After a sidewall issue with the OEM Goodyear Eagle LS2's, decided to give the Bridgestones a try after reading the reviews. Wanted to stay with a run flat for piece of mind for my wife and young daughter. I was pleasantly surprised with the upgraded ride quality and noise reduction over the Eagles. The car feels like the luxury car it was meant to be now. Not sure why BMW refuses to offer the next gen run flats on their vehicles, but these are certainly a welcomed upgrade to ours. Highly recommend these tires if you are looking for run flats.
