Wheel Vibration is another endless unresolved thread. Causes of Vibration problems and Algorithm as I see it:
Nice section here Mike D.
Another factor that may cause this result for me was the fact that my wheels were all trued (cut perfectly round). I have a very good truck tire center here in Pensacola, who does all the Guard tirinstallation etc. They have a great method of balancing wheels with CTIS.
Another important factor, is to make sure you have the CORRECT type and quantity (flat and lockwashers) washers that fasten the CTIS cover plate to your wheel. The CTIS cover's center of balance is actually .5 in. away from the center of the wheel (really, next time you have your plate off, balance it with a flat screwdriver and see), so it is important to have all the correct hardware on the wheel to ensure that plate is somewhat center balanced. My truck is in great balance at all speeds without the balancers, I returned the centramatics and got my money back.
