See how Tires appears in realistic driving situations relevant to Germany. These examples explain correct behaviour, safety implications, and how Tires connects to German driving theory exam questions.
You are driving on the German Autobahn at high speed, and your tires are slightly underinflated.
Reduce your speed immediately and find the nearest safe place to check and correct your tire pressure.
Underinflated tires at high speeds generate excessive heat due to increased friction and flexing, which can lead to tire overheating, delamination, or a blowout, posing a severe accident risk.
It's late November in Germany, and the forecast predicts snow and freezing temperatures overnight. Your car is currently fitted with summer tires.
Arrange to have appropriate winter tires (with the Alpine symbol) fitted to your vehicle as soon as possible, or avoid driving if winter conditions appear.
Germany has a situational winter tire law. Driving with summer tires in snow, ice, or slush is illegal and highly dangerous, as they lack the necessary grip and braking performance in cold, slippery conditions, leading to fines and potential liability in an accident.
You notice that the tread on one of your tires is significantly worn down, and the Tread Wear Indicator (TWI) bar is flush with the tread surface.
Replace the worn tire immediately, or have it inspected by a professional to ensure it meets the minimum legal tread depth.
A tread depth at or below 1.6 mm is illegal in Germany and dramatically reduces the tire's ability to displace water, greatly increasing the risk of aquaplaning and extending braking distances, especially on wet roads. It also impacts overall grip and stability.
Learn about the importance of tires for vehicle safety, legal requirements in Germany, and how to maintain them. Essential knowledge for your driving theory exam, covering tread depth, tire pressure, and seasonal changes.
Vehicle tires are the only part of a car that makes direct contact with the road, making them fundamental for safety, handling, and overall vehicle performance. They are engineered to provide traction, support the vehicle's weight, absorb bumps from the road, and transmit steering and braking forces efficiently. For anyone preparing for the German driving theory test, understanding the various aspects of tires—from their types and markings to legal requirements and maintenance—is crucial.
German road traffic law, primarily the Straßenverkehrs-Zulassungs-Ordnung (StVZO), sets clear standards for vehicle tires to ensure road safety. Adhering to these regulations is mandatory for all drivers in Germany.
One of the most critical legal requirements is the minimum tread depth. In Germany, the law dictates a minimum tread depth of 1.6 millimeters across the main grooves of the tire. Driving with less than this can result in fines and, in case of an accident, significant legal consequences and insurance issues. While 1.6 mm is the legal minimum, many experts, like the ADAC, recommend a minimum of 3 mm for summer tires and 4 mm for winter tires to ensure optimal safety, especially on wet or snowy roads.
Maintaining correct tire pressure is vital. Incorrect tire pressure can lead to:
Vehicle manufacturers specify the recommended tire pressure, usually found on a sticker inside the driver's door, fuel filler cap, or in the owner's manual. It's important to check tire pressure when the tires are cold.
Germany has a situational winter tire requirement. This means that if wintery road conditions (black ice, packed snow, slush, ice, or frost) are present, your vehicle must be equipped with appropriate winter tires. This regulation applies regardless of the calendar date. Winter tires are typically marked with the "Alpine symbol" (a snowflake within a three-peak mountain), although older M+S marked tires (without the Alpine symbol) may still be permissible until a transition period ends. Driving without suitable tires in winter conditions can lead to fines and a point in the Flensburg traffic penalty system. If an accident occurs due to inappropriate tires, it can also lead to partial liability and insurance problems.
Generally, it is permissible to use tires from different manufacturers or with different wear levels on a vehicle, as long as they meet the legal requirements (e.g., tread depth) and are of the same type (e.g., all radial tires). However, mixing tire types (e.g., radial and diagonal tires) on the same axle is strictly forbidden in Germany. While it is technically allowed to have summer tires on one axle and winter tires on another, it is highly discouraged for safety reasons as it significantly impairs vehicle stability and handling.
Understanding the different types of tires helps drivers make informed decisions for varying road conditions.
Designed for warmer temperatures, summer tires have a harder rubber compound that performs well on dry and wet roads without snow or ice. They offer good grip, stability, and lower rolling resistance in typical summer conditions, contributing to fuel efficiency and reduced wear.
Winter tires feature a softer rubber compound that remains flexible in low temperatures, providing better grip on snow and ice. Their tread patterns have more sipes (small grooves) to bite into snowy surfaces and effectively displace slush and water. In Germany, winter tires must carry the Alpine symbol to meet the current legal requirements.
Also known as all-weather tires, these are a compromise between summer and winter tires, designed to offer acceptable performance year-round. Modern all-season tires with the Alpine symbol can fulfill the winter tire requirement in Germany. They are a practical option for drivers who experience mild winters and have low annual mileage, avoiding the need for seasonal tire changes.
Tires have various markings on their sidewall that provide crucial information about their specifications and manufacturing. These markings include:
195/65 R 15. This indicates width (195 mm), aspect ratio (65%), construction type (R for radial), and rim diameter (15 inches).0323 for the 3rd week of 2023).Understanding these aspects of tires is fundamental for every driver, not just for passing the German theory test, but for ensuring safety and compliance on the road.

Get clear answers to the most searched questions about Tires in German driving theory for Germany. This FAQ explains the definition, real exam context, practical meaning, and common learner doubts to support confident theory test preparation.
In Germany, the legal minimum tread depth for vehicle tires is 1.6 millimeters across the main grooves of the tread. However, for enhanced road safety, especially on wet or snowy surfaces, a minimum of 3 mm for summer tires and 4 mm for winter tires is often recommended by experts for better performance and grip.
Winter tires are mandatory in Germany under "wintery road conditions," which include black ice, packed snow, slush, ice, or frost. This is a situational requirement, meaning you must have appropriate tires (marked with the Alpine symbol) when these conditions are present, regardless of the calendar month. This is a crucial aspect for the German driving theory test.
Incorrect tire pressure significantly impacts driving safety by reducing grip, increasing braking distances, and impairing vehicle handling, making the car less stable. For the German driving theory exam, you must know how to properly check tire pressure and understand its critical role in preventing accidents and ensuring the vehicle's roadworthiness.
The 'Alpine symbol' (a snowflake within a three-peak mountain) on a tire indicates that it meets specific performance standards for severe snow conditions. In Germany, this symbol is crucial because, as of a certain date, new winter tires must carry this marking to fulfill the situational winter tire requirement. Older M+S tires without this symbol may have limited validity.
You are generally not allowed to mix different construction types of tires (e.g., radial and diagonal tires) on the same axle in Germany. While it is technically permissible to have summer tires on one axle and winter tires on the other, it is strongly advised against due to significant safety compromises in handling and stability. For optimal safety, use uniform tire types across all four wheels.
