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.

Kumho Ecsta PS31
We haven't collected enough community discussion about this tire yet.
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.
“Quote: Originally Posted by weston.__ I will be going down the non-rft route, Pilot Sport 4.

I went from Bridgestone S001 RFT to 'go-flats' and have found the suppleness an obvious difference. Since I put the pressure to the mid point between the low and high load plated pressures I have yet to have any of the heartstopping thumps come through the suspension that the Bridgestone seemed prone to.”
“Reminder: Tires are the key to this car Just replaced my Michelin Pilot Sport 4 AS tires with a new set ahead of the rainy season. Lasted 36K miles. It was the best mod to the car and a fresh set reminded just how good a brand new set is. The car is glued to the road, riding wonderfully smooth and quiet. Spend the money, get the best tires for you. The tune can wait. And it will need it.”
“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.
