Took Skippy the dog’s advice. Used ceramic beads. A world of a difference. I guess they just have trouble balancing these rims
There ya go.....It didn't sound from your note that the wheels were bent much, if at all.....I wonder if the previous owner just gave up on this out of sheer frustration w/ the balancing? Perhaps the rims were never really bent at all? This would have been a simple thing for the rim supplier to explore and report on.
The only very minor annoyance I've experienced with the beads is a slight side to side (dynamic balance) wobble at 30-33 mph. I surmise this is where the beads start "finding their home"...Accelerating slightly mitigates this and I do not notice it upon deceleration through that speed range......
I have a few more theories on improving that but will reserve those thoughts for now....I'm a former factory Porsche tech, service advisor, service manager (Toyota/Subaru/VW), Sales rep/trainer for the now defunct Bear Auto Equipment Co. and MAC Tools dealer, so I've got a few people whose brains I can pick as I'm one of those guys that knows a little about everything and a lot about nothing (per my ex gf)....though I may not implement any of my theories until I'm due for tires again....
