2019 Lincoln Trucks brought together a distinctly modern luxury SUV lineup, ranging from the compact MKC to the full-size Navigator, with the MKT and Nautilus filling different roles in between. That spread matters because tire sizing across 2019 Lincoln Trucks is not shared from one model to the next; each model uses its own combination of radial sizes tied to its wheel package and overall stance. In practical terms, the first decision is not brand or tread style, but confirming whether you have an MKC, MKT, Nautilus, or Navigator and then matching the correct rim diameter. Once that is settled, choosing the right tire becomes much more straightforward.
Which Tire Size Is Right for Your 2019 Lincoln Trucks
2019 Lincoln Trucks uses 11 tire sizes, and they vary by model rather than being shared across the full lineup. Every size here is a radial, so the key decision is identifying the correct model and wheel diameter first, then narrowing your choice within that size by brand, sidewall style, and intended use. Understanding that distinction before choosing a product saves time and helps ensure the right match.
Year(s): 2019|Fit(s): MKC|Construction: Radial|Rim: 18 in
235/50R18 is a metric radial size with a 235-millimeter section width, a 50-series aspect ratio, and an 18-inch rim diameter. This MKC-specific size is available from BFGoodrich and Nitto in Blackwall form, with W speed ratings up to 168 mph and load figures reaching 1,819 pounds at 50 psi on some versions. It suits drivers who want to stay with the correct 18-inch fitment for the MKC while choosing among performance-oriented radial options.
235/45R19 is a metric radial size that denotes a 235-millimeter section width, a 45-series profile, and a 19-inch rim diameter. This size is specific to certain MKC wheel packages and keeps the buyer focused on a 19-inch fitment rather than the 18-inch or 20-inch alternatives used elsewhere in the same model family. It is the right path when your MKC already carries the corresponding 19-inch wheel setup and you want to preserve the intended overall fit.
Year(s): 2019|Fit(s): MKC|Construction: Radial|Rim: 19 in
245/45R19 is a metric radial size with a 245-millimeter section width, a 45-series aspect ratio, and a 19-inch rim diameter. This MKC-specific size is available from BFGoodrich and Nitto in Blackwall form, and speed ratings vary by product between W at 168 mph and Y at 186-plus mph. It is a strong choice for an MKC owner who has the matching 19-inch wheel package and wants a broader selection of modern radial products within that fitment.
Year(s): 2019|Fit(s): MKC|Construction: Radial|Rim: 20 in
255/40R20 is a metric radial size that uses a 255-millimeter section width, a 40-series profile, and a 20-inch rim diameter. This size is specific to MKC applications on 20-inch wheels and is available in Blackwall form from BFGoodrich, with a Y speed rating up to 186-plus mph and a load figure of 1,819 pounds at 50 psi. It fits buyers who need the largest MKC wheel package covered here and want to keep the proper low-profile radial format for that setup.
235/55R19 is a metric radial size with a 235-millimeter section width, a 55-series aspect ratio, and a 19-inch rim diameter. This size is specific to the MKT and separates that model from the wider or larger-diameter fitments used on the rest of the 2019 Lincoln Trucks range. It is the correct direction when your MKT carries the 19-inch wheel package and you want to retain the intended diameter and profile relationship.
Year(s): 2019|Fit(s): MKT|Construction: Radial|Rim: 20 in
255/45R20 is a metric radial size that combines a 255-millimeter section width, a 45-series profile, and a 20-inch rim diameter. This MKT-specific size is available from BFGoodrich, Nitto, and Pro-Trac, with Blackwall and RWL sidewall styles and W speed ratings up to 168 mph across the products represented here. It gives MKT owners a useful mix of modern radial choices, especially if sidewall appearance matters as much as keeping the correct 20-inch fitment.
245/60R18 is a metric radial size with a 245-millimeter section width, a 60-series aspect ratio, and an 18-inch rim diameter. This size is specific to the Nautilus and points to the smaller-wheel setup within that model's range rather than the 20-inch or 21-inch alternatives. It is the right choice when your Nautilus rides on 18-inch wheels and you want to stay with the factory-style overall fitment approach for that configuration.
265/40R21 is a metric radial size that uses a 265-millimeter section width, a 40-series profile, and a 21-inch rim diameter. This size is specific to certain Nautilus wheel packages and stands apart from the 18-inch and 20-inch Nautilus fitments by its larger wheel diameter and lower-profile format. It is the proper route for a Nautilus already equipped with 21-inch wheels, where confirming that diameter is the critical first step.
245/50R20 is a metric radial size with a 245-millimeter section width, a 50-series aspect ratio, and a 20-inch rim diameter. This Nautilus-specific size belongs to the model's 20-inch wheel package and should not be confused with the wider 20-inch size used on the MKT or Navigator family. It is the sensible choice when your Nautilus has the matching 20-inch wheels and you want to keep the intended size relationship without changing wheel diameter.
