15 X 8 with 5.5 bs will work good too...just depends how much you want the tire to tuck.

I have a set of Pro Stars for sale exactly what you need. They are 15x8 drilled for screws and garage kept always so they look good.
$250.00 let me know.

I have 15 x 10's with 5.5 backspace. With 275 50 15 tires I have about an inch of clearance on the back and the tires are about 3/8 inch inside the widest point of the fender.

BTW, the wheels in my sig are not the ones on the car now. Those were 15 x 10 with 3 or 3.5 backspace and stuck out about 2 inches.

15x8 with 5.5" backspacing looks perfect in my opinion... I run 27x10.5" Hoosier QTP's on mine and they tuck perfectly. I'm sure I could fit a 27x11.5" QTP just fine too
