tire feathering? because you said something about the tire being more bald than the other. just guessing im a noob haha. OR maybe is it the chamber.

 

Judging by your discription of the problem it sounds like something to do with your rear tires. I personally only get my car aligned at Honda because they seem to be the only ones that can do it right in my area. I ALWAYS get the printout when they are done too so I can check the specs. And for what its worth, these cars are difficult to align properly, not that it should be an excuse...
