I currently have 195/65-15 on my car, and use those for the non winter season. I want to buy winter tires to fit the 15" rims that i have now. Can I get 195/50? or how about 205/55? Will wider tire give you more handling in the snow, or less since the tire will be more likely to roll over the snow rather then digging into it (or something like that). Someone please help me on what to do, thanks.
