In most Lexus IS 200t models, the lug nuts use an M12 x 1.5 thread with a 60-degree conical seat, a standard 19 mm hex head, and a wheel bolt pattern of 5x114.3 mm. The factory tightening torque is roughly 103 Nm (76 ft-lb). Confirm exact specs with your year and wheel package in the owner's manual or service booklet.
Key specs at a glance
To help you identify the correct lug hardware or replacements, here are the core measurements and torque targets you’re likely to encounter on IS 200t models.
- M12 x 1.5 thread size
- 60-degree conical (tapered) seat
- Hex drive size typically 19 mm

Context and caveats
Market and year variations
While the IS 200t shares common hardware across many regions, some model years or markets may use slightly different lug nut lengths or seat styles depending on wheel designs. Always consult the vehicle’s documentation or confirm with a Lexus dealer for your exact VIN.
Aftermarket wheels and safety
Aftermarket wheels can require different lug nuts (e.g., ball seat or different thread pitch). Using incorrect lug nuts risks wheel loosening or damage. When in doubt, replace with the proper OEM or OEM-equivalent hardware recommended for your wheels and run a torque check after installation.
How to verify on your car
Ways to verify the lug nut specs include consulting the owner’s manual, inspecting the existing lug nuts, or contacting a dealer or qualified mechanic to read the service data for your specific vehicle configuration.
Summary
The usual lug nut specification for a Lexus IS 200t is M12 x 1.5 with a 60-degree conical seat, 19 mm hex, 5x114.3 mm bolt pattern, tightened to about 103 Nm (76 ft-lb). Always confirm against your exact model year and wheel setup, especially if aftermarket wheels or spacers are involved.
