My mom first insisted on AWD. Ok. Now she insists on having dedicated snow tires. OK. She also has said that she doesn't want to have to be bothered getting the tires mounted onto the stock wheels every year and wants seperate wheels. what would cost more? And what combo is the best bang for the buck snow tire and wheel size wise. This is NJ and we don't get near as much snow as the Great Lakes region. In fact last year we had a very high amount at 40 something inches i think. What should we do? We are willing to spend a little extra for better performance, but it better not suck in regular conditions.
