What is the legally prescribed minimum tread depth across the main profile of all the tyres on your car?

The legally required minimum tread depth for all tyres on cars in Germany is 1.6 mm, measured across the main tread of the tyre. This rule ensures sufficient grip and safety, especially in wet or slippery conditions. Driving with tyres below this limit is illegal and increases the risk of accidents due to reduced traction. Always check your tread depth regularly and replace tyres before they reach this minimum to maintain road safety.
