Tom, are you sure that's the size? I would have assumed that your wife's Camaro has 14x7 SS wheels and a corresponding 225/70/14. 225/70/15's have looked huge on all of the Camaros I've seen, and would look even more so on a 6" rim, IMO.
I agree that the BFG Silvertown redlines are the best looking/running radials redlines out there. In this case, I would go with the time-proven Z/28 size of 215/65/15.
