<p>An apparatus (10) and method of operating a rolling wheel testing apparatus (10) includes driving a tire and wheel assembly (14) about an axis of rotation with a tire (20) in rolling contact with a rotatable drum (16). Torque is sensed about the axis of rotation and rotation of the drum (16) is inhibited so as to develop a selected amount of torque about the axis of rotation as the tire and wheel assembly (14) is rotated.</p> |
