I agree with the guys about this being the only type used for many years other than the one which spun the tire on the car which is what the current dynamic types tend to replicate. But you can't replace the installed process if you are a purist. I have a bubble balancer and here is what I can share with you. Flat concrete garage floor best.
Calibrate the unit prior to installing the tire
Remove all old weights, dirt and other "things"
Insure the tire is centered on the balancer...very important.
Put weight on side having bubble
Balance and lay weights around perimeter of wheel edge accordingly....don't install yet. If you have weight on opposite sides (across the wheel not top and bottom, same side) of the tire your initial weight was too heavy. Half weight requirement and put half on the top and half directly underneath on other side of wheel (not across to the other side, under the weight you are installing on the top side). Install weight insuring that the weight conforms to to the curvature of the wheel. Here's the tough part. Remove the tire/wheel from the balancer and reinstall it. If you did your job correctly (both times) the bubble will be centered. If not, back the truck up and do it over. If you are not satisfied with your static balance and have a stubborn tire you may then want to take it to a tire shop with a dynamic balancer. One final thought. If you use a very large weight [(say 4 0z on a LT 245-16)..depends on size and wt of tire wheel assy as to what is large] you may have a heavy spot on a tire lined up with a heavy spot on the wheel. Break the tire down and rotate 180 degrees. Sometimes this helps. Remember less is best on weights. txblu
