What is the bolt pattern on a Lexus IS350?
The Lexus IS350 uses a five-lug bolt pattern on a 114.3 mm bolt circle (commonly written as 5x114.3 or 5 on 4.5 inches).
In practical terms, this means most wheels configured for Lexus and Toyota platforms that use the 5x114.3 pattern will fit the IS350, provided other fitment factors like hub bore, offset, and brake caliper clearance are also correct. The standard center bore is 60.1 mm, and lug nuts are typically M12x1.5 with a 60-degree conical seat.
Bolt pattern specifications
Key measurements you should verify when shopping for wheels or adapters are listed below.
- Bolt pattern: 5x114.3 mm (5 on 4.5 inches).
- Center bore: 60.1 mm.
- Lug nut size (thread): typically M12x1.5.
- Lug nut seat: 60-degree conical (tapered) seat.
Knowing these specs helps ensure wheels mount securely and sit properly against the hub, avoiding balance issues or caliper interference.
Compatibility notes and fitment tips
Before purchasing new wheels for an IS350, consider these practical points to avoid installation problems.
- All 5-lug IS350 models from roughly 2006 through the early 2010s share the 5x114.3 pattern; always confirm the exact year and trim before buying wheels.
- Aftermarket wheels in a different bolt pattern require adapters, which can affect clearance, offset, and suspension geometry; prefer wheels made for 5x114.3 unless you plan to use adapters.
- Check hub-centric compatibility and consider hub rings if the wheel’s center bore differs from 60.1 mm to reduce vibration and center the wheel properly.
In practice, sticking with wheels designed for a 5x114.3 pattern and matching the 60.1 mm center bore simplifies installation and helps maintain balanced performance.
Summary
Recap: The Lexus IS350 uses a 5-lug bolt pattern on a 114.3 mm bolt circle (5x114.3) with a 60.1 mm hub bore and standard lug nut sizing (M12x1.5, 60-degree seat). This pattern is shared across most IS models and many Toyota/Lexus wheels, though always verify year-specific details, hub compatibility, and offset for proper fitment.
