The lower control arm bushings can wear and crack, resulting excessive movement at the control arm pivot point, leading to irregular and premature tire wear. Worn Ball joints can also cause similar tire wear symptoms. I some cases it may be necessary to replace the lower control arm, including bushings & ball joint to correct this concern.
Premature Tire Wear Due to Cracked Lower Control Arm Bushings on Mercedes-Benz S600

I have non-passable tire wear after only 11,000 miles. This seems a bit extreme. I don't know if it is a lower control arm bushing problem but it is unreasonable to expect new tires after 11,000 miles!
