Will 8X6.5 fit F350?
Short answer: In most cases, no. Ford F-350 Super Duty trucks use an 8x170 mm bolt pattern, while an 8x6.5 wheel uses a different bolt circle (8 on 6.5 inches), so they do not bolt up without modification. If you see adapters marketed for this swap, tread carefully: they can compromise safety, load rating, and warranty on a heavy-duty pickup.
Understanding bolt patterns and the F-350 specification
To understand why the fit is unlikely, it helps to know what the bolt pattern and related measurements mean. The bolt pattern (the number of lug holes and the circle they form) determines whether a wheel can bolt to the hub. The F-350 Super Duty commonly uses an 8-lug pattern on a 170 mm bolt circle, while 8x6.5 wheels are designed for a different circle pattern. Even when lug holes line up, other factors like center bore size, offset, and brake caliper clearance must also align. This is why simply swapping in an 8x6.5 wheel usually won’t work without additional modifications or considerations.
Key compatibility factors
Before attempting any wheel swap, here are the main elements that determine whether a wheel will fit:
- Bolt pattern match: 8x170 mm on the F-350 versus 8x165.1 mm (approximately 8x6.5") on many 8x6.5 wheels.
- Center bore compatibility: the hub bore must fit or hub-centric rings must be used to center the wheel properly.
- Offset and backspacing: incorrect offset can cause rubbing on suspension components, brakes, or the fenders, and can affect steering geometry.
- Brake caliper clearance: the wheel must clear the calipers at all steering angles and during compression.
- Load rating and certification: mismatched wheels can exceed the vehicle’s designed load rating or void warranties.
These factors collectively determine whether a wheel will seat properly and maintain safe operation on a Ford F-350. If any one of them is off, the wheel may not fit or could create safety risks.
What you can do if you want a similar look or function
There are safe, practical options if you’re aiming for an 8x6.5 appearance or vibe while staying with the correct F-350 compatibility:
- Choose wheels that are specifically manufactured for the 8x170 mm Ford Super Duty bolt pattern.
- Consult a reputable wheel and tire shop to confirm exact fitment, including offset, center bore, and brake clearance for your exact model and wheel width.
- If contemplating adapters, only use high-quality, vehicle-rated adapters installed by professionals; understand that they may affect load ratings, warranty, and may require modifications that are not recommended for heavy-duty use.
- Verify tire size compatibility with the wheel and the truck’s overall suspension and fender clearance to avoid rubbing or suspension contact.
These steps help ensure you preserve safety, reliability, and warranty while achieving your desired look or performance.
Summary
In summary, an 8x6.5 wheel does not naturally fit a Ford F-350 due to a mismatched bolt pattern (8x170 mm is common on F-350, vs. 8x6.5 on many other brands). For a proper and safe fit, select wheels designed for the F-350’s 8x170 bolt pattern, or work with a qualified shop to explore only safe, recommended options. Adapters exist but carry tradeoffs in safety, load capacity, and warranty, so they should be considered cautiously.
When did Ford switch from 8x6.5 to 8x170?
Ford switched from the 8x6.5 bolt pattern to the 8x170mm pattern for its F-250 and F-350 Super Duty trucks in 1999. All Ford trucks with the 8x170mm bolt pattern are from 1999 or newer, while the 8x6.5 pattern was used on earlier models, such as the 1998 and older F-250 and F-350 pickups.
- 1999: The change to the 8x170mm pattern was made starting with the 1999 model year Super Duty trucks (F-250 and F-350).
- Prior to 1999: Ford used the 8x6.5 bolt pattern on its F-250 and F-350 trucks.
- 1999 and newer: The 8x170mm bolt pattern has been the standard for these trucks since 1999.
