Effect of Vehicle Maintenance

This paper points out that some of the most important factors causing reduction in tire mileage are the increase of horsepower, speed, and torque of modern tractors and trucks as compared to those in popular use 7 to 10 years ago. The importance of maintenance to the vehicle toward the end of reducing tire costs to a minimum is emphasized. These factors include front wheel alignment and loading, wheel and tire assembly concentricity, lateral and radial runout, balance, drive and trailer axle alignment problems, suspension maintenance problems; wide-spread axle operation, tag axles, shock absorbers, warning systems, brakes, wheel bearings, belts, and seals.
