I recently traded in my 04 Discovery for a 06 RR Sport SC. I live in Buffalo so we get our share of snow. I love the sport but it does not handle the snow like the Discovery did. Also the truck seems to be all over the road. The dealership aligned it for me twice but it still pulls, I really can't take my hands off the wheel at all. The tires are fairly new but I think they are the problem. Anyone with similar circumstances? Any suggestion on a all around tire for the 20" rims?
