I'm not as old as some of you guys as I grew up in So Cal the 60's and 70's. The only white walls I ever remember seeing with mags (mostly supremes) were on low riders. I think I remember a thread by C9 (member emeritus) where he went into historical detail about what he remembered about blackwalls, whitewalls, wheelcovers, hubcaps and mags, etc. He grew up in So Cal and I regard him as an authority on regional hot rod trends during the 50s and 60s. He was there and in the thick of it.
