Questions about the end of the “time limit” for general tyre approvals

On 31.12.2024 the “already time” for general tire manufacturer approvals ends. I have driven the last years Continental ContiLegend white wall tires, which unfortunately are not registered in my papers.In my 28 year old papers – two different tire types are registered with me: – Dunlop D402 F Touring Elite II – Metzeler ME 88 Marathon Ok, the Dunlop flaps still exist in exactly this name. h replaces the Metzeler ME 888 Marathon. Do I simply smell this successor tire, or do I have to register it? Speaking of registration. How does this work? Do I just drive to the TÜV with freshly assembled tyres from other manufacturers and they enter this in my papers and give me permission to do so? If so, what does the fun cost about? Fun on the edge: Who knows the company Bunlop? [see picture] 🙂 Thank you in advance for your efforts!
