I just got my tires and rims mounted today and they work great! No rubbing or anything, and I can even rotate them! I have a 1968 Chevelle SS with 4-wheel Drums and no modifications. The combo is...

15x8 w/ (4.5" Backspacing) Centerline Terminator Series "Telstar" (x4) Summit Racing hands down best price
265/50/15 B.F. Goodrich Radial T/A's (x4) Local Tires Plus
7/16" acorn style lug nuts w/ locks (local Checker Auto)

I just wanted to post this here because when I was looking for the info, it was hard to find. I'm Sure this combo would work for any 64-72 Chevelle/El Camino and as long as the B.S. is the same, Diffrent tires/rims would work too. I wanted to get the widest tire crammed into the front and back so I could rotate them when the backs were fried. Good Luck! I will post pictures when I get the chance.

So where are the pictures ?

Come on now, you got to post pictures, when you get new rollers, its tradition.

Sorry for the wait. They are the same all around. There is about 8" of tire on the ground. The only complaint I have is that the car wants to steer itself at higher speeds. Probably because there is more area to grip now... Here it is:
