The tire wear description fits not being aligned after the box got put on the bare chassis. Additionally spring sag, adding weight and wear can also cause alignment shift toward toe out and negative camber.

Few are lucky enough to get a good alignment shop that really knows how to properly align a van or delivery chassis that's always at maximum compression.

I've had good luck with E series chassis alignments when specs are biased toe in and 0 camber. But the real discovery was maxing out positive caster and most shops don't offer correcting this unless it's way out. I doubt you'll even find a sleeve that will provide too much caster.

Personally, when you get new tires have them put metal dually valves on and use a truck type air chuck for filling and checking. Just makes things simpler for the long haul.
