Just a short addendum on the tire balance issue- Be sure to check both the
rims and the tires for trueness. It won't matter where you put the weights
if the wheels are not damn round. Years ago I had an old guy in Savannah GA
true my tires ( no kiddin') using an abrasive wheel mounted on a big
electric motor- right on the car. ( happened to be my 2002) he then spun
the wheels and using a vibration sensor/strobe light device, and trial and
error to determine what weight was correct. Granted, shaving the tires
takes some miles off, but I was ready to throw them in the trash after
unsuccessful balancing efforts... ( Semperits) End result was absolutely
smooth ride all the way to 100 mph. he charged me about $30 for all 4
wheels! ( 1979 bucks...)

Hi Thom
The type of balancing gizmo you describe is only able to account for static
balance, I can tell you that some times the dynamic balance will be very
different from the static balance. The weights will be at the same point on
the circumference ( give or take) but if you stick the weights on the inside
and they needed to be on the outside you will have added to the problem
rather than reducing it, have the wheels / tyres balanced at a shop with
machine that spins them.
Graham.
