Have the staggered factory set up: 245/45 R 19 Y front and 275/40 R 19 Y rear. These tires are OEM for the 750Li. The Dunlop Sport SP 01 A is basically a solid tire with a good balance of ride and handling. Treadwear is fair for a UHP Summer tire - get 25K out of rears and 18K our of fronts. The fronts start to get noisy around 8K and they wear quickly on the outer shoulder (from BMW forums this is a common complaint of this tire) - a shame to have replace the tire @18K when the middle and inside has 7/32 tread but the outer shoulder is worn down to the belt. My only other critique is that these tires tend to tramline and are hella expensive. This is my 2nd set as I wanted to keep factory ride and handling; however will try another tire next time.
