Funny tire wear issue

[Secret Ag]

Got a 4.8is and I am seeing tire wear like you would expect with always being over inflated tires, but I have always aired up the tires to the psi listed on the inside of the door.

I am running Michelin Diamaris currently and only have 10k miles on them but the middle of the tire is already bald. Inside/Outside still has plenty of tread.

Anyone else have this problem? What psi do you keep you tires at and what to you currently have?

Finally found a similar thread to what I am seeing in the search.

Any other responses would be helpful but it looks like I just need to go to a different brand

overpressured?
