the loss of energy by conversion to heat in a system exhibiting hysteresis.
In general, coercivity and hysteresis loss increase whereas permeability decreases with plastic deformation.
In order to decrease the rolling resistance on a smooth surface, the material of the tire must have a low hysteresis loss.
Hysteresis loss can be reduced by using improved steels and by reducing the intensity of the magnetic field.
Low mechanical hysteresis loss in the tread is desirable, since lower tire operating temperatures are advantageous.
