I have a 2009 with SP. I live in Northern Delaware. I need tires badly and saved up enough that I could get the Michelin PSS's. which I have wanted for a long time. The problem is the Z is my DD so there is a chance that I may have to deal with some driving in the snow, not alot , just enough to get me home from work etc. I have enough vacation time that I would not have to drive it in a large amount of snowfall. I know the PSS is strictly a summer tire. I am considering buying a set of all season tires to get through about March but I don't want to sacrafice performance. Would an all season tire be really that much better or should I just go ahead and go for the PSS's. We could have a cold , snowy winter or a mild winter ( like last year ) around here so I just don't know what to do. A tire guy suggested trying the General G-max all season tires which are way cheaper and still have a reasonable amount of performance. I am just stuck on what to do.
