When to use winter tires
Since Dec. 3, 2010, a German federal law has been in effect that specifically mandates the use of winter tires when conditions are icy.         
                        
Winter tires have two kinds of markings: A snowflake for snow tires, or “M+S” for tires designed to work in “Matsch und Schnee” (mud and snow). All-season or all-weather tires may also have the “M+S” marking and are acceptable for winter driving.             
                                        
The law also applies to motorbikes, trucks and buses, regardless of whether the driver is the owner or is renting the vehicle.

Most German motorists have long known the old rule of thumb for putting snow tires on the vehicle: “von O bis O,” meaning “from O to O.” It is short for “from October to Easter.” It is a recommendation that one should make the change from regular tires to snow tires in October, and leave them on until Easter.

Only snow tires without spikes or studs are allowed in Germany. Tires designed for snow function better than multipurpose tires. All tires should have at least 1.6 millimeters of tread depth, but for maximum safety, tires with less than 4 millimeters should be replaced. 
                   
Winter tires offer better protection than all-season models, and it’s best if all four tires match. The German automobile club ADAC recommends using tires that carry the “three peak mountain” seal, the mark of snow tires that meets the highest standards.

If the police catch you driving in winter conditions without M+S tires, you’ll have to pay a fine of €40, plus a point against your license.

If you are involved in an accident or you block traffic in icy conditions without M+S tires, the fine goes up to €80, including a point against your license.

In addition, some insurance companies may deny coverage to motorists driving with summer tires on winter roads.
