2014 Lincoln Trucks brought Lincoln’s luxury approach into a crossover-and-SUV lineup that ranged from the three-row MKT to the midsize MKX and the full-size Navigator. Even within one model year, these vehicles served very different purposes, from car-based comfort to heavier-duty luxury utility. Tire sizing across 2014 Lincoln Trucks varies by model rather than carrying one shared fitment, with seven distinct radial sizes spread across three model lines and three rim diameters. That means the first step is confirming whether you have an MKT, MKX, or Navigator, then matching the exact wheel diameter and tire size already on the vehicle before narrowing your product choice.
Which Tire Size Is Right for Your 2014 Lincoln Trucks
Seven tire sizes are used across 2014 Lincoln Trucks, and they vary by model rather than being shared across the full range. Because every size here is a radial but the lineup spans 18-, 19-, 20-, and 22-inch rim diameters, the real decision starts with confirming your exact model and wheel diameter. Understanding that distinction before choosing a product saves time and helps ensure the right match.
235/55R19 is a metric radial size with a 235-millimeter section width, a 55-series aspect ratio, and fitment for a 19-inch wheel. This size is specific to the MKT rather than universal across 2014 Lincoln Trucks. It suits buyers who need the exact MKT wheel fitment first, then can compare product details within that same size on the next step.
Year(s): 2014|Fit(s): MKT|Construction: Radial|Rim: 20 in
255/45R20 is a metric radial size with a 255-millimeter section width, a 45-series aspect ratio, and fitment for a 20-inch wheel. This MKT-specific size is available from BFGoodrich, Nitto, and Pro-Trac in Blackwall and RWL sidewall styles, and products in this size carry W speed ratings with a 168 mph ceiling. It is the size to focus on when your MKT already uses 20-inch wheels and you want a wider, lower-profile radial fitment.
245/50R20 is a metric radial size with a 245-millimeter section width, a 50-series aspect ratio, and fitment for a 20-inch wheel. This size is specific to the MKX rather than shared across the other 2014 Lincoln Trucks models. It is the right starting point for MKX owners running 20-inch wheels who want to keep the factory-style wheel diameter consistent.
245/60R18 is a metric radial size with a 245-millimeter section width, a 60-series aspect ratio, and fitment for an 18-inch wheel. This size belongs to the MKX only, so it should not be treated as interchangeable across the rest of the 2014 Lincoln Trucks range. It is the correct path when your MKX is equipped with 18-inch wheels and you need to preserve that wheel diameter.
265/40R22 is a metric radial size with a 265-millimeter section width, a 40-series aspect ratio, and fitment for a 22-inch wheel. This size is specific to certain MKX wheel packages and is not used across the full 2014 Lincoln Trucks lineup. It is the size to choose only after confirming that your MKX is actually fitted with 22-inch wheels.
255/70R18 is a metric radial size with a 255-millimeter section width, a 70-series aspect ratio, and fitment for an 18-inch wheel. This size is Navigator-specific, reflecting the full-size SUV’s different tire profile and wheel package compared with the MKT and MKX. It is the right fitment path when your Navigator runs 18-inch wheels and you want to stay with that taller-profile radial size.
275/55R20 is a metric radial size with a 275-millimeter section width, a 55-series aspect ratio, and fitment for a 20-inch wheel. This size is used on the Navigator only, so buyers should confirm model and wheel diameter before assuming any 20-inch Lincoln Trucks tire will interchange. It fits Navigator applications that use the larger 20-inch wheel package and need that exact size match.
Three 2014 Lincoln Trucks models are covered here: MKT, MKX, and Navigator. They do not share one common tire size, so identifying the exact model matters before moving on to a size or product choice. Select your model below to see model-specific fitment history and tire options in more detail.
2014 Lincoln Trucks MKT
The 2014 Lincoln MKT was Lincoln’s full-size luxury crossover, known for its long roofline, three-row layout, and car-based driving character. Its tires mount on either 19-inch or 20-inch wheels, so wheel diameter is the first thing to confirm before choosing a replacement size.
