I have 2011 X5 35d. Need new tires--I bought spare in case I'd like to get away from run flats--ride is quite harsh. Origninal Michelins were poor in snow. Any recommendations, considering Non run-flat tires such as Pirelli Scorpion Verde A/S as well as Bridgestone Dueler HL422 Ecopia, Dunlop Signature CS, Bridgestone Dueler HL Alenzas based on checking in at Tire Rack--Their first recommendation was the Pirelli Scorpion Verdes. By the way the size is 255/55R/18. Are those that replaced their Run flats with non run flats happy?
