We just bought a 2001 rx300 and after taking it home I noticed that the alloy wheels ( especially the front wheels, have varying degrees of corrosion on the inside edges of the spokes. Nothing very serious looking, just some bubbling of whatever coating they put on the wheels, looks like aluminum oxidation when scratched. Is this a common problem, and am I withtin reason to ask for new wheels since the vehicle is still under 50K miles? I look at the wheels as I would the paint; if the paint was bubbling up I would consider that a defect.
Thanks
