A mobile test station has demonstrated its effectiveness in measuring straight-ahead traction coefficients of truck tires. This system - incorporated into a modified trailer-tractor combination - is designed to test the entire range of light-truck and heavy-truck tires now in production. The tire carriage assembly is installed in the center of the flat-bed trailer. The tire is hydraulically loaded to the ground through an opening in the bed. To ensure reasonably valid tire-traction data, the system is designed to minimize variations in such test parameters as load, brake line pressure, vehicle speed, and tire orientation.
