11 October 2021, Berlin: A mechanic at the Krause car service workshop in the Lichtenberg district changes the tyres on a vehicle from summer to winter tyres. The rule of thumb for seasonal tyre changes is: from A to O (All Saints' Day to Easter). If you have an accident with summer tyres despite bad weather, you will pay high fines (winter tyres are compulsory). Automobile clubs in Germany advise an early change, so that there are no long waiting times in garages in the event of a surprise onset of winter. Winter tyres are most effective when the average temperature is below seven degrees Celsius. Photo: Wolfgang Kumm/dpa
