Back Spacing ?
I am running 15x8" rims with 4.5" of back spacing on the rear of my 68 Barracuda with 255/60 tires. There is about 1/2" of space to the spring and the widest part of the tire.
If the rim had less back spacing a 275/60 would fit with no concerns.
John, FWIW, I have never heard of a 265/60 tire, I think you will need to work with 255/60, 275/60 or 295/60.
