I have had white walls, Redlines, and RWL tires mounted on steel wheels with poverty caps, steel wheels with the optional "Custom Wheelcovers", Pontiac wire wheels, Rallye 1s and Rallye IIs on various GTOs. I liked them all for various different reasons. Biggest deciding factors I think are the car paint colors. Different tires look better with some colors than others. Personal preference.
Currently have RWL BFGs on my Reef Turquoise 66 Convertible and am happy with the look. I had bias ply 775-14 Redlines when I first changed to the Rallye 1s with this car. Went to RWL radials after a blowout on the freeway with the bias plys. Went with RWL Goodyears at the time as there were no redline radials available back then. Don't have any pictures scanned with the redlines mounted, only with the BFGs.
Have toyed with putting redline radials on now that they are available but really like the look of the BFGs also. Tough decision on any car. Jim
