The report documents an evaluation of the economic impact of potential truck tire noise regulations through analysis of the life cycle costs associated with the utilization of various types of truck tires in over-the-road motor carrier operations. The basis for the life cycle cost calculations is actual fleet tire wear rate data--including tire use location, rotation sequence, pull depth strategy, recapping practices, etc.--from twelve major long-haul carriers located throughout the nation. Comparison of the average cost per mile figures reveals that the radial rib tire use scenario is essentially equivalent economically to the bias-ply rib/bias-ply crossbar (current practice) scenario. Utilization of bias-ply rib tires at both steer and drive axle positions proves to be more costly. In addition to initial investment and replacement cost estimates, qualitative estimates of anticipated variation in maintenance, inventory and operating costs are made. Relative to bias-ply tires, radial tires have the potential for actually decreasing most of these cost factors. Assuming a reasonable lead time for the effective date of the regulation that would ensure the availability of adequate quantities of radial tires, total industry changeover to radial rib tires would have little economic impact.
