The Hasbach Division RRT tests for SAE: J2425 ISO: 28580 Rolling Resistance Standard
The Hasbach Division lab testers come in single station or multiple station designs. Multiple Station Machines use one loadwheel to test more than one tire / size at the same time.
This machine uses the torque method to measure rolling resistance, under controlled laboratory conditions, for new passenger / light truck pneumatic 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.
For Single point test and correlation of measurement results
* Mandatory guard rails not pictured in
photography to show machine details
* Machine is CE Certified
