Rear Duster Tire Size

Duster came with G50-14 on 14x8s..........Those tires were dry rotted and the wheels were actually both bent

I found some 14 x 6 aluminum slots with 3-3/8" backspacing for my SBP rear 8-3/4" axle

I know the backspacing is not ideal for the car but it's what I am working with

With the wheel mounted on the car and two lugs installed to hold it secure, I did some measuring:

I have about 2-1/2" of room from the leaf springs to the back edge lip of the wheel

I have about 3-1/2" of room from the inner wheel well to the back edge lip of the wheel

I have about 1-3/4" of room to the outside of the rear fender to the outer/front edge lip of the wheel

I have about 1/2" of room from a lip on the rear fender to the outer/front edge lip of the wheel

Again, not an ideal wheel to run but its what I have found to match my front SBP aluminum slots

With all this being said, what size 14" rear tires can I run? Should I make sure the tire fits inside the rear fender wheel well opening?

Or, is it ok to run a wider tire that may stick out? I was concerned about body and tire damage with suspension movement

Here is how wide the rear tire was when I bought the car, with the G50-14 and the 14x8s with 3-1/2" backspacing
