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.”

Higher is better. The Relative Score follows your weights below; category scores do not change.
Weight the categories that matter to you
Wet grip starts at “Important”. Treadwear starts at “Neutral” here: road tests measured it for at most one of the two tires, so it rests on owner reviews. Move the sliders and the scores update instantly.
Only one of the two tires has a score here, so this weight changes nothing in the head-to-head.

Michelin Pilot Sport 4
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.
“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”
“Wow! You burn rubber. I totally appreciate what you’ve said and on my old e60 I ran both contis D06 and Michelins ps4 for 3 sets each. Both different feel and wear. Contis lasted longer but didn’t feel as nice as PS4. Now I’m in another BMW and cannot rotate the same way with a staggered wheel size. I’m in NC, when I drove PS4, in cold weather, they wore out quickly. They are a summer tire for sure, but I will use a slightly higher pressure to lengthen service life. That camber is rough on the inner tire shoulder / tread and the all season contains held up better there.”
“CC2s fitted yesterday. Initial subjective reaction are they deffinately seem both quieter and more comfortable than the stock PS4. I did a non scientific noise test using a app on my phone. On my way to have the tyres changed I drove a section of the A460 toward & from Cannock, approx half a mile in each direction. I did exactly the same run at the same speed with the CC2s a couple of hours later. This is a fairly rough surface well worn tarmac but I avoided all ruts & holes. PS4: 41psi 50mph, average noise level 67.4db. The average being registered by the app, not my calculation. CC2: 40 psi 50mph, average noise level 64.6db. In both cases the phone lay on the central console forward of the tray & armrest. The comfort feeling is the CC2s are softer, damping ridges & ruts better than the PS4, while driving a route of 14 miles each way I drive every Tuesday & Thursday & consists of a wide range of different surfaces including the newer super smooth quiete tarmac.”

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.
