Nitrogen is non-combustible, non-flammable, non-corrosive and is safe when used in tyres. It has a larger molecule size than oxygen and helps stabilise a tyre’s inflation pressure. Oxygen escapes from a tyre three to four times faster than nitrogen. Maximise your vehicle’s handling, fuel efficiency and tyre life by purchasing your tyres filled with nitrogen at Costco. Because your time is valuable.
Air is also 78% nitrogen
