The 2013 Ford Trucks Flex stands apart from many modern family haulers with its long roofline, squared-off silhouette, and wagon-like presence. It blends crossover practicality with a design that appeals to buyers who want something more distinctive than a typical three-row utility vehicle. Tire fitment on the 2013 Ford Trucks Flex depends on the exact sub-model and wheel package, with four primary radial sizes used across 17-inch, 18-inch, 19-inch, and 20-inch rims. The 20-inch fitment also opens the door to more style-oriented choices, including blackwall, raised white letter, and redline options. The key is matching the tire to the right trim and wheel before weighing appearance, road use, and overall presentation.
Which Tire Size Is Right for The 2013 Ford Trucks Flex
The 2013 Ford Trucks Flex uses four primary tire sizes, and the right one depends first on the exact sub-model and wheel diameter. These are all radial fitments, but they are spread across 17-inch, 18-inch, 19-inch, and 20-inch rims, so confirming the actual wheel on the vehicle matters before comparing tire choices or appearance options.
235/55R19 is a modern metric radial size in which 235 identifies the section width in millimeters, 55 is the aspect ratio, R means radial construction, and 19 is the rim diameter in inches. On the 2013 Ford Trucks Flex, this size suits a specific wheel setup rather than every trim level. It represents a contemporary, low-profile crossover fitment with a balance between ride height and handling response. This is the size to evaluate when the vehicle already carries 19-inch wheels and the goal is to stay with the proper modern sizing format.
255/45R20 is a modern metric radial size, with a 255-millimeter section width, a 45-series profile, radial construction, and a 20-inch rim diameter. For the 2013 Ford Trucks Flex, this fitment is tied to the larger wheel package and brings the broadest visible product variety. Available choices include BFGoodrich, Nitto, and Pro-Trac, along with blackwall, raised white letter, and redline sidewall treatments across several tire series. This size deserves extra attention if appearance matters as much as fitment, especially on a Flex built around 20-inch wheels.
235/60R17 is a modern metric radial size that uses a 235-millimeter section width, a 60-series aspect ratio, radial construction, and a 17-inch rim. On the 2013 Ford Trucks Flex, this size belongs to a specific sub-model and wheel combination, so it should not be treated as universal across the lineup. Its taller profile relative to the 20-inch setup reflects a different wheel-and-tire package rather than an interchangeable alternative. This is the size to pursue when the Flex is equipped with the 17-inch wheel specified for that trim.
235/60R18 is a modern metric radial size with a 235-millimeter section width, a 60-series profile, radial construction, and an 18-inch rim diameter. On the 2013 Ford Trucks Flex, it applies to a particular trim and wheel arrangement instead of the whole model range. The size keeps the same general width as the 17-inch version but pairs it with a different wheel diameter, which makes wheel confirmation essential before selection. It is the right starting point when the vehicle is already riding on the 18-inch setup used for that configuration.
Tire fitment on the 2013 Ford Trucks Flex varies by sub-model and, in some cases, by wheel package within the same trim. Checking the exact trim and confirming the wheel diameter on the vehicle will narrow the choice quickly and prevent mixing one Flex setup with another.

2013 Ford Trucks Flex Limited
The 2013 Ford Trucks Flex Limited uses either a 235/55R19 radial or a 255/45R20 radial, depending on its wheel setup. That makes wheel confirmation the first step, followed by choosing between a straightforward modern replacement or, on the 20-inch fitment, a more appearance-driven sidewall option.
The 2013 Ford Trucks Flex SE uses the 235/60R17 radial size, making its fitment more straightforward than the trims with multiple wheel packages. Tire selection centers on staying with the correct 17-inch size and verifying that the vehicle has not been changed to a different wheel diameter over time.
The 2013 Ford Trucks Flex SEL uses either 235/60R18 or 255/45R20 radial tires, so the trim alone is not enough to choose a tire. The actual wheel diameter needs to be confirmed first, especially since the 20-inch option also opens up more visible product and sidewall variation.
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.

Owners of a 2013 Ford Trucks Flex usually need to sort out trim-specific tire size, wheel diameter, and 20-inch product choices before anything else. These FAQs focus on fitment, construction, sidewall options, selection factors, and the checks worth making before regular road use.
Tire Size & Fitment
What tire size fits a 2013 Ford Trucks Flex?
The 2013 Ford Trucks Flex uses four primary tire sizes: 235/60R17, 235/60R18, 235/55R19, and 255/45R20. All are radial sizes, but they do not apply across the entire model range. The correct fitment depends on the exact sub-model and the wheel package installed on the vehicle.
The most important first step is checking the actual wheel diameter on the Flex rather than assuming every trim uses the same tire. SE uses 235/60R17, while Limited and SEL can use larger wheel packages. If the vehicle has been changed from its original wheels, use the mounted wheel size and overall setup as the basis for selection.
What size rim does a 2013 Ford Trucks Flex use?
A 2013 Ford Trucks Flex can use 17-inch, 18-inch, 19-inch, or 20-inch rims, depending on the trim and wheel package. Those rim diameters correspond to 235/60R17, 235/60R18, 235/55R19, and 255/45R20 tires. The tire size and rim diameter need to stay matched.
Rim diameter is the quickest way to narrow the fitment because the Flex was offered with several wheel-and-tire combinations. Reading the tire sidewall or checking the wheel itself usually confirms what is on the vehicle now. That matters even more if a previous owner changed wheels, since trim alone may not tell the whole story.
Why does the 2013 Ford Trucks Flex have more than one tire size?
