2018 Ford F-150 Wheel Interchange

2018 Ford F-150 Wheel Fitment and Interchange Guide

Known OEM Fitment For 2018 Ford F-150

The following specifications are the known OEM fitment data provided for the 2018 Ford F-150. Equipment can vary by trim, package, drivetrain, and wheel option, so confirm the specifications for your specific truck before purchasing wheels or tires.

These values should not be treated as a complete list of every 2018 F-150 wheel or tire option. Confirm the original equipment size on the driver-side door label, the owner’s manual, or the wheel and tire markings. The replacement wheel must also clear the brake components and suspension on your exact vehicle.

How To Use The Wheel Interchange Calculator

Use the calculator to compare wheels from a donor vehicle with the wheels installed on your 2018 Ford F-150. Enter the donor vehicle information in “Wheels from” and enter your truck in “Installed on.” Compare bolt pattern, center bore, wheel width, diameter, offset, backspacing, and tire dimensions before treating a donor wheel as a possible match.

• Use “Custom wheel size” to enter a wheel diameter, width, and offset when the exact wheel is not listed.
• Use “Custom tire size” to enter section width and aspect ratio for a proposed tire.
• When you change the rim diameter, review the updated tire diameter in the comparison. A different rim diameter normally requires a different tire size to maintain a suitable overall diameter.
• Compare the calculated inner and outer position changes, but remember that a calculator cannot verify brake clearance, hub contact, lug-seat design, load rating, or physical body clearance.
• Use the calculator as a screening tool, then confirm the final wheel and tire combination on the vehicle before driving.

Fitment Checklist Before You Buy

• Confirm the wheel uses the 6x135 bolt pattern.
• Confirm the center bore is compatible with the truck’s 87.1 mm hub. A smaller bore will not fit over the hub. A larger bore may require correctly sized hub-centric rings where appropriate.
• Check that the wheel’s lug holes, seat style, and included or required lug nuts match the wheel. Do not assume the original lug nuts are suitable for an aftermarket wheel.
• Compare diameter, width, offset, and backspacing with the known 17 x 7.5-inch, ET44 reference data, while allowing for trim and package differences.
• Verify the wheel and tire load ratings are suitable for the truck and its intended payload or towing use.
• Check brake caliper, suspension, steering, and inner-fender clearance with the vehicle at normal ride height and through steering movement.
• Confirm that the tire’s overall diameter, speed rating, load index, and construction are appropriate for the vehicle.
• Verify the tire does not rub at full steering lock, full suspension compression, or with the truck loaded.
• Inspect used wheels for cracks, bends, corrosion around the bead seat, damaged lug holes, and previous repairs.

Plus Sizing And Common Upgrades

Plus sizing means using a larger wheel diameter with a lower-profile tire while keeping the overall tire diameter reasonably close to the original setup. The correct plus-size combination for a specific 2018 Ford F-150 trim is not established by the supplied data, so do not assume that any larger wheel or wider tire will fit.

Enter the proposed wheel diameter, width, and offset in the calculator, then enter the proposed tire section width and aspect ratio. Review the calculated diameter and wheel-position changes. A wider wheel or a more outward offset can increase fender clearance risk, while a more inward position can reduce suspension or brake clearance.

Any upgrade should preserve adequate load capacity and maintain safe clearance. Speedometer, odometer, traction-control, and anti-lock braking behavior can be affected when overall tire diameter changes significantly. Confirm the final tire size with a tire professional and verify the vehicle manufacturer’s requirements.

Installation Tips

• Clean the hub face and wheel mounting surface before installation. Rust, dirt, or paint buildup can prevent the wheel from seating correctly.
• Install wheels with the correct lug nuts and seat type. The supplied lug hardware may not be interchangeable with OEM hardware.
• Thread lug nuts by hand first to avoid cross-threading the M14 x 1.5 wheel studs.
• Tighten the lug nuts in a star or crisscross pattern, then torque them to the vehicle or wheel manufacturer’s specified value. The exact torque value is not provided here and must be confirmed from an OEM or wheel manufacturer source.
• After installation, rotate the steering from lock to lock and inspect for contact. If possible, check clearance under suspension compression as well.
• Recheck lug torque after the first short drive and again according to the wheel manufacturer’s instructions.
• Check tire pressure using the pressure listed on the vehicle’s door label, unless a qualified tire professional or vehicle manufacturer specifies otherwise.

Tools And Helpful Supplies

A properly rated jack and jack stands are essential for safe wheel service. Never rely on a jack alone to support the truck. A torque wrench, compatible socket, wheel chocks, and a tire-pressure gauge are also useful for a careful installation.

• Automotive torque wrench for tightening lug nuts to the specified value.
• Automotive wheel chocks to help prevent vehicle movement during lifting.
• Use jack stands rated for the vehicle and place them only at approved support points.
• Keep a tire-pressure gauge and a suitable socket for the selected lug nuts available after installation.

FAQs

What is the bolt pattern for the 2018 Ford F-150?

The known bolt pattern provided for the 2018 Ford F-150 is 6x135. Confirm the pattern and exact wheel specification for your trim before buying.

What is the center bore of the 2018 Ford F-150?

The known center bore is 87.1 mm. A wheel with a smaller center bore will not fit over the hub. A larger-bore wheel may need appropriate hub-centric rings, depending on the wheel and application.

What lug thread size is listed for this truck?

The known thread size is M14 x 1.5. Lug nut seat style and overall lug nut dimensions still need to match the wheel, so verify the hardware before installation.

Can any 6x135 wheel fit a 2018 Ford F-150?

No. The bolt pattern is only one part of fitment. Center bore, offset, backspacing, wheel width, brake clearance, lug-seat design, load rating, and tire clearance must also be checked.

What is the known OEM wheel size?

The supplied reference data lists a 17-inch diameter, 7.5-inch width wheel with ET44 offset and 5.48-inch backspacing. Wheel equipment can vary, so confirm the size on the truck and compare any replacement using the calculator.

Can I install wider tires?

A wider tire may be possible, but the correct size cannot be determined from the supplied information alone. Enter the proposed tire and wheel dimensions in the calculator, then check load rating, inner clearance, fender clearance, steering clearance, and rubbing under compression.

Does changing wheel diameter change tire diameter?

Yes. Changing the rim diameter requires reviewing the complete tire size. The calculator updates tire diameter when the rim diameter changes, helping you compare the proposed setup with the installed setup.

Where should I confirm the final specifications?

Check the driver-side door label, owner’s manual, original wheel markings, tire sidewall, and the wheel manufacturer’s application data. If the vehicle has aftermarket suspension, spacers, different brakes, or other modifications, have a qualified technician verify the complete combination before driving.
