These tires are absolutely pathetic.
BMW fitted them when I bought my pre-owned 2012 320d coupe in January 2016. I tried to specify none runflats but they insisted that these are standard fitment, they had to go on or I wouldn't get any new tires.
As many other people have mentioned the ride quality is just woeful. I have the 19" sport plus wheels and cringe whenever I drive over a pothole, grid, manhole cover, broken tarmac etc. It feels like an alloy is going to crack or dent but I have been lucky so far. Parts of the interior trim rattle or creak as there is no forgiveness in the tire whatsoever.
In terms of grip levels and handling, the tires are OK. Wet performance is quite bad, dry is quite good. They do not inspire me with confidence in any condition however. I am a highly trained driver due to my career and feel the Hyundai's, Peugeot's, Focus's and even vans on mid-range tires have much better feel and predictability.
After around 12000 miles the rears are nearing the wear indicators. I intend to replace all 4 this week and have been researching Goodyear Eagle F1 assymetric 3 and Michelin Pilot Sport 4S. As for the Bridgestones they have about 6mm of tread on the front and 2.5mm on the rear. If this review hasn't put you off enough then they'll be on EBay very soon.
