In 1969 I drove a 1957 oval-window with F-60/15s 'belted bias' tires, which was the best tires available at the time. I had a wheel shop in Portland rivet Buick 8" rims to the wide five centers.
All four corners. On gravel it would turn or brake, but turn and brake and it went in a straight line.
The I found European Klebers. Those were the best (roundest), when they started manufacturing in the USofA they went downhill.
