Kurt, the reason is the orientation of the bands in the tires. On a bias ply the threads are arranged in an x pattern which distributes the load over a larger section of the rim. On a radial tire the bands are in + pattern with the sidewall bands at a 90 degree angle to the rim. This places load from say hitting a pothole directly to the rim over a small area. I wondered it myself and got that info from one of the tire manufacturers website.
