After doing some pretty in-depth research...205/55/16's should do just fine for what you want. This fall I will be purchasing snow tires in that size with steel rims. They should work better in the snow than the OEM 215/45/17's if that's what you have now.I am actually looking for wheel/tires in the other direction. I would like 16" that should give a better ride (I believe). I am an old guy and don't need the new look, I would like a smoother ride. I see that TireRack.com suggests 16" for snows for the Ct200h, but they don't show 16" for summer tires. Has anyone out there used 16s?
