I've heard of "road force" balancing and it's supposed to be a better method, but I've never had it done myself. I don't believe anyone around here does it.
BTW when I took my tempo in to have tires put on it (with the stock steelies) they told me all four rims were bent, but the car drove fine with no vibration. Then one day I got a flat, they plugged it, and now I get a vibration somewhere in the neighborhood of 65-75 mph from whatever end of the car that tire is on. They rebalanced them twice and then put that tire on the back so my steering wheel wouldn't shake
I would think they could actually balance the damn thing even with a plug in it.
Wheel problems 
So I am taking the wheels/tires back by there this afternoon and see what they say. I'm thinking that when they balanced them they should have known something wasn't quite right. I'm giving them one more chance to make it right. Getting kind of old haulin them over there and then putting them back on car to check. This will probably be the last time I try them again.
Took it out for a test drive. Slow speeds don't seem to have the hop that it had before. Got it up to 72 (in a 55 
) and it seemed to be a lot smoother. The shop used the Hunter GSP9700 RoadForce Machine. It's like a $17,000 machine that the owner said they don't use unless the customer asks them to use it. It does cost more than a regular balance. Ended up costing me $64; initial balance and roadforce together.
