235/60/15 on front of duster?

Here's a post were @autoxcuda said max backspacing on a 15" rim is 4.5" with a stock UCA.

73-76 A-Body Offset

That would push the tire in another 1/4" from where mine ended up.

So maybe a 15x7 with 4.5" BS would work?

One thing you could try is one of those online calculators and plug in a know wheel and tire combo on your car and then the new sizes and see how it moves the tire around. Based on that you could get an idea of how well it might fit.

a 15x7 with 4.5 backspacing is most likely going to be a custom spec rim.

I run 15x8 with 4.5 backspacing BUT with much smaller diameter 245/50/15 tire.

with 235/60/15, 15x7, 4.5” backspace, and BBP disks is going to be real close. So close that alignment settings and component parts will create variation between to same model where one rub and one doesn’t.

Probably need bottom fender support moved out. Might need fender lipping.

just too close to call. You’re on your own to use methods to overcome what you end up with.
