68 Cuda-largest tire help please ......

Ok guys .......
68 Cuda Fastback, mini tubbed , inboard spring relocation kit . SS springs. Dana 60 .
The Cuda gets Mini tubbed in a few weeks , The Dana will be cut then to the needed width .
I really like the American Racing Torq Thrust 15 x 10 rims , or the Billet Specialties Street Lite
What is the largest tire that will fit up in the wheel well , I'm open to moving the Dana back some if it doesn't hit the fuel tank .
Any pictures and suggestions from you guys ?
