I have never been able to get the beads into my tires.
Two other ways to balance.
1: Do it yourself using a HF balancer. I have been using this for years and works out well.

2: The other way is to bring the mounted tire and rim to a tire company that has the mounting equipment to do a high speed tire balance. I have also done this and it works well.
