Why Inflate with Nitrogen?
Compressed air is your tire’s worst enemy. Air is about 78% nitrogen, 21% oxygen, and 1% other. Nitrogen is inert, non combustible and non corrosive. Oxygen, on the other hand, is immensely destructive to rubber and other tire materials. As soon as a tire is manufactured and exposed to air, the effects of “oxidation” begin to deteriorate the rubber. Over time it loses its elasticity and strength, just like an old rubber band you've probably found around your home. This same process occurs in tires inflated with air as the oxygen attacks the rubber molecules, working from the inside out, until the oxygen, and its destructive properties, permeates the tire structure and ultimately the tread.

Is All Nitrogen Gas Equal?
No, the purity of nitrogen available from automotive service facilities varies greatly. To enjoy the benefits of nitrogen inflation, you must have a minimum "in-tire" purity of 95%. This is easy to verify with the use of a "nitrogen purity analyzer," a common tool that your Go Green™ nitrogen dealer will probably have on hand. It only take a few seconds to check and will give you both peace of mind.

My Tires are Low! Now What?
Low tire pressure is generally due to one of the following three conditions:

1. A leak. Most tire leaks are the result of a hole or puncture, faulty valve, or a porous or corroded wheel.
2. Permeation. Permeation is the normal process by which the air in a tire bleeds through the tire's body or carcass. It is typical for an "air" filled tire to lose 1-2 psi of pressure every month through normal permeation whereas it can take several months for a nitrogen filled tire to lose a single pound of pressure.
3. Temperature Change. All gases expand and contract with temperature. If you live in an area that experiences dramatic temperature changes, you will have to adjust your tire pressure accordingly. Typically you will only have to adjust your tire pressure "up", adding pressure as ambient temperatures decrease. Count on losing about 2% of your total tire pressure for every 10 degrees in temperature reduction.

Participating Go Green™ dealers will always check and correct your tire pressure with nitrogen for free during your membership period, and we recommend you have this done every 30 days if possible, or as often as your schedule permits. If you have nitrogen in your tires and do not have a leak, you should experience little or no pressure loss from permeation, but may still see pressure loss from seasonal temperature changes. While it is best to visit your Go Green™ dealer for a free top off, it is fine to correct your tire pressure with regular compressed air for these normal and minor events without diminishing the benefits of your initial nitrogen fill.

If you have a "flat" tire or a situation where most or all of the nitrogen in your tire has been lost, you can also fill it with regular air if necessary, but we encourage you to visit your Go Green™ dealer as soon as possible to have the tire(s) purged and refilled with nitrogen so you can continue to enjoy the benefits it provides.

If you are a member of the Go Green™ Auto Club, most flat tires caused from road hazards, including tires damaged beyond repair, are covered, as is roadside assistance if your flat or damaged tire has left you stranded.

Will nitrogen improve the performance of the Tire Pressure Monitoring System on my vehicle?
Yes. Nitrogen will help maintain proper inflation in your tires and reduce the number of faults detected by the TPMS.

Do I still need to check tire pressure?
Yes. But, you will find the tire pressure to be more consistent, even during dramatic temperature changes.

Should I put nitrogen in my spare tire?
Absolutely! Your spare tire is the most neglected tire on your vehicle, and if you need it you certainly want it to be fully inflated. Because nitrogen dramatically slows the normal loss of pressure through permeation, your spare tire will hold its proper pressure over a much longer period of time than if it was filled with regular air.

Is nitrogen compatible with my internal tire balancing product [powder, beads, fluid]?
Absolutely, in fact, you couldn't find a better operating environment for an internal tire balancing product than a tire filled with nitrogen, due to its dry, inert qualities.

Is nitrogen a safety hazard?
No. Nitrogen is an inert, noncombustible, nonflammable, non-corrosive gas. In fact, those are big reasons why nitrogen is used to fill the tires of vehicles that push performance limits under extreme conditions, including Formula One racers and heavy machinery.
