2021 Ford F-350 Wheel Interchange

2021 Ford F-350 Wheel Fitment Guide at wheelinterchange.com

Known OEM Fitment For 2021 Ford F-350

The items below reflect the fitment data provided for this specific model year. If a value is unknown or varies by trim such as SRW vs DRW, verify it on your door-jamb placard, the owner’s manual, or your Ford dealer, then confirm results with the on-page calculator.

Important: The 2021 F-350 is sold in Single Rear Wheel and Dual Rear Wheel configurations. DRW wheels and SRW wheels use different offsets and hardware. Do not mix SRW and DRW wheels without confirming full compatibility with Ford documentation and the calculator.

How To Use The Wheel Interchange Calculator

• Set Installed on to 2021 Ford F-350.
• If you are considering wheels from another vehicle, set Wheels from to that donor vehicle. If you are considering aftermarket sizes, use Custom wheel size and Custom tire size.
• Enter known OEM data for your truck first. If your OEM width or offset is unknown, read your wheel markings on the back of a stock wheel or get the values from Ford. Then enter them.
• Adjust Custom wheel size: rim diameter, rim width, and offset. The tool will show inner clearance and outer poke changes compared to your OEM wheel.
• Adjust Custom tire size: section width and aspect ratio. When you change rim diameter, the tire diameter shown in the comparison will update so you can track overall diameter and speedometer effect.
• Evaluate results. Watch inner clearance to suspension and brakes, outer poke relative to fenders and mudflaps, track width change, and speedometer difference. Aim for zero contact at full steering lock and full suspension compression.

Fitment Checklist Before You Buy

• Pattern and hub: 8x170 bolt pattern and 124.9 mm hub bore. Aftermarket wheels with a larger bore require 124.9 mm hub-centric rings.
• SRW vs DRW: Offsets and rear spacing differ. Buy wheels designed for your axle type only.
• Load rating: Wheel and tire load ratings must meet or exceed your truck’s GAWR. Heavy-duty tires and wheels are required for towing and payload.
• Offset and backspacing: Unknown from the data provided. Obtain your OEM offset, then use the calculator to compare. Keep adequate inner clearance to brake calipers, tie rod ends, leafs, and front wheel liners.
• Brake and caliper clearance: Physically test-fit a front wheel to ensure spoke and barrel clearance over the calipers and hub.
• Lug seat type: Match the lug nut seat to the wheel seat type. Do not mix acorn conical seats with mag or ball seats.
• Stud engagement: Minimum thread engagement should be at least the stud diameter. For M14 studs, aim for full nut thread engagement. Do not use spacers unless you can verify safe stud engagement and hubcentric support.
• TPMS: 2021 F-350 uses TPMS. Plan to transfer or install sensors and perform the TPMS relearn procedure after installation.
• Tire diameter: Use the calculator to keep overall diameter close to stock if you want to avoid recalibration. Larger tires may require leveling or lift and may affect towing performance.
• Spare compatibility: Ensure your spare will clear brakes and studs and that the lug nuts’ seat type matches if you rotate it in.

Plus Sizing And Common Upgrades

Because the exact OEM size and offset are not provided here and can vary by SRW vs DRW and option packages, confirm your stock wheel width, diameter, and offset from Ford first. Then:

• Plus-one or plus-two: Increase wheel diameter while selecting tire profiles that maintain overall tire diameter close to stock. The calculator will update tire diameter so you can track speedometer impact.
• Wider stance: Use the calculator to model a wider wheel and different offset. Verify that inner clearance remains safe and outer poke stays within your fenders or flares.
• Larger tires for off-road: Check for rubbing at full lock and full compression. You may need a leveling kit or trimming of inner liners. Towing loads and gearing may be affected by larger diameters.
• Dually specifics: DRW trucks often require wheels with unique offsets and rear dual spacing. Use wheels designed for DRW only and confirm tire pairing clearance between the duals.

Installation Tips

• Prep: Park on level ground, chock wheels, use a properly rated floor jack and jack stands. Loosen lug nuts slightly before lifting.
• Hub cleaning: Use a wire brush to remove rust and debris on the hub face and the center pilot. A clean hub reduces runout.
• Dry threads: Most OEMs specify clean, dry studs and nut seats. Do not lubricate studs or apply anti-seize to lug nut threads unless the manufacturer instructs it.
• Hub-centric fit: If your new wheel bore is larger than 124.9 mm, install correct hub-centric rings to center the wheel on the hub.
• Torque pattern: Hand start all nuts, then torque in a star pattern in stages to the Ford-specified torque for your 2021 F-350. Re-torque after 50 to 100 miles.
• TPMS: Install compatible sensors. Perform relearn according to Ford service information after the wheels and tires are mounted and set to placard pressure.
• Road test: Check for vibrations, rubbing at full lock, and brake clearance noises. Re-check torque and pressures after the test drive.

FAQs

• What is the bolt pattern for the 2021 Ford F-350?

  8x170 with a 124.9 mm center bore and M14 x 1.5 wheel studs.

• What are the OEM wheel width, diameter, and offset for my F-350?

  They are not provided here and can vary by SRW vs DRW and packages. Read the markings on a stock wheel, check your door placard, or ask a Ford dealer, then enter those values in the calculator.

• Can I use wheels from a different Ford truck on my 2021 F-350?

  Only if the bolt pattern, center bore, load rating, offset, and brake clearance are correct for your truck. Use the calculator to compare and physically test-fit. SRW and DRW wheels are typically not interchangeable.

• Will 8x6.5 wheels fit my 2021 F-350?

  No. 8x6.5 is a different bolt circle. The 2021 F-350 uses 8x170.

• Do I need hub-centric rings on this truck?

  If your aftermarket wheel has a larger center bore than 124.9 mm, use hub-centric rings sized to 124.9 mm to ensure proper centering and reduce vibration.

• What lug nuts should I use?

  Use M14 x 1.5 lug nuts with the seat type that matches your wheel. Seat type varies by wheel design. Do not mix seat types.

• What torque should I use on the lug nuts?

  Torque varies by model and hardware. Consult the 2021 Ford F-350 owner’s manual or service information for the correct specification, then torque in a star pattern and re-torque after 50 to 100 miles.

• How much can I change tire diameter without issues?

  Use the calculator to compare against stock. Small changes may be acceptable, but larger increases can affect speedometer accuracy, gearing, ABS calibration, and fender clearance. Confirm clearance at full lock and compression and consider speedometer recalibration if you go significantly larger.

• Will snow chains fit with larger wheels or tires?

  Chain clearance depends on inner clearance to suspension and body. Use the calculator to estimate inner clearance changes. Verify physically before driving with chains.
