Being in college I have a budget. Winter tires and steelies are going to run me like 450 dollars. For that price, I could get some pirelli pzero all season tires, but would have to run them on my stock wheels. I have 15k miles on my potenza's and I have no clue how much longer they will last, so I do not want to have to spend money this coming summer on new summer tires also. I have not really ever driven that much in snow, however, I do visit west virginia frequently and during the winter I did have to drive on snow packed roads there, last winter I would say i drove in snow like 5-6 times but not in my msp. Would snow tires be a wise investment, or should i go with all seasons?
