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.
SAE: J2425 ISO: 28580 Rolling Resistance Standard
