I checked Coker's site and saw that they offer that 775 tire in a 3/8 redline (see picture). Redlines might be better on a pre-69 car since white letters were replacing redlines as the performance-look tire. (Blackwalls are always 'correct' in this case.) Hmmm, 15x4 Cragars with 775 redlines up front and 15x7 Cragars with a G70 redline in back. Might look good on, say, a '67 RS/SS 396...?
