235/60/15 on front of duster?
I missed that he was talking about an 8" wheel. Mine were on 7" wheels.
After the multiple calculations to convert backspacing to offset (sorry, minor :poke: at someone who shall remain un-named), that tire is going to be at least 3/4" further out than mine were, and that is without including the extra width the 235 is going to have on an 8" rim compared to a 7" rim.
I think Blu is right on the money. Assuming BBP (like mine), really doubt you will get those tires and rims to work on the front.
