Hankook Ventus V12 evo2 vs Kumho Ecsta PS91 — Compared

“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.”

“Pretty terrible idea, the PS91 will not have the same heat capacity as the V730, so your front/rear grip balance will change wildly during a session. With the non-200s on the front, at least you’ll understeer instead of oversteer/spin, but not ideal. An experienced driver might be able to work around this, if you’re new, this would be a dangerous situation. Similarly, I wouldn’t mix something like a yokohama AO52, which delivers all of its grip from cold and tends to overheat within a couple laps, with something like a hankook RS4, which famously takes some time to warm up and then delivers consistent grip for a long time”

“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.”
