I'm having a similar problem on GS 300 - 1999 . ARe your tires OEM? Type of drving may be a factor.I drive 80% Mt roads . been told this is hard on tires. See my Post Noise after 10K.. My tires appear to cup on the outside .. air presurre good.. alignment good.. ect..

I have new Goodyear Eagles. after 10k miles - road noice was un real.. Growling as a came to a stop.. Moved front tires to rear.. much better....Tire problem..I checked air all good.. cupping on tires or something.. Are these tires too soft foe the car. Lexus dealer stated MFG uses Michelin or Continentil . Any suggestions
