What is the torque spec for the lug nuts on a 2008 Lexus RX350?
The standard lug-nut torque for a 2008 Lexus RX350 is 80 ft-lbs (108 N·m). Tighten the nuts in a star pattern using a calibrated torque wrench and recheck after a short drive to ensure proper seating.
Understanding what this spec means
Torque specifies how much rotational force is applied to the lug nuts to clamp the wheel to the hub. Getting it right prevents wheel loosening or damage to studs and wheels. This value applies to factory wheels and OEM lug nuts; aftermarket hardware may have different requirements.
Official specification for the 2008 RX350
According to Lexus/Toyota service data commonly referenced for this model, lug nuts should be torqued to 80 ft-lbs (108 N·m). If you’re using aftermarket wheels or lug nuts, or a different wheel size, consult the wheel or vehicle manufacturer for the exact requirement.
To ensure safety and proper seating, follow these steps below:
- Use a calibrated torque wrench that reads in ft-lbs (and optionally in N·m for cross-checks).
- Inspect the wheel studs for damage or corrosion; replace if needed.
- With the wheel properly seated on the hub, hand-tighten the lug nuts in a star pattern to eliminate wobble.
- Torque the lug nuts to 80 ft-lbs (108 N·m) in the same star pattern, in small steps if your wrench allows.
- Re-check that all nuts are at the final torque before driving.
After installation, re-check the lug-nut torque after driving 50-100 miles (80-160 km) to allow seating and any minor tightening to settle.
Notes on aftermarket wheels
Wheels not installed by the original manufacturer may have different torque requirements. Always verify with the wheel manufacturer or consult the vehicle service manual for exact torque and seating pattern if using aftermarket components.
Summary
For a 2008 Lexus RX350, lug nuts typically require 80 ft-lbs (108 N·m) of torque, tightened in a star pattern and re-checked after initial driving. Using a quality torque wrench and following the steps above helps ensure wheel safety and proper seating.