The 2014 Lincoln MKX was Lincoln’s midsize luxury crossover, positioned as a more personal and style-oriented SUV than the larger MKT. Its fitments span 18-, 20-, and 22-inch wheels, making wheel size confirmation especially important on this model.
The 2014 Lincoln Navigator remained Lincoln’s traditional body-on-frame luxury SUV, with a larger footprint and a more truck-based character than the brand’s crossover models. Its tires mount on either 18-inch or 20-inch wheels, and that distinction determines which size family applies.
Four products are available across one tire size for 2014 Lincoln Trucks vehicles. The 255/45R20 has four radial choices from BFGoodrich, Nitto, and Pro-Trac, with Blackwall and RWL sidewall styles. Confirm your exact size first, since product coverage does not span every 2014 Lincoln Trucks fitment.
These answers cover how tire sizing changes between the 2014 Lincoln Trucks MKT, MKX, and Navigator, what the metric size codes mean, which brands and sidewall styles are available in 255/45R20, and what to inspect before regular use or storage.
Size Basics & Fitment
What tire sizes fit 2014 Lincoln Trucks vehicles?
2014 Lincoln Trucks vehicles use seven sizes across three models. The MKT uses 235/55R19 and 255/45R20, the MKX uses 245/60R18, 245/50R20, and 265/40R22, and the Navigator uses 255/70R18 and 275/55R20. These are all radial sizes, but they do not share one common wheel diameter across the lineup, since 18-, 19-, 20-, and 22-inch wheels are all represented.
That means year and make alone are not enough to choose tires for 2014 Lincoln Trucks. Start by identifying whether you have an MKT, MKX, or Navigator, then verify the wheel diameter already on the vehicle. Once the model and wheel size are confirmed, you can narrow the search to the exact tire size that belongs to that fitment rather than comparing similar-looking sizes that mount on different wheels.
What does 255/45R20 mean on a 2014 Lincoln Trucks tire?
On a 2014 Lincoln Trucks tire, 255/45R20 is a metric radial size code. The 255 is the nominal section width in millimeters, 45 is the aspect ratio, R identifies radial construction, and 20 is the wheel diameter in inches. Within the 2014 Lincoln Trucks range, that size applies to the MKT and mounts on a 20-inch wheel.
Understanding the code helps prevent one of the most common ordering mistakes: matching width while missing wheel diameter or profile. A 255/45R20 cannot substitute for an 18-inch or 19-inch fitment, and it should not be confused with the Navigator’s different 20-inch size. If your MKT has 20-inch wheels, 255/45R20 is the exact size family to investigate further.
Do all 2014 Lincoln Trucks models use the same tire size?
No, 2014 Lincoln Trucks models do not use the same tire size. The MKT, MKX, and Navigator each have their own fitment patterns, and every size in this year-make group is tied to only one model line. Even when two models use the same wheel diameter, the tire size itself can still differ, as seen with 20-inch applications across the MKT, MKX, and Navigator.
That makes model identification just as important as reading the size on the sidewall. A buyer choosing for an MKX should not assume a 20-inch MKT or Navigator tire will interchange simply because the wheel diameter matches. Check the model badge, confirm the current wheel diameter, and compare the exact tire code before moving to product selection.
Buying the Right Tire
What sidewall styles are available for 2014 Lincoln Trucks tires?
Sidewall style variety appears in the 255/45R20 fitment used on the 2014 Lincoln Trucks MKT. That size is available in both Blackwall and RWL form, with Blackwall options from BFGoodrich and Nitto and an RWL option from Pro-Trac. The other 2014 Lincoln Trucks sizes shown here are best treated by exact size first, then by whatever sidewall treatment is offered within that fitment.
