Rolling Resistance Machine

  • Axial force method and torque method are in same test and keep excellent data consistency

  • Open calibration function, self-calibration, greatly reducing maintenance costs

  • High-performance data acquisition system

  • Passenger, Truck, Motor Cycle, Bike multiple models to choose

  • American DOT, NHTSA standard machine

  • Rolling Resistance Machine

  • Meet all industry test standards

  • Excellent equipment repeatability, σ≤0.05N/kN

TMSI’s Tire Rolling Resistance Test System, for one or two stations, provides highest quality measurements in  tire rolling resistance testing according to ISO 28580, ISO 18164, SAE J1269, SAE J2452, and any

other standards predefined by the customer. All of the measurements are performed by either the “Force” method, the “Torque” method, and the “Coast Down” method. The system can perform testing for passenger car, light truck, and commercial truck tires, with a single station or a two station configuration. The system is guaranteed to exceed the repeatability requirements of a reference system as defined in ISO 28580.
