The rolling resistance coefficient is essential to assess the fuel efficiency of a tire. It is one of the three classifications needed for the EU Tire Label: fuel consumption, wet grip and noise emission. The EU tire labelling is having a higher impact thanks to the increasing e-commerce sales in the tire industry.
The inmess rolling resistance measuring machines are equipped with both torque and force rolling resistance measurement methods. Both methods have advantages that make them preferable (or less preferable) in specific situations. The inmess machines are a reference for known members of the European commission expert group in terms of laboratory alignment for the measurement of tire rolling resistance. The alignment of an inmess rolling resistance measuring machine is very achievable, the experts have always shown to be clearly impressed by the quality of the measurement accuracy.
