... how much tread left on the current tires? possible wheel bearing?

 

well , ive installed 20" audi a7 oem wheels. now the noise is more like a high pitched harmonic noise from 60 to 80 mph . the sounds is a lot quieter and less pronounced but still there. it is over a longer mph range now
i can very faintly feel in steering wheel
20" Michelin tires 255/35/20 brand new .
thank you for taking the time to answer , i appreciate it
