Better Fuel Economy, Longer Tire Life, Enhanced Safety, a Smaller Carbon Footprint… and So Much More.
High purity nitrogen has been used as a tire inflation medium in critical applications, where safety, precision and economy are paramount concerns, for decades. The FAA mandates the use of nitrogen in all jet aircraft tires, it is the inflation standard in countless military vehicles, and is also required by Nascar, Formula One and most racing venues. Unfortunately, the high cost and complexities of generating and properly administering nitrogen have kept it out of the reach of the general motoring public until recently.
What makes nitrogen such a great inflation gas for tires? Actually, nothing… or more precisely, the fact that it is nothing. And nothing is exactly what tires should be filled with, as in: nothing but pressure. So if nitrogen is nothing, it can't possibly be beneficial… at least until you compare it to the alternative: air.
