I've run Blizzak DM-V1 for two winters now and have never been disappointed. Don't think I ever spun a wheel and dry road traction is adequate. They do get a little noisy on the highway and wear pretty quick if run much above 50 degrees. Several folks here run them in the winter.
For more all season with decent winter capability, I use Hankook DynaPro ATM RF10 on the liberty and Firestone Winterforce UVs on the WJ. Both excellent tires, dunno if they come in a size you like.
