Higher is better. The Relative Score follows your weights below; category scores do not change.
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.

From Reddit, forums and review threads. Not part of our score
The Kumho Ecsta PS91 is widely praised as an affordable, budget-friendly summer tire with attractive styling and respectable wet or daily street performance compared to pricier rivals like Michelin. However, several users express frustration with poor tread life, rapid wear, and insufficient grip or heat endurance under hard driving and track conditions. Others also note issues with sketchy handling, flat-spotting, or vibration when cold.
“They were good enough for 1:46.708 at Mazda Laguna Seca 285/35ZR-19 Actually, thats better than I thought”
“no more Kumho Ecsta PS91 for me I have 2015 Mustang GT Premium with 20" wheels. I bought the car new, and it has just over 155k, and the only thing I have replaced is the water pump. However, tire wear is a problem. The alignment is good, and I had the camber adjusted (front and rear) so that the tire has less negative camber than it had when it left the factory. Despite that, I'm only getting about 15k miles out of a set, and I drive it very gently. I've been buying Kumho Ecsta PS91, but I'd like to try something different. What do you recommend?”
“I have the XTS variant of this tyre on my Ram srt10 and the drive nicely and don’t tramline.”
Based on 45 community posts
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.
“Those are Kumho Ecsta PS71s, thread width is supposed to be 245mm, the actual one is hardly 235. How so?”
“go with Kumho Ecsta PS71 EV around £140 – £165. Good value for money”
“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.”

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.
