I'm looking to do my first track day, and the group I'm signing up with has a self tech form. They ask if street tires have more than 2/32" of tread. I have my OEM Cup 2 tires still (less than 3k street driven miles) which I'm sure you all know, have very shallow tread as is. Will I be ok with these tires?

Thanks!

Tire Rack says those tires have 7.2/32 when new. I'm not sure what the wear bars measure at, but if you're down to 2/32 or less, they're probably about done. And maybe you'll get away with 2/32 if it's dry, but if it rains, you'll be sitting in the paddock while the operator counts your money.

Autozone sells tire tread depth measuring sticks for $3 or so. That would be the easiest way to tell

July in the desert of LA, don't think there will be much rain lol.

For tires, if they’re getting low, check for cords after /every/ session and make sure to check the inside shoulders. Pay attention to odd noises, ‘balance’ issues, and grip Falling off, as any of those could be a sign you’ve corded a tire or have chunked one. Better to pit for a quick check then push on.

If your tires don’t survive the event, don’t expect a refund from the organizer.

Lots of experienced people will run tires low and replace them at the event with spares they brought with them.
