Oxygen readily permeates or leaks through the body of your tires resulting in low tire pressure. Because NitroFill is an inert dry gas, it prevents rust, rot and corrosion from occurring. And due to its large molecular structure, it won’t seep through your tires like regular air does. Properly inflated, oxygen-free tires last much longer and perform better.
Compressed air is your tire’s worst enemy. Air is about 78% nitrogen, 21% oxygen, and 1% other. Nitrogen is inert, noncombustible 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.
No, the purity of nitrogen available from nitrogen generators generally ranges from 95% (low purity) to 99.9% (high purity). NitroFill generators can produce nitrogen in excess of 99.9% purity and are programmed to provide a guaranteed minimum of 95% purity in the serviced tire, which is the minimum allowable purity that must be maintained in the tire to enjoy the benefits of nitrogen inflation. Few generator manufacturers currently discuss this mandatory 95% threshold, as few are able to consistently provide the required purity to achieve it.

Low tire pressure is generally due to one of the following three conditions:
A leak. Most tire leaks are the result of a hole or puncture, faulty valve, or a porous or corroded wheel.
Permeation. Permeation is the normal process by which the oxygen in air bleeds through a tire’s body or carcass. It is typical for an “air" filled tire to lose 1-3 psi of pressure every month through normal permeation whereas it can take several months for a NitroFilled tire to lose a single pound of pressure.
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 NitroFill dealers will always check and correct your tire pressure with NitroFill 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 NitroFill 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 NitroFill dealer for a free top off, you can correct your tire pressure with regular compressed air for these normal and minor events without diminishing the benefits of nitrogen inflation.
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 NitroFill dealer as soon as possible to have the tire(s) purged and refilled with NitroFill so you can continue to enjoy the benefits this product provides.
If you are a member of the NitroFill Motor 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.
All new cars and trucks, and most vehicles manufactured after 2005, are equipped with Tire Pressure Monitoring Systems (TPMS). TPMS’s were mandated by the federal government in an attempt to address the many detrimental effects of a nation of under inflated tires. Tire Pressure Monitoring Systems typically consist of sensing devices mounted inside of each tire on a so equipped vehicle that signal a receiver inside the cabin, illuminating a warning light on the dashboard whenever the tire pressure in any tire drops below a pre-established level. While well intended, TPMS systems can do more harm than good and create a false sense of security. Our main gripe with these systems is that the government mandate only requires the driver to be warned when the tire pressure drops to a level that is 25% below the manufacturer’s recommended pressure value. In other words, a tire can lose up to 25% of its pressure before the system warns you. For example, a tire that should be inflated to 30 psi can drop all the way to 22 psi before the driver is warned that the tire pressure is low. This is a critical flaw in these systems as it only takes a few pounds to seriously affect the safety and performance of a tire…and your pocketbook. Just remember: while an illuminated “Check Tire" light is probably a sure indication that you have an underinflated tire, a non-illuminated light DOES NOT indicate your tires are properly inflated.
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 NitroFill 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.
No. Nitrogen is an inert, noncombustible, nonflammable, non-corrosive gas. In fact, these are some of the key 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.
