Quesiton is, What is causing my tire to be worn more gradually in the middle towards the inside? I dont daily drive on this setup as i switch couple days before track. My first track day i drove with 40 PSI hot all around. My second track day i tried 38 PSI hot all around but drove the car much harder the second time around as i was more comfortable. What can be casuing the middle to inside to wear much faster?

Thanks
Tire pressure is too high.

Do yourself a favor and get a pyrometer. I can teach you how to use it (or google).

Outside high = need more camber
Inside high = need less camber
Center high = less pressure
Center low = more pressure

You want a 10F or less spread for simple hot lapping. Racing or time attack may warranty a different spread.
