Snoopyy

I bought 1.6 petrol (of december 2019 with 58k km) a month ago an this sound is driving me crazy... 61 pages and no effective solution. I didn't notice this problem at the moment of the test drive, that time there were backseats that were making a strange noise but the dealer fixed it. I have the station wagon version, i tried to pull out the weel from its well but nothing changes, also lowered tires pressure, it helped a bit but when concrete is not good it's a pain to be inside the car.
