Inner Tire Wear on front tires

Hey All

I bought my 08 Mustang last April. It had stock pirellis on it and i noticed they were bald on the inside up to the inner tread bar on both front tires. I had the suspension checked and ball joints and also had the inner tie rods replaced. I had 3 alignments and also had my tires balanced more then once and rotated. The tires i have now are good years eagle f1's . Still wearing uneven. Anyone else had to deal with this mystery problem? Thanks

Yes i think they were actually. CJs Tire did it. i went to 3 different CJ's tires though. It should have been corrected right? I spent like$ 950 on tires and the front ones are chopped inside. i dont want to have to buy more prematurely if i dont have to.
