My Bimmer was a pitiful car when the OEM runflats hit 15 K, The fun had gone ,replaced by the need to pay close attention to lane grooves and transitions on the road, the car had begun to shake as if one or more of the tires were out of round or balance.. the fronts had begun to cup,and when I took it in to check the balance, the rears had begun to separate the inside tread,,,hard riding nasty groove action made me think about a new car. As I had tried Michelins on my Vette to cure the same issues.. I chose the Super Sport for the BMW..What a pleasant and fantastic change in the character of the car. It turns in predictably, rides quiet and smooth, stays on a line well and the worn grooves dont effect the direction of the wheels as the RF did. I am a happy man and regret not the major money I laid out for the Bimmer and it's convertable top.. It rains a bunch here and I had some concerns about choosing HP Summer tires but as yet have had no problems with puddles and standing water at speed but I marked them down to 9 as they can't shed water like an All Season. Only about 900 miles on this set so can't say about how they will wear but they are very hard so hope they will outlast the crappy run flats...based on my experience I will definately be staying with this tire...did I say love em..I was so taken with them after the install, I put on 250 miles taking the long way home..thanks Michelin for giving back the fun car.. FOLLOWUP.. 6500 miles and still loving these tires..Had a chance to run The Ridge on a track day with the Super Sports ran three to five pounds up on the tires and had a great day..little sign of wear 70 degree day, not much sign of heat or roll off the tires stuck well and predictable and forgiving at limit. Love them would recommend them, will buy again..
