ABSTRACT:
A procedure and apparatus for determining the characteristic values of tires and rims and/or the attitude of the endurance limit of the same by rolling a wheel on a drum drive machine and measuring the forces and/or moments with a torque indicator. The measured forces are then transformed to the forces at the area of contact between the wheel and the drum. The forces applied to the wheel may then be readjusted by altering the slip angle, the camber angle and/or the contact pressure of the wheel on the drum.
