Well the manager that was trying to work them out mentioned that he thought one of the wheels had a smaller bore size than the others but I ran calipers on them and that's not the case, so who knows. All I know is that they ran perfectly well for 5-6K miles then they re-balanced them and it was never the same, it all went to hell and they just kept throwing weight at the problem making it worse and worse each visit. At the end of the day I got new tires for no money out of pocket and things are better, hopefully they stay that way.
Take a look at my added edit above in case you missed it.
In any event, glad you finally got it sorted.
