15 X 3.5" fronts. No backspace. You will have to use a spacer 7/16" and grind the caliper fins.

15 X 10" rears, 7.5" backspace. I use a spacer back there also.

Longer wheel studs and weld's extra length shank nuts are very good ideas also.

For the front(with 12" rotors) Weld ProStar in the 15 x 3.5 size with a 165/85R15 tire, for the rear Weld ProStar 15 x 10 with 7.5" backspacing and a 5/16 spacer with a 275/50R15 tire.

These size tires are the closest to duplicating the stock tire diameter.
Don't forget longer studs(68mm) and the proper lugnuts.

If you have J55 brakes, you may need a spacer for the front, I believe it's 5/16 as well.
