As I have some freetime right now I was surfing the net and found these tires for the F103 (scroll a little):

I found a shop in Germany that says in the description that they will also fit on the F104.
Does someone have experience with these tires or can tell me if F103 wheels will fit on the F104 (v2)?
Thanks
