These are runflats fitted to an F30 LCI 330D M-sport. My last car (also an F30) had Continental SportContacts and even in their worn state were quieter running than these. These are lasting 50% better than the Conti’s though. That’s really the headline for the 2 main runflat choices for the current 3 series.

My interpretation is that these must be on a harder compound. The Bridgestone wins significantly for mileage and also steering feel is better. The Conti’s are quieter and better riding, but suffer significantly faster wear. As for grip, the Conti’s hang on longer outright in both wet and dry, but the Bridgestone’s have the edge for breakaway progression in the dry. You pays your money, you makes your choice…

Spec'd these on a brand-new M140i, have done 4k miles and have just had them removed and replaced by some Dunlop Sport Maxx RT2 tires! instantly feel the difference in feedback, comfort and grip. I would totally avoid this tire... really average grip in the dry and appalling, borderline dangerous lack of grip in wet conditions. Also they are a very loud at speed and crash over even small imperfections in the road surface.

10K Miles worn out, hit a cats eye and you dont know where you will end up. It feels as if the sidewall is made out of wood, the worst tires ever.

Excellent tires. Incredible wear, now up to 42,000 miles & plenty of tread left. Will definitely replace with the same again.

These came new with the car and they are quite simply the worst tires ever. why on earth bmw put these on any car is beyond me they are simply dangerous there is zero grip in the wet and in the dry its doesn't get any better. can't wait to get rid.

Came with the car new and having come from Michelin Pilot Super Sports on my previous car these tires are quite simply awful. I dread the trip to/from work if it's ever raining! In all conditions they're very uncomfortable and feel more like a solid rubber tire and tramline on anything less than billiard table smooth roads. Totally agree with a previous review that they make driving in the wet an unpleasant and dangerous experience. Only done 4,000 easy miles on them still look like new but wet grip is like a set of worn out remoulds. Would never buy a car again with them on!

Skittish in damp conditions, noisy on the motorway, expensive, not much to like to be honest.

Simply outrageous on wet roads. It makes the driving experience of a BMW a truly unsafe and unpleasant one. On moderately to highly damp road, especially on white lines, it simply can't keep the car on track, and it is only thanks to the electronics that I could avoid a close encounter with the road kerb on several occasions. On dry conditions, nothing to declare: it works, like any other no-discount tire.

I found these tires gave a soft ride, but wore quickly. The dry grip was not fantastic at the end of their lifespan but wet grip should be the talking point here because these are the only tires where I lost control of my car in the wet. After this I have viewed these tires very poorly - sure the accident could have resulted from other factors but its hard to rule out the tires entirely.

Comfort , noise and road feedback , rolling are ok, dry grip is average. Wet grip is the weak side, I use Bmw and Dsc always on with this tires on wet when accelerate. Otherthan that average tire.

Excellent tire on RFT. Had mixed dimensions 225/40/R19 front and 255/35/R19 rear and running on very hot climate (Dubai). Tire is perfect as factory fitted choice of this car, super dry grips, comfortable and not noisy. Coming for a long experience of RFT tires with BMW cars, I wondered initially if this was an RFT tire, but, big BUT: Make sure you have the exact pressures as recommended. Nothing more, nothing less. Expect to replace the soon though, 25,000KMS is the most you can do with them..

R56 Mini Cooper S - Australian roads. I'm a spirited driver in this go-kart. All tires are different on each and any car - so many variables, country you drive in, weight, size, car set up, country of manufacture etc. That said I had put these run flats on to replace the last two the noisy factory tires (which I happily forget now) after they had worn. I hated run flats - what a scam I use to think. Until now.

I haven't looked back with the Potenza - quieter, nice feedback (no understeer) and they run great in the wet - even the BMW dealer service guy said for the money, these are what you want to run a Mini Cooper S on.

They have also dropped in price in the past 2 years now - 2014 (about 250 AUD), much less expensive from the factory which were about 150 AUD more than the Potenzas.

I love em'.

I won't bother taking the car to the snow - the Mini is too low and has no business in those conditions - so omit that point of view for them. My gut says they would suck anyway. Shop around - some guys will make you think that these are an expensive tire... they're not for what you get.

No silver bullet tire out there - I don't expect long life they grip to good and just broke in at 1500K in winter/spring, it's early days yet. fingers crossed.
