So I swapped my winters for my MPSS last week and what an experience this morning. Woke up to a frozen driveway, and the road had about an inch of frozen slush.
Put the car in reverse gets stuck on the driveway. Turn traction control off and get it off the driveway and got stuck in the middle of the road. Had to shovel all around the car and make a path back to my driveway.
I guess folks weren't lying that the MPSS are totally useless in winter conditions. It was fun to watch other cars struggle up the hill though, I was more worried about them rolling back down into my car that was just sitting there vulnerable.
At least my wife had a great laugh watching me struggle and saying told you not to swap the tires out yet.
