They’re crazy about the TÜV inspectors

Hello for the first time, was just for the third time because of my rims at the TÜV and wanted to have them with tyres of dimensions 205 R something 55. In the ABE there is only one release for tyres of size 205 R something 50. The examiner says: impossible. If I look at what others drive around with (tires under the wheel box etc.), it can’t be that I get no acceptance because of 5mm too high tires! These sticky laws make me crazy. they still get registered, don’t they?
