A tyre testing system was developed for the quantitative investigations of fundamental tyre properties. This system consists of a driving car, a measuring device of forces which act on tyre and a data acquisition device. The measuring device of forces which was manufactured for this paper is a calculating type; so it is desirable that the data acquisition device also should have calculating ability.　For that reason, a micro-computer system (CPU:μPD8080A), which consists of DC amprifiers, an AD converter　and data logging memory, was employed for the data acquisition device.　As a result of performance tests, it became clear that the measuring system satisfies the fundamental requirements,　and is able to sample simultaneous data of six channels with the sampling rate of 256(Hz).　It was also ascertained that the effect of velocity should be considered in the measurment of force acting on tyre in　case of dry sand road, unlike the case of hard surface road.
