At the speed the tire is spinning on the balancing machine it won't show. It'* probably only in a small area and requires the speed with the weight of the vehicle loading it to the ground, thus applying more pressure to the affected area.
In other words, the slow (5-15mph) speed that the wheel is attaining on the balancer doesn't really give the best balance....as in exposing small ply/belt seperations under such conditions.
Hope you understand what I'm saying.
