From the results of experiments conducted at the Vehicle Research Laboratory, Delft, Netherlands, two test trailers for measuring tire characteristics are described. One of the trailers is specially built for testing car tires and can steer, camber, and brake the test tire. This trailer is provided with a five component measuring hub. The second trailer, for testing truck tires, is restricted to braking only. Braking forces are measured with a dynamometer. The determination of peak and locked wheel braking force coefficients is discussed. In addition, for car tires, a method for obtaining side force coefficients is given. Test results are given and compared for both car and truck tires showing the influence of road surface texture, speed, and tread depth on skid resistance. /DOT/
