Hot Rods Trying to fill the rear fender well of my Studebaker M5

This truck had racing slicks 28 x 12 x 15 on 15 x 10 wheels that tucked up inside the fender. The slicks sidewalls bulged to 14 inches. Wheels and slicks are gone. I want the same look without the slicks. Or as close as I can come. I think my problem is pushing the tire out to the fender?

A) mounting surface to first obstruction = 6 3/4
B) mounting surface to fender edge= 11 1/2
C) hub dia = 2.47
D) center of hub to top of caliper x 2 = 13
E) caliper doesn't protrude past mounting surface

rotors are 11"
current tires are 265x70x15

 

Your rear end is narrowed and the thing is tubbed pretty good.
You run with that and something from micky Thompson sportsman series tires on team 3 wheels. Should get you close to the same arrangements and sizes.
Told you the same in your other thread. You'll not get there from the corner tire store.
Cost you around 2000 all said and done ordering exactly what you need in new stuff. Hunt the swap meets for used stuff you can make work.
Also take a look at trick 8 wheels. Probably won't be enough but look and measure anyways

 

To bad the wheels are gone now. To have taken specs from them before hand would have helped you now.

 

How's the backspacing look on the current rim/tire ? It shouldn't be to hard to figure out just add/subtract backspacing and offset on the current rims, you already know the tire dimension and rim width that worked before.

 

Previous back space was 3.5".
