Living in Maine with a long commute and the potential for heavy snow, I replaced the stock tires with Bridgestone Blizzak WS70 snow tires. I drive from Portland to Augusta, Maine most days. This is a 90% freeway drive. The Blizzaks are awesome in all snow and ice conditions, and don't add a lot of road noise on the highway when it's dry. The only time that I ever had a snow challenge was after a blowing snowstorm added a 20" drift in the front of my car. After brushing off 8" of snow off the top of car, I decided to see if I could push my way over the drift without shoveling. I rocked back and forth a three or four times and pushed through the drift to the plowed section and off I went. The Maine highway folks do a good job of keeping the freeways plowed, so mostly I end up driving in slush or snow pack. While I don't drive much over 45 mph in these conditions, I have complete confidence in my Fusion / Blizzak combination. At 45 mph, my Fusion switched between gas and electric as I mushed along the freeway. I ended up around 38 mpg for that trip. There has been a big dropoff in mileage since the warm months when I was averaging about 38 mpg. Now, it's down to about 32. My last refuel was 30.8, but the temperatures have been really cold, between -5F and 10F. I haven't noticed a significant drop in gas mileage with the snow tires. If you want to see the graph, look here... Fuelly All in all, I have no reservations about buying a Fusion and adding snow tires if you are in snowy climates. Myron
