4,5" x 15 Fuchs Wheels

I'm about to look for a bit more detailed info about my Fuchs wheels. I can't find any info on the wheels themselves apart from the numbers on the pic (25205.3 and 4,5J x 15). But these numbers seem to be 'ungooglable'and are not mentioned e.g. here. Do I miss additional numbers somewhere on the wheels? If you know more or better websites regarding this please leave a comment. Cheers!
