While your wheels are up in the air I'd give them a few revolutions to make sure you don't have the start of a ply separation. On our old Montana I had weird tire wear happening on the street-side, turned out to be a ply sep. The front tire was way worse than the rear, put on the spare. Luckily I made it back home without incident and bought new tires!
A tip my dad gave me years ago when doing bearings was to tighten the castle nut, spin the wheel a few times and try and tighten some more. That would insure the bearings are seated properly and then back off the nut a tad.
