I agree with above posts, but want to add a general caution regarding buying ANY non-name-brand automotive products on e-Bay. I've not had good experience doing so, and I think my experience is typical.
I'm not saying don't do it, but ask around. No amount of wheel balancing in the world can overcome the vibration from an off-center hub in a cheaply-made rim/wheel. Good luck!
