In this paper we report on an experimental investigation on the friction of tire tread sections sliding over a variety of surfaces. The Texas A&M friction tester was used to measure sliding friction at various speeds and contact pressures. The friction test machine is also described. Actual bituminous and concrete road pavements and artificial 3M Safety Walk were used as surface samples. Tread rubber sections taken from passenger car, truck, and aircraft tires were tested. The influence of major test parameters such as sliding speed, surface texture and contact pressure on friction are discussed.
