Did a rebalance myself using a Hunter 9500 and have no issues what so ever with my 265/70-17 BFG A/T's.
I always thought static balance vs dynamic balance had to do with the method used to balance the tire ie static means the tire is not rotated while balancing ( usually a bubble balancer ), whereas a dynamic balance involves rotating the tire on a spin balancer. It just so happens that a dynamic balance is more accurate and actually dictates putting weights on both sides of the wheel to take full advantage of the dynamic balance.
What side are the weights mounted on?
I think it would be more important to have them outboard when dealing with wider wheels/tires in order to balance out and wobble associated with extra width.
My FJ wheels with 285's were balanced perfectly by the dealer with weights on the inside.
With a modern balancer like one of Hunter Engineering's road-force models, you can set it for outside or inside weights, some wheels weren't even designed to use clip-on weights. Hunters have a laser to pinpoint where exactly the weight goes, and can even set up the balancer to hide the weights behind spokes.
