I balanced one of my car trailer tires on a new wheel this afternoon, it took less than three ounces using my old bubble balancer. It has a adapter that has Volkswagen and truck adapter written on a decal on the adapter. I've neve had to uses it as I got rid of my V.W. sand rail years ago and I can't mount my 2006 Ram 3500 17 inch truck tires on my manual machine so I take them up to one of the local tire stores and have them do both mounting and balancing
