Hi I am desperately searching for a tire model whithin which a dynamic rolling radius is applied based on magic formula. A tire model that I saw on Matlab pages has a fixed rolling radius at 0.3. That should be the nominal tire radius which is not totally what I am looking for. Can someone please suggest a tire model block for simulink that fulfill this requirement?
Thanks in advance

What do you mean by dynamic rolling radius? Do you want to change it during simulation runtime? As per the documentation, the default value of Unloaded tire-wheel radius is 0.3, that means you can change the value of the radius. But the radius will be a fixed value during the simulation.
