An update from my earlier review. My 335d xdrive bought in (Jan 2017) with 225/40-R19 front and 255/35-R19 rear run-flats has now done 20,000 miles on these original tires. They are down to about 5mm tread depth, so just over half-worn, and would therefore expect 30 - 35,000 miles, which is good. Grip is as good as ever. Yes, car is 4WD, but always gripped in swift get-aways on love in wet or dry. It was necessary to make an emergency stop, such that brake lights flashed and hazards came on - it was very undramatic and the car stopped quickly with no noise or drama. The comfort is good, although we do have good roads around here in North Wales. I shall probably buy the same again.
