      Tire noise or something wrong?

      I hear a "hum" coming from under the car when turning left or right greater than 60 degrees. There might even be a light thump thump as the wheels turn. I feel nothing in steering wheel. I never hear anything driving straight. I also tested when stopped by turning wheels full left then full right, no unusual noises.*

      Does this sound like something is wrong with my new 2020 XC90 T8 or do you think it's just typical of Pirelli Scorpion Verde All Season tires?

      Only way to find out is to go to the dealer and drive another xc90 with the same tires

      Tire noise or something wrong?

      How loud is the hum and how many miles on those tires? I had a slight hum but going straight or turning ,went away. Yours should be checked as turning hum remind me of wheel bearing, but on a brand new car? Unlikely

      No to both. How's the cold tire pressure in all four tires? Hopefully an easy thing to check and eliminate.

      Thank you @likeXC90, you were correct! Apparently dealer filled 12 PSI below recommended tire pressure and set it (I think they do this to soften the ride during test drives). I pumped them up to recommended and the noise went away.
