Nitrogen-Filled Tires
Facts & Testimonials

“One thing government and tire-industry officials agree on is the importance of keeping tires properly inflated.  The risks of underinflation, which stresses tires by causing their sidewalls to flex more and the air temperature inside to rise, were highlighted during congressional hearings a few years ago.  Underinflation was identified as a factor in the failure of these tires.”      Wall Street Journal, September 25, 2002

Using nitrogen instead of compressed air has distinct advantages which lead to immediate benefits for the vehicle owner.

  1.  It has more mass so it migrates through the tire three to four times slower.  The result: Tires hold their psi
       longer.
  2.  It runs about 20% cooler.  Less heat results in less tire degradation.
  3.  It drastically reduces oxidation on the rim and inner liner (nitrogen systems almost totally eliminate        oxygen    the cause of oxidation   from the mix).
  4.  It is enviromentally safe
             Bob Ulirich, Modern Tire Dealer, July, 2004

United States Department of Energy says the United States loses over 2 million gallons of juel each day dur to under inflation.

FREQUENTLY ASK QUESTIONS

QUESTION:
Regular air-filled tires already contain about 78% nitrogen.  Why does the extra amount of nitrogen make such a big difference in tires?
ANSWER:
There are three distinct factors at work here.  First, the extra percentage of nitrogen (93% to 95%) makes a significant difference in maintaining consistent tire pressure simply because the nitrogen molecule is larger in size than the oxygen molecule and migrates out of semi-porous materials (rubber tires) at slower rates than do oxygen molecules.  Studies have shown when a tire is inflated with a minimum of 93& nitrogen, the tire manintains its pressure three-to-four times longer than when regular air is utilized.

Second, oxygen is a corrosion initiator and supports combustion.  Both of these qualities make oxygen a poor tire inflation gas.  The presence of oxygen is particularly harmful in high pressure and high moisture content environments such as the interior of a tire.  So the goal is to minimize the content of oxygen and moisture to prevent interior wheel corrosion which impacts a tire’s ability to properly sit on the rim and provide a consistent,tight seal.  This is becoming a significant issue today especially with the increase in alloy wheel popularity.  Nitrogen is an inert gas so it is non-corroswive, and nitrogen does not support combustion..

Third, on-demand nitrogen generation requires a moisture-free air source.  All NitroPRO Nitrogen Tire Inflation Systems “ultra-scrub” water moisture from the input air source.  This results in generated  nitrogen that is at minimum 99.9% moisture- free.  The absence of water vapor in a near-nitrogen pure environment helps to stabilize interior tire pressure when the tire exterior is subjected to large temperature differentials.

 This is why nitrogen makes the big difference!

QUESTION:

How is using nitrogen in tires good for the enviroment?

ANSWER:

Because tires stay properly inflated for a longer period of time with nitrogen filling, cars get better gas mileage and use less fuel.  Less fuel burned tgranslated into lower emissions introduced to the enviroment.  Additionally, tires wear much longer when consistentley and properly inflated, and thus longer-life tires reduce the demand for oil and other raw materials as well.

QUESTION:

Why doesn’t the purity level in the tire exactly match the stated purity level of the NTF machine after a service?

ANSWER:

All NTF series machines are factory preset to generate 95% nitrogen at the membrane outlet in front of the unit reservoir. Since both the machine reservoir and the vehicle tires always contain residual amounts of ambient air, the total overall nitrogen purity level will register slightly lower in the reservoir and agaqin slightly lower in the tire because of residual air dilution.  vacuuming air out ot the tir3e before nitrogen inflation     or the process of deflating, nitrogen filling, purging, and nitrogen re-filling     helps to minimize the dilution affect, but some dilution will always be present. 

The only way to completely eliminate the dilution impact of ambient air in the nitrogen inflation process would be to draw a perfect vacuum throughout the entire fill system (fill lines, reservoir, and tire) and then fill with 100% pure nitrogen.  However, this is not practical and, of course, is not necessary because 93% nitrogen purity in the vehicle’s tire is all that is necessary to9 produce the desired benefits of nitrogen tire inflation.

QUESTION:

Do tire manufacturers void warranty when their tires are inflated with nitrogen?

ANSWER:

 No!  Tires are sill covered under a tire manufacturer’s warranty when a customer uses nitrogen as the inflation gas.

QUESTION:

What is my tire develops a flat or has a slow leak and nitrogen is not available where I am?

ANSWER:

Topping off a nitrogen-inflated tire with regular compressed air is acceptable in these circumstances.  Naturally since you made the investment to convert to nitrogen inflation we recommend the subject tire be “nitrogen-serviced” as soon as possible to resume the beneficial impact nitrogen has on the vehicle.

QUESTION:

Does nitrogen inflation affect the accuracy of tire pressure monitoring systems now being installed as standard equipment on some cars?

ANSWER:

No!  Nitrogen inflation gas has no detrimental affect on TPMS sensors because the sensor is reacting to the pressure level of the inflation gas within the tire.  We continually receive reports that vehicles equipped with TPMS and running nitrogen tire inflation have had dramatically fewer issues with false signals from such systems because the nitrogen gas now contained inside the tire is virtually moisture-free. (Moisture contained in regular air dramatically affects pressure and temperature stability inside tires.)  The TPMS low-pressure indicator light should not be illuminated if a vehicle’s tires are properly inflated with nitrogen to the manufacturer’s recommended specification usless the TPMS is malfunctioning.
