The tire radius which relates the torque and circumferential force is rolling radius in the driven mode [r.
This kinematic discrepancy arises from the different values of the rolling radius in the driven mode [r'(").

The user will set information on the tyres from the Pneus ('Tyres') tab (Figure 3b): tyre type (radial or bias ply); number of tyres by axles; tyres section width; tyres overall diameter; rim diameter, and rolling radius of tyres.
This way the local rolling radius in each point on the wheel profile is R(t) = [R.
However, such angles of attack will only occur in very tight curves so that the difference in rolling radius between the left and right wheel will not compensate for the difference in traveled distance on the left and right rail; therefore in such cases there will always be a high longitudinal creep force so that the change in moment due to the longitudinal contact location can safely be neglected.
The module's optional features let users control how tire slip and rolling radius are calculated and include tire transients through differential equations.
A series of wheel-speed sensors including both magnetic-generating and semiconductor types by Sumitomo Electric and a tire-deflation warning system that detects 20 percent deflation levels under normal drix4ng conditions; the system measures tire rolling radius to determine deflation levels.
The XLD 70 has a smaller rolling radius (rolling radius = rolling circumference/2[Pi]) than the series 80 tyre with the same loading capacity.
where r is the rolling radius of wheel, n denote the recovery coefficient of tire, R represent [R.
