Road Force Balancer: Difference between Normal vs. Road Force vs. Road Force Harmonic
From reading through threads, it seems like the Road Force Balancer by Hunter is the most popular machine out there for balancing wheels. I called American Tires (a bimmerpost forum member had good experience there or normally I try to avoid chains - OT) and he offered me 3 different choices.
$15 for "normal" balancing using the same Hunter Road Force Balancer as the other 2 $20 for road force balancing $25 for road force balancing with harmonics What exactly is the difference between them all? I was not aware the machine had different settings… anyone familiar with tire balancing able to give a suggestion on which balancing method to use? |

Simplistically balance a tire mean you are ensuring that the heaviest spot in a tire/rim combination are "balanced" by adding weights to the opposite or lightest spot. Thus effectively if the tire/rim combination are setup on a "Frictionless" axle and tuned to any position the tire/wheel combination will not be affect by gravity - ie the wheel will not rotate.
The road force (RF) balance and RF+harmonics take into effect the minor out of roundness of the tire and stiffness of the tire. Here's a reasonably good explanation of the RF and RF+Harmonics associated with balancing tires for your reading pleasure. http://classic.artsautomotive.com/GSP9700.htm http://www.barrystiretech.com/unifandbal.html The Road force balance is usually acceptable unless you spend extended time at AutoBahn speeds.
