摘要：	The USDA Forest Service has been investigating the concept of using reduced tire pressures for over 14 years. Numerous structured tests and field demonstrations were conducted by the agency to determine the benefits, practicality and operational feasibility of lowering tire pressures on heavy vehicles. An eight year technology application plan ("Operation Bigfoot") was prepared in 1988 to guide testing, evaluation and development of Variable Tire Pressure (VTP) technology in the Forest Service. The conclusion of this exhaustive testing has revealed that use of VTP technology can dramatically reduce road development, operation and maintenance costs of gravel, native surfaced and thin-asphalt roads. In addition, use of VTP technology has shown to reduce traffic-induced road surface sediment from native and gravel surfaces by up to 85%. Use of an on-board Central Tire Inflation (CTI) system allows for the maximum ability for managing tire pressures to accommodate specific road surfaces. Commercially available CTI systems continuously monitor and adjust tire pressures to achieve maximum tread life. An emergency mode is available on these units that allow for temporary reduction of tire pressures to extremely low levels to facilitate mobility of a stuck vehicle. Awareness of the technology is increasing as public and private land management agencies look for ways to reduce road-related costs, protect the infrastructure investment, and reduce road surface sediment.
