Unbalanced, wheel bearings?

Hello guys, this is my first thread in this forum, so please don’t be too critical. 😉 I have a little question: Have a ProCeed (09) with about 68000km and I’ve noticed a strange but disturbing noise for about a week. At 50-60km/h and from 100km/h I hear a very easy “propellern” as if a helicopter was following me or something like that. It just roars and swings something! Hard to describe! Now I just wanted to ask you if that was about Unwuchth If the tyre can lie, or if it is a wheel bearing? Unfortunately, I don’t have a workshop of my trust at the moment, i.e. I am a bit afraid to go somewhere where they will exchange all sorts of things for me. Thank you in advance, nice day still! Daniel
