I'm using them on my BMW 520d G31 M Sport, quite happy with those tires and maybe because I drive a lot on the motorway (normal driving) lasted over 50k miles on the front (245/45/18) and over 30k on the rear (275/40/18). Pretty noisy on the road (run flat...) and not very good on wet, but I'm definitely going to use them again.

Rubbish tire ever! don't understand why BMW F20 118i chose this tire. Even on dry rode, the grip is terrobile, causing two accidents to my 118i. Under wet condition, the grip is nearly zero under noramal draiving style, with ESP flashing from time to time.

OEM fitted wheels and just need replacing due to wear - lasted 36,000 miles and still 2.5 mm left, but thinking of replacing them for the winter. Good comfort for RFT's, dry grip is decent, wet grip is average - zero grip in any sight of snow but that's with all rear wheel drive BMW's.

When I bought my car these tires were fitted. Only afterwards I learned that BMW delivers some of their cars with runflats as standard. While I was excited in the beginning to learn and feel the runflats, I was dissapointed overall.
While dry grip is average compared to non-RFTs there is no wet grip. One of the worst summer tires in wet/muddy conditions I ever drove. All the rest seemed very average and definately lower performance than all the Pirellis, Contis, and Michelins that I drove (although non-RFTs). They are noisy and very hard. Wear is rather OK.
Compared to their RFT successors (Bridgesote Driveguard) you can really forget about this tire. The RFT technology has improved. This tire I would not recommend due to its wet grip weakness.

Not happy with levels of grip especially in the wet also they give a harsh ride. Tires need replacement after only! 12,000 miles of average driving on mixed roads.
Currently looking for replacement but as the car requires run flat tires the choice is limited and EU labelling indicates theses Bridgestones are the best. whoever invented run flat tires should be ashamed of themselves, wish I could use standard tires but can't as car is designed for run flat tires and also insurance would not provide cover with a change to standard tires.

I bought the tires when I bought the car 2nd hand. I had come down to the 120d from a 523i where I had 235/45/17s but a much larger/heavier car, no runflats and my own choice of unidirectionals. Grip is lower on the 120d, as well as less progressive and decidedly impossible in snow (as the Potenza review), and after just 13000 miles my rears are almost down to the wear markers. The car has caught me out twice recently, but luckily I wasn't driving fast and the ASC kicked in. I am looking for replacements but there's not really much choice in RFTs is there?!
