2004 LS430 with 5/32" tread depth across the rear tires (38,000 miles). Car felt a little squirrly so I had tires pulled off and found left rear so worn INSIDE the tire, next to the tread area that there was a 4-5 inch split with steel belt showing. I had the place (independent) check alighment and it showed some beyond spec situations on the other three tires. Left rear was enormously out of camber specs. They pressed me to buy a set of tires but I didnt feel comfortable with them and drove to Lexus, where another alignment was done. Their printout indicates very different alignment specs. I'd like to find out what is going on. Can anyone tell me where to go to find the official alignment tolerance specs for my car? As an aside, independent told me there was no way to adjust rear tire camber on the car. Lexus dealer verified that but installed new lower arms to correct the situation. Any help here would be appreicated.
