What is the bolt pattern on a 2008 Toyota FJ Cruiser?
The bolt pattern is 6-lug on a 139.7 mm bolt circle (6x139.7 mm), commonly referred to as 6x5.5 inches, with a center bore of 106.1 mm.
In this article, we explain what those measurements mean, how they affect wheel compatibility, and what to check when replacing wheels or upgrading the setup.
Bolt pattern basics
Knowing the core measurements helps you compare wheels and adapters across different vehicles.
Key specifications you need to know about this bolt pattern:
- Lug count: 6
- Bolt circle diameter (BCD): 139.7 mm (5.5 inches)
- Center bore: 106.1 mm
These numbers define how the wheel mounts to the hub and whether it centers properly. If any of these differ, wheels may not mount correctly or align properly on the vehicle.
Model-year scope and compatibility
Most 2007–2014 FJ Cruiser models share this bolt pattern, which helps when sourcing wheels from aftermarket suppliers or used parts. Always verify with the wheel or adapter vendor to confirm exact specs for your exact vehicle.
Representative year range that uses this pattern:
- 2007–2014 Toyota FJ Cruiser
When buying wheels from other vehicles, confirm compatibility with the 6x139.7 mm pattern, the 106.1 mm center bore, and the correct offset to maintain proper fitment and braking clearance.
Practical fitting considerations
Wheel offset and clearance
Offset and backspacing determine how far a wheel sits in relation to the fender and brake components. Too much inward or outward offset can cause rubbing or steering issues, especially with wider aftermarket wheels.
Guidance for fitting wheels:
- Ensure the wheel offset/backspacing suits the FJ Cruiser’s suspension and brake setup to avoid rubbing on the fenders or calipers.
- Verify hub bore compatibility; use hub-centric rings if the wheel hub bore is larger or to improve centering.
- Check brake caliper clearance and spoke design, especially with larger or wider wheels.
- Confirm that the wheel’s lug pattern matches (6x139.7 mm) and that the studs and lug nuts are appropriate for the wheel.
With the right offset, hub-centered alignment, and caliper clearance, wheels that fit the 6x139.7 mm pattern can be installed safely and maintain proper performance.
Summary
The 2008 Toyota FJ Cruiser uses a 6x139.7 mm bolt pattern (6 lug, 139.7 mm bolt circle) with a center bore of 106.1 mm. This pattern is common among many Toyota trucks and SUVs of the era, giving a broad range of wheel options. Always verify exact specs—lug count, bolt circle diameter, center bore, and offset—before purchasing wheels or adapters to ensure proper fitment and safety.
