Looking for Reviews of Michelin Slicks SM9+ specifically

[Duane Black]

I may have a chance to get some 27/65R18 Michelin SM9+ tires. That narrow, it would seem that its likely a TCR car. Does anyone have info like....

What "publically available" tire does it drive like?
How do they wear? (sessions/days I can expect)
Do they heat cycle or wear out first?

I really should know this info out of hand, but I don't remember our tire size, I'll check for you, give me a bit.
The S9s are the harder of the compounds we use. The longevity is good, you can run them down to the cords, which we sometimes do. They only come with like 3mm of tread when measured from the depth hole when new, so you can use that as a barometer. If they've been on a race car they have likely had a 40 to 50 minute heat cycle on them.
They are 30 68x18
