[urq] [WT-Audifans] Road Force Balancer

[B Vibert]

If the imbalance problem is simply a function of weight, then you can 
correct for it.
However If your tire is thumping or pulling  or oval shaped because of a 
manufacturing flaw, then this machine can tell you and you can stop 
diagnosing and blame the tire as being the culprit.

You can have a perfectly balanced egg shaped tire.  You can also have a 
perfectly round tire that under load acts like an egg shaped tire.  
Neither will give you a very good ride.
