These are vehicle-year records whose recorded OEM ranges overlap this 2016 Ford Flex. Overlap is not a guarantee that a specific wheel will install. Selected-wheel comparison is in the calculator below.
Evaluated 26 donor years. Listed 24 eligible overlaps (not all evaluated years are compatible). Showing all listed.
Years grouped because recorded compatibility evidence is equivalent. Each year keeps its own page.
Approximate position vs the mid OEM package: outer change -3.18 mm, inner change -3.18 mm. This uses aggregated width/offset ranges, not a specific wheel.

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.
| Specification | Known value |
|---|---|
| Bolt pattern | 5x114.3 |
| Center bore | 63.4 mm |
| Thread size | M12 x 1.5 |
| Rim diameter | 18 inches |
| Rim width | 7.5 inches |
| Wheel offset | ET39 |
| Backspacing | 5.29 inches |
| Tire section width | 235 mm |
| Tire aspect ratio | 55% |
| Listed tire rim diameter | R19 |
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.
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.
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.
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.
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.
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.
Wheel interchange depends on more than bolt pattern. Where data is available, this site compares recorded OEM values:
A normal wheel spacer does not change bolt pattern. Hub rings cannot enlarge a wheel bore that is smaller than the hub. Brake clearance and tire package fitment still require vehicle-specific checks when not confirmed in the dataset.
