Can anyone tell me before I beat mysself silly-Looking for the biggest tire size/Offset I can put on my car with the stock spring set-up I have 10in drum brakes on the 8 3/4 rear end, I think I'm going to go with 15in tire size all the way around and I switched the car to big bolt pattern already and am looking at rims now-Thanks Swifter

Most I've been able to get in a stock Duster is:
Front - 235/60R15s on 15x7 4.50BS
Rear - 275/60R15 on 15x8 4.25BS
Slightly lowered nose
Stock springs & ride height rear
Tightest fit was at front of the rear wheelhouse/quarter flange. Spaced the rear spring hangers back with a .250 plate,
and trimmed the front fender bottom forward corner a bit, and no issues.
Filling up the wheelwells on those cars really changes their look. Here's a pic of the car...

You sure you didn't mean 15x7 with 4.25 backspace and 15x8 with 4.5 backspace. That what the repro rallyes are sold at. Unless you had them made up.

That's what I put on my 70. It has an 8-3/4" rear with B-body drums. With 275/60/15s I have 3/8" clearance to the spring.
