True about the use of the ramps, but it is also true that lower tire pressures tend to decrease the propensity for the vehicle to tip over. The trick is a lot easier to initiate if the tires are that hard! But not quite true about about max FE not taking you near a car's tip over point. That's not the point. Accidents happen and sometimes vehicles tip over - even low slung sports cars - and overinflated tires help the vehicle to tip over once its started.
