Tyre maintenance — recommended rotation interval For most passenger vehicles under normal service, tyre rotation is generally performed at approximately:

Introduction / Context:
Tyre rotation equalizes wear among all wheel positions, improving tread life, traction, and noise characteristics. Service intervals vary by vehicle and tyre type, but recognizing a typical interval is valuable for maintenance planning.

Given Data / Assumptions:

• Passenger car on paved roads with normal load.
• Non-directional radial tyres (or rotation pattern permitted by manufacturer).
• No staggered fitment or asymmetric tread constraints.

Concept / Approach:
Many manufacturers recommend rotation around every 5000–8000 km. This interval balances practical service visits (e.g., oil change schedule) with benefits in even wear. Choosing 6000 km falls squarely within this common band and aligns with typical owner’s manual guidance.

Step-by-Step Solution:
Identify standard maintenance ranges: 5000–8000 km.Select the option nearest the middle of that range: 6000 km.Note that severe service (towing, aggressive alignment) may require shorter intervals.

Verification / Alternative check:
Inspection-based rotation can also be triggered by tread depth differentials between front and rear; many shops pair rotations with every second engine oil service in kilometer-based markets.

Why Other Options Are Wrong:
1000 km is too frequent and impractical. 4000 km may be acceptable but is earlier than common recommendations. 10000 km is sometimes used, but 6000 km better reflects typical median guidance.

Common Pitfalls:
Ignoring directional tyres (must stay on same side), and staggered sizes (front/rear swap not possible); forgetting to re-torque wheel nuts after rotation.

Final Answer:
6000 km
