Goodyear Eagle F1 Asymmetric 5 vs Kumho Ecsta PS91 — Compared

“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.”

“You will get smoked if you go with the PS91. They also do not hold well under abuse. I feel that the RE-71RS would be a better value for you simply because they'll hold and remain consistent even as they wear very far down. I've used the RE-71RS at a track day before and even as the tires were chunking and melting, they still maintained their grip, as if they were just BEGGING to be abused, to see how far they could be pushed.”

“New meaty tires set up installed, now I can order spacers Went up tire sizes and they definitely fill the gap a bit. First time running sticky kumhos on anytime so excited to see how they turn out.Specs are Kumho Ecsta Ps91 235/40/18 up front and 265/40/18 in the rear. Read more”

“my turbo came with a set of Kumho Ecsta PS91 in the OEM widebody sizes that were around a year old and had maybe lost 15% wear. coming from someone who loves PS4S, i hated them. grip was subpar. it felt wasteful to toss them though since they were relatively new and had decent tread left so i toughed them out. i got maybe 2k miles out of the rears before they needed replacement just from normal street / occasional spirited driving. they are not a great handling tire and they are quite bad from a wear perspective as well. just buy michelin or even continental and don't look back.”
