That's interesting, but I read it differently. The bias ply tires did two things, gave a softer ride and at speed caused the tire to squeez so that less tire tread was meeting the pavement. So the tire at 50 mph was really taller than the radial which flatens out more keeping more tire on the road, better handling. I have some NanKing tires from China that are bias nylon tires, they will try and run the grooves CALTRANS put in the freeways to keep the cars from hydroplaning when it rains. Just the worst tires I have ever put on a car. But I still have them with a set of "Port-a-wall's" installed, nice touch at shows.
