You note that the tyres on your vehicle's front axle are showing uneven amounts of wear. What should be checked?

The selected combination of answers is correct because each aspect addresses a potential cause of uneven tyre wear, which is crucial for vehicle safety and compliance with German traffic regulations.

1. Chassis settings: Misalignment can cause uneven wear on tyres and significantly affect vehicle handling. Regular checks ensure the vehicle's wheels are aligned properly, as required by traffic safety standards.

2. Tyre inflation pressure: Incorrect tyre pressure can lead to accelerated wear, impacting fuel efficiency and safety. German regulations emphasize maintaining proper tyre pressure to ensure safe driving conditions.

3. Shock absorbers: Worn shocks can lead to poor road contact, which affects tyre wear and overall vehicle stability. It's vital to ensure that shock absorbers are in good condition for safe vehicle operation, as outlined in safety inspections mandated by German law.

Thus, addressing all three aspects is essential for maintaining vehicle safety and adherence to traffic regulations in Germany.
