I just went from a radial front to a bias rear tire mounted up front, there is a radial GYTT CT on the back. I found my Dunlop D404 to be just as stable as my Avon was. The ride actually seems softer, perhaps due to 11/32 of tread vs the 6 or so the Avon had on it at the same tire pressure. Thats my 2c.
