The distance (r) of the centerline of the wheel (1) hub (4) from the road surface (5) gives the effective rolling radius which varies with deformation of the tire (3). The hub height sensor (6) is connected to a control circuit (7) with a wheel rev counter (8). It is connected to a tachometer (9) and a digital distance display (10), also a visual monitor display (11). |
