THE NOISE AND TRACTION CHARACTERISTICS OF BIAS-PLY TRUCK TIRES. VOLUME 2. WET TRACTION FINDINGS

The project has established a data base of noise and traction characteristics for a sample of bias-ply heavy truck tires. The tire sample, representing both 'rib' and 'lug' type tread patterns, was tested according to the SAE J-57 tire noise procedure and in a variety of laboratory and over-the-road traction experiments. Dry-pavement traction results show that the noisier lug-type tires exhibit traction properties which are generally less desirable from the viewpoint of their influence on vehicle response to steering and braking. Wet traction results illustrate that the differences in braking traction between lug- and rib-type tires are even more discriminatory than on dry surfaces.
