To help little bit i can tell you that on the straight car with the rear axle centered you can put on :
15x8 with BS 4,5 inch then tires 275/60 perferct fit, 255/60 no problem justy little lower and to narrow for my taste, 295/50 bigest meat you can put on, little rubbing on inside edge of fender, depends on your fenders, but it is an issue of about 1- 2 mm( can also happen it will not rube at all)
15x10 with BS 5,5 inch, you can have clearance issue with tire touching the leaf spring, but 275/60 should fit just fine ( no guarantee thogh )
