What is the bolt pattern on a Toyota T100?
The Toyota T100 uses a six-lug wheel pattern: 6x139.7 mm (6 on 5.5 inches).
Pattern details
Before you shop for wheels or rotors, here are the essential facts about the T100’s bolt circle.
- Bolt pattern: 6x139.7 mm (6 on 5.5 inches)
- Center bore: commonly 106.1 mm (4.18 inches); hub-centric rings may be needed if the wheel bore differs
- Lug nut size and seat: typically M12x1.5 with a 60-degree conical (acorn) seat on most models from this era
These specifications help determine wheel compatibility, brake rotor fitment, and whether hub-centric rings are required for aftermarket wheels.
Compatibility notes
Cross-compatibility exists with other Toyota trucks and SUVs that use the same 6x139.7 mm bolt circle, but always verify both the lug pattern and center bore for your exact year and market. Some aftermarket wheels may advertise the correct pattern but differ in hub bore size or seating type.
Summary
In brief, the Toyota T100 uses a 6x139.7 mm bolt circle (6 lug on 5.5 inches). The center bore is commonly around 106.1 mm, though you should confirm for your specific vehicle to ensure proper fitment and, if necessary, hub-centric rings or adapters. This pattern aligns with many 1990s Toyota trucks, offering a wide range of wheel options for restoration or customization.
