Rim Backspacing

[smallv6]

These are the tires I am getting
Back- 275 x 60 x 15 BFG Drag Radials
Front- 235 x 60 x15 BFG TA's
Rims- American Racing Outlaw 1
15 x 8
My question is what Backspacing do the rims have to have to ensure no rubbing.
Thanks in advance.

Rear BS should be close to 3-1/2. Don't know front BS

smallv6, you have exactly the same tire sizes as I do! The front wheels are the stock ones 15" X 7", so I would say 4" back spacing, as for the rear wheels 15" X 8", you want NO MORE that 3 1/2" back spacing!!! More than that for the rear wheels, and you will have to go to different kinds of shims, or wheel spacers which are a "plaster" for those who didn't get wheels with the correct offset in the first place!!!
