As long as the tire is mounted correctly on the wheel and the bead line runs straight with the wheel lip and the tire is round, a computer static balance with weights on the inside is fine. This is why all modern spin balancers have a static setting. Although it does require that the tire run very true and you may have to break the tire down on the wheel and "turn" it on the wheel to get it to run true, once that is accomplished, a good static balance is sufficient.
