Duster - Suspension/Wheel/Tire Combo Question

'73 Duster, cloned to a '71 (tail panel, front clip), 7 1/4 rear end: You can fit 295/50/15 on the rear, as pictured here. Not sure of the backspacing that the rims had though. Tires would only rub if they bottomed out going up into the curve of the fender well (if you get what I am meaning to say...lol). Had air shocks on rear to stiffin' it in the rear to prevent it from bottoming out on bumps with a load (2 people) in back.......so, you can fit up to a 295 with minimum rub issues.
