How much tread must tires have to be considered safe?

In Germany, for tires to be considered safe for use, they must have a minimum tread depth of 1.6 millimeters. This requirement is essential because adequate tread depth is crucial for maintaining traction, especially in wet conditions. Tread patterns channel water away from the tire and help to prevent hydroplaning, enabling a vehicle to maintain control on slippery surfaces.

Having a tread depth below this standard increases the risk of reduced grip, longer stopping distances, and an overall decrease in vehicle safety. Therefore, the regulation reflects the need for sufficient tire performance to ensure safe driving conditions on the road. Choosing a tire with 1.6 millimeters of tread depth signifies compliance with safety standards and promotes effective handling and braking, which are vital for safe vehicle operation.
