When I got the last oil change at our local Meineke, I asked the guys there if we could find a replacement wheel that they could put on. And they directed me to Wheels America.
Rather than buying a new wheel, they were able to repair it and eliminate the ding. I had to get the tire taken off at Meineke and take the wheel over for repair myself, but the next day, I got the wheel back, took it back to Meineke, and things appear to be as good as new. With any luck, those annoying leaks will be a thing of the past.
Total cost: about $130 to Wheels America and about $33 to Meineke.
I can work with that. :)
