Well you are not alone. I got 17k on the first 2 sets of tires. The tread wears out on the inside only. Park Place gave me the same run around. And I griped because first they balanced and rotated the tires and aligned and said the vibration problem was fixed. I'd drive it home and call them and they would say it needed new tires. This last time I got a copy of the alignment print out and the next week when they repaced the tires they aligned it again. Totally different numbers. I showed both sheets to my saleman ( this is lexus #5) and he got a technican. They told me they were having trouble with one of the aligment machines and wern't suposed to use it til it was fixed. I asked if they we going to call anyone who recently got an alignment on that machine ( no answer). I called Lexus in CA and told them I didn't like that and did not hear back. A week or so later I called CA again and the rep there told me he had called PP and talked to them. The up shot was PP said the conversation never happened.
I told my sales rep that there is a reasoon Lexus has dropped from 1st to 5th in consumer reports and this is it. no followup on their part or anything.
