15" Rear tire sizes for Duster

I'm wondering the same for my demon. I got a set of 275/60/15s for the rear and they look huge! Hopefully they will fit.

They'll fit. I had a set of 275/40/17's on my Duster with the stock 7.25" rear axle and stock spring location. If you have the stock 8 3/4, you should be good with a set of 15x8's with 4.5" backspace.
