Sorry I'm not buying that. Popping a tire off it's bead requires extraordinary force, I've done it at rallycrosses where the tires are slammed sideways into sand. The tires you speak of will simply slide on pavement unless they are horribly underinflated, but I don't think that that element falls within the scope of our discussion. Additionally a bare wheel will have an even lower coefficient of friction on pavement than the tire would. It would have to be some really soft asphalt for it to dig in and trip up the car. Unless you've extended the scope to off pavement situations. I think that Jesse and I were trying to limit the discussion to the aspects of a car that can lead to a high flip tendancy.

It may be reasonable to consider off pavement excursions as they do occur at autocrosses. Off the pavement, the terrain plays a greater role in determining flip probability. Relatively soft terrain allows for the possibility that a car's tires could dig in while it's sliding sideways, this can trip the car into a roll. If there are low immovable objects in the terrain, tree stumps, curbs etc. they can trip up a car too. In such situations your best bet is to have a long wide car with a really low CG.
