Shorter/taller tires also affect the roll center(s), scrub radius, etc. ...
sometimes this can be helpful and sometimes it screws things up, depending
upon the car, its intended use, etc.  I'd make a sketch to show this but I
think it'd be virtually impossible to do in ASCII given the small
differences involved...
