2017 Ford Flex Wheel Interchange

2017 Ford Flex Wheel Fitment Guide

Use this guide and the on-page wheel interchange calculator to compare wheel and tire dimensions for a 2017 Ford Flex. The specifications below are the known values supplied for this page. Fitment can vary by trim, package, replacement wheel, and tire selection, so confirm final dimensions with the vehicle owner’s manual, Ford service information, the wheel manufacturer, and a physical clearance check before driving.

Known OEM Fitment For 2017 Ford Flex

The following specifications are available for the 2017 Ford Flex fitment data on this page:

There is an apparent discrepancy in the supplied data: the rim diameter is listed as 18 inches, while the tire rim diameter value is listed as R19. Do not assume which value applies to your specific vehicle. Check the tire sidewall, the driver-door information label, the owner’s manual, or Ford service documentation. The calculator can help compare dimensions, but it does not replace the vehicle’s OEM fitment information.

How To Use The Wheel Interchange Calculator

Use the calculator to compare a donor wheel and tire setup with the setup installed on your 2017 Ford Flex. Enter the donor vehicle or donor wheel measurements under “Wheels from” and enter the Flex measurements under “Installed on.”

• Start with the known wheel diameter, width, and offset. If a value is unknown, verify it from the wheel casting, manufacturer documentation, or a qualified wheel supplier rather than guessing.
• Enter tire section width and aspect ratio for both setups when those values are known.
• Use the custom wheel size fields to test different rim diameters, widths, and offsets.
• Use the custom tire size fields to compare section width and aspect ratio changes.
• Review the calculator’s diameter and clearance comparison. Changing rim diameter also changes the tire diameter shown in the comparison.
• Compare the calculated result with the OEM specifications and inspect the vehicle in person before purchasing or installing parts.

A calculator can identify dimensional differences, but it cannot confirm every real-world clearance issue. Brake calipers, suspension components, wheel spoke shape, tire construction, fender clearance, and load rating must also be checked.

Fitment Checklist Before You Buy

• Confirm the 5x114.3 bolt pattern and verify that the wheel has the correct number and spacing of mounting holes.
• Confirm the wheel’s center bore. A wheel bore smaller than 63.4 mm will not fit over the hub. A larger bore may require properly specified hub-centric rings if the wheel manufacturer permits their use.
• Confirm the wheel offset and width. A different offset can move the wheel toward the suspension or outward toward the fender.
• Check the wheel’s load rating against the vehicle’s requirements. The supplied data does not include a load-rating value, so obtain it from Ford or the wheel manufacturer.
• Verify the tire’s load index, speed rating, overall diameter, and approved rim-width range.
• Confirm whether the vehicle uses tire-pressure monitoring sensors and whether the replacement wheels are compatible with them.
• Check that the lug hardware matches the replacement wheel’s seat type, thread size, and required engagement. The supplied thread size is M12 x 1.5, but the correct lug nut seat and style still need confirmation.
• Ask the wheel supplier for written confirmation when a wheel is advertised as compatible but does not list the required offset, center bore, load rating, or brake clearance.

Plus Sizing And Common Upgrades

Plus sizing generally uses a larger rim diameter with a lower-aspect-ratio tire to maintain a similar overall tire diameter. It can change steering response, ride comfort, road-noise levels, wheel protection, speedometer accuracy, and the risk of damage from potholes.

Do not select a replacement tire from section width alone. The tire must fit the wheel’s approved width range and maintain appropriate load and speed ratings. Use the calculator to compare the original and proposed tire diameters, but verify the final tire size with a tire professional and the vehicle manufacturer’s information.

Because the supplied data includes both an 18-inch rim value and an R19 tire rim value, confirm the actual installed configuration before considering a plus-size change. The correct baseline may vary by trim or equipment package, and no additional compatible sizes are provided here.

Installation Tips

• Inspect the hub face, wheel mounting surface, studs, lug nuts, and wheel for corrosion, cracks, damaged threads, or other defects.
• Clean rust and debris from the hub and wheel mounting surfaces without removing material that could affect fitment.
• Install the correct lug hardware by hand first. Do not force a mismatched lug nut onto the studs.
• Tighten lug nuts in a star or crisscross pattern, then use the vehicle manufacturer’s specified torque. The correct torque value is not provided here, so obtain it from Ford service information or the owner’s manual.
• After installation, rotate the wheel by hand and check clearance to the brake caliper, strut, control arms, steering components, and inner wheel well.
• Check fender and liner clearance with the steering turned fully left and right. If suspension compression clearance is uncertain, have a qualified technician inspect it.
• Set tire pressure according to the vehicle’s tire-information label, not the maximum pressure molded into the tire sidewall.
• Recheck lug torque after the first short drive and again according to the wheel manufacturer’s instructions.
• Reset or relearn the tire-pressure monitoring system when required by the vehicle or sensor manufacturer.

Tools And Helpful Supplies

Useful equipment includes a torque wrench, correctly sized socket, breaker bar, jack and approved jack stands, wheel chocks, a tire-pressure gauge, and a tread or clearance inspection tool. Choose lifting equipment rated for the vehicle and use it only on approved lift points. Never work under a vehicle supported only by a jack.

FAQs

What is the bolt pattern for the 2017 Ford Flex?
The known bolt pattern supplied for this page is 5x114.3. Confirm the wheel manufacturer’s specifications before purchase.

What is the center bore for the 2017 Ford Flex?
The known center bore value is 63.4 mm. A smaller wheel bore will not fit over the vehicle hub, while a larger bore may require suitable hub-centric rings if approved by the wheel manufacturer.

What wheel offset is listed for the 2017 Ford Flex?
The supplied wheel offset is ET39, or 39 mm. Offset is only one part of fitment, so compare it with wheel width, spoke clearance, tire size, and the calculator results.

Does the supplied data confirm an 18-inch or 19-inch setup?
No. The data lists an 18-inch rim diameter and also lists the tire rim diameter as R19. This conflict must be confirmed using the tire sidewall, door label, owner’s manual, or OEM service information before selecting replacement wheels or tires.

Can I use any 5x114.3 wheel on a 2017 Ford Flex?
No. Matching the bolt pattern alone is not enough. You must also confirm center bore, offset, width, brake and suspension clearance, wheel load rating, lug hardware, and tire compatibility.

How does changing wheel diameter affect the calculator comparison?
Changing the custom rim diameter updates the tire diameter in the comparison. The tire’s actual section width and aspect ratio still need to be entered correctly, and the result must be checked against OEM requirements and physical clearance.

What lug thread size is listed?
The supplied thread size is M12 x 1.5. Confirm the lug nut seat style and required engagement for the specific replacement wheel before installation.

Can I rely on the calculator to approve a wheel swap?
No. The calculator is a comparison aid. Final approval requires confirmation of OEM specifications, wheel load rating, tire ratings, brake clearance, suspension clearance, fender clearance, and correct mounting hardware.
