King rims 7x15H2 on Opel Kadett E

Good day, I found a set of King rims with KBA number (Yes, found) and would like to drive them on my cadet E. The thing is that the rims according to my “research” were intended for the BMW E30 and thus have a larger scar diameter (for which there are centrings) What I come to the actual question, can I drive the rims LEGAL on the cadet? And if yes (from where I come from) I need some papers for this or can I just use it for the TÜV nozzle n and have them entered? Please find more information about the rims in the pictures I am looking forward to helpful answers
