The 2016 Ford Trucks Flex stands apart from the typical crossover with its long roofline, upright shape, and wagon-like presence, blending family-hauler practicality with a distinctly modern take on classic full-size proportions. Tire choice matters on this model because fitment changes by sub-model and wheel package, with four primary radial sizes used across the lineup: 235/60R17, 235/60R18, 235/55R19, and 255/45R20. The largest 20-inch fitment also opens the door to more visual and performance-oriented choices, including blackwall, redline, and raised white letter styling. The right decision starts with confirming the exact trim and wheel diameter already on the vehicle.
Which Tire Size Is Right for The 2016 Ford Trucks Flex
The 2016 Ford Trucks Flex uses four primary tire sizes, and the correct one depends on the specific sub-model and wheel package. Every fitment here is a radial, but rim diameter changes from 17 to 20 inches, so the first step is confirming the exact trim level and the actual wheel diameter on the vehicle before comparing tire choices.
A 235/55R19 tire uses a 235-millimeter section width, a 55-series aspect ratio, radial construction, and a 19-inch rim diameter. On the 2016 Ford Trucks Flex, this size is one of the primary modern radial fitments and is tied to a specific wheel setup rather than the full model range. Tire selection in this size starts with preserving the intended wheel diameter and overall fitment character of the vehicle. It is a useful choice when the Flex is already equipped with 19-inch wheels and you want to stay with that original wheel-and-tire format.
A 255/45R20 tire has a wider 255-millimeter section width, a 45-series profile, radial construction, and mounts on a 20-inch rim. This size appears on certain 2016 Ford Trucks Flex configurations and brings the most visible product variety, including BFGoodrich, Nitto, and Pro-Trac offerings, along with blackwall, redline, and raised white letter sidewall choices. Series options include g-Force Comp 2 AS, g-Force Sport Comp 2, Nitto NT555 G2, and Street Pro III. It is the size to evaluate carefully if appearance, brand preference, or a more assertive 20-inch wheel package is part of the goal.
A 235/60R17 tire combines a 235-millimeter section width with a 60-series profile, radial construction, and a 17-inch rim diameter. On the 2016 Ford Trucks Flex, this size serves a specific sub-model application and should be treated as a trim-dependent fitment rather than a universal one across the lineup. Its meaning is straightforward by modern standards, but the practical importance is wheel diameter confirmation before anything else. This is the size to stay with when the vehicle is equipped with the original-style 17-inch wheel setup and there is no plan to change wheel diameter.
A 235/60R18 tire keeps the same 235-millimeter section width and 60-series profile as the 17-inch version but is built for an 18-inch rim. For the 2016 Ford Trucks Flex, it is a separate primary fitment tied to certain trim and wheel combinations, so it should not be selected simply because the section width looks familiar. The difference in rim diameter is the key buying point, since that determines proper mounting and overall fitment. It makes sense when the Flex is already running 18-inch wheels and the goal is to maintain the correct size family for that setup.
Tire fitment on the 2016 Ford Trucks Flex varies by sub-model, and some trims use more than one wheel-and-tire package. Checking the exact trim matters because the lineup spans 17-, 18-, 19-, and 20-inch rim diameters, which changes the correct tire size immediately.

2016 Ford Trucks Flex Limited
The 2016 Ford Trucks Flex Limited uses either a 235/55R19 radial or a 255/45R20 radial, depending on the wheel package on the vehicle. Tire selection starts with confirming whether the Flex has 19-inch or 20-inch wheels, then narrowing the choice by brand, sidewall style, and tire series where applicable.
The 2016 Ford Trucks Flex SE uses a 235/60R17 radial fitment, making its tire decision more straightforward than the trims with multiple wheel packages. The focus here is staying with the proper 17-inch size and verifying that the current wheels have not been changed from the original-style setup.
The 2016 Ford Trucks Flex SEL uses either a 235/60R18 radial or a 255/45R20 radial, so the actual wheel diameter on the vehicle needs to be confirmed before choosing a tire. That distinction affects not only the correct size but also the available product character and sidewall styling choices, especially in the 20-inch fitment.
The tire sizes listed on this page assume factory-standard vehicle configuration. The following modifications may affect tire fitment and are not reflected in this guide:
Suspension changes (lowering, lift kits, spring replacements)
Body alterations (fender modifications, custom bodywork)
If your vehicle has been modified from factory specifications, verify tire clearance before purchase.

The most common questions for the 2016 Ford Trucks Flex come down to identifying the correct tire size by trim and wheel diameter, then comparing 20-inch product choices, sidewall styles, and practical fitment checks before road use.
Tire Size & Fitment
What tire size fits a 2016 Ford Trucks Flex?
The 2016 Ford Trucks Flex uses four primary tire sizes: 235/60R17, 235/60R18, 235/55R19, and 255/45R20. All of them are radial sizes, and the correct one depends on the specific sub-model and wheel package rather than the model name alone.
The most important step is matching the tire to the wheel diameter already on the vehicle. A Flex SE uses a different size than a Limited or SEL in some configurations, and trims with optional wheel packages can overlap, so checking the trim badge and the tire sidewall together is the safest way to narrow the fitment.
What size rim does a 2016 Ford Trucks Flex use?
A 2016 Ford Trucks Flex can use 17-, 18-, 19-, or 20-inch rims, depending on the sub-model and wheel package. Those rim diameters correspond to the four primary tire sizes used on this vehicle, so the wheel diameter is a central part of the fitment decision.
