Re: 15 x 8 rallys w/ 6" bs

Yes in the back.
No in the front.

I have a set of 15x8's with 5" BS.
They won't work up front.

Any 15" wheel with over 3.5" of backspacing will require grinding of the lower a-arm.
I think 4" BS is the max.

You can get away with that much backspacing with larger diameter wheels (20's),... but not with 15's.

They might work on the front without drop spindles...

I think they will hit the lower control arm when you turn.

Re: 15 x 8 rallys w/ 6" bs

Agreed. Also will be close to the inners out back. Overall, I'd say the 6" BS is risky at best...

Are those 15x7 or 15x8 on the rear on the above truck?
