18" Wheel help

Mustang AMR Charcoal Wheel; 18x9; 30mm Offset (05-09 Mustang) - Free Shipping

These are only 8" wide but would they work for the front and rear being 30mm offset?
I would still prefer a bigger tire in the rear but really like the wheels.

Uh, they have 18x9's in the same wheel with a 30mm offset as well.

The 18x8's in a +30 would fit the front and rear, but you'd be limited on tire width to a 245 with the 8" wheel. Of course if you go to the 18x9" +30 you'd need spacers in the rear with the A-body width rear end.
