The 245/70 R17 is 775 OA diameter.
The 265/70 R17 is 803 OA diameter.
The 245's won't rub, the 265's will rub.
All D3 / D4's have the seam at the front of the rear wheel arch.
It can be either folded over or trimmed.
Folding over is easy if you don't have rear AC as the coolant lines run next to the seam.
If you have rear AC then it is better to trim the drivers side seam and relocate the coolant lines, the passenger side one can be folded over.
