SUVs are supposed to be unsafe because of inferior handling... the main issue is center of gravity, but do the wheels have anything to do with it as well?

Do their wheels make it harder or easier to brake and turn?

Equations VERY appreciated!!!
 
Another thing that makes SUVs have inferior handling is the fact that they are higher off the ground than regular cars.

Whilst making sharp turns there are various forces acting on the SUV. In circular motion there is a force acting at exactly 90 degrees to the driving force( forward motion ), and this force is within the center of gravity. The height of the vehicle increases the turning moment between the force acting at 90 degrees and the ground.

The equations for turning moment:

M = f*d

f = force
d = distance

the larger the number the bigger the turning moment, if this number gets big enough the SUV will roll.
