What size socket for lug nuts on 2002 Lexus IS300?
The lug nuts on a 2002 Lexus IS300 require a 19mm (3/4-inch) socket to fit the hex head. The wheel studs are 12mm in diameter with a 1.5mm thread pitch, and the lug nuts are sized to match that hex.
In practice, factory IS300 wheels are designed to be torqued to about 76 ft-lbs (103 Nm). If you’re using aftermarket wheels or lug nuts, always confirm the exact socket size and torque specification with the wheel manufacturer or service manual, as variations can occur.
Socket size and lug nut basics
Before you start, here are the core specifications to guide your tool choice and installation approach.
- Hex socket size: 19 mm (3/4 inch)
- Wheel stud size: 12 mm diameter with 1.5 mm thread pitch
- Recommended torque for lug nuts: ~76 ft-lbs (103 Nm) for stock wheels
Using the correct socket size and applying the proper torque helps prevent rounding the lug nuts or stressing the wheel studs during removal and installation.
Steps to remove and install lug nuts
Follow these steps to safely remove and reinstall wheels on a 2002 IS300 using the correct tools.
- Chock the vehicle and engage the parking brake; ensure you are on a level surface
- Loosen the lug nuts slightly with the wheel still on the ground using a 19 mm socket
- Raise the car with a jack until the wheel clearances allow removal
- Remove lug nuts and the wheel; inspect studs for corrosion or damage
- Install the wheel and hand-tighten the lug nuts in a criss-cross/star pattern
- Torque the lug nuts to about 76 ft-lbs (103 Nm) in the same star-pattern sequence
- Lower the vehicle and perform a final torque check on all lug nuts
Adhering to these steps ensures proper wheel seating and helps prevent rotor or stud damage over time.
Aftermarket wheels and lug nut considerations
Some aftermarket wheels may use different lug nut seat types or require alternative torque specifications. Always verify specific requirements with the wheel manufacturer and use the correct socket size and torque for your exact setup. When in doubt, consult a professional.
Summary
For a 2002 Lexus IS300, a 19 mm socket is the standard choice for lug nuts.
