Understanding Torque Measurements
- Torque is measured in pound-feet (lb-ft) or Newton meters (Nm).
- It is important to use the correct torque unit specified for your vehicle.
- Using a torque wrench is the most accurate way to achieve the recommended torque.

- Locate the wheel nut wrench and torque wrench.
- Loosen the wheel nuts using the wheel nut wrench in a diagonal pattern.
- Tighten the wheel nuts by hand until they are snug.
- Using the torque wrench, set it to the recommended torque value for your wheel size.
- Attach the torque wrench to each wheel nut and gradually tighten them in a star pattern.
- Continue tightening until the torque wrench clicks, indicating the desired torque has been reached.
- Repeat the process for all the remaining wheel nuts.
- Double-check the torque settings for each wheel nut to ensure accuracy.
Additional Tips and Precautions
- Always refer to the owner’s manual or consult a professional if you are unsure about the torque settings for your specific Hyundai i40 model.
- Do not use an impact wrench to tighten wheel nuts, as it may lead to over-tightening.
- Regularly inspect your wheel nuts for any signs of damage or wear, and replace them if necessary.
- After driving approximately 50 miles, recheck the wheel nut torque to ensure they are still properly tightened.
