RE: Tire force combining review
Well, that was a waste of time...
I've implemented a 4 tread model (think of 4 narrow tires instead of a wide one), with vertical deflection, contact length and velocity calculated per tread depending on wheel camber.
To my surprise the force curves are pretty much the same, deviate only slightly from the single tread tire model.
Contact patch deformation doesn't seem to have much effect (deformation at max fy, shorter contact side has 0.14m and longer side 0.20m length).
It might be that the model is too simple in general, using a constant average contact pressure and a few other simplifications.
