Drowning while giving gas and funny crazy tires

Hello dear Volvorianergemeinde! After a long time I actually had no reason to excite myself about my V70III D3, it comes now quite unpleasantly thick. It started with unusually worn tires on the front axle. On the driver side the tire is almost blank on the inside and on the passenger side there is, also on the same width inside about all 20cm a blankly driven piece of tire profile. But round around. So that the chassis does not feel so alone, have, perhaps out of sympathy, two strange noises from the engine room joined to it. It sounds like such a kind of hollow throttle – or flaps. The second noise comes always when I make the car look good at about 1000 rpm and when driving at higher speeds. I had already seen whether there might be somewhere a disguise or a box open or loose, but could not find a nice rest of it. The second noise is always when I put out the car after a longer ride and place it at higher speeds. It seems to be from the driver’s upper part of the engine room and there is a nice rest of it all.
