How to find reasonable tyre dealers/monteur?

After my last tyre dealer screwed up a set of aluminium rims (3 of 4 rims with scratches/damages from the tyre, prints in all rims because the rims were tensioned without protection from the inside) I am looking for a new operation again. Unfortunately, I have already had bad experiences with various companies in the past (conical band screws in ball bundle rims, various damages). I seem here in my surroundings i no one is able to raise a 225/40 R18 or 235/35 R19 tires (no Runflat) accident-free. Also, only the absolute minimum work is done. I deliver 4 brightly clean rims with old tires and not even the adhesive residue of the force weights are removed. I always do the change between summer/winter tires myself, but at the latest when you need new tires you are dependent on someone. How do you choose your tyre dealer, or can much Does anyone recommend what in my region (southern Emsland)? Do the contract workshops do what when it comes to tires?
