"Did you have them spin balanced?"Yes, at two different places.

"might want to check for bent rim"
Already done this using my dial indicators, same ones used to find the .090 high spot on the one tire

"replace the BFG's with Kumho's"
Kumho doesn't have a tire in the size the front calls for, however if the next step doesn't work I will try different tires.

"Try having the tires "road force" balanced"
Today I was talking to a younger churchmember that also runs a repair shop. He has one of these machines so I'll take the tires to him next week.