For a modern luxury crossover such as the 2014 Lincoln Trucks MKT or MKX, Blackwall is usually the more understated look and the closer visual fit with factory-era presentation. RWL adds a more overt performance-style appearance that some owners prefer on custom or more personalized builds. If visual authenticity matters, compare the sidewall treatment to period photos of your exact model and wheel package before choosing.
What brands make tires for 2014 Lincoln Trucks vehicles?
The 255/45R20 fitment used on the 2014 Lincoln Trucks MKT is available from BFGoodrich, Nitto, and Pro-Trac. BFGoodrich appears with g-Force Comp 2 AS and g-Force Sport Comp 2, Nitto with the NT555 G2, and Pro-Trac with the Street Pro III. All of those products are radial 20-inch tires in the same size family.
Brand choice within a single size usually comes down to the combination of styling, series preference, and secondary specification details such as sidewall treatment or load marking. The key is to stay inside the correct size first. Once you know your 2014 Lincoln Trucks model and tire code, compare brands only within that exact fitment rather than crossing over to a different model’s size.
What is the difference between BFGoodrich g-Force and Nitto NT555 G2 for the 2014 Lincoln Trucks MKT?
For the 2014 Lincoln Trucks MKT in 255/45R20, BFGoodrich g-Force and Nitto NT555 G2 share the same basic 20-inch radial size and carry W speed ratings, which correspond to a 168 mph ceiling. The BFGoodrich options show an 8.0 to 9.5 inch rim-width range and one version carries a max load figure of 1,819 pounds at 51 psi. The Nitto product uses the same size family and speed rating, with an XL 105W marking.
That means the comparison is less about fitment and more about the specific product character you want within the same size. Sidewall appearance, series preference, and how closely the wheel matches the published rim-width range all matter. If your MKT already runs 20-inch wheels, compare those product-level details carefully instead of assuming all 255/45R20 tires are interchangeable in every respect.
Fitting & Setup
What rim width do 2014 Lincoln Trucks tires require?
Rim-width guidance is available for the 255/45R20 fitment used on the 2014 Lincoln Trucks MKT. BFGoodrich products in that size call for an 8.0 to 9.5 inch rim-width range. Other 2014 Lincoln Trucks sizes here should still be matched to the exact wheel diameter and then checked against the individual tire’s approved wheel range before final selection.
Rim width matters because the same tire size can behave differently if mounted on a wheel that is too narrow or too wide for the product’s design range. If your 2014 Lincoln Trucks MKT uses 255/45R20, confirm the wheel falls within that 8.0 to 9.5 inch span. For any other size, compare your actual wheel to the product’s approved range before mounting.
Do 2014 Lincoln Trucks tires require inner tubes?
The 255/45R20 products available for 2014 Lincoln Trucks are tubeless radials rather than tube-type tires. Their sidewall sizing uses modern radial markings without a tube-type designation, which is typical for this kind of late-model crossover fitment. The rest of the 2014 Lincoln Trucks sizes in this year-make group are also modern radial applications rather than vintage tube-type designs.
Even so, tubeless operation still depends on the wheel and valve stem being in proper condition. Before fitting replacement tires to a 2014 Lincoln Trucks wheel, inspect the bead seats for corrosion or damage and replace worn valve stems. If a wheel has been refinished, repaired, or modified, verify that it is still suitable for tubeless service before mounting the tire.
Maintenance, Storage & Longevity
How should I store a 2014 Lincoln Trucks when the tires are fitted?
A 2014 Lincoln Trucks vehicle should be stored in a cool, dry place away from direct sunlight, electric motors, battery chargers, welders, and other ozone-producing equipment. Keep the tires clean, maintain inflation, and move the vehicle occasionally so one section of the tread and sidewall does not carry the same static load for months at a time. Radials generally tolerate storage better than older bias-ply designs, but they still age from heat, light, and ozone exposure.
If the vehicle will sit for a long season, many collectors either roll it periodically or support it in a way that reduces constant load on the tires without leaving the suspension hanging unnaturally. Flat, dry flooring is preferable to bare ground. A simple storage routine does more to preserve sidewalls and ride quality than waiting until cracks or vibration appear after the vehicle goes back into service.
