I have the Blizzak LM-60, 225 all around, they're pretty nice. Several friends in my area also run them and have no complaints (they recommended the LM-60s to me). The ride is soft and they are quiet on the highway. You won't get as much road feel with them compared to a summer tire and the traction control nanny comes on easily if you push it (I think it's over reacting esp. with the LSD). I can't complain overall, considering what they are.
