Best test result: #1 of 45 in 2019 Summer 53 Tyre Braking Shootout (dry braking)

“Those are Pilot sport 4 (all season). If it had s after the 4 it would be the summer high performance version. I put the pilot sport 4 on wife's GTI autobahn 2016. Great handling tire, stiff side walls, not the smoothest ride but best overall.”

Tire A

Kumho Solus KH25

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

Tire B

Michelin Pilot Sport 4

Positive

The community widely regards the Michelin Pilot Sport 4 line as a premium upgrade offering exceptional dry and wet grip, precise handling, and superior ride comfort compared to OEM or run-flat tires. While celebrated for performance, users frequently discuss its high price tag, faster treadwear, and noticeable drop in EV efficiency. Some drivers also note increased road noise and reduced traction when temperatures drop near freezing.

“First time post for me on Bitog. I just installed the new Michelin Pilot Sport 4 AS tires on my 2017 Mazda GT. Noise doesn't seem to be an issue I'm experiencing. Prior to the new Pilot Sports 4's all seasons I had the Michelin Pilot Sport AS 3+ and the 4's are much quieter on the Mazda. The 4's feel a tad bit softer in ride, quieter and handle just as nice. However, they are new rubber and the tread pattern is completely different from the Michelin Pilot Sports AS 3+ . I've only put about 500 miles on them, but so far, I really like them for their ride comfort, noise, stability and wet/dry grip levels. They feel like a more mature AS3+ if you have them now”

“Switched from the garbage stock Potenza's to Continental DWS06 a week after grabbing my Z. Absolutely fucking worth it. I got Swift R lowering springs installed and that also made a great improvement. Z feels much more confidant and way more composed on my twisty roads and roundabouts My ND Miata also came with the same Potenza's and I went with the Michelin PS4's. Transformed the handling as well”

“Have you checked to see if your wheels would accommodate a 215 tyre? Might be worth investigating. Other than that, Goodyear Eagle f1 asymmetric I would say have just as good dry performance as a PS4. They're minutely less grippy in the wet, but not noticeably so. They're also a lot quieter and a lot cheaper. I've run both PS4 and the Eagles on track, and now the Eagles are my go-to.”

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.
