'66/'67 GTO's are tricky to fit a rear tire. Those voluptuous quarter panels make you think there's a lot of space, but as was stated earlier, they won't even take what fits on a Chevelle. When we built this '66, we found that the inner fender outers are shaped a lot more conservatively, and come in even a bit more than the fender lip as I recall. Early '66 GTOs were fitted with the '65 width rearend, before changing to the "wide track" one inch wider unit for the rest of '66/'67 production. On this car we used stock wheel wells but had a custom 9" rearend made. With that rearend I was able to use a 255/60/15 on an off-the-shelf 15x8" Specialty Wheel (via Coker) chromed Rally I.
