The Stovebolt Site Forums The Shop Area General Truck Talk Mixing radial and bias ply tires

My dad mixed them on a car one time. The results were "squirly" as Tiny mentioned. From the early commercials about radial tires I remember them stating that the bias ply tires will bounce vertically (or UP), and the radial will absorb the bounce by flexing horizontally (or OUT) via the sidewalls. It was always considered taboo to mix radials with bias ply tires.
