The Genuine BMW X5 E70 20" Inch Style 333M Single Front Alloy Wheel is a high-quality wheel made of aluminium with a stylish Twin 7 Spoke design. It features a grey colour with a diamond cut finish, adding a sleek and sophisticated look to your vehicle. With an offset of 40 and a stud diameter of 120, this one-piece wheel has a width of 10 inches and a diameter of 20 inches. I bought this from bmw to use as a spare but went a different route so I had the tyre removed. it is as new with no marks on it.
