Nitrogen Tyre Filling
What makes nitrogen such a great inflation gas for tires? Actually, nothing… or more precisely, the fact that it is nothing. Nitrogen is an "inert" gas, meaning it's a property-free, non-reactive substance or, more simply put: "nothing." And nothing is exactly what tires should be filled with, as in: nothing but pressure.
Proper tire pressure is a big deal.
Maintain it with nitrogen, and you'll see
these three primary benefits:
Increased Fuel Efficiency – Correct tire pressure keeps the manufacturer's recommended "contact patch" on the road. This lessens the rolling resistance and maximizes fuel efficiency.
Longer Tire Life – When it comes in contact with other materials, oxygen causes oxidation. Oxidation can make rubber brittle and cause it to lose tensile strength. In addition, at high temperatures and pressures, oxygen reacts and damages inner tire liners and belt packages; nitrogen does not.
Increased Safety – Under-inflated tires cause 90% of blowouts. Nitrogen provides more reliable pressure for reduced blowout potential.
