I own a 2008 RX350. Let me start by saying I have Hankook tires. They are extremely loud. When I make a turn, I can't figure out if its the tire, or the mount thats making a noise. Considering how loud the tires are, and its time to replace them, I keep wondering if the tires are making a weird sound by the aggressive tread. Does anyone else with this vehicle have weird sounds when driving. I travel as a sales rep so I put alot of miles on this car. To be honest, I used to have a Toyota Tundra, and it was quieter than my Lexus. I have been a little disappointed with this car. I though Lexus vehicles were extremely quiet. What I want to know is it the tires? I've been told the Hankook tires are awful.
