Dynaflash8, I don't know if it's a generational thing, but you may be right. The 50s is a decade that escapes me. I'm not interested in the cars, culture, or music. I grew up in the 70s and 80s, but my family always had cars of the 20s and 30s.
I think white walls look fine on cars of the 50s and 60s. They are appropriate. In the 20s and 30s white walls were almost never fitted to cars from the factory. If you look at old period photos, maybe one car in 20 had white walls. I think that people started restoring pre-war cars in the 50s and 60s when white walls were all the rage, and so they became normal for pre-war cars. Now, these cars have had white walls on them longer than not, and so we see them as correct. Almost every Model A has white walls today. Whenever I see a Model A with black walls, I smile.
As for my cars, Franklins almost never had white walls, almost as a rule, unless it was a special show car. I think cars of the early 30s look cleaner and prettier with black tires. White walls remind me of a woman with too much makeup, it's there to hide the ugly.
By the way, my two Corvairs, my only post-war cars, both have narrow white walls.