275/55R20 is a metric radial size that denotes a 275-millimeter section width, a 55-series profile, and a 20-inch rim diameter. This size is specific to the Navigator and reflects the larger, heavier-duty luxury SUV end of the 2019 Lincoln Trucks range rather than the more compact fitments used on the MKC, MKT, or Nautilus. It is the correct path when your Navigator uses the 20-inch wheel package and you want to preserve the proper full-size SUV fitment.
285/45R22 is a metric radial size with a 285-millimeter section width, a 45-series aspect ratio, and a 22-inch rim diameter. This size is specific to Navigator applications on 22-inch wheels and is the largest wheel fitment used anywhere in the 2019 Lincoln Trucks lineup. It is the right choice only when the vehicle already carries the matching 22-inch wheels, since rim diameter is the deciding fitment point here.
Four Lincoln models are covered for 2019, and tire size changes significantly from one model to another. That means year and make alone are not enough here; buyers need to identify the exact model before narrowing down tire size, wheel diameter, and product options. Select a model below to explore model-specific fitment history and products.
2019 Lincoln Trucks MKC
The 2019 Lincoln MKC was Lincoln's compact luxury crossover, positioned as the smaller and more city-friendly entry in the brand's utility lineup. Its tire fitments span 18-, 19-, and 20-inch wheels, so wheel package matters as much as model identification when choosing the correct replacement size.
The 2019 Lincoln MKT served as a larger three-row crossover with a distinct profile and a comfort-oriented luxury mission. It uses either 19-inch or 20-inch wheels, and the correct tire choice depends on confirming which of those wheel packages is on the vehicle now.
The 2019 Lincoln Nautilus marked the transition from the MKX name to a more cohesive Lincoln SUV identity, with a strong emphasis on upscale road manners and contemporary styling. Its fitments mount on 18-, 20-, or 21-inch wheels, so the wheel diameter is the key detail to confirm before comparing tire options.
The 2019 Lincoln Navigator was Lincoln's flagship full-size luxury SUV, known for its substantial presence and premium long-distance character. Its tire sizes mount on 20-inch or 22-inch wheels, reflecting the larger wheel and tire packages expected on a modern body-on-frame luxury utility vehicle.
Nineteen products are available across 11 tire sizes for 2019 Lincoln Trucks vehicles. 235/50R18 has 4 radial options from BFGoodrich and Nitto in Blackwall; 245/45R19 has 3 radial options from BFGoodrich and Nitto in Blackwall; 255/40R20 has 1 radial BFGoodrich Blackwall option; 255/45R20 has 4 radial options from BFGoodrich, Nitto, and Pro-Trac in Blackwall and RWL. Confirm your exact size first, since speed ratings can vary within a single size.
These FAQs focus on the model-specific tire sizing used across 2019 Lincoln Trucks, how modern metric radial codes differ by wheel package, and what to confirm about sidewall style, speed rating, and long-term care before putting miles on a luxury SUV.
Size Basics & Fitment
What tire sizes fit 2019 Lincoln Trucks vehicles?
2019 Lincoln Trucks vehicles use 11 sizes spread across four models. MKC uses 235/50R18, 235/45R19, 245/45R19, and 255/40R20; MKT uses 235/55R19 and 255/45R20; Nautilus uses 245/60R18, 245/50R20, and 265/40R21; Navigator uses 275/55R20 and 285/45R22. These are all radial sizes, and the rim diameters span 18, 19, 20, 21, and 22 inches depending on model and wheel package.
The practical takeaway is that 2019 Lincoln Trucks fitment is model-specific, not year-make-wide. Before choosing a tire, confirm both the model name and the wheel diameter currently on the vehicle, then compare the exact size on the sidewall to the vehicle's present setup. That is especially important on MKC and Nautilus models, where more than one wheel diameter was used.
What does 235/50R18 mean on a 2019 Lincoln Trucks tire?
On a 2019 Lincoln Trucks MKC, 235/50R18 means the tire is 235 millimeters wide, has a 50-series aspect ratio, and fits an 18-inch rim. The R indicates radial construction, which is the construction used across all 2019 Lincoln Trucks sizes covered here. In available products for this size, rim width ranges run from 6.5 to 8.5 inches, with W speed ratings appearing on the products represented in this fitment.
That code matters because each part of it affects fit and wheel compatibility. A 235/50R18 should only be considered for an MKC already using the corresponding 18-inch wheel package, and it should not be treated as interchangeable with the 19-inch or 20-inch MKC sizes. If you are replacing one tire size with the same size, confirm the wheel width and compare the new tire's load and speed markings to your driving needs.
