Most tires start with about 6-8/32nds of tread and for race conditions get shaved down to 4/32nds . So assuming you still have wear bars, you should be good for a little while yet.
Here's an article that might help..

Until the tread is below the wear bars. No real limit to how long they will last, street tires don't heat cycle out as much ar R compound tires, they will get a little faster as tread wears down and gets more stable then will slowly slow down as wear passes 2/3rds If you have tread you can run them, they just aren't quick. I ran about 1500 track miles on my PZeros and still have the rear tires mounted for street use. A set of Continental Slicks gives me about 8 sessions (250 miles) of good lap time and another 6 sessions of fair times until they cord. Contis are about 2 seconds a lap quicker that Michelin Pilot Super Sports for me. It all a trade off, once you try R compound or Race slicks you won't want to run street tires, getting point bys is more addictive then giving them.

I ran my P-zero's down until secondary rubber was showing on the outer edges. The more they wore down the more traction they had on the track. I did not get many miles on them as most of the miles were track miles.

Secondary rubber on edge. Do you have any pictures? Mine wear out much sooner on edges, but I'm not exactly what to look for.

No pictures but secondary rubber can be seen as the color of the rubber changes. Just under the secondary rubber is the cords. I run 2.7 degrees of negative camber also, which will help the outer tire edge wear.
