Consumer & Fleet Benefits

• Better Fuel Economy

Up to 6% increase in fuel mileage.  With the average gas price of $2.50 gal, it hardly needs to be mentioned that any fuel savings increase is a major selling point for Nitrogen. For Fleet owners, it simply means more money in the pocket in OTR miles.


• Longer Tire Life

Up to 30% longer tire life. This is an extremely important consideration for the consumer, it takes about 7 gallons of oil to make one average passenger car tire, 15 gallons for a Fleet tire, and with the price of oil approaching $60.00 / barrel, the cost of replacement tires will rise with the cost of oil. For Fleet owners, Nitrogen will keep the inner liner supple and flexible over the 200,000+ miles you put on these long-haul tires, which keeps it from cracking and leaking.



• No internal Wheel Corrosion

Nitrogen filled tires contain no moisture that corrodes popular, and expensive, custom alloy and aluminum wheels that results in rim leaks and valve stem leaks. In Fleet tires, this steel corrosion cause dust which gets into the valve core mechanism and causes leaks.



• Improved Safety

Reduces internal tire integrity decomposition.   With more consistent tire pressure, tires will not overheat and cause premature tire failure.   Filling with Nitrogen will drastically reduce the risk of low tire pressure, which can cause vehicle rollover accidents in SUV's.
In Fleet tires, a catastophic tire failure can result in an explosion and fire from the excessive heat and presence of oxygen in the tire, which supports combustion. Nitrogen is an inert gas, and does not support combustion.



• Consistent Tire Pressure for TPMS Systems

All passenger vehicles will be required to have on-board TPMS (Tire Pressure Monitoring Systems) by 2008. Standard air-filled tires have been proven to cause excessive TPMS alarms, due to the rapid expansive properties of moisture-filled air. Using Nitrogen in tires monitored with TPMS systems will result in even tire pressure, and drastically reduce these annoying alarms.



• For Fleets, Nitrogen eliminates "clumping", a problem associated with tire balancing powders.

Tire balancing powders have a common problem when moisture is present in the tires of large trucks. This moisture collects on the many irregular surfaces of the powder granules and due to surface tension, causes these granules to stick together, and form a "clump", which destroys the balancing effectiveness. Nitrogen eliminates any moisture, and as a result, the balancing powder stays dry, and effective. This is especially important for truckers in the Northern latitudes, where below-freezing temperatures will freeze this "clump" into a solid mass which can damage the inner liner as it flies around inside.

Calculating your Return On Investment ( R.O.I )

R.O.I (in days) = Cost of N2 Unit / ( (Charge per Tire x Tires per Vehicle) x Vehicles per Day)

Example using:

• N20808-PG = $6478.00
• Charge per Tire = $5.00
• Tires per Vehicle = 4
• Vehicles per Day = 10

R.O.I. = $6478 / ( ( $5.00 x 4 ) x 10 )
R.O.I = 33 Days to pay for your Nitrogen Unit!!

How to select the proper size Nitrogen Generator

• On your busiest day of the week, at your busiest time of the year, estimate the maximum amount of tires that you expect to completely drain and/or fill with Nitrogen. This figure would be for the entire shop, whether you have 1 service bay or 15.

In the Northern States, for example, the busiest period for passenger vehicles is usually 48 hours before the first major snow storm of the year, and the next two weeks after.


• Add 20% growth after a successful ad campaign for Nitrogen. (passenger vehicles)


• Divide this figure by the number of hours in your workday to get a TPH, or Tires per Hour.


• Consult the chart below to see which model fits your Tires per Hour rate.
