Plenty of life left, but I guess it depends what you’re looking to get out of them. How long has it taken you to get to that point is probably the more important question.

I only do 4-5 track days per year and they are usually 3 - 25 minute sessions. I purchased them used from a M1 guy who was never going to track and did not want cup 2's. I have approx. 6 track days on them currently after his use of about 2k miles.

You’ve got one maybe two days left in them from my estimation. The outside shoulder looks to be in great shape. Go until you see a healthy amount of cord… stop before you get to carcass

I willfully admit, I took this one a little too far. You can see cords which run around the tire, then metal carcass at a 45 degree angle. These fronts were used about 3 days.

The last ones were from my track mini (also cup 2’s), these were a few from my gt350.

I’d say all in all I’ve corded 16 sets of cup 2’s over the few years I’ve tracked it. My home track is notoriously hard on brakes and tires and I push 10/10’ths

Thank you so much.

Thank you so much.

You’re welcome…. But this is just one degenerate’s opinion

Pilotgore, I have worked with bronze-level pro drivers who couldn't get their take-offs that perfect. You DO know how to set it up and use it up.

That shallow outer groove is 2-3mm when new. I estimate my Cup 2 wear is <1mm per track day. I got 8 days from my first set, and now I am on my second set. First weekend on them also at @pilotgore home track (Putnam), and only the front right has any of that groove left.

I hope for at least 5 weekends on this set of tires. Maybe even six once I increase camber. Currently -3.3 front & -2.1 rear, but working on up to -4F and -2.5R.

Having said all this, I think you have at least 4 more days, provided you have a good alignment.

Thanks

Also 1mm per day is useful since the tire starts with about 7mm.

What do you all think about how old the tires are? I still have my original set from my 2020 that have been stored indoors, they look good, no cracks.

I think you should be good.

I have been running 2021 and 2022 with no issues. Next set on deck is 2024, double bagged on the shelf, not climate controlled.

I think Michelin says 5 years as long as it’s climate controlled. As the rubber ages it becomes less pliable. Even though you aren’t seeing cracks, it’ll likely be less sticky and might chunk faster than a fresher tire. If you aren’t pushing 10/10’ths, sliding around, you likely won’t notice a difference.
