What is the bolt pattern on a 2003 Lexus?
Most 2003 Lexus models use a 5x114.3 mm bolt pattern (five lug nuts on a 114.3 mm circle). Some of the larger SUVs in the lineup use a different, 6x139.7 mm pattern.
Overview of bolt patterns in the 2003 Lexus lineup
In brief, the majority of Lexus passenger cars from that year used the common 5-lug, 114.3 mm circle. The following models are representative of that standard.

- GS 430 (GS430)
- LS 430 (LS430)
- RX 300 (RX300)

Conclusion for this list: Most 2003 Lexus passenger cars use 5x114.3 mm bolt pattern; refer to the specific model if you’re fitting aftermarket wheels.
Exceptions: six-lug bolt pattern on larger Lexus SUVs
Two full-size SUVs in the 2003 Lexus family used a larger six-lug bolt pattern (139.7 mm circle), common among Toyota/Lexus trucks of that era.
- LX 470 (LX470)
- GX 470 (GX470)
Conclusion for this list: If you’re dealing with one of the LX or GX SUVs, expect a 6x139.7 mm bolt pattern rather than the 5x114.3 mm standard used by most other Lexus models of the time.
How to verify the bolt pattern on your specific vehicle
Always confirm with official documentation or a direct measurement. Look for wheel specification stickers on the driver’s door jamb or in the owner’s manual. You can also measure the bolt circle diameter with a ruler or caliper by measuring from the center of one lug hole to the center of the opposite lug hole. For absolute certainty, consult a dealer or a qualified shop with your VIN to confirm the exact lug pattern and hub bore.
Summary
In 2003, the vast majority of Lexus passenger cars used a 5x114.3 mm bolt pattern, making wheel compatibility straightforward for most wheels. The LX 470 and GX 470 SUVs used a 6x139.7 mm pattern, which requires different wheel specifications. Always verify for your exact model and year to avoid fitment issues.
