I purchased Goodyear Eagle F1 all season tires. They can be expensive but I shopped around and found them for $145.00 a tire. They are wider than the stock tire (from the rim protector feature, which my wife has used!) and give outstanding performance is all seasons. (I live in Wisconsin.) Had the stock tires for the first year and they sucked in snow. Put the Goodyears on before winter this last year and could tell the difference the first snow. They ride a little rough but I figure the handling and traction you get from these tires is worth the ride. (This is from the carbon fiber reinforced side walls.) So give them a try....
