The project identifies the importance of tire traction properties of truck tires in order to determine the steering and braking response of light and heavy commercial vehicles. Tire tests on a large sample of light and heavy truck tires were conducted using two laboratory and one over-the-road tire test device. A computerized simulation study providing a mechanistic understanding of the response sensitivity of the open-loop vehicle to tire properties was conducted. Full-scale vehicle tests permitted validation of the simulation as reinforcement to the basic findings obtained through computerized analysis. Findings of the study include significant differences in the qualitative performance characteristics of truck tires relative to passenger car tires, and the manner in which these unique truck tire properties may affect the yaw stability of the commercial vehicle. Potential problems of vehicle stability were illustrated by a rollover incident which occurred during testing of a heavy truck.
