What real owners are saying

From Reddit, forums and review threads. Not part of our score

Tire A

Bridgestone Potenza RE030

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

Tire B

Kumho Ecsta PS71

Positive

Community sentiment towards the Kumho Ecsta PS71 is generally positive, with drivers viewing it as an affordable, high-value mid-range/UHP tire that performs reliably compared to premium brands. Users praise its wet grip rating, competitive pricing, and overall road manners once warmed up, though some note it provides adequate rather than top-tier grip and raise questions regarding cold performance and tread life.

“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.”

“I've had the PS71 several years ago - it was ok, nothing spectacular. They might have changed the compound now, so it may be better. Its a good tire, I don't remember any real weaknesses, it just never felt like "yeah, this sticks like glue to the road". Edit: I just remembered - it was mediocre in the city - when the tire was not warmed up, but I reckon this is shared between most sport tires with high speed rating. Once warmed up was good.”

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.
