Most Ford Fiesta models use M12 x 1.5 lug nuts with a 60-degree conical seat and a 21 mm wrench size; however, there are exceptions depending on year, market, and wheel configuration. Always verify for your specific car.
The Fiesta has spanned several generations and regions. Some early European variants used wheel bolts instead of lug nuts, and wheel specifications can vary by trim and aftermarket wheels. To install or replace wheels safely, confirm the exact fastener size from the owner’s manual, door placard, or Ford's official specifications for your VIN.
Common specifications for modern Fiesta configurations
These specifications reflect typical setups found on recent Fiesta models and widely sold variants. If you are fitting aftermarket wheels or have a regional model, verify your exact specs.
- Thread size: M12 x 1.5 (the most common for Fiesta lug nuts)
- Seat type: 60-degree conical seat
- Hex size: 21 mm wrench for the lug nuts
- Wheel mounting: 4x108 mm bolt pattern (PCD)
- Fastener count: 4 lug nuts per wheel
- Note: Some early or regional Fiesta variants used wheel bolts instead of studs and lug nuts
In practice, the baseline is M12 x 1.5 with a 60° conical seat and a 21 mm lug wrench, on a 4x108 mm PCD wheel setup. Always confirm if you are unsure.
How to verify the exact size for your car
To confirm the lug size for your exact Fiesta, follow these steps.
- Check the owner's manual or Ford's official online spec database using your vehicle's year, region, and trim.
- Inspect the driver-side door pillar placard or the wheel info placard; it often lists wheel size, lug nut type, and torque.
- Look at the lug nuts themselves: measure the hex width with a caliper or lug-nut gauge and note the seat type.
- If you have aftermarket wheels, consult the wheel manufacturer or retailer for the correct lug sizing and seating.
- When in doubt, contact a Ford dealer or service center with your VIN for the exact specification.
Verifying in this way reduces the risk of cross-threading or wheel detachment and ensures proper torque during installation.
Torque and maintenance notes
Correct torque is essential for safety. Typical lug nut torque for a Ford Fiesta falls in the range of approximately 90–110 Nm (about 67–81 ft-lb), depending on year and wheel type. Always torque to the specification printed on the door placard or in the owner's manual, and recheck torque after the first 50–100 miles (80–160 km) of driving with new wheels or after rotating tires.
Summary
The exact wheel nut size on a Ford Fiesta varies by year, market, and wheel setup, but the most common configuration in recent models is M12 x 1.5 with a 60-degree conical seat, using a 21 mm lug wrench and a 4x108 mm bolt pattern. Verify with official documentation or a dealer for your specific vehicle, especially if you have aftermarket wheels or a regional variant. Correct fastener size, seat type, and torque safety are essential for safe wheel installation.
