What real owners are saying
From Reddit, forums and review threads. Not part of our score
Tire A
Bridgestone Adrenalin RE002
We haven't collected enough community discussion about this tire yet.
Tire B
Positive
Kumho Ecsta PS71
Community members generally view the Kumho Ecsta PS71 as a capable and reliable mid-range ultra-high performance tire offering solid grip and value for money compared to premium alternatives. While perceived as good once warmed up, some drivers note that it does not quite reach the ultimate grip level of top-tier brands and question its tread wear longevity.

“Not exactly helpful but I've got Hankook winter tyres on my 330i and they're really good. mr wilks on here recommend Kumho Ecstas a couple of times so I got a set for my MC and I've been very pleased with them. And I got a set for £400 from Black Circles! ETA My Kumho Ecstas are also PS71.”

“Kumho PS71 Question Replaced an older (2021 or 2022 production) set of ps71 with a new set (production 39-42 week of 2024) and noticed something on the new sidewalls I hadn't seen on the old ones. The new ones have ps71 with either a 1 or a 2 under it right above the bead in very small text. I'm curious what they mean if anything at all.”

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.
