I tried to drop the psi down to 31 from 34 around 8000 mile mark on the rears (thinking it was over inflated) with no luck. any ideas and suggestions? Anyone else using these tires and care to share how many miles you get out of them, psi, and any premature wear (i know our cars comes factory with -1 camber)?
I do spirited runs, but that shouldnt cause premature center wear.
Thanks for your input

I've also seen this happen on tires that were mounted on rims that were not wide enough. This causes the tire's sidewall to angle in farther than normal and this makes the tire "bulge" in the center. No amount of air pressure adjustment will fix that. I used to work in a tire store like a hundred years ago, so I have seen this many times when people try to mismatch a rim and tire. Don't know if this pertains to your situation, but I thought that I would throw it out there.
