THE INFLUENCE OF CENTRAL TIRE INFLATION (CTI) ON ROAD LIFE AND VEHICLE STABILITY

Central Tire Inflation (CTI) systems allow a vehicle operator to change the tire inflation pressure while the vehicle is moving. Lower tire inflation pressure has been found to reduce road wear and improve vehicle performance in areas of traction, braking, ride quality and vehicle maintenance. The benefits of lower tire pressure on road systems have been reported in various publications and reports, however the influence of lower tire pressures (higher tire deflection) on stability and control of heavy vehicles is not well understood. This paper summarizes the significant CTI research findings with respect to the infrastructure and explores the effects of CTI on vehicle stability and control performance. The analysis focused on a 9 axle B-train in the loaded state assuming GVW of 75,500 kg, and 69,000 kg; and in the empty state.
