Stock tires are OK for summer but for rain and winter, don't bother. Buy winter tires on dedicated rims. Once I wear out the stock tires I'm considering Pirelli P7 or Goodyear Eagle F1 or Goodyear Eagle Sport. I'm still undecided. I have 17" steel wheels w/ Goodyear UltraGrip Ice WRT for snow tires. A great winter tire.
