What is the bolt pattern on a Ford 350?
Most Ford F-350 Super Duty trucks use an 8-lug wheel pattern on a 170 mm bolt circle (commonly written as 8x170). This is the standard for the majority of modern F-350 SRW and DRW configurations, though there are exceptions by era or variant. Always verify the exact spec for your vehicle before purchasing wheels.
Bolt-pattern basics
Understanding bolt patterns helps ensure you get wheels that fit properly. Here are the core elements you should know when evaluating an 8x170 setup for a Ford F-350.
- The pattern is defined by two numbers: the number of lug holes and the bolt-circle diameter (the circle passing through the centers of all lug holes).
- For most Ford F-350 Super Duty trucks, that pattern is 8 lugs on a 170 mm circle (8x170).
- In inches, that’s usually described as 8 on a 6.69-inch circle (approximately 6.69" bolt-circle diameter).
- This pattern is used on both front and rear wheels for SRW and DRW configurations on the F-350 Super Duty.
Bottom line: 8x170 is the standard for Ford F-350 Super Duty in recent decades, but confirm your exact model-year and configuration to be certain.
Ford F-350 Super Duty specifics
These notes cover the typical pattern and how it has been applied across the common F-350 configurations since the late 1990s.
- Typical model coverage: Ford F-350 Super Duty (1999 to present) uses 8x170 bolt pattern for both SRW and DRW variants.
- Versus other Ford 350 variants or non-Super Duty models, some older offerings or commercial lines may have used different lug patterns; verify from factory specs or a wheel retailer.
- Wheel compatibility reminders: a correct lug pattern is essential, but you must also check center bore size and offset to ensure proper fitment.
- When replacing wheels, specify the 8x170 pattern and the appropriate center bore and offset for your specific F-350 configuration.
Takeaways: For most Ford F-350 Super Duty trucks built since 1999, expect an 8x170 bolt pattern. If in doubt, measure or consult the owner’s manual or a dealership.
How to verify your exact pattern
Use these steps to confirm the bolt pattern on your particular F-350, because there can be variations by year, trim, or market region.
- Check the owner's manual, door jamb placard, or the wheel-spec sticker for the vehicle’s wheel details.
- Count the lug holes and measure the distance between opposing lug holes to determine the bolt-circle diameter.
- Use a bolt-pattern gauge or a template to confirm whether the pattern is 8x170.
- Ensure the wheel’s center bore matches your hub (Ford F-350 typically uses a hub bore around 106 mm, but verify for your exact year).
Once you’ve confirmed the pattern, you can select compatible wheels, lug nuts, and any needed adapters for your specific configuration.
Other Ford 350 variants
Note that not every 350-series vehicle uses the same wheel pattern. The classic F-350 Super Duty pickup and its current SRW/DRW variants generally adhere to the 8x170 standard, but Ford’s other 350-series vehicles (such as certain vans or commercial lines) may use different lug patterns depending on generation and market. Always verify the exact specification for your vehicle before purchasing wheels.
Summary
In the vast majority of modern Ford F-350 Super Duty trucks, the wheel bolt pattern is 8x170, applicable to both front and rear wheels in SRW and DRW configurations. To avoid mistakes, verify the exact year, model, and configuration against the owner’s manual or by checking with Ford or a trusted wheel retailer. When ordering wheels or adapters, confirm not only the lug pattern but also center bore and offset to ensure a correct fit.
What lug pattern is a Ford F350?
The F-350 lug pattern depends on the model year, with common patterns being 8x170mm for 1999–2023 models and 8x200mm for 2005 and newer Super Duty models. Earlier models, such as 1992–1997 F-350s, have an 8x6.5" (or 8x165.1mm) bolt pattern.
By model year
- 1999–2007: 8x170mm bolt pattern
- 2005–2023: 8x200mm bolt pattern
- 1992–1997: 8x6.5" (8x165.1mm) bolt pattern
- Pre-1992: 8x6.5" (8x165.1mm) bolt pattern
Important considerations
- Dual rear wheel (dually) vs. single rear wheel: Some models have different lug patterns for single rear wheel and dually configurations.
- Measurement: The bolt pattern is described by the number of bolts and the diameter of the bolt circle, or "pitch circle diameter" (PCD). For example, "8x170mm" means there are 8 bolts arranged in a circle with a diameter of 170 millimeters.
- Wheel swaps: You cannot directly swap wheels between models with different lug patterns without adapters.
What is the bolt pattern on a 2004 Ford F350?
The 2004 Ford F-350 lug pattern is 8x170mm. This means it has 8 lug holes and a bolt circle diameter of 170 millimeters.
- Bolt Pattern: 8x170mm.
- Explanation: The "8" indicates there are 8 lug holes, and the "170" indicates the bolt circle diameter in millimeters.
- Note: This applies to both the single-rear-wheel (SRW) and dual-rear-wheel (DRW) models for that year.
