275/40 - 20 inch fronts and 315/35 20 inch rears. They are They are Bridgestone Duel-Er H/P with about 8,000 very easy miles on them. I took them off to put all season ones on since they aren't great in the snow... The Discount Tire guy said he thought they were worth $900-$800 on Craigslist but I listed @ $600 and will consider lower offers. I really just don't want them taking up space in the garage. They came off a 2013 X5 with the M package if that helps.
