The friction torque, C, of drum bearings can also be measured provided that the rope can be separated from the drum once mass, m, has given sufficient momentum to the drum, for the subsequent drum deceleration is directly related to C by: In measuring tyre rolling resistance, it is necessary to measure small forces in iso 18164 presence of much larger forces, it is, therefore, essential that equipment and instrumentation of appropriate accuracy be used.


Depending upon the circumstances of particular tyre applications, it can be useful iso 18164 determine the effect of these tyre-related parameters ixo the individual tyre to be tested.

This measured value also includes the bearing losses of the tyre spindle and the aerodynamic losses of the tyre and the wheel. Such a break-in shall be carried out on a test drum of at least 1 ,5 m diameter 1 ,7 m for truck 181644 bus tyres for a period of at least 1 h, at a minimum iso 18164 as given in 6.
