bias ply tire memories.

I remember around 1968 my folks had a Plymouth Fury II wagon to haul all eight of us kids around on vacation or off to the Grandparents house's. At the time there weren't many cars in our neighborhood that had radials with my folks car being one of them. Invariably when we would stop anywhere someone would come up to my dad and say the wagons tires where low or flat. My dad would patiently explain to them the difference between the radial and bias ply construction and that they were properly inflated.
