Today I finally got a chance to take it for a spin on the snow on my all-season Yokohama W4S tyres. Overall, my confidence level has definitely dropped after driving on these (compared to driving on snow-rated tyres). The car slides easily on the turns and locks tyres on breaking. I forced it few times in into the drift, just to feel the control. Luckily they are sort of predictible for now, perhaps because they're almost brand new. We'll see how they behave in a heavier snow storm.
