Driving on the snow with RWD Toyota is great fun but that fun ends normaly after new year or something. Till about new year normaly roads are covered with snow, that snow is evenly slippery and smooth but now roads are more like offroad track. There are huge ice blocks every where and normaly there where you least expect them . Roads are extremely rough. We have saying: Like driving on a potato field. I may say that hits the nail on the head this time of year.
BTW. I have super sexy Michelin ms200 165/70r14 now rolling under my car but those work just fine right now.
