New Nitrogen Inflation System Reduces Tire Maintenance Costs, Improves Tire Life

2006-04-17 16:36:08

ORLANDO, Fla., April 17, 2006 - Vehicle Inspection Systems Inc. (VIS) has introduced a high-performance nitrogen tire inflation system called VIS-Nitro that can help fleet operators reduce maintenance costs and improve tire life.

"VIS-Nitro is a nitrogen inflation system with a big difference, it's fully automated," said Miles Fuller, president of VIS. "An inflation controller on VIS-Nitro automates tire top-ups, eliminates the need for handheld pressure gauges, improves inflation accuracy and can fill four commercial tires simultaneously. All the technician has to do is clip the four chucks on, set the pressure and walk away. The machine beeps when it's done, making the operation completely hands-off. It also has an automated purge cycle that vents air from within an inflated tire and replaces it with high purity nitrogen produced by VIS-Nitro."

Studies show that tires filled with nitrogen retain pressure better than those filled with air. When tires are filled with compressed air, it migrates through the rubber of the tire. Depending on the quality of the tire brand, tires can lose more than 2 psi per month as a result of air passing through the sidewalls. Oxygen and water vapor in compressed air can also corrode aluminum and steel wheels, rust the tire's steel cords, and react to the tire components, making the tire more susceptible to even greater pressure loss. Nitrogen, with its larger molecules, permeates through rubber more slowly and is far less corrosive than compressed air. It maintains tire pressure longer, reduces the risk of blowouts by overheating and lengthens tread life and retreadability by preventing rubber oxidation,

Under inflation is the leading cause of premature tire wear. At normal speeds, running tires 20 percent below recommended pressure reduces tire mileage by 16 percent and fuel mileage by 2 percent. Each year, under-inflated tires cost fleet operators millions of dollars in wasted fuel, premature tire failures, and costly downtime.

Steve Motta, VIS market development manager, said by automating the inflation top-up procedure and using nitrogen instead of compressed air to complete the task, VIS-Nitro has eliminated what makes the task unpleasant, improved its speed, accuracy and effectiveness, and increased the time between inflation top-ups.

"That's how fleets will see lower maintenance costs, extended tire life and improved retread ability with VIS-Nitro," he added.

The company will demonstrate VIS-Nitro's inflation automation capabilities by performing an air purge and nitrogen inflation on four truck tires simultaneously at the American Truck Dealer Conference and Exhibition, April 22-24, in Atlanta, Ga.
