Unusual tire wear (stock Bridgestone Duelers)

Hey guys.. just wondering if you've seen this before? I've got the factory Bridgestone Duelers with 19,650 miles on them.. and for the last 3,000 miles or so my front passenger side tire has deteriorated tremendously. I assumed it was my alignment, and with my lift and new tires going on in a few weeks I just said f*it.

However, I went in for my 20k service at the dealer this morning and when I pulled in they said for certain I need an alignment and indeed the tire is in bad shape, so I said do whatever you need to do, except don't bother replacing the tire. Fast forward 3 hours... The tech said my alignment was well within factory spec, and that they didn't touch it, everything on the truck is tight and where it should be. They couldn't explain the odd tire wear.

My concern here is when I put on my BFG KO2's with my lift .. I don't want them to meet the same fate these crappy Duelers have come to!

Any thoughts?? Here is the worst tire and the alignment report.

 

and get your camber both positive and closer together. Preferably around .2*. Camber being that different left and right will usually create a pull.

 

The OE Duelers are hot garbage. I can wait for my wheels to come in so I can upgrade.
