I've had winter tires slide on icy roads the same way as a all season or summer tire. If the road is covered with black ice nothing works. Having x drive is better than just rear wheel drive because if you do slide of the road your chances of recovering your car and getting back on the road heading the way you want to go are better.
(I'll take a BMW with RWD and Snow tires over one with X-Drive and All seasons any day of the week.) RIGHT! Rich@GTB .That really makes sense. But, it depends on the person and what he really believes until he finds out different. Move to Fairbanks Alaska and say that.
