Reducing unsprung weight and improving your BMW's grip on the road is what the Lightweight Performance Wheel Set is all about. These wheels are built to Dinan offsets and sizes to accommodate substantially larger tires without any rubbing or modification of the wheel well. Each wheel is cut from a single solid block of aluminum creating a very strong wheel that is also light in weight. Throw on top of that great looks from a popular design and it is a winner all the way around. Front recommended tire: Michelin Pilot Sport II - 275/30-19 (M5), 275/35-19 (M6). Rear recommended tire: Michelin Pilot Sport II - 295/30-19.
