Rolling resistance is the force resisting the motion of a tyre rolling over a surface, rider power is required to overcome this force.

The Rolling Resistance Rig utilises a motor driven roller, contained within an enclosure to rotate a wheel; vertical mass can be applied to simulate the tyre contact patch load. Using measurements from a torque meter, the rolling resistance is then quantified by comparing the power required to drive the roller at a constant rotational speed, with and without tyre in contact, thus the power required to rotate the wheel is then calculated.

The rig can measure marginal differences in power and can be used for the comparison of test samples or to investigate variables such as wheel speed, contact patch load and tyre pressures.

If you want to be one of the first to see how this rig can benefit your company, then please register your interest at either or call us on 01327 222 830.
