delamination of front tires

2011 Nismo#91

Assuming that's the outside.
That's what happened.
But anyway, some tracks eat tires more then others. For example one of the close by tracks, NJMP Lightening, will destroy left tires because it has a number of high G right handers and the pavement is very course. Especially the final turn called the "bowl", it's a fast long banked right, I usually do an average of 80mph at 1.2g or so.

You need to stay on top of your tire pressures too. Just knowing your starting temps is good but you need a lot more information, they may be going up to 40+ at the end, you don't know. Measure before, after, and if you can during; have someone measure your times in the pit lane one session. Depending on the situation I could gain almost 15psi from cold start to mid/end session.

Also what's your sway bar and settings? That has a lot of impact on weight transfer and wear.

Final thought, at the track you can just switch the tire sides when it's getting really worn. Yes it will be reverse direction but you'll be able to get a few more session where even if you won't be putting the best times down you can work on technique.