How long do tires on a 2014 Lincoln Trucks typically last?
Tires on a 2014 Lincoln Trucks vehicle should be evaluated by age as much as by tread depth, especially on lower-mileage luxury SUVs and crossovers that may spend long periods parked. A practical collector and enthusiast rule is to inspect closely after five to seven years and to treat around ten years as a strong replacement point, even if the tread still looks usable. The DOT date code on the sidewall gives the tire’s week and year of manufacture.
That approach is more useful than relying on mileage alone because many 2014 Lincoln Trucks vehicles accumulate age faster than wear. Heat cycles, UV exposure, and storage conditions can harden the rubber long before the tread is gone. If steering feel changes, cracks appear, or the tires no longer hold pressure consistently, age has become just as important as tread life in the replacement decision.
How often should tires on a 2014 Lincoln Trucks be inspected?
Tires on a 2014 Lincoln Trucks vehicle should be inspected before every drive and given a more thorough look before any longer highway outing. Check for visible cracking, cuts, bulges, uneven wear, embedded debris, and any sign that pressure is dropping between uses. Because these are modern radial applications, also pay attention to shoulder wear and tread condition that can point to alignment or suspension issues.
Routine inspection is especially important on luxury SUVs and crossovers because extra weight can magnify the effects of underinflation or neglected wear. A quick visual check takes only a minute, but it often catches a problem before it turns into vibration, heat buildup, or roadside trouble. Include the spare in the same routine so it is usable if one of the road tires has to come off unexpectedly.
Safety & Road Use
Are 2014 Lincoln Trucks tires safe for highway driving?
2014 Lincoln Trucks tires in the available 255/45R20 fitment include W-rated products, and a W speed rating carries a 168 mph ceiling. That is far beyond ordinary U.S. highway speeds, so the tire’s speed category is not the limiting factor in normal road use for a luxury crossover such as the MKT. Real-world safety depends more on correct size, proper inflation, age, load condition, and the mechanical health of the vehicle.
A newer-looking tire is not automatically a safe tire if it is underinflated, damaged, or aged out. Before any sustained highway driving in a 2014 Lincoln Trucks vehicle, check pressure cold, inspect the sidewalls and tread, and make sure the suspension and brakes are in sound condition. Safe highway use is the result of the whole package working together, not the tire size code alone.
What inflation pressure should I use for 2014 Lincoln Trucks tires?
Inflation pressure for 2014 Lincoln Trucks should follow the vehicle manufacturer’s recommendation for the exact model and tire size, then be checked against the tire maker’s own markings where relevant. In the available 255/45R20 products, one BFGoodrich option carries a maximum load of 1,819 pounds at 51 psi. That figure is the tire’s maximum rated condition, not a blanket operating pressure for every 2014 Lincoln Trucks fitment.
Use the door-jamb placard or owner’s manual as the starting point for normal service pressure on your MKT, MKX, or Navigator. Then make sure the tire itself is appropriate for that load and pressure range. Do not transfer one pressure figure from a 255/45R20 performance-style tire to an 18-inch or 22-inch Lincoln Trucks fitment, because each size has its own construction and load characteristics.
What should I check before taking a 2014 Lincoln Trucks on a longer drive?
Before a longer drive in a 2014 Lincoln Trucks vehicle, inspect all four road tires and the spare for cracking, cuts, bulges, irregular wear, and proper cold inflation. Confirm that the sidewall size matches the wheel package on the vehicle, and look at the valve stems for age or damage. If the tires are older, also note any vibration, hardening, or tread separation symptoms during the first miles of driving.
A thorough pre-drive check should go beyond the tires on any older luxury SUV or crossover that may see intermittent use. Brakes, fluids, battery condition, lighting, and suspension health all deserve attention before distance travel. When the tire inspection is handled first, it becomes much easier to spot whether a shake or pull on the road is a tire issue or something else in the chassis.
