![Question](https://my350z.com/forum/images/icons/icon5.gif)
I will be assisting a HPDE track event for 2 days the 17th and 18th of March. I was told we would be runing for a total of about 5-6 hours (~3/day).
I have street Khumo Ecsta MX 17".
I still have some tread left but I ma not sure if it s enough. Should I change tires before the event and waste what is left over on these (which I also use for Auto-X) or could I use them for the track event?
Here are some pictures (of the most wated, the rears) to help me determine if the tread is enough.

Keep an eye on them. Don't spin the wheels too much (just enough for fun!)

+1, they look fine for a couple track days, Keep the pressures up (40+) at first until you stop going into the corners too hard. That will help the outside tread last longer. Once you start learning how to enter the corners correctly, you can lower the tires pressure to get a little more grip.

I asked a question like this a while back, and my tires were more worn much more than yours. I would say you have plenty of tread left for probably 3-4 DRY track days. If it's wet, make sure you haven't worn your tires past the wear bars.
I'll run my street tires until the shallowest tread block is gone, but I inspect my tires after each run when I get past the wear bars. There is still a millimeter of rubber under the treads, but I don't think it's worth the risk.

Great info. I am thinking on removing the tires and have them mounted on the opposite corner since they are worn more on the outside than on the inside. First time I see opposite feathering on my car.

Hopefully this time, since I will be out there much more time, I will learn with repetition.
Any tips?

Brake harder (as hard as you can. Don’t be afraid of locking the wheels, you have ABS…) for a shorter period of time. Average brake temps will go down.
Don’t forget to release the brakes to make your turn. Don’t forget to turn the steering wheel either… (Sounds silly, but I’ve been distracted with new found braking powers once and almost went straight while enjoying the breakthrough…)
Keep the sunny side up
And the rubber side down!
