Filling tires with nitrogen rather than air is becoming a common practice in the replacement tire market. The safety benefits often include the potential for reducing air loss compared to an air-filled tire.
Maintaining proper inflation can help prevent tire overheating; promote optimum tread life; and reduce rubber aging and wheel corrosion. The use of nitrogen in large truck fleets and the commercial tire industry are well documented and support these claims.
We now have a Nitrogen Fill Station. Cars $20 / Trucks $40 (includes drain & fill)
