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.

Community members generally view the Goodyear Eagle F1 Asymmetric 5 very positively, frequently praising its wet grip, cold weather performance, and steering feel when compared to rivals like Michelin Pilot Sport 4 and Pirelli P Zero. While some users find them exceptionally quiet, others note moderate road noise or low-speed scrubbing on full lock.
“2024 J1.1 GTS Sport Turismo on 21" Spyder RS wheels here. Went from Pirelli PZero's to NF1 Goodyear Eagle F1 Asymmetric 5's recently. They don't seem any louder than the PZero's, dry grip seems about the same, as does comfort. Wet grip and performance in cold conditions (I'm in Scotland, UK) over the PZero's is noticeably better. Very little in the way of the Ackerman effect in cold temperatures, compared to the PZero's which made an awful noise and skipped badly when turning at slow speeds, pulling out of junctions. Will see how they do wear rate wise, PZero's had about 2.5 to 3mm left at 16k miles. Anything approaching that on the ASY5's would be good. Unfortunately on the J1.1 on 21"'s the choice is essentially PZero's or ASY5's. Which is disappointing as I had PS4S's and CSC7's on my previous cars (G81 M3 and M340i Touring) and they were fantastic.”
“I have them fitted in both my cars (Audi A6 and CLK350). Neither had the performance of your AMG but I can confirm they are the best tyres I’ve ever had in terms of grip and feel.”

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.
