What real owners are saying

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

Tire A

Kumho Ecsta PS71

Positive

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.

“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.”

“On Blackcircles all the 245/40 R19 ditch finders cost around £100 and have a poor wet grip & all the decent mid range cost around £170 and have A rated wet grip. Would you risk it for £240? I know I wouldn't. The cheapest A wet rated is a Kuhmo Ecsta PS71 at £136 if you really want to keep the cost down. If you want a relatively soft comfortable tyre then a Hankook S1 Evo 3 is an excellent choice.”

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.
