Benefits of nitrogen inflation:

  • Maintains more stable tire pressure – higher gas mileage
  • Dry and non-flammable – resists corrosion and fire
  • Does not expand or contract with temperatures as much as oxygen

Nitrogen is commonly used in the tires of space shuttles, race cars, military vehicles, airplanes, and other heavy equipment. Nitrogen inflation is more reliable than using oxygen in extreme conditions.

Located in Des Moines, IA, Stephens Automotive is happy to assess your needs and aid in your decision between oxygen and nitrogen filled tires.

Is it okay to mix nitrogen and oxygen?

If you decide to fill your tires with nitrogen and need a spare tire, it’s totally fine to fill that tire with oxygen. You can also top off your nitrogen filled tires with oxygen if the need arises. There’s no danger to mixing them since regular air for tires already has a nitrogen component. The only difference is that you won’t experience as many benefits with a lower nitrogen percentage. It’s important to have your tires filled to ensure good gas mileage and fewer emissions.

We would love to keep your vehicle working as efficiently and reliably as possible in all weather conditions. Stephens Automotive proudly meets the nitrogen inflation needs of customers in Des Moines, IA and surrounding areas.