Rim diameter should be confirmed before comparing tread designs or sidewall styles because a 17-inch tire cannot mount on an 18-, 19-, or 20-inch wheel. Looking at the existing tire size on the sidewall is usually the quickest check, and it also helps reveal whether the Flex may have been fitted with a different wheel package over time.
Why does the 2016 Ford Trucks Flex have more than one tire size?
The 2016 Ford Trucks Flex has more than one tire size because tire fitment changes across the SE, SEL, and Limited trims, and some trims were equipped with more than one wheel-and-tire package. That is why the overall fitment range spans from 235/60R17 up to 255/45R20.
This means the right tire cannot be chosen by year and model alone. Identifying the exact trim and confirming the actual wheel diameter on the vehicle prevents ordering a tire that matches the wrong package, especially on SEL and Limited models where more than one primary size may be encountered.
Choosing the Right Tire
What should I consider when choosing a 255/45R20 tire for a 2016 Ford Trucks Flex?
Choosing a 255/45R20 tire for a 2016 Ford Trucks Flex starts with confirming that the vehicle is actually equipped with the 20-inch wheel package. In this size, available options vary by brand, tire series, sidewall treatment, rim-width specification, load information where stated, and other product-level details.
Once the size is confirmed, the real choice becomes how you want the Flex to present and what kind of tire character you prefer. Some owners may want a plain blackwall look, while others may prefer redline or raised white letter styling, so comparing the product details in the correct size is more useful than looking at the model name alone.
What sidewall styles are available for 2016 Ford Trucks Flex tires?
Sidewall style choices appear in the 255/45R20 fitment for the 2016 Ford Trucks Flex. Available treatments include blackwall, redline, and raised white letter, giving this size more visual variety than a basic replacement-only tire selection.
That matters most if the Flex already has the 20-inch wheel package and appearance is part of the buying decision. Sidewall styling does not change the need to match the correct size and rim diameter, but it can noticeably alter the vehicle’s overall look, especially on a model with broad slab sides and prominent wheel openings.
What brands offer tires for the 2016 Ford Trucks Flex?
The 255/45R20 size for the 2016 Ford Trucks Flex is available from BFGoodrich, Nitto, and Pro-Trac. Those products include several distinct tire series, so the brand choice is tied to the specific 20-inch fitment rather than to every tire size used on the Flex lineup.
Brand comparison makes the most sense after the correct size is confirmed, because the available product mix is size-specific. Looking at sidewall style, tire series, rim-width compatibility, and any stated load details will tell you more than the brand name alone when narrowing the right tire for the vehicle’s current wheel setup.
Restoration & Appearance
Which tire should I choose for a period-style 2016 Ford Trucks Flex?
A period-style approach for a 2016 Ford Trucks Flex usually means staying with the tire size and wheel diameter that match the trim and package already on the vehicle. Since this is a modern radial-fitment vehicle, the most relevant appearance decision tends to be sidewall presentation within the correct size rather than changing construction type.
The 255/45R20 fitment offers the broadest visual choice, including blackwall, redline, and raised white letter styles. Matching the tire to the existing wheel package preserves the Flex’s proportions, while checking period photos, original sales material, or marque-specific references can help if a very exact restoration-style presentation is the goal.
How does tire construction affect the appearance of a restored 2016 Ford Trucks Flex?
Tire construction is straightforward on a 2016 Ford Trucks Flex because the primary fitments are all radial. Appearance changes on this vehicle come more from size, wheel diameter, and sidewall treatment than from choosing between bias-ply and radial construction, since bias-ply is not part of the primary fitment picture here.
That makes the visual decision more about preserving the intended stance and wheel-to-tire proportion of the trim you own. A blackwall 20-inch tire gives a different presentation than a redline or raised white letter version, so staying with the correct size first and then selecting the sidewall style is the cleaner way to approach a restoration-minded result.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2016 Ford Trucks Flex?
Modifications can absolutely affect tire fitment on a 2016 Ford Trucks Flex. Aftermarket wheels, suspension changes, lowering, altered offsets, or body modifications can change the clearance picture enough that the original trim-based tire size may no longer tell the whole story.
A Flex that has been changed from stock should be checked at the wheel, not just by model name. Verifying wheel diameter, wheel width, tire clearance at full steering lock, and fender or suspension space helps prevent rubbing or mounting problems, especially when moving between the vehicle’s 17-, 18-, 19-, and 20-inch fitment families.
What should I inspect before driving a 2016 Ford Trucks Flex on new tires?
Before driving a 2016 Ford Trucks Flex on new tires, inspect the wheels for damage, confirm the tire size matches the wheel diameter, and check that inflation is set correctly for the vehicle’s use. It is also smart to look over the valve stems, lug torque, and general mounting condition after installation.
A short follow-up inspection is worthwhile once the vehicle has been driven and the tires have settled in. Watching for air loss, vibration, uneven contact, or any sign of rubbing at full turn can catch a fitment issue early, particularly on Flex models with larger wheel packages or vehicles that may have had wheel changes in the past.
How often should tires on a 2016 Ford Trucks Flex be inspected?
Tires on a 2016 Ford Trucks Flex should be inspected regularly, not just when tread looks worn. Pressure, tread wear pattern, cuts, sidewall damage, punctures, and irregular wear are all worth checking because this vehicle’s different wheel packages can mask developing issues until they become more noticeable on the road.
A quick visual check every time the vehicle is washed or fueled is a practical habit, with a more thorough inspection at regular service intervals. Looking across all four tires for matching wear is especially useful on a Flex, since the proper size is tied closely to wheel diameter and trim-specific setup rather than a one-size-fits-all fitment.
