2021 Ford F-150 Wheel Interchange

2021 Ford F-150 Wheel Fitment and Interchange Guide

Known OEM Fitment For 2021 Ford F-150

The specifications below are the known OEM reference values supplied for the 2021 Ford F-150. Fitment can vary by trim, package, brake configuration, and factory wheel option, so confirm the exact vehicle and wheel before purchasing.

Based on the supplied tire dimensions, the reference tire format is 245/70R17. This page does not establish that every 2021 Ford F-150 trim uses this exact wheel and tire combination. Check the driver-side door-jamb tire label, owner's manual, original wheel markings, or a Ford dealer using the vehicle identification number.

How To Use The Wheel Interchange Calculator

Use the calculator to compare wheels from a donor vehicle with wheels installed on your 2021 Ford F-150. Enter or select the donor wheel specifications, then enter the known specifications for the truck in the installed-on-vehicle fields.

Review bolt pattern, center bore, rim width, diameter, and offset together. A wheel with the correct bolt pattern may still have unsuitable hub fitment, brake clearance, or fender clearance. The calculator is a comparison aid and does not replace a physical test fit or OEM confirmation.

You can also select a custom wheel size and adjust rim diameter, rim width, and offset. Enter a custom tire section width and aspect ratio when evaluating a tire change. Changing rim diameter updates the tire diameter shown in the comparison, which helps identify changes in overall diameter and sidewall height.

Before ordering, save the calculator results and compare them with the wheel manufacturer's specifications. Confirm that the listed load rating, lug-seat design, brake clearance, and tire size are appropriate for your specific truck.

Fitment Checklist Before You Buy

Start with the truck's exact trim and factory equipment. The supplied data may be partial, and different configurations can use different wheel, tire, brake, or suspension equipment.

• Confirm the 6x135 bolt pattern and verify that the wheel has six correct mounting holes.
• Check the wheel center bore against the 87.1 mm hub specification. A smaller bore will not fit over the hub. A larger bore may require correctly sized hub-centric rings if the wheel manufacturer permits them.
• Confirm that the wheel is rated for the truck's axle loads. Do not rely on appearance or diameter alone.
• Compare diameter, width, offset, and backspacing with the calculator and the physical wheel specifications.
• Verify inner clearance to the brake caliper, suspension, steering components, and hub before driving.
• Check outer clearance to the fender, liner, and suspension through the full steering range and suspension travel.
• Confirm the tire's load index, speed rating, overall diameter, and approved rim-width range. These values are not provided here and must be verified from the tire manufacturer and vehicle placard.
• Match the lug nuts to the wheel's seat type and confirm the required thread size is M14 x 1.5. Lug-seat style and final torque must come from the wheel and vehicle documentation.
• Confirm TPMS sensor compatibility and whether the sensors need programming after installation.

Plus Sizing And Common Upgrades

Plus sizing changes the wheel diameter while maintaining a tire diameter that is close to the original. It can alter sidewall height, ride comfort, steering response, speedometer accuracy, wheel weight, and clearance. No specific larger wheel or tire size is confirmed by the supplied information.

Use the custom wheel and tire fields to compare a proposed setup with the supplied 17 inch reference. Watch the calculated tire diameter, width, offset, and backspacing. A wider tire or a lower offset can move the tire outward, while a higher offset can move the wheel inward. Either change can create clearance problems.

Common upgrades may include a different wheel finish, a replacement wheel with the same basic dimensions, or a custom wheel and tire package. Each option still requires verification of load rating, brake clearance, hub fitment, lug hardware, TPMS compatibility, and tire approval. Do not assume that a wheel from another Ford truck or SUV fits solely because it uses a similar bolt pattern.

Installation Tips

Inspect the hub face and wheel mounting surface. Remove rust, dirt, paint buildup, and debris that could prevent the wheel from sitting flat. Never use excessive force to install a wheel with an undersized center bore.

Install only compatible lug nuts with the correct seat style and thread. Start every lug nut by hand to avoid cross-threading. Tighten in a star pattern, then use a calibrated torque wrench to apply the vehicle or wheel manufacturer's specified torque.

After installation, check for contact between the wheel, tire, brake components, suspension, and body. Turn the steering from lock to lock where safe, and inspect clearance with the vehicle at normal ride height. Recheck lug torque after the first short drive and follow the wheel manufacturer's recheck instructions.

Set tire pressure according to the vehicle's door-jamb label unless the tire or wheel manufacturer provides a documented alternative for the approved setup. If vibration occurs, stop and inspect wheel seating, balance, hub fitment, and lug hardware before continuing to drive.

Tools And Helpful Supplies

A torque wrench, socket set, jack and approved jack stands, wheel chocks, a tire pressure gauge, and a tread or clearance inspection tool can help with a careful installation. Use lifting points and support procedures specified in the owner's manual. A jack alone is not a safe substitute for jack stands when working beside or under a vehicle.

• Automotive digital torque wrench for controlled lug tightening.
• Digital tire pressure gauge for checking pressure after installation.

Use the vehicle owner's manual, the wheel manufacturer's installation guide, and the tire manufacturer's data as the controlling sources for lifting, torque, tire pressure, load rating, and approved fitment details.

FAQs

What is the bolt pattern for the 2021 Ford F-150?
The supplied OEM reference is 6x135. Confirm the exact vehicle and wheel application before ordering because the information provided may not cover every trim or factory configuration.

What is the center bore for the 2021 Ford F-150?
The supplied center bore is 87.1 mm. A wheel bore smaller than the hub will not install. A larger bore may require properly sized hub-centric rings when approved by the wheel manufacturer.

What lug thread size is listed for this truck?
The supplied thread size is M14 x 1.5. The correct lug nut seat style and final torque are separate requirements that must match the wheel and vehicle documentation.

What is the known OEM wheel size?
The supplied reference wheel is 17 inches in diameter and 7.5 inches wide, with ET44 offset and 5.48 inches of backspacing. This should be treated as a known reference, not proof that every 2021 Ford F-150 trim uses the same wheel.

What tire size corresponds to the supplied tire measurements?
The supplied measurements correspond to 245/70R17: 245 mm section width, a 70 percent aspect ratio, and a 17 inch rim diameter. Verify the factory-approved tire size and load requirements on the door label and in the owner's manual.

Can I use the calculator to compare a larger wheel?
Yes. Enter the proposed wheel diameter, width, and offset in the custom wheel fields, then enter the proposed tire section width and aspect ratio. The calculator updates tire diameter when rim diameter changes, but you must still verify physical clearance, load rating, brake clearance, and tire approval.

Does a matching 6x135 pattern guarantee fitment?
No. Bolt pattern is only one part of fitment. Center bore, wheel load rating, offset, backspacing, brake clearance, lug-seat design, tire size, and TPMS compatibility must also be checked.

Where can I confirm the correct factory specifications?
Check the driver-side door-jamb label, owner's manual, original wheel markings, tire and wheel manufacturer documentation, or a Ford dealer using the vehicle identification number. Use those sources to resolve any difference between a trim-specific specification and the reference data on this page.
