From Reddit, forums and review threads. Not part of our score

Tire A

Bridgestone Potenza RE050A Run Flat

We haven't collected enough community discussion about this tire yet.

Tire B

Michelin Pilot Sport 5

Positive

Community opinion on the Michelin Pilot Sport 5 is overwhelmingly positive for daily street driving, praising its exceptional wet grip, tread longevity, and quiet comfort compared to run-flats and older performance tires. However, several enthusiasts note downsides for aggressive or track use, specifically citing softer sidewalls, muted steering feedback, and poor heat resistance leading to delamination under track conditions. Most drivers consider it an outstanding premium all-rounder for sporty street cars rather than a dedicated track or extreme-performance tire.

“Had both on my ST. The 4S is more performance oriented but it wore out much quicker in approximately 35k kms. PS5 is more comfortable and the wear is slower however it does get noisy towards its end of life. After the 2 sets of Michelins, I tried the Falken FK520 for half the cost of the Michelins but found it to more comfortable for daily driving as it is comparatively softer.”

“I’ve done 20k on a set of fronts that still have ~2-2.5mm left. They’re wearing very well IMO.”

“I've used the PS4S, potenza s001's & sports contact 7. Currently on Pilot Sport 5's and I think they're the best all road "do it all"road tyre I've had on my RWD . The asymmetric 6 is also supposed to be great but I havent tried that.”

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.
