What is the bolt pattern on a 1999 Toyota Tercel?
The bolt pattern on a 1999 Toyota Tercel is 4x100, meaning four lug holes arranged on a 100 millimeter circle.
Understanding bolt patterns helps ensure wheels and adapters fit correctly. For the 1999 Tercel—part of Toyota’s late-1990s compact lineup—the wheel hub layout typically follows a 4-lug, 100 mm pitch circle, a common configuration among similar Toyotas of the era. Details beyond the bolt count, such as center bore and lug-nut size, can affect fitment, so verifying each specification for your vehicle is wise.
Bolt pattern specifics
Below are the core specifications commonly associated with the 1999 Tercel's wheel hub layout.
- Number of bolts: 4
- Bolt circle diameter (PCD): 100 mm (4x100)
- Center bore: typically about 54.1 mm for many Toyota passenger cars of this era (verify on your vehicle)
- Lug nut size and seat: commonly M12x1.5 with a 60-degree conical seat (verify for your exact wheel specification)
In practical terms, these numbers determine which wheels can be mounted and whether adapters or spacers are required. When in doubt, check the hub-centric requirements and consult a tire/wheel professional.
Note on wheel compatibility
While 4x100 is the standard for many 1990s Toyotas, some aftermarket wheels or adapters may have different center bore or seat requirements. Always confirm the exact specifications for your car before purchasing wheels or adapters.
How to confirm on your own car
To confirm the bolt pattern for your exact vehicle, use these steps:
- Check the owner's manual or the door jamb/trunk sticker for wheel specs (bolt pattern, center bore, lug nut size).
- Inspect the hub or rotor face for stamped markings indicating the PCD (e.g., "PCD 100" or "4x100") and center bore size.
- Measure the bolt pattern with a ruler/caliper by measuring the distance between opposite lug holes and dividing by two to obtain the PCD in millimeters.
- Measure the wheel center bore diameter; if a wheel's center bore is larger than the hub, you may need a hub-centric spacer or ring to ensure proper fitment.
- Consult a professional wheel shop or reference Toyota's parts catalog using your VIN to confirm exact specs for your car.
Conclusion: Your 1999 Tercel uses a 4x100 bolt pattern, but always verify center bore and lug-nut details for your wheels. This helps avoid fitment issues when upgrading or replacing wheels.
Summary
The 1999 Toyota Tercel uses a standard 4-lug, 100 mm bolt pattern (4x100) that typically pairs with a ~54.1 mm center bore and M12x1.5 lug nuts with a 60-degree conical seat. Always verify exact details for your vehicle by consulting the owner's manual, hub stamping, or a wheel professional to ensure proper fitment and safety.
