The 2019 Lincoln Trucks Navigator blends full-size SUV presence with modern luxury, making tire choice as much about preserving its road manners as matching the correct wheel setup. In this generation, the Navigator sits firmly in the premium touring end of the segment, where ride quality, stance, and wheel diameter all matter. This model uses radial tire fitments, with 275/55R20 on the Base model and 285/45R22 on the other covered sub-models. That creates a clear split between 20-inch and 22-inch applications rather than a simple one-size decision. Before choosing a tire, confirm the exact sub-model and wheel diameter already on the vehicle, especially if wheels have ever been changed.
Which Tire Size Is Right for The 2019 Lincoln Trucks Navigator
Two tire sizes apply to the 2019 Lincoln Trucks Navigator, and the correct choice depends first on the exact sub-model and wheel diameter. The Base model uses a 20-inch radial fitment, while the other covered Navigator and Navigator L trims use a 22-inch radial fitment. Before comparing tire options, confirm whether the vehicle is set up with 20-inch or 22-inch wheels and make sure any previous wheel changes have not altered the original size relationship.
The 275/55R20 size is a metric radial format: 275 indicates the nominal section width in millimeters, 55 is the aspect ratio, R identifies radial construction, and 20 is the rim diameter in inches. On the 2019 Lincoln Trucks Navigator, this size belongs to the Base sub-model and centers the decision on staying with the correct 20-inch wheel setup. Its dimensions make it a modern SUV fitment rather than a vintage sizing convention. Choose this size only after confirming the vehicle still carries the proper 20-inch wheels and has not been converted to a larger wheel package.
Fit(s): Black Label, L Black Label, L Reserve, L Select, Reserve, and Select
Construction: Radial|Rim: 22 in
The 285/45R22 size is also a metric radial, with 285 millimeters of nominal section width, a 45-series aspect ratio, radial construction, and a 22-inch rim diameter. On the 2019 Lincoln Trucks Navigator, this size applies to the covered Black Label, Reserve, Select, and Navigator L variants rather than every sub-model. It reflects a larger-wheel fitment that changes the selection process from simple size matching to careful wheel confirmation. Use this size only when the vehicle is one of the 22-inch applications and the wheel setup remains true to that configuration.
Sub-model fitment matters on the 2019 Lincoln Trucks Navigator because tire size changes with trim and wheel diameter. The Base model uses a different size than the other covered Navigator and Navigator L versions, so identifying the exact sub-model is the first step before comparing tires.

2019 Lincoln Trucks Navigator Base
The 2019 Lincoln Trucks Navigator Base uses the 275/55R20 radial fitment, making it the 20-inch application in this group. Tire selection starts with keeping that 20-inch size relationship intact and confirming the vehicle has not been changed to a different wheel package.
The 2019 Lincoln Trucks Navigator Black Label uses the 285/45R22 radial fitment rather than the smaller Base-model size. That means the buying decision centers on the correct 22-inch wheel setup and selecting a tire built for that larger-diameter application.
The 2019 Lincoln Trucks Navigator L Black Label uses the same 285/45R22 radial size as the other covered 22-inch Navigator trims. Keeping the correct fitment starts with confirming the existing wheel diameter and checking that any prior wheel change did not alter the intended tire size.
The 2019 Lincoln Trucks Navigator L Reserve uses a 285/45R22 radial tire fitment. For this sub-model, the key is matching the tire to the 22-inch wheel configuration and verifying overall wheel and tire compatibility before replacement.
The 2019 Lincoln Trucks Navigator L Select uses the 285/45R22 radial size. Tire selection is therefore less about choosing between multiple primary sizes and more about confirming the correct 22-inch setup on the vehicle before moving forward.
The 2019 Lincoln Trucks Navigator Reserve uses the 285/45R22 radial fitment. Owners should treat this as a 22-inch application first and verify the current wheel diameter before comparing replacement tires.
The 2019 Lincoln Trucks Navigator Select also uses the 285/45R22 radial size. That makes wheel confirmation especially important, since choosing between Navigator tire sizes comes down to the exact trim and wheel package already on the SUV.
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.
Frequently Asked Questions
Common 2019 Lincoln Trucks Navigator tire questions usually come down to the correct size by sub-model, the difference between the 20-inch and 22-inch fitments, and what to inspect before putting the SUV back into regular road use.
Tire Size & Fitment
What tire size fits a 2019 Lincoln Trucks Navigator?
The 2019 Lincoln Trucks Navigator uses two tire sizes depending on sub-model. The Base model uses 275/55R20, while the covered Black Label, Reserve, Select, and Navigator L variants use 285/45R22. Both are radial tire fitments, but they are tied to different wheel diameters and should not be treated as interchangeable primary sizes.
The practical first step is identifying the exact Navigator trim and confirming the wheel diameter currently on the vehicle. A used or modified SUV may no longer have its original wheels, so checking the sidewall size and the wheel itself helps avoid ordering a 20-inch tire for a 22-inch setup, or the reverse.
What size rim does a 2019 Lincoln Trucks Navigator use?
