Bought 2011 Touareg Sport and it had new Cooper M&S tires on it. It handled great on the snow and ice yesterday on our first trip, but I think I am getting a great deal of tire noise when we drive. This vehicle has it's fourth set of tires on it in 53,000 miles. Would it make sense to buy a set of all-season or highway tires to put on in the spring and run until the late fall when it starts to snow? Or, does this vehicle just eat up tires and I have to live with it?
