Nitrogen filled tires?

Apparently mixing nitrogen and regular air doesn't cause them to explode or anything.

Hi Ronzi, I think the Honda dealership was trying to do you a favor by NOT adding air to your nitrogen fill, and diluting the ratio. Now, if you don't care about the % of nitrogen, just let them know the next time. The green caps are their warning to not fill with regular air.
