Whos Using Nitrogen and Why?
Nitrogen (N2) has been used to fill tires in the trucking, construction, military and fleet industries for several years. The main reason has been the durability of tires (we’re not talking 75-buck rubber here), but also for safety and better mileage. The aviation industry has used N2 in planes for safety, durability and reliability under extreme temperature variations. The tires on a passenger jet flying at 30,000 ft. may be exposed to temps of 30 deg. F., then have to land on a scorching 130 deg. F. tarmac runway. There’s just no tolerance allowed for underinflated tires in such situations. NASCAR uses bottled N2 for convenience – as does the Formula 1 Series for safety, durability, fire retardation (N2 doesn’t fuel combustion like the oxygen in air does) and reliability under temperature extremes. Recently, many chain service facilities (mostly tire stores) have chosen to use N2 for tire filling. Oddly, their business is to replace worn tires, but the service fees for N2 filling and
