They are high performance tires - really good ones at that. If you don't want them, I'm sure people will be glad to take them off your hands as long as you don't ask for arms and legs in return.
The other option you have, is buy yourself a set of good snow tires and cheap alloys for the winter months, and keep the PS3s for the summer (I'd go this route).
All seasons are a band-aid in snow. They usually work alright, but they never work extremely well in extreme weather.
