My daughter has a 2013 Ford Fusion. It's front wheel drive and every time we get any amount of snow she gets stuck, whether it's just icy roads or snow accumulation. And of course her problem then becomes my problem. The car has 24,000 miles with the original tires. My question is this...How much of a difference will it make if we put really good snow tires on it? And would the front be good enough or would you do all four tires?? She wants to buy an SUV with 4WD but I don't think it's financially feasible right now for her. Also, suggestions on the best snow/ice tires would be great. TIA
