tire on my way to work (where the general response was "why does that car only have two wheels?') when I found out that the dealership had overinflated the back tire. Thank you all for the great info here!
In the Prius world it's common to run 3PSI over spec to get better mileage. On that note, I replaced my totaled white one with a 2014 red one to match the CB! CB doesn't need a solar panel to keep the interior cool though

If that is the benefit, it's strictly a placebo effect. I have had to adjust pressure in the CB's tires as often as I have done so in the wife's V-strom which has the "78%" mixture. My limited knowledge about Boyle's Law and my many years as a scuba diver would lead me to believe that no one could truly see a difference in the expansion rate of pure nitrogen and "air" which is mostly nitrogen. I would think the moisture content would have far more to do with it as bottled nitrogen is essentially "dry" with near zero moisture content. On the other hand, using nitrogen would not have any adverse effect either.
