Well, here we don't often get snow, but we do get sleet and freezing rain occasionally. Plus I travel to points north (not too far). I would hate to be caught out in bad weather like that with tires that can't handle it. I would like a performance tire that will support the MINIs capabilities, last significantly longer than 30k and won't put me in the ditch if do find myself in poor wintery weather.
Define "All Season".. Do you really need snow capability? If you can look past that there are many tasty possibilities..
Cheers,
