Hummer H2 rims/tires TÜV registration

Moin dear community, my brother-in-law and I have been running back and forth for a good three weeks (except for the holidays of course :-D) from tyre dealers, werkrstätten and Tüvler, and I don’t come any further. I had often heard that the high-weakness of the Tüv employees is hardly to be surpassed. But I have experienced it in the last three weeks at my own. So, genung wailing, now to our problem: My brother-in-law bought a lobster H2 here in Germany about 4 years ago. (with new Tüv) and exports him to Latvia. There he drove with it for 4 years and now he is finished with his work there, and returned. Customs with VAT we got the lobster there without any problems. It is problematic now with the Tüv. They do not accept the tyres (rightly). Because he drove over there with 22 inch Ami rims (which rotate). Here he will not get such rims registered according to the forum. My proposal was now that we over the bay a few We also found some original rims. Only before we buy them, we would like to know if we could easily get Tüv or not. Because one said to us at the Tüv, without an expert report it won’t work. The other resisted, expert report would be second priority for the time they are original rims. And where should we get an expert report from? Write GM? We would really be happy about a few help points so that we can buy them next week. Have a nice Friday… 🙂
