Would you say these tires are still good for a track session?

Track aficionados, what say you about these tires... still good for a track run? I see no cords yet...

are you kidding?
Is your point to drive them till they show cord and you squeeze every single penny out of them with basically no grip? If so, keep on running them.....

why do you think they have too much camber? are they not cup 2's? that looks like normal wear for cup 2's to me... and yes, OP didn't mention if they are cycling out or not, just asked about the wear. if lap times are falling off and/or the car is hard to drive then sure get new, but for hpde i want to use as much of the tire as i can.

from what i've been told. the front gets worn out before the rear when you're tracking. as far as grip goes, their cup tires so the grip continues to remain there. the only time you'll have a problem is if their is rain. you'll be parked on the side for a good while. haha.

They look like normal cup 2 track tires to me.

Me, personally, it depends on the track. A high speed course where delamination would end you would warrant a new set of tires. Some of these other tracks, heck, continue run them all day long.

It just depends.

Did you use a pyrometer and measure the inner to outer temp ratios?

Would you trust this one?

Or would you support one from Summit racing for a bit more? Can you also elaborate on the delamination at high speed?
Hell no, that is a kitchen IR thermometer. You need a probe pyrometer that inserts into the rubber to get an accurate reading.

Let me see if I can find a link to the one I use.

Side note: temperature readings need to be done immediately after about 4 or 5 hot laps to see what is going on with the tire.

Elaborate on a high speed tire delamination?

Let's see. If you are lucky, you will be able to maintain control of your car. Then comes the disintegration of the tire and it begins to tear your car apart (fenders, wheel well, etc). Furthermore it throws debris and shrapnel all over and effects others who have been driving near you.

If you are not so lucky, you probably hit the brakes like a scared little school girl and just compounded your problem. Chances are before you have any idea what happened, you are sideways and spinning towards a concrete barrier. Well, then, you know......

Solution? Step on the gas to counter incurred upon drag and deal with the driving asymmetry. Keep going straight until you can safely bring it to a stop. However that option isn't always available..... easy for me to say, eh?

Rear looks good. Fronts might not last the day. How many heat cycles?.
