So they are winter tires, only spiked tires works (really) well on ice, unfortunately you can't use them on most country without majority of the roads iced for long periods... Personally living, and have lived, in snowy area while I prize winter tire on snow I also prize 4WD/AWD, without them in many cases I'll have had to beg for a tow, no matter how good winter tire I can ever mount. In some condition, like little snow, you only have slippery roads due to the moisture of salt/snow/dirt on the road and 4wheel help reaming on trajectory but you may still drive on 2WD at least if you are a good enough driver, on heavier snow 4wheels means have enough traction to advance and enough grip to still have traction when some wheel slip.
