High-quality load-bearing index allowed in principle?

Hello together, as soon a new set of summer tyres is coming up for me I have a little question about the load-bearing index accordingly. May the index be basically higher than the registered one? Is there an identical wheel size provided of course! From the search I did not become quite clever. It was rather about the opposite. Wikipedia also did not really help me further, because there for tyres for more than 210 (in my case V) apparently a special regulation applies with regard to the load. If someone could give me a quick look at the index.