Do all 2019 Lincoln Trucks models use the same tire size?
No, 2019 Lincoln Trucks models do not share a single tire size across the lineup. The compact MKC, larger MKT, mid-size Nautilus, and full-size Navigator each use their own tire sizes, and some models use several different wheel and tire combinations within the same model year. That means a 2019 Lincoln Trucks badge alone is not enough to identify the correct fitment.
Model identification is the first step, and wheel diameter is the second. Navigator owners will be choosing between 20-inch and 22-inch fitments, Nautilus owners between 18-, 20-, and 21-inch fitments, MKT owners between 19 and 20 inches, and MKC owners among 18-, 19-, and 20-inch packages. Checking the tire sidewall already on the vehicle is usually the fastest way to narrow it down.
Buying the Right Tire
What sidewall styles are available for 2019 Lincoln Trucks tires?
Most 2019 Lincoln Trucks tire options represented here use a Blackwall sidewall, which suits the clean, understated look expected on a late-model Lincoln SUV. One size, 255/45R20 for the MKT, also appears with an RWL sidewall from Pro-Trac. That gives MKT owners a visible styling choice that the other covered sizes do not currently share in this product mix.
For a factory-like appearance on a 2019 Lincoln Trucks model, Blackwall is generally the more natural visual fit. An RWL tire can add a more custom or sport-oriented look, but it changes the appearance more noticeably than a plain black sidewall. If looks matter as much as fitment, compare sidewall style before making a final size-and-brand decision.
What brands make tires for 2019 Lincoln Trucks vehicles?
BFGoodrich, Nitto, and Pro-Trac appear across the 2019 Lincoln Trucks sizes that currently have product coverage here. 235/50R18 is available from BFGoodrich and Nitto, 245/45R19 is available from BFGoodrich and Nitto, 255/40R20 is available from BFGoodrich, and 255/45R20 is available from BFGoodrich, Nitto, and Pro-Trac. All of those options are radial tires, with Blackwall dominating and RWL appearing in the 255/45R20 group.
Brand choice becomes relevant only after the exact tire size is confirmed. Some sizes offer a wider mix of names and product lines, while others are much narrower, especially when the wheel diameter gets more specialized. Once the fitment is settled, compare sidewall appearance, speed rating, load marking, and intended driving use rather than assuming every brand offers the same configuration in every size.
What is the difference between BFGoodrich and Nitto choices for 2019 Lincoln Trucks 235/50R18 tires?
In 235/50R18 for the 2019 Lincoln Trucks MKC, BFGoodrich and Nitto both offer radial Blackwall tires with W speed ratings. BFGoodrich appears in several product lines in this size, while Nitto's NT555 G2 carries an XL 101W marking, a load figure of 1,819 pounds at 50 psi, and a rim width range centered around 6.5 to 8.5 inches. BFGoodrich options in this size also use 18-inch fitment and include products with similar rim width coverage.
The real distinction is less about basic fit and more about the specific product character within the same size. If you are comparing these two brands, focus on the exact sidewall marking, load index, and any XL designation, then match those details to how the MKC is driven and equipped. Staying within 235/50R18 keeps the fitment correct while allowing some flexibility in product personality.
Fitting & Setup
What rim width do 2019 Lincoln Trucks tires require?
Rim width guidance is available for several 2019 Lincoln Trucks sizes with active product coverage. 235/50R18 products generally fit 6.5 to 8.5-inch rims, 245/45R19 products generally fit 7.5 to 9-inch rims, 255/40R20 fits 8.5 to 10-inch rims, and 255/45R20 fits 8.0 to 9.5-inch rims. Each of those sizes also uses its own specific rim diameter, so width and diameter both need to be checked together.
That matters most when a vehicle has had wheels changed or upgraded. A tire can share the correct diameter but still be a poor match if the wheel is too narrow or too wide for the intended size. Before replacing a tire on a 2019 Lincoln Trucks model, verify the actual wheel dimensions rather than assuming every factory-looking wheel matches the same width range.
Do 2019 Lincoln Trucks tires require inner tubes?
The 2019 Lincoln Trucks products represented here are modern radial sizes without tube-type markings, so they are tubeless in normal use. Size descriptions such as 235/50ZR18, 245/45ZR19, 255/40ZR20, and 255/45ZR20 appear without TT markings, which supports that tubeless setup. That matches what buyers would expect from late-model luxury SUV applications on modern wheels.
Even with tubeless tires, valve stem condition still matters. When replacing tires on a 2019 Lincoln Trucks model, inspect or replace the stems as needed and make sure the wheel sealing surface is clean and undamaged. A slow air loss problem on a modern SUV is often tied to a stem or wheel-seal issue rather than the tire casing itself.
