I too am looking for snow
I too am looking for snow tires. I have had my Prius for a little over a year and last winter my original tires did not do well. Acceleration was ok, but stopping was not good. Even in the rain I find that at times when I am trying to stop and hit a small bump the brakes seem to feel like they lock (the car feels like it slips for a moment).
As for gas milage in the winter, there are MANY reasons for lower gas milage including:
1. Yes, the combustion engine runs more to heat the block - usually to run the heater so the cooler you keep the interior the less it will run. This is the same for the air conditioner in the summer.
2. There is additional resistance on the road surface due to wet and snowy conditions. Especially with water, the surface tension and added resistance takes more energy to turn the wheels.
3. The gas is formulated different in the winter. There are more volatiles added (mostly butanes) that vaporize allowing the engine to start. Without this, there would not be enough vapors to cause the gas to ingite. This formulation reduces the amount of energy (Btu) per gallon of gas, thus causing a reduction in mpg.
If you have a Prius and have tried a certain brand of winter tires, please post what brand you had used and how well they work.
For whatever it's worth, I
For whatever it's worth, I bought a set of Cooper snowtires a couple years ago for my '08 Prius. The first summer, I took the snow tires off, and went back to summer tires. But last spring I got lazy/busy
and never took the snows off.
My Prius got just as good mileage running all summer on Cooper all-season tires as it did on the factory original "summer" tires.

Hi Elliot in BC.
I purchased a 2009 Prius in August after reading from Car an Driver that the 2010 Prius Tracking Control is more agressive than in the previous version so I opted for the 2009.
I bought 4 15in steel wheels with hubcaps and toyota regular TPMS valves.
I purchased also 4 15 in Winter tires Blizzack WS 60 and got the whole thing mounted on the car.
We had our first major snowfall this week and I was pleased with the results. Good traction in the snow and icy roads.
In 2008 after driving a brand new 2008 Prius I got stucked on a hill going home and I traded the car for a 2009 AWD Matrix which was using 10l /100km compared to the 4,3l/100KM I was getting with Pirius in summer. I had 16in Wheels on the 2008 and Winter Yamaha G20 tires.
The Blizzak WS60 is a lot better and the 15 in wheel is also better than the 16in.
