I'm not sure what point you are making, but the current camber thrust article doesn't even mention the "rolling cone" model, mostly for lack of reliable sources. As explained on that article talk page, neither "Cossalter nor Pacejka mention the cone analogy, and Foale concedes at the top of page 2-24 that the actual corner radius described is considerably greater than the cone radius." Thus, it is not mentioned here or in the bicycle and motorcycle dynamics article. -
