What bolt pattern is a Ford F250?
The Ford F-250 uses an 8-lug bolt pattern on a 170 mm diameter circle (8x170).
This configuration is standard on most Super Duty F-250 models from the late 1990s to today, covering both single-rear-wheel (SRW) and dual-rear-wheel (DRW) variants. This article explains what that means for wheels, how to verify the pattern on your truck, and what to consider when buying aftermarket wheels or replacements.
Understanding the 8x170 bolt pattern
Bolt pattern describes two things: how many lug studs the wheel uses (eight) and the diameter of the circle those studs form (170 millimeters). On the F-250, eight lugs are evenly spaced around a 170 mm circle, which translates to about 6.69 inches. This is distinct from the 5-lug pattern found on lighter-duty Ford trucks like the F-150 and from other common eight-lug patterns you might encounter.
Generational coverage and configurations
Ford’s Super Duty lineup, including the F-250, has generally maintained the 8x170 bolt pattern across modern generations. This means both SRW and DRW variants share the same lug count and circle diameter, though wheel width, offset, and hub concepts can vary by year and trim. Always verify the exact spec for your specific vehicle year and configuration.
Wheel compatibility checklist
In preparing to replace or upgrade wheels, owners should check several compatibility factors to ensure a proper fit. The list below outlines what to verify before purchasing wheels or adapters.
- Confirm eight lug holes on a 170 mm circle (8x170) is the wheel pattern you’re buying and that your vehicle uses the same pattern.
- Consider your vehicle’s configuration (SRW vs DRW) as it affects wheel width, offset requirements, and clearance, even though the bolt pattern remains 8x170.
- Verify the wheel’s center bore matches or is larger than the hub bore; use centering rings if needed to achieve proper centering.
- Check the offset and backspacing to avoid rubbing on suspension components or brakes and to ensure proper brake clearance.
- Consult the wheel manufacturer’s fitment guide or a dealer/tire shop to confirm year-specific compatibility with your F-250.
In practice, sticking to wheels designed for Ford F-250 Super Duty or explicitly listed as 8x170-fitment reduces the risk of fit issues, while professional installation can confirm precise alignment and torque specs.
Notes on potential variations
Although the 8x170 bolt pattern is standard for most modern F-250s, rare factory or regional specifications can vary. When in doubt, check the door placard on the driver’s side jamb or the owner’s manual for the exact bolt pattern for your specific truck.
Summary
The Ford F-250’s bolt pattern is an eight-lug arrangement on a 170 mm circle (8x170). This configuration is standard across most recent Super Duty models, including both SRW and DRW variants. Always verify the exact pattern, center bore, and offset for your year and configuration before buying wheels or rims, and consult a tire and wheel professional if you’re unsure.
