abstract="A description is provided of a comprehensive program that was conducted by the U.S. Department of Agriculture, Forest Service, to evaluate the effectiveness of central tire inflation (CTI) systems in the transportation of forest products over unpaved low-volume roads. CTI is a mechanical component system for vehicles that allows the operator to adjust the inflation pressure of tires while the vehicle is in motion. The use of this system would allow tire pressure to be varied so that low-strength, low-speed roads could be negotiated with low tire pressures and higher-strength, higher-speed roads could be negotiated at higher tire pressures. A proof-of-concept test and a feasibility study indicated that the use of such systems on low-volume roads is technically and economically feasible. Such systems would provide considerable benefits to both the road agency and the road user in the form of lower costs for construction and maintenance, and lower operating costs and a reduction in driver fatigue, respectively. In 1986 the Forest Service initiated two controlled, quantitative tests on specifically designed and constructed test tracks to measure the effects of tire pressure on the road and the vehicle. A series of qualitative tests were simultaneously conducted on ongoing projects of logging operations and gravel hauling to ascertain and demonstrate the feasibility of using low tire pressures on low-volume roads.
