Default Kumho Ecsta XS and track heat?

Does anyone have any info on how the new Kumho Ecsta XS stands up to track temperatures compared to the MX? I like the non-directional tread pattern, and I've liked the MX for a street/track tire. But the new lower treadwear rating makes me think they might get overly greasy on the track.

I've been thinking about trying them too. I don't think the treadwear means greasy though. Azenis get greasy and they're a treadwear 200 tire but, RE01-R's don't and they're a treadwear 140.

I found the MX to be a tough but, not particularly grippy tire. I run Azenis at the moment simply because they're cheap. I just slide more toward the end of the session. They really have their best grip on the first or second lap and then it's downhill.

The MX have generally seems more consistent than the RE070s, but being 245/40/18 as opposed to 225/45/17 might have something to do with that.

Thing i dont like about mx's are the side walls.

I hear the xs is great but still has side wall flex, but the tire being designed for the amount of sidewall flex the xs produce.

I'm more interested in trying out the nitto nt-05's then the xs's right now.

NT05s are interesting, but I'm kind of partial to something I can swap side-to-side during a track day.

I run my tires in any direction. As long as it's not raining, it doesn't really matter.

My findings too. They lasted almost a full 20 err 28.x minute session for me. After a few back to back sessions though, they started getting a little greasy towards the end of the session. Best street tire I have been on IMO. I'm gonna try a shaved set for time attack.

For time attack, you're probably better off with something softer.

Tires have to be UTCC 140 or higher for the street class

You know that the tire companies play games with the UTCC number to make the tires more desirable? Take the RE01-R's, they started life treadware 140 and then later versions with the same compound were 180. I was talking to a Bridgestone tech at a track event he claims it was purely a marketing thing. Track people like lower numbers whereas normal people want higher.

Yeah I believe it. I think the Kumho will be hard to beat when you have to run over 140 tw, especially if you through price in as a factor

Ran them at NJMP Thunderbolt in my 951. They did very well for a street tire, lasted the full 20 minutes for me. Very impressive levels of grip. My first time out on the track with the tires so i was being pretty conservative with them, but was truly amazed at how well they stuck through the Octopus.

As mentioned, they are not good at all in the rain. I daily drive the car and driving in the rain always has me 100% focused with the tires. They do not inspire much confidence .

I found a ridiculous deal on some BFG R1 take-offs, so I'm getting those, and I'm gonna get some Kumho Ecsta ASX for my extra set of stock rims for street use.
