Thanks for the contact, Chuck. It looks like the Poway and PB stores have a RFB machine. The last time I went through this process I had the wheel inspected by US Wheel in El Cajon as they do a lot of high end wheel repair. They said it was structurally sound in their opinion and said that occasionally, when a wheel is refinished (which these were by the previous owner) and sandblasted, if the valve stem hole is not completely sealed off then some of the sand/paint debris can get inside a hollow spoke wheel and cause a balancer to throw strange numbers. I'm not sure if it's actually stuff moving around inside the wheel or if it is compacted in one spoke and "baked" solid. Either way, they suggested to road force balance it and "chase" it. It worked...took the tech about 20 minutes of trial and error but it worked. And, there was no ill effects on the road at speed. I suppose there might be a chemical I could put in the wheel that could disolve/rinse out whatever is in there but I have not tried that yet.
I don't want to replace the rim as the fancy finish the previous owner put on is apparently a $300-400 job to replicate...for one wheel!!! It's similar to the anthracite gunmetal finish of the BMW "M" wheels. I guess the metallic silver paint is what jacks the cost up. I know this because I've already priced having to get a new wheel and match the finish.
Wish me luck (or whoever the tech is at the discount tire I go to
)
