Tesla Model S Lug Nut Torque
Maintaining your Tesla Model S in optimal condition requires attention to detail, including proper wheel maintenance. One of the most crucial aspects is ensuring your lug nuts are tightened to the correct specifications. In this comprehensive guide, we will cover everything you need to know about Tesla Model S lug nut torque, from the recommended values to the step-by-step process of tightening them and putting your car into Jacking Mode.
Why Lug Nut Torque Matters
Lug nut torque refers to the specific amount of rotational force, measured in pound-feet (lb-ft) or Newton meters (Nm), required to tighten the lug nuts that secure your wheels to the car. Using the correct torque is essential for various reasons:
Safety: Properly torqued lug nuts ensure your wheels are securely attached, preventing them from loosening or detaching while driving, which could lead to serious accidents.
Wheel and Stud Integrity: Overtightening lug nuts can damage the wheel studs, lug nuts, and even the wheels themselves.
Brake Performance: Unevenly torqued lug nuts can lead to uneven wear on brake rotors and potential braking issues.
Tesla Model S Lug Nut Torque Specs
The correct lug nut torque for the Tesla Model S is 129 lb-ft (175 Nm) for all factory wheel sizes (19", 20", and 21"). This information can also be found in your Model S owner's manual.
Tools You'll Need
Torque wrench (capable of reaching 129 lb-ft or 175 Nm)
21mm socket
Jack and jack stands (or Tesla-approved jacking method)
How to Put Your Tesla Model S in Jacking Mode
Before you begin working on your wheels, it's essential to put your Tesla Model S in Jacking Mode. This mode raises the suspension to its highest position, providing more clearance and stability for jacking and working on the wheels. To activate Jacking Mode:
Go to Controls on your car's touchscreen.
Select Service.
Tap Jack Mode.
Confirm by tapping Yes.
The car will automatically raise to Jacking Mode. You will hear a chime when the process is complete.
How to Torque Lug Nuts on Your Tesla Model S
Prepare Your Vehicle: Park your Model S on a level surface and engage the parking brake.
Locate Jacking Points: Refer to your owner's manual for the specific jacking points on your Model S.
Place Jack Stands: Position the jack stands under the designated jacking points.
Jack Up the Car: Slowly raise the car with the jack until it's high enough for you to comfortably work on the wheels. Lower the car onto the jack stands for added safety.
Hand-Tighten Lug Nuts: Use a lug wrench to hand-tighten all the lug nuts in a star or criss-cross pattern to ensure even pressure.
Use the Torque Wrench: Set your torque wrench to 129 lb-ft (175 Nm).
Torque Each Lug Nut: In the same star or criss-cross pattern, tighten each lug nut until the torque wrench clicks, indicating the correct torque has been reached.
Lower Your Car: Carefully lower your Model S back to the ground using the jack.
Disengage Jacking Mode: Go back to the Service menu on your touchscreen and tap Jack Mode again to disengage it.
Recheck Torque: After driving for about 50-100 miles, recheck the lug nut torque to ensure they remain properly tightened.
Important Tips:
Always re-torque the lug nuts after driving approximately 50-100 miles to ensure they remain properly tightened.
If you don't have a torque wrench, have the lug nuts torqued at a reputable tire shop or Tesla service center.
Avoid overtightening the lug nuts, as it can damage the studs and wheels.
Properly torqued lug nuts are vital for the safety and performance of your Tesla Model S. By following this guide and using the correct torque specs, you can ensure a secure and enjoyable driving experience.
