I agree 100% with Larry Bible.
Get a proper tire balance with wheel weights on both the inside and outside lip of the wheel.
You'd have to have a tire with excessive "wheel force variation" that would cause a normal tire balance machine to be unable to balance your tires.
In other words, all tires have soft and stiff spots around the side wall of the tire. If the difference between the soft spots and stiff spots is too great, wobble will develop, and a normal machine can't correct for this. A GPS 9700 can identify these spots on the tire, and show the operator how to rotate the tire on the wheel and where to put the weights. If a tire has too much wheel force variation, then it can't be balanced.
But he's right in the 90% or more of these type of vibration problems are caused by improper tire balancing.
