2016 Ford Flex Wheel Interchange

2016 Ford Flex Wheel Fitment Guide

Known OEM Fitment For 2016 Ford Flex

The following specifications are the known OEM fitment values available for the 2016 Ford Flex. Fitment can vary by trim, package, wheel design, and brake configuration, so confirm the exact specification for your vehicle before purchasing wheels or tires.

Important: The supplied data lists an 18-inch rim diameter and a tire rim diameter of R19. A tire marked R19 is designed for a 19-inch wheel, not an 18-inch wheel. Treat this as a value that needs confirmation rather than assuming both specifications describe the same factory configuration. Check the tire sidewall, driver-door placard, owner’s manual, and VIN-specific OEM parts information.

How To Use The Wheel Interchange Calculator

Use the calculator to compare Wheels from (donor vehicle) with Installed on (your vehicle). Enter the donor wheel’s diameter, width, and offset, then enter the known or verified specifications for your 2016 Ford Flex.

• Start with the bolt pattern, center bore, wheel diameter, wheel width, and offset.
• Use the custom wheel size fields when the donor wheel does not match a standard vehicle entry.
• Enter the custom tire section width and aspect ratio when comparing tire sizes.
• Review the calculated changes in inner clearance, outer position, and overall tire diameter before buying.
• Changing the rim diameter updates the tire diameter in the comparison. Make sure the tire rim diameter matches the wheel diameter.

The calculator is a comparison aid, not a substitute for a physical test fit or OEM confirmation. It does not confirm brake clearance, suspension clearance, fender clearance, load rating, or legal requirements.

Fitment Checklist Before You Buy

• Confirm the vehicle’s exact trim and factory wheel package using the VIN, door placard, owner’s manual, or Ford parts information.
• Verify the 5x114.3 bolt pattern and confirm that the wheel has five correctly positioned mounting holes.
• Check that the wheel center bore is compatible with the 63.4 mm hub. A larger bore may require correctly sized hub-centric rings; a smaller bore will not fit over the hub.
• Confirm the M12 x 1.5 thread size and use lug nuts that match the wheel’s seat type and the vehicle’s specifications.
• Compare wheel width and offset with the calculator, then check clearance to the strut, suspension, brake components, and fender.
• Verify the wheel’s load rating and the tire’s load index and speed rating. These values are not provided here and must be confirmed from the wheel and tire manufacturer.
• Confirm that all four tires are approved for the selected wheel diameter and that the tire sidewall marking matches the wheel diameter.
• Do not rely on a compatible bolt pattern alone. A wheel can share the bolt pattern and still fail because of center-bore, offset, brake, load, or clearance issues.

Plus Sizing And Common Upgrades

Plus sizing generally means installing a larger-diameter wheel with a lower-aspect-ratio tire while maintaining a similar overall tire diameter. The goal is to preserve speedometer behavior and clearance while changing wheel appearance or handling characteristics.

For this 2016 Ford Flex, the supplied information includes both an 18-inch rim value and an R19 tire value. Because those values conflict, do not treat either one as a confirmed upgrade baseline until your current wheel and tire markings are checked.

When evaluating a larger wheel, use the calculator to compare the complete wheel and tire combination. Also consider ride comfort, pothole damage risk, tire cost, wheel load rating, steering feel, and available replacement tires. A larger wheel does not automatically provide better vehicle performance.

Installation Tips

• Inspect used wheels for cracks, bends, corrosion around the bead seat, and damaged lug holes before installation.
• Clean the vehicle hub and wheel mounting surface. Rust or debris can prevent the wheel from seating correctly.
• Install the correct lug nuts for the wheel’s seat design. Do not force incompatible conical, ball-seat, or shank-style hardware.
• Thread lug nuts by hand first to avoid cross-threading.
• Tighten the lug nuts in a crisscross pattern, then torque them to the vehicle or wheel manufacturer’s specified value. The correct torque value is not provided here, so confirm it in the owner’s manual or OEM service information.
• After installation, rotate the wheel by hand and check for contact with brake components, suspension parts, and the inner fender.
• Lower the vehicle fully, recheck torque using the specified procedure, and inspect tire pressure using the door-placard recommendation.
• Recheck lug torque after the initial driving period specified by the wheel or vehicle manufacturer.

Tools And Helpful Supplies

Useful equipment may include a properly rated floor jack, jack stands, wheel chocks, a torque wrench, a socket that fits the lug nuts, a tire-pressure gauge, and a hub or mounting-surface cleaning brush.

Examples of general-purpose supplies include a torque wrench and a digital tire pressure gauge. Select tools that are suitable for the vehicle and follow the manufacturer’s instructions. Never work under a vehicle supported only by a jack.

FAQs

What is the bolt pattern for the 2016 Ford Flex?
The known bolt pattern is 5x114.3. Confirm the exact vehicle and wheel application before purchase because bolt pattern alone does not establish complete fitment.

What is the center bore?
The known center bore is 63.4 mm. A wheel with a larger center bore may need properly sized hub-centric rings, while a wheel with a smaller bore will not fit over the vehicle hub.

What lug thread size is listed?
The listed thread size is M12 x 1.5. The lug nut seat type and final torque specification still need to be confirmed for the specific wheel and vehicle.

Can I use the listed R19 tire on an 18-inch wheel?
No. A tire marked R19 is designed for a 19-inch wheel. The supplied data also lists an 18-inch rim, so verify the actual tire and wheel markings before mounting anything.

Is a wheel with the correct 5x114.3 pattern guaranteed to fit?
No. Center bore, offset, width, backspacing, brake clearance, suspension clearance, fender clearance, wheel load rating, and lug hardware must also be checked.

What wheel size is listed for this vehicle?
The supplied OEM data lists an 18-inch diameter, 7.5-inch width, ET39 offset, and 5.29-inch backspacing. Because trim-specific variations may exist and the listed tire diameter conflicts with the wheel diameter, confirm the factory combination using the vehicle and OEM sources.

How can I compare a donor wheel with my Ford Flex?
Enter the donor wheel under “Wheels from (donor vehicle)” and the verified Ford Flex values under “Installed on (your vehicle).” Use the custom wheel and tire fields when necessary, then inspect the calculated diameter and clearance changes. A final physical clearance check is still required.

Where should I confirm the correct tire pressure and wheel specifications?
Check the driver-door placard, owner’s manual, VIN-specific Ford parts or service information, and the markings on the existing wheels and tires. If those sources disagree, consult a qualified tire or wheel professional before ordering parts.