Maintenance, Storage & Longevity
How should I store a 2019 Lincoln Trucks when the tires are fitted?
A 2019 Lincoln Trucks should be stored away from direct sunlight, standing moisture, and ozone sources such as electric motors, air compressors, and welders. Keep the tires properly inflated during storage, and if the vehicle will sit for extended periods, move it occasionally or use stands to reduce prolonged contact stress on one spot of the tread. Radial tires resist static distortion better than old bias-ply designs, but long idle periods are still hard on any collector or low-use vehicle.
Good storage habits help preserve both appearance and service life. A luxury SUV such as an MKC, Nautilus, MKT, or Navigator may not accumulate many miles quickly, but time and environment still age the tires. Clean, dry indoor storage and periodic pressure checks will do more for tire longevity than simply covering the vehicle and leaving it untouched.
How long do tires on a 2019 Lincoln Trucks typically last?
On a low-use 2019 Lincoln Trucks vehicle, tire age is usually more important than mileage alone. A sound rule is to begin careful evaluation around five to seven years of age and to treat ten years as a point where replacement deserves very serious consideration, even if tread depth still looks acceptable. The DOT date code on the sidewall is the best way to track the tire's true age.
That guideline is especially useful for luxury SUVs that may see seasonal or occasional use rather than daily commuting. Heat cycles, sunlight, storage conditions, and time all affect the rubber and internal structure long before the tread appears worn out. If the vehicle still wears older tires, check the date code first and use that as part of your replacement decision.
How often should tires on a 2019 Lincoln Trucks be inspected?
Tires on a 2019 Lincoln Trucks should be inspected before every drive and again before any longer highway outing. Look for sidewall cracking, punctures, bulges, irregular wear, low pressure, and anything embedded in the tread. On vehicles that sit often, pressure loss can happen gradually enough that the driver does not notice it until the next extended trip.
A quick inspection is inexpensive insurance on a modern luxury SUV, especially one running larger 20-, 21-, or 22-inch wheel packages. Include the spare if the vehicle still carries one, and do not overlook valve stems and TPMS-related service points during routine checks. Catching a small issue in the garage is far better than discovering it at interstate speed.
Safety & Road Use
Are 2019 Lincoln Trucks tires safe for highway driving?
Yes, the 2019 Lincoln Trucks tire sizes represented here are modern radial fitments intended for normal road use, and the products with visible speed ratings include W and Y markings. W-rated tires are rated up to 168 mph, while Y-rated tires are rated for 186-plus mph. Those ceilings are far above ordinary U.S. highway speeds, so in real-world use the condition, age, inflation, and load of the tire usually matter more than the headline speed symbol.
Highway safety still depends on the complete vehicle, not just the tire. A well-maintained 2019 Lincoln Trucks SUV with fresh, correctly sized tires and proper inflation is in a much better position than one riding on aged rubber with unknown history. Match the tire size to the exact model and wheel package, then check age and condition before placing trust in the speed rating alone.
What inflation pressure should I use for 2019 Lincoln Trucks tires?
Inflation pressure on a 2019 Lincoln Trucks should follow the vehicle manufacturer's door-jamb or owner's manual recommendation for the exact model and tire size, not a generic figure shared across the lineup. Some tire products in these sizes also carry their own maximum load and pressure markings, such as 1,819 pounds at 50 psi for certain 235/50R18, 255/40R20, and 255/45R20 applications, and 1,874 pounds at 50 psi for one 245/45R19 application. Those figures describe the tire's rated limit, not necessarily the vehicle's everyday operating pressure.
The safest approach is to use the vehicle's factory pressure target as your starting point and the tire sidewall's maximum pressure only as a load-capacity reference. Do not transfer a pressure number from one 2019 Lincoln Trucks model or size to another, because the MKC, MKT, Nautilus, and Navigator all use different sizes and carry different loads. Pressure should always match the exact vehicle and tire combination.
What should I check before taking a 2019 Lincoln Trucks on a longer drive?
Before a longer trip in a 2019 Lincoln Trucks, inspect each tire for cracks, cuts, bulges, punctures, uneven wear, and proper cold inflation pressure. Confirm that all four tires match the intended size for the model and wheel package, and check the age code if the vehicle has been driven only occasionally. On larger luxury SUVs, a tire that looks acceptable at a glance can still be aging out internally if it has spent years in storage or low-use service.
Tires are only one part of a smart pre-trip check, but they are one of the easiest places to prevent trouble. Also examine the spare, valve stems, and wheel condition, then move on to brakes, fluids, suspension, and battery health. A 2019 Lincoln Trucks model is fully capable of long-distance road use when the basics are verified before departure.
