Bridgestone Potenza S001 RFT 

Affordable Quality Run Flat tire Made in USA. What else matters? Great traction even in heavy downpours. Good driver feedback,
No surprises. Soft compound so count on short shelf life. Same tires are on my wife's A5 with No complaints. Will definitely buy again.

Only 3200 miles so far on these BMW OE factory issued tires, so I will be updating this review at some point. This tire is surprisingly good in wet conditions. Driving in some not-so-light rain, I felt confident with grip in turns, and cornering. Braking, and acceleration in these wet conditions was also better than I expected from a summer runflat, and I did not experience hydroplaning.
In dry roads, steering response is very good, and predictable. But I didn't rate it higher in 'cornering stability' because I have not had a chance to push them closer to the limit. Very grippy when hot on clean asphalt, but careful of those dusty/sandy/fine loose gravel on edges of hwy on/off ramps, as these tires broke loose easily in those conditions.
It seems they have improved the comfort level of run flat tires. The ride does not seem as harsh as I remember driving other BMWs with runflat tires. However, I could see how some might complain that they are a little noisy. With decent speed on windy roads, I can hear the rubber scrubbing off the tires. Wish I had better roads around here to do more "spirited" driving. But if I did, I would probably wear these tires out faster than they are rated for. But that should be expected from performance summer tires. For now, I am satisfied with the performance of these tires.

Bought these thinking they were the Extreme Summer Performance tires. Found out much later they were not.

I used them primarily for travel to / from autocross events and rare trips outside of that.
Outside of autocross, they are great tires!

It drove them mostly on dry pavement. Traction was great for driving around town with very little road noise.

I can't really comment on wear as I used them for autocross. By the third event, about 300-500 miles, they were showing considerable wear.

Drove in the wet maybe two or three times. Felt great driving around, didn't experience much hydroplaning, but I am in an AWD car, so other platforms may experience it differently. Stability in corners felt great as well!

Overall, great tire if you don't want the Extreme Summer tires. If I had not used them mainly for autocross, I'm sure they would have lasted much longer that I had them for.

Tires are solid for a summer tire, great traction in the curves on the highway and no roll on cornering in the city. They're stiff and a little rough on bumps but that's the trade for the control they exert on the road

These tires are awesome. Excellent traction. I purchased old stock on clearance and I am very pleased with them. They were a little difficult to mount but are otherwise excellent. I put them on my lowered 2000 Chevy S-10 4x4 (with aftermarket rims) and the cornering and braking performance are very impressive.

OEM tires. Very solid performing RFTs which have held up very well over the course of their 6 year life. Swapped with Goodyear F1 A/S non-RFTs for winter seasons since 2016. Driven on three continents; they are very faithful, and exceptionally responsive tires on dry surfaces. Only cause of more than normal wear is FM 2222 in Austin in dry conditions between Mopac and FM 360, twice daily, when they support about .8G in a 'spirited drive'. As they have become more worn, the changes in road surface feel has become more pronounced, but no change in road noise, which is louder than I'd like. I have definitely learned to slow down on damp and wet surfaces on these Bridgestone - you can definitely feel the car float on damp surfaces. These tires actually have been more durable than the original aluminum alloy wheels which have gotten out-of-round thanks to Texas road surfaces which are more suitable for light truck tires.

Excellent performance tire without sacrificing ride comfort.

It’s a great purchase. Tires have been excellent so far. More comfortable than the stock Pirelli all-season run flat tires.

Good buy , smooth quiet ride, feels good on highway and ttaffic.

These are the factory-installed OEM performance tires for my F30 328i M Sport running the 400M style staggered 18" wheels. Running 225/45-18 Front, 255/40-18 Rear. I was apprehensive at first because I was expecting the Pirelli Cinturato RFTs and instead got Bridgestones. My mom's E90 328i had the previous generation Bridgestone RFTs, and they were very poor tires with rock hard side-walls and unimpressive handling. My BMW dealer assured me that the new generation Bridgestones were improved. They were right, because this tire is a far cry from earlier models. Handling and responsiveness is good, and being that these are performance run-flats, the quality is pretty impressive. They are great in the rain at interstate speeds of 70+ mph. I've been in some heavy stuff, and I've been happy with what I've seen. The traction is solid in most conditions, but these tires will break loose at the first hint of sand or dirt on the road. Another issue is something I've seen from Bridgestones- they don't talk to you. Some tires will talk and make noise as you pull near the threshold of grip. These tires make very little noise until right before the tires break loose, which is fortunately higher than expected. I hit a lot of freeway cloverleaf ramps at speed, and these tires will hold pretty high speeds, so all is not lost.
The biggest issue you will always have with RFTs is the ride quality. The ride comfort is significantly better and more compliant than previously, and for a RFT they're very good. Still, you feel all of the bumps and road imperfections with these. It's unavoidable.
Treadwear is marginal. Middle of tires are 9/32 (-10%). Insides and outsides of tires are at 7/32 (-30%). Wear rate is pretty even, and I suspect I'll get about 15,000 miles out of these tires before they need replacing.

These are the tires that the car came with new from factory. At 33,000 miles they are pretty much shot but I was expecting only 20,000 since they are a max perf summer tire so I'm pretty happy with the wear. I drive a 40 mile round trip commute mostly highway which may account for the longer wear life. I take curvy back roads rarely but do drive spiritedly when doing so. I've never had a problem with traction dry or wet but we've been in a drought. My car also has standard suspension and only 18"s so the ride is pretty comfortable for a sport suspension to begin with. Even now, the tires aren't that noisy. Overall pretty happy with this set of tires, I'll have to replace them with the same tires since I'm returning the lease and there aren't many alternatives for OEM BMW tires in this particular size. If I was keeping the car, I'd get a set of non-RFTs.

I like the Potenza S0001 a lot. They are OEM so I bought them again. They look aggressive and really fill the wheel well. It also has great rim protection, with a noticeable lip. The traction is amazing and they are not loud until they get worn down. That said, they don’t last long. Maybe 22,000 miles. Since I switch to winter tires and don’t drive as many miles as I used to, I figure these will last a while. Another con is that they are expensive, but if they are good enough for Alfa Romeo engineers to put on one of their sportiest models, they’re the right tires for me.
