So why didn't they give all terrain tires when I got the X-Fire? Should I go to the dealer, order $200? worth of tires, and get them switched, and put the regular ones on storage till spring? Is it the consensus that the problem lies with the tires, and not my car, which during the first snow of the year, almost hit another car going 10 MPH?

BTW, I'm not sure if I did or did not apply the breaks, when I was sliding into the other car. The breaks seem to have a 'grinding' sound, which I thought was just the snow being caught up in the wheels. After the breaks clearly were not working, I might have released the breaks to then swerve into the embankment to avoid hitting the other car. Or I might have done both, I'm not sure.