The 2013 Ford Trucks Flex has more than one tire size because different sub-models and wheel packages use different rim diameters. SE uses 235/60R17, SEL uses either 235/60R18 or 255/45R20, and Limited uses either 235/55R19 or 255/45R20. Each size belongs to a specific wheel setup.
That means the right choice is not simply the most common Flex size or the largest one available. Tire selection starts with identifying the trim and confirming whether the vehicle has 17-, 18-, 19-, or 20-inch wheels. Once that is settled, the next decision becomes product style, brand, and sidewall treatment within the correct size.
Choosing the Right Tire
What should I consider when choosing a tire for a 2013 Ford Trucks Flex?
Start with the correct tire size for the exact 2013 Ford Trucks Flex sub-model and wheel diameter. This vehicle uses several radial sizes, so a 17-inch SE setup should not be approached the same way as a 20-inch SEL or Limited setup. The right size comes before any brand or style decision.
After confirming size, compare the details that affect how the Flex will look and be used, such as sidewall treatment, tire series, rim-width compatibility, and load specification where stated. The 255/45R20 fitment offers the most visible product variation, so that setup invites more comparison than the smaller-wheel configurations.
What sidewall styles are available for 2013 Ford Trucks Flex tires?
Sidewall style variation appears in the 255/45R20 fitment for the 2013 Ford Trucks Flex. Available choices include blackwall, raised white letter, and redline. Those options give the 20-inch setup a wider visual range than a typical modern crossover replacement tire.
Sidewall treatment does not change the need to match the correct 20-inch tire size and overall wheel setup. It does, however, change the personality of the vehicle, especially on a Flex with more custom or enthusiast-oriented styling. Buyers who want a cleaner factory-like look usually lean blackwall, while RWL or redline create a more distinctive presentation.
What brands offer tires for the 2013 Ford Trucks Flex?
For the 255/45R20 fitment used on certain 2013 Ford Trucks Flex models, available brands include BFGoodrich, Nitto, and Pro-Trac. Those products span several radial tire series rather than a single uniform option. That gives the larger-wheel Flex owner more than one direction to consider.
Brand should be compared alongside size, sidewall style, and wheel compatibility rather than treated as the only decision. BFGoodrich appears in more than one series, Nitto offers a performance-oriented modern radial choice, and Pro-Trac adds visual sidewall variety. The better match depends on how the Flex is being presented and driven.
Restoration & Appearance
Which tire should I choose for a period-style 2013 Ford Trucks Flex?
A period-style approach on a 2013 Ford Trucks Flex usually means starting with the correct original sizing format for the trim and wheel package already on the vehicle. Since all primary fitments are modern radial sizes, the look comes more from wheel choice and sidewall treatment than from switching to an older construction type.
The 255/45R20 fitment offers the widest appearance spread because it is available in blackwall, raised white letter, and redline versions. That makes it the most useful setup for shaping the vehicle’s visual character. Buyers aiming for a more restrained presentation often stay with blackwall, while more expressive builds may favor RWL or redline.
How does tire construction affect the appearance of a restored 2013 Ford Trucks Flex?
On the 2013 Ford Trucks Flex, construction is less of an appearance divider than it is on older collector vehicles because the primary fitments are all radial. The visual differences here come mainly from tire size, wheel diameter, and sidewall treatment rather than from choosing between bias-ply and radial designs.
That shifts the appearance decision toward proportion and presentation. A Flex on 17-inch or 18-inch wheels carries a different stance than one on 19s or 20s, and the 20-inch fitment adds blackwall, raised white letter, and redline choices. Matching those details to the vehicle’s intended look will matter more than construction changes on this model.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2013 Ford Trucks Flex?
Yes, modifications can affect tire fitment on a 2013 Ford Trucks Flex. Aftermarket wheels, suspension changes, ride-height adjustments, and body modifications can all change how much room the vehicle has for a given tire size. That matters especially on trims that use the larger 19-inch or 20-inch wheel packages.
A Flex that no longer carries its original wheel setup should be checked for actual rim diameter and width before replacement tires are chosen. Clearance at the fender, suspension, and steering range deserves attention as well. Even when the sidewall shows a familiar size, the full wheel-and-vehicle combination still needs to make sense.
What should I inspect before driving a 2013 Ford Trucks Flex on new tires?
Before driving a 2013 Ford Trucks Flex on new tires, inspect the wheels for the correct diameter, check tire pressure, and confirm that all four tires match the intended fitment for the vehicle’s setup. It is also wise to look over the valve stems, wheel condition, and basic tread and sidewall condition on any remaining tire in service.
A short road test should follow, with attention paid to rubbing, vibration, or any change in steering feel. Rechecking inflation after the first drives helps catch small issues early. On a Flex with 20-inch tires, a quick visual check for fender and suspension clearance is especially worthwhile if the vehicle has custom wheels or stance changes.
How often should tires on a 2013 Ford Trucks Flex be inspected?
Tires on a 2013 Ford Trucks Flex should be inspected regularly, not just when replacement time arrives. A routine check for pressure loss, uneven wear, sidewall damage, embedded debris, and visible cracking helps catch problems before they become more serious. That applies whether the Flex is a daily driver or a lower-mileage specialty vehicle.
Monthly pressure checks are a sensible habit, and a closer inspection before longer trips adds another layer of caution. Vehicles that sit for extended periods still deserve attention because tire condition can change with age and storage. Looking over the tire shoulders and inner sidewalls is useful, especially on wider 20-inch fitments where issues may be less obvious.
