You talking snow and ice or just rain?? If it's snow and ice, I would consider getting a set of dedicated snow tires and another set of tires for summer. If it's just rain...then a soft compound tire with a directional tread would work well. depends on what you're budget is and where you live.
For me in WI, I have a set of snow tires on my stock 15in that I run in the fall and winter and for the rest of the year, i run a set of High performance summer only tires.
