Tire A

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.

“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.”

“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.
