I took my car to Tahoe a couple weeks ago when they got ~6 feet of snow in 3 days. My car has the stock all seasons (Yokohama Avid S34D). Going up the 395, the road was completely iced over for a mile or two at a time in some places. I'd say I averaged 40-50mph on those stretches and to be honest the car felt perfectly fine. While I was in the city, the neighborhood streets were covered in snow and the tires still handled fine, no loss of traction. I honestly think the biggest factor in driving on snow/ice is the way you drive. That's not to say I don't think tires make a difference.
