delamination of front tires

Thank everyone for all the information and help. Getting to know things better even at this old age helps

I did email Falken Tire about it and here is there finally thoughts

We reviewed your tires with our manager. The isolate wear you are experiencing on the inner edge is due to alignment, specifically toe and a bit of camber. When the tires have negative toe, this pushes the tire direction towards the outside. This puts isolated wear towards the inner edge of the tire. With acceleration and shift of load from front to back, this causes even more negative toe to subject the tires.

We would advise finding a setting that minimizes this negative toe in order to maximize tread life on the tires. Negative toe helps with steering response but decreases tread life. This would affect inner shoulder wear. Positive toe or toe in helps with stability but slows response. This would affect outer shoulder wear. Below is a summary of toe settings.

Camber does affect the edge of the shoulder, however, the rest of the tire will have a progressive wear rate, from shoulder to shoulder.

Impressed with the result, and an understanding of what happen. Yea, the last set of toe was 0, now its on the positive side. We'll just have to see.

The other item is to figure out when I have to drive 300-500 miles to a track. More thinking and planning
