My 2002 Camry has eaten 5 sets of tires in 138,000 miles. I have figured out the problem. I believe the front right strut assembly was mounted out of alignment at the factory! Camber has never been nor can never be properly set. It is a factory defect. I'm going to Toyota Monday with proof.
If they cannot or will not fix the car, I plan to suit both the local dealer and Toyota.
If your Camry is eating tires, even though you rotate, inflate and align as-needed you might have the same issue.
Will post results of the visit to Toyota. And this is no joke. Look at your last alignment readings. If you see the camber is out of range or at the edge of range then you too may have purchased a factory defect product. Email me as needed. Go through your paperwork from repairs, tire purchases, alignments, etc. Gather your ammunition because Toyota may fight back.
