For getting stuck, get a set of Goodyear Assurance TripleTreads. I got rid of the OEM tires after I destroyed two of them. Yes the Conti's aren't really that great. I managed to get stuck in our work parking lot pretty much every day last year and had to "rock" the vehicle so I could back out of my parking spot. Unfortunately, since I purchased the new tires, I haven't had a chance to try them out on this car, but on my other previous Foci, the TripleTreads worked great. Part of the problem with the Focus that I can see is that it is so low to the ground (so clearance on unplowed roads is an issue).
