Hi Jim,
I believe most of the guys measure the ride height from the centre of the wheel caps up to the lip of the fender, which puts us all on the same page and would negate tire sizes, tire pressure, etc.
If I remember correctly, mine is 13.25 inches in front and 13 at the rear. Others will soon chime in.

NB. I have checked my measurements and amended my post above.
