89 ranger choosing wheels with explorer rear end.

[1bad87five0ranger]

I have a first gen ranger with a full length explorer rear end. It is dropped 4'' in the rear and i am running 16x8 cobra r replicas with 255/60's. I have around 2.5'' between the top of fender well and the tire. Im afraid it is gonna hit. I need some suggestions on wheels and tire size. can someone help me with backspacing so i can get them tucked under the fenders again. I am wanting some torque thrust or 05-07 mustang bullit wheels but i need to know the offset to run. All help will be greatly appreciated.
