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.

Themes extracted from owner reviews found online — not the opinion of TireWheelGuide.
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.
“New wheels and tires for my ZHP My old wheels were super beat up and tires were showing wire so I figured I’d upgrade both. Was able to get these freshly powder coated squared set (18/8.5/et 50). Im excited to feel the Kuhmo Ecsta PS91 as they are a budget friendly performance tire. 255/35/18 tires all around”
“I've only got a couple thousand on them and just spirited driving in the mountains. I think they will easily go over 10k even with a few track events. I am thinking about getting a set for my SVT focus as I autoX with that car, much easier to drive at the limit than a turbocharged S197.”
“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 opinion on the Goodyear EfficientGrip family is mixed, with users frequently praising its high tread life, comfort, and solid wet braking compared to rivals. However, several drivers express concerns regarding soft sidewalls prone to pothole damage, vague handling dynamics during spirited driving, and disappointing cold or wet traction when used out of season. Many discussions also center on comparing it against alternative touring tires like Michelin Primacy and Continental PremiumContact.
“Nov KUMHO ecsta sport ps 72 ili minimalno korišćen GOODYEAR efficientgrip 2? Pozdrav, molim za savet ko je imao iskustva sa ovim modelima guma. Trebaju mi letnje gume za Mazda 3 2.0 benzin 150 KS (na sport oprugama) i imam dve ponude: Nove Kumho ecsta sport ps 72 ili (pouzdano znam) 2000km korišćene Goodyear Efficientgrip performance 2 sa DOT 0726. Cena je bukvalno ista, godišnje prelazim oko 6k, volim da vozim dinamično kada može. Za Kumho sam čitao da je skoro predstavljena i da je solidna dok sam za Goodyear čitao da je za udobnu vožnju bez dinamike. Da li suštinski ta "sport" razlika može da se oseti u povremenoj dinamičnoj vožnji toliko pa da ima smisla odustati od povoljne odlične premium gume? Read more”

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.
