OEM wheel and tire fitment specs for the 2014 Ford F-350, including bolt pattern (PCD), center bore diameter, thread size, rim diameter, rim width, wheel offset, and backspacing.
2014 Ford F-350 Fitment Specs
Baseline mounting dimensions used for interchange decisions.
A normal wheel spacer does not change bolt pattern. Hub rings cannot enlarge a wheel bore that is smaller than the hub. Brake clearance and tire package fitment still require vehicle-specific checks when not confirmed in the dataset.

Known OEM Fitment For 2014 Ford F-350
Below are the wheel and tire details currently confirmed for the 2014 Ford F-350. Values not shown as known can vary by trim, axle rating, brake package, and whether the truck is SRW or DRW. Do not guess these. Always verify against your driver door jamb tire placard, the owner’s manual, Ford service information, and by using the on-page calculator.
Bolt pattern (studs x PCD)
8x170

M14 x 2.00
Rim diameter (in)
Unknown. Confirm on door placard or OEM sources.
Rim width (in)
Unknown. Confirm on door placard or OEM sources.
Wheel offset (ET, mm)
Unknown. Varies by wheel and SRW vs DRW. Confirm with OEM sources.
Backspacing (in)
Unknown. Derives from width and offset. Use the calculator.
Tire section width (mm)
Unknown. Confirm on door placard or OEM sources.
Tire aspect ratio (%)
Unknown. Confirm on door placard or OEM sources.
Tire rim diameter (R)
Unknown. Confirm on door placard or OEM sources.
Important notes:
SRW and DRW F-350 models use different wheels and offsets. Do not interchange without confirming all dimensions and load ratings.
8x170 is not interchangeable with 8x6.5 inch (165.1 mm) or 8x180. The bolt circle must match exactly.
Center bore must be at least 124.9 mm. For hub-centric fit, the wheel bore should be 124.9 mm. Larger bores can be used if the wheel manufacturer approves lug-centric mounting for your use case.
How To Use The Wheel Interchange Calculator
The calculator on this page lets you compare a donor wheel and tire setup to your 2014 Ford F-350. It shows inner clearance to suspension and outer poke at the fender, and recalculates tire diameter when you change rim size.
Step 1. In Wheels from, select the donor vehicle or enter its custom wheel and tire specs.
Step 2. In Installed on, choose 2014 Ford F-350. If any OEM fields are unknown, enter the values from your door placard or owner’s manual.
Step 3. Custom wheel size lets you change rim diameter, rim width, and offset. Offset changes will move the wheel inward or outward. The tool will update backspacing automatically.
Step 4. Custom tire size lets you set section width and aspect ratio. When you change rim diameter, the tire diameter display updates so you can keep overall diameter close to stock.
Step 5. Review results. Watch inner clearance to struts, leafs, and sway bars, and outer poke relative to fenders and mud flaps. The tool visualizes these changes so you can avoid rubbing.
Step 6. Use the load index and speed rating from your door placard as your minimum. Never downrate tires on an F-350.
Fitment Checklist Before You Buy
Bolt pattern: 8x170 only.
Center bore: Wheel must have 124.9 mm or larger bore. For towing and heavy payloads, prefer wheels designed with a 124.9 mm hub bore for true hub-centric fit.
Lug seat and hardware: Confirm the wheel’s lug seat type and use matching lug nuts for M14 x 2.00 studs. Do not mix seat styles.
Load ratings: Wheel and tire load ratings must meet or exceed the OEM ratings from the door placard. This is critical for HD trucks.
SRW vs DRW: Do not cross-use without full spec verification. DRW wheels have unique offsets and widths.
Brake clearance: Ensure barrel and spoke design clear front calipers and rear drums or discs. Use the calculator and measure.
Offset and backspacing: Use the calculator to keep inner clearance safe while avoiding excessive poke that can cause rubbing or fender contact.
Tire diameter: Keep overall diameter close to stock for speedometer accuracy and gearing. Many aim for within about 3 percent, but always validate with the calculator and OEM guidance.
TPMS: Plan to transfer sensors or install compatible new sensors and perform the Ford relearn procedure.
Plus Sizing And Common Upgrades
Because OEM wheel sizes vary by trim and SRW vs DRW, confirm your baseline first. Then use these principles with the calculator.
Plus sizing concept: As rim diameter increases, choose a tire with a lower aspect ratio so overall diameter stays near stock. Use the calculator to verify total diameter and revs per mile.
Width and offset: If you increase wheel width, adjust offset so the inner edge stays clear of suspension and the outer edge does not protrude excessively. The calculator shows these movements.
Load and duty cycle: Any upsized tire must meet or exceed OEM load index. Off-road or towing packages may require even higher ratings. Follow the door placard minimums.
SRW off-road setups: Aggressive tread or wider tires can rub at full lock or under compression. Use the calculator and physically measure before buying.
DRW considerations: Dually rear spacing is critical. Only use dually-approved wheels and tire sizes intended for dual fitment, and verify clearance between duals under load.
Installation Tips
Test fit each wheel on the hub to confirm bore engagement and brake clearance before mounting tires.
Clean mating surfaces. Remove rust and debris from the hub face and wheel mounting pad to prevent runout and vibration.
Studs and nuts must be clean and dry. Do not lubricate threads unless Ford specifies it. Hand start all lug nuts to avoid cross-threading.
Tighten in a star pattern in multiple passes. Final torque must follow the OEM specification in your owner’s manual or service manual for M14 x 2.00 studs.
TPMS service: Install or transfer compatible sensors, use new seals as required, and perform the Ford TPMS relearn.
Re-torque after 50 to 100 miles and again after towing or heavy loads.

FAQs
What is the bolt pattern on a 2014 Ford F-350? 8x170. The bolt circle must match exactly. 8x6.5 inch and 8x180 will not fit.
What offset do I need? The OEM offset varies by wheel option and by SRW vs DRW. Check your door placard or OEM documentation, then use the calculator to match inner clearance and fender position when changing wheel width.
Will F-250 or other Super Duty wheels fit my F-350? Some Ford trucks also use 8x170, but offset, width, hub bore, and load ratings can differ. Always compare specifications with the calculator and verify hub bore 124.9 mm and adequate load capacity before assuming compatibility.
Do I need hub-centric rings? If the wheel bore is larger than 124.9 mm, consult the wheel manufacturer. For heavy duty trucks, a wheel designed with the correct 124.9 mm bore is preferred. If rings are used, they must be suitable for the vehicle’s load and heat, and approved by the wheel maker.
What tire size should I run? Tire sizes vary by trim and package. Use the size on your door placard as the baseline. When changing wheels, use the calculator to keep overall diameter close to stock and choose a tire with load index and speed rating that meet or exceed the placard.
Can I use spacers or adapters? Only if they are hub-centric, high quality, and properly sized for 8x170 and 124.9 mm hub, and only where legal and approved by your wheel manufacturer. Spacers change effective offset, so confirm inner and outer clearance with the calculator. Re-torque frequently.
What torque should I use on the lug nuts? Follow the OEM torque specification in the 2014 Ford F-350 owner’s manual or service manual for M14 x 2.00 studs. Do not guess. Tighten in a star pattern and re-torque after driving.
How do I keep my speedometer accurate with larger wheels? Use the calculator to compare overall tire diameter to stock. Keep diameter close to stock or have the vehicle recalibrated using appropriate service tools if you change it significantly.
