After 20K low impact miles, an attandent at a parking garage noticed that all four flat run tires on my 2002 SC430 were showing a metal band on the interior edge of the tread of each tire. I would never have noticed this as it was only on the inside tread and was only viewable when the front wheels were turned hard. I immediately took the car to the Lexus dealer where I was told it was an alignment problem. I basically had to pop for 4 new tires and the dealer comp'd me on the alignment. I must say that I drive this car like a baby and I can only assume that the mis-alignment must have been a factory issue because I did nothing to cause all four wheels to go out of whack. I'm curious is anyone else has had a similar experience. Other than this, it's been a great car and I love it.
