Where are you not allowed to use retread tyres on 100 km/h buses?

In Germany, retreaded tyres are subject to specific regulations regarding their use on buses that are capable of speeds of up to 100 km/h. According to the German Road Traffic Regulations (StVZO), retread tyres are prohibited on the front axle of these buses due to safety concerns. The front axle bears more weight and experiences greater steering and braking forces, making it crucial that the tyres provide optimal performance and safety.

While retread tyres may be permitted on the rear axle under certain conditions, their use on the front axle is strictly restricted to ensure the safety of the vehicle and its passengers. Therefore, it is important to recognize the combination of options related to the specific axles to fully comply with the regulations. Understanding these rules helps in maintaining road safety and adhering to legal requirements for bus operation.
