215/65 R16 on Mokka J-A, year 2016, 1.4 petrol tanker

Hello! My old man drives an Opel Mokka 1.4 petrol engine from 2016. On his winter tyres the tyre size 215/65 R16 is indicated, they are mounted on an Opel aluminium rim. In 2016 he noticed this wheel-tire combination when buying the Mokka (Re-Import Austria with 255 km mileage) from the Opel dealer (8 times tyres). In the CoC papers the size is not, but also not in the manual. Can you drive this size on this mokka? Extra registered are these nic At the TÜV there were never complaints, because it is always every two years in January and there are definitely always the winter bikes on it.
