I have a 2002 Acura RSX with 210kmi and I plan on giving it up next spring for the new Mazda3. The tires are old Michelin Primacy MXV4 that are fine on dry roads but no good at all on ice. If I were wintering in Tucson, I would keep the tires but I've decided to stay in Idaho this winter and that means getting new tires. Should I get winter tires or all-season tires? I have never had dedicated winter tires before. How do they do in the summer? I'm keeping an eye to resale value and I'd like to get something that will maximize resale value but I also want something that performs really well on ice because that will be the environment I'm driving in till I trade the car. What would you do and why?
