Truck/Bus Rolling Resistance Tire Tester

Truck/Bus Rolling Resistance Tire Tester
About the Rolling Resistance Tester
This machine uses the torque method to measure rolling resistance, under controlled laboratory conditions, for new truck/bus tires. It correlates measurement results to enable inter-laboratory comparisons.
 
Add the optional camber unit to compare rolling resistance from tires, free-rolling straight ahead, to a steady-state tire with camber in a position that is perpendicular to the drum outer surface. 
 
SAE: J2425   ISO: 28580 Rolling Resistance Standard
 
For Single point test and correlation of measurement results
