Nitrogen-inflated tires: Cool!
By Aida Sevilla MendozaMy car’s tires are cool—not because they shod expensive aftermarket rims, but because they are inflated with pure nitrogen. Filling nitrogen in tires helps to keep the insides of the tires cool, even at high speeds. Thus the valve caps of my tires are green, indicating cool, eco-friendly nitrogen content that enhances fuel efficiency.
