[ACHiPo]

I will be running 255/60s (Cooper Cobra, not Avon) all around on my new 427. This is the same tire size that a friend is running on his 427. Both are later models, however, so Bob may need to weigh in on whether earlier models had tighter vertical clearance. I know Peter was a little concerned with front clearance, but they are fine at least on the newer models.
