I don't mind them on the BMW 135i, but the lack of grip compared to normal summer tires kind of sucks. They're also heavier, which we all know and hate. I just purchased a BMW M235i with regular summer tires and apparently they include a repair kit. I also may get run-flats as my winter tire set, just because I wouldn't want to be dicking around with a repair kit in sub-zero temperatures.

For people that don't pay attention to ride quality or handling they are great. Very convenient. For everyone else they aren't great, but they are livable.

 

I have them, two words: "THEY SUCK!"

Now S Class comes with RFT, you should go see the new owners complainting. Just like BMW owners been
doing for years.
