What is the bolt pattern on F350?
The Ford F-350 Super Duty generally uses an 8-lug wheel pattern on a 170 mm bolt circle (8x170). This is standard across most modern SRW and DRW configurations, but you should verify for your exact year and model to avoid fitment issues.
Overview of the bolt pattern
Wheel fitment for the F-350 is defined by three main numbers: the number of lug holes, the bolt circle diameter, and the center bore. For most contemporary F-350 Super Duty pickups, the configuration is eight lugs on a 170 mm circle, with a hub bore around 87.1 mm. These specs generally apply to both single-rear-wheel (SRW) and dual-rear-wheel (DRW) variants, though aftermarket wheels must still be matched to the hub diameter and thread size.
Current models and typical specs
Below is a concise summary of the key facts you’re most likely to encounter when shopping for wheels or tires for a modern F-350. This list aims to cover the common, widely used configuration across model years.
- Bolt pattern: 8x170 mm (8 on 170 mm bolt circle).
- Center bore: typically around 87.1 mm, with hub-centric rings used on some aftermarket wheels.
- Applicable to both SRW and DRW variants on most 1999–present Super Duty generations; always verify for your exact year and trim.
Knowing these basics helps you avoid mismatched wheels and ensures compatibility with any aftermarket gear you might consider.
How to verify your exact year and configuration
To be certain you’re ordering or mounting the correct wheels, confirm your specific truck’s specs before purchase. The steps below guide you through a precise check.
- Check the driver's door jamb sticker for wheel and tire specifications, including lug pattern and center bore notes.
- Consult the owner’s manual or the Ford official website for your exact model year’s wheel specs.
- Look up your VIN on Ford’s site or a trusted parts catalog to pull production details that may affect fitment.
- Measure or confirm the center bore and lug thread size if you’re considering aftermarket wheels to ensure proper hub fitment and lug engagement.
With these checks, you’ll reduce the risk of ordering wheels that don’t fit your F-350’s hub or lug configuration.
Common variations and caveats
While the 8x170 mm pattern covers most modern F-350 Super Duty trucks, a few caveats apply:
- Early generations or non-US markets may show variations; always verify against your exact year and build.
- Dual rear-wheel (DRW) configurations use the same 8x170 pattern but can require wider tires and wheels; confirm clearance for suspension components and fender arches.
- Some aftermarket wheels are hub-centric rather than lug-centric; ensure the center bore matches or use appropriate hub-centric rings.
In practice, the 8x170 mm bolt pattern is the standard you’ll encounter most often, but tying your purchase to the exact model year and configuration helps prevent fitment problems.
Conclusion
The Ford F-350 Super Duty typically uses an 8x170 mm bolt pattern with an approximate 87.1 mm center bore, applicable to most SRW and DRW configurations from modern generations. Always verify your specific year, trim, and wheel configuration using the door sticker, manual, VIN lookup, or a trusted parts catalog to ensure a perfect fit.
Summary
For most F-350 owners, expect 8 lug holes on a 170 mm bolt circle (8x170) with a center bore near 87.1 mm. Confirm the exact specs for your truck’s year and variant before buying wheels or tires, as small differences can affect fitment and safety.
