I notice that the second sentence of the Meijaard et al paper says that 
their simulation does indeed specify knife-edge contact:
“The wheels are also axisymmetric and make ideal knife-edge rolling 
point-contact with the level ground.”

Very interesting.

Good separation of variables approach.

They are using the 'Steering into Fall' effect which follows from
tire cross-section (IIUC).

I'd like to see the effect of a 'knife-edge' tire with each of the
other effects included/excluded.

Other effects being gyro and trail.
