Tire A
Mixed
Bridgestone Potenza S001
Community sentiment regarding the Bridgestone Potenza S001 is predominantly mixed to negative, particularly concerning the run-flat variants. Drivers frequently report stiff sidewalls, harsh ride quality, road noise, premature wear, and tread cracking, leading many to switch to non-run-flat alternatives like Michelin. However, several owners find them adequate for spirited driving, citing satisfactory dry and wet grip as well as acceptable ride comfort on specific vehicle setups.

“Brand New Bridgestone Potenza S001 Tyres worn after 10k mileage? So I got 4 brand new tyres last June from Costco, 255/35 R19. I only drive locally, occasional trips to another city. 10k mileage later, my front two tyres flagged up on my recent MOT as : Nearside Front Tyre worn close to legal limit/worn on edge CHANGE ASAP (5.2.3 (e)) Offside Front Tyre worn close to legal limit/worn on edge EDGED (5.2.3 (e)) Seems surprising to me as I don't drive crazy, occasional spirited driving. 2011 Audi s5. is this normal? Thinking of getting another brand this time for the front two tyres. Car is a quattro but same types on same axis should suffice? Any recommendations on tyres? Read more”

“I run the Bridgestone Potenza S001 Ultra-High Summer Peformance Tire 215/45R/20s on the rear and 195s on the front. They ride softer than stock tires. Not cheap tho.”

“Thanks for the comments. I'm not sure a paltry $3m fine will move BMW to more or quicker recalls. It's just a drop in the bucket for them. In this case too, BMW has yet to accept any responsibility for the tire issues and has put it all on Goodyear for warranty and replacement. This is the sort of BS thing I am expecting to happen, although unlike the LS2's, I have been assured that there are no Excellence tires to be had anywhere. I just hope they do the right thing here. The latest issue of Roundel reviews the new F30 and they claim the new Bridgestone Potenza S001 uses "third generation run-flat technology", whatever that is, and say its a great tire. I called around though, and no tire dealers even have that tire in their system yet.”

How do we compare tires?
Every category score blends two independent signals. 60% comes from professional tire tests (braking distances, lap times, noise measurements), each result compared with every other tire in the same test and newer tests counting more. 40% comes from owner reviews found online, adjusted for how generously each site rates. Both use one scale: the average tested tire gets 70, the best 100. When a tire has only one of the two, the missing half is estimated from the other and the score stays closer to average; with no road test and fewer than five owner reviews it gets no score yet.
Handling is the exception: road tests measure it inside the dry and wet scores, so its own row comes from owner ratings only and starts as less important.
