Tires wearing out too fast

[Action]

So, he is told his tire is wearing in the center of tread due to too much air.
He says he is running 30 psi.
Then he is told to put in more air.

Check the ball joints and radius rod ends. I know I have to replace mine when I start blowing thru tread. I replace the offending joint and the tires stop wearing. Simply out of alignment will have similar symptoms because when the joints get loose the alignment wanders all over the place.

I've put about 40k or 50k mi on my truck and replaced two sets of ball joints and tie rod ends. I've also been thru about a dozen tires, MT's and MT/R's. Mostly I shred the sidewalls long before the tread is gone.
