205/60/16 or 215/55/16.
I used to run 225/55/16 tires on my Ford Contour with SVT wheels,and also 225/55/16's on my Catera.
Sorta crappy pic,but this shows the 225/55/16's profile.
Probably a better pic
Just an idea. You can fit up to a 235 wide tire with no issues,as stock 4x4's run 235/75/15 tires.
