Performing well under pressure Jan 1, 2006 12:00 PM By far, the
single most critical factor for maximizing tire life and
minimizing the chance of tire failure is maintaining proper
inflation pressure. One way to help maintain proper tire
inflation is to fill tires with nitrogen instead of compressed
air. Nitrogen allows a tire to retain more of its original
properties. Among the benefits of nitrogen inflation: less
inflation pressure loss for a more stable, consistent tire
pressure; cooler running tires; longer tread life; less
oxidation of tire components; and less rim and wheel corrosion.
The result is increased tire life, improved fuel economy,
reduced tire aging, and a more durable casing. While the trend
toward nitrogen inflation is relatively new to the truck and bus
tire market, it has been long used in tires on Formula One,
Indy, Le Mans, and NASCAR racecars; commercial and military
aircraft; military vehicles; heavy off-road construction
equipment, and the space shuttle. A reason for the slow growth
