We just bought a preowned Lexus 2006 ES330. When I drive through even little bummpy road I hear nose from the back. It seems that the tires touch the suspension. The dealer has put M+S P245/45 R18 tires. When I see the manual, Lexus suggests to put P215/60 R 16 tires. Is the tire that deal has put ok?
tire sizes are on drivers door sticker and most likely who had it before you added larger wheels and possible tires are rubbing any tire shop can help you find or fix problem
