 Question: The heavy lugs of these present treads have a noticeable, ALMOST
 cupping-like offset that makes them feel like a rough surface when you rub
 your hand along them. They are properly inflated, properly installed and the
 front end does not pull to either side. I've driven behind the van and
 there's no noticable issue with camber, etc. But the treads feel like a
 Vibram sole bent into a sharp arc; they are blocky. This has to have
 something to do with our extraordinary noise level, but does anyone have any
 suggestions? A simple balance and rotate, maybe?

I had a similar issue on a different vehicle. The dealer balanced them 3 or 4
times with little benefit. Finally he balanced and rotated, they got way
better and still are after about 5k miles. Worth a try and you can even buy a
lifetime balance someplaces.
