Best test result: #1 of 10 in 2022 AutoBild 19 Inch Summer UHP Tyre Test (curved aquaplaning)
“Much deserved extra care and new PS4 tires today! Switched over to Michelin PS4 High Performance summer tires from Continental run flats on my C43, and it’s a world of difference in terms of ride quality and noise. She also got the much needed love and care with a nice hand car wash! Jealous GL63 peeking from behind, next post will be a side-by-side photo!”

Tire A
Michelin Pilot Sport 4
Positive
Community opinion on the Michelin Pilot Sport 4 (and PS4S) is overwhelmingly positive, with users frequently praising the massive grip, excellent steering feel, and dramatic improvements in ride quality compared to OEM run-flats. While some note that they wear out relatively quickly and can be noisy on highways or sensitive to cold temperatures (below 40°F), they are widely considered a top-tier performance tire for both daily driving and spirited use.
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.
Community buzz from Reddit and forums is shown for context only — it never changes the score.
