Anyone at a tire and alignment shop should be able to figure this out. Some things to look for include corrosion / debris that got stuck behind a wheel and is causing it to wobble even though it's tight. Ford had some cast wheels that used locking lug nuts that were so heavy, they needed to have a half ounce weight added across from it after the tires were balanced. Wheels can be bent on some older-style tire changers or from hitting a curb or pothole. They can balance out at the one speed a spin tire balancer runs at, but you'll still feel the wobble on the car. The mechanic will measure the wheel "runout" with a dial indicator to check for that.