A 2019 Lincoln Trucks Navigator uses either a 20-inch or 22-inch rim, depending on sub-model. The 275/55R20 fitment uses a 20-inch rim, and the 285/45R22 fitment uses a 22-inch rim. The Base model is the 20-inch application, while the other covered trims use the 22-inch application.
Rim diameter should be confirmed before anything else because a 20-inch tire cannot be mounted on a 22-inch wheel, and a 22-inch tire cannot be mounted on a 20-inch wheel. If the Navigator has aftermarket wheels, inspect the actual wheel markings and current tire sidewall rather than relying only on trim assumptions.
Do all 2019 Lincoln Trucks Navigator sub-models use the same tire size?
No, the covered 2019 Lincoln Trucks Navigator sub-models do not all use the same tire size. The Base model uses 275/55R20, while the Black Label, Reserve, Select, L Black Label, L Reserve, and L Select use 285/45R22. The split is straightforward, but it does mean trim identification matters before choosing a replacement tire.
That difference also means the vehicle should be checked for its current wheel package before replacement. A Navigator that has been fitted with take-off wheels, aftermarket wheels, or a previous trim-level conversion may no longer match the original sub-model size, so the tire sidewall and wheel diameter deserve a quick verification.
Choosing the Right Tire
What should I consider when choosing a 275/55R20 tire for a 2019 Lincoln Trucks Navigator?
Choosing a 275/55R20 tire for a 2019 Lincoln Trucks Navigator starts with confirming that the vehicle is the Base model or still uses the correct 20-inch wheel setup. The size itself defines the basic fitment, but replacement decisions should also account for the tire's intended use, load suitability, and whether the Navigator is driven mainly in town, on the highway, or on longer family trips.
Wheel changes can complicate what looks like a simple size match, so inspect the current wheel diameter and compare the replacement tire carefully to the tire already on the vehicle. It also helps to look over tread wear patterns, since uneven wear may point to alignment or suspension issues that should be addressed before installing new tires.
What should I consider when choosing a 285/45R22 tire for a 2019 Lincoln Trucks Navigator?
A 285/45R22 tire belongs on the covered 22-inch 2019 Lincoln Trucks Navigator trims, so the first consideration is confirming that the SUV still has the proper 22-inch wheel setup. After that, selection comes down to choosing a tire that suits the vehicle's size, expected road use, and the owner's preference for ride character and appearance within that modern radial fitment.
The larger wheel diameter makes setup verification especially important if the Navigator has had wheel or suspension changes. Check the current tire size, inspect for adequate clearance at full steering lock, and make sure wear patterns do not suggest alignment or suspension problems before replacing a full set.
How do I choose between the available tire sizes for a 2019 Lincoln Trucks Navigator?
The choice between 275/55R20 and 285/45R22 is not a matter of preference on the 2019 Lincoln Trucks Navigator; it depends on the sub-model and wheel diameter already on the vehicle. The Base model uses the 20-inch fitment, while the other covered trims use the 22-inch fitment. Each size belongs to a different wheel package and should be selected accordingly.
That means the right process is to verify trim, inspect the existing tires, and confirm actual wheel diameter before shopping. If the Navigator has been modified, the current setup matters more than assumptions, and the safest approach is to match the tire to the wheel and available clearance rather than treating the two sizes as casual alternatives.
Restoration & Appearance
Does correct tire fitment matter for a 2019 Lincoln Trucks Navigator restoration?
Yes, correct tire fitment still matters on a 2019 Lincoln Trucks Navigator restoration or refurbishment, even though it is a much newer vehicle than a traditional collector car. The visual balance of the SUV, the relationship between tire and wheel diameter, and its intended road manners all depend on keeping the proper 275/55R20 or 285/45R22 fitment tied to the correct sub-model.
Appearance-oriented work on a modern luxury SUV can be undermined quickly by the wrong tire profile or the wrong wheel diameter. Owners trying to return a Navigator to period-appropriate presentation should confirm the original trim configuration, then match the tire size to that setup before focusing on cosmetic details elsewhere on the vehicle.
How does tire size affect the appearance of a 2019 Lincoln Trucks Navigator?
Tire size has a strong effect on the appearance of a 2019 Lincoln Trucks Navigator because the two fitments are built around different wheel diameters. A 275/55R20 creates a different visual proportion than a 285/45R22, even though both are correct within their own sub-model applications. The tire sidewall height and wheel size work together to shape the SUV's stance.
Using the wrong size can make the vehicle look out of place even before any driving issues are considered. Owners who care about keeping the Navigator's intended presentation should start with the proper trim-specific fitment, then confirm that the current wheels match that size instead of assuming any modern SUV tire will preserve the same look.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2019 Lincoln Trucks Navigator?
Yes, modifications can affect tire fitment on a 2019 Lincoln Trucks Navigator. Aftermarket wheels, suspension changes, lowering, and altered offsets can all change how a 275/55R20 or 285/45R22 tire sits in the wheel opening and how much clearance it has during steering and suspension travel. That matters even when the tire size itself looks close to the expected fitment.
A modified Navigator should be checked for actual wheel diameter, wheel width, and clearance at full lock before new tires are chosen. Looking at the present setup is especially important on used vehicles, since one trim's original tire size may no longer match what is currently installed on the SUV.
What should I inspect before driving a 2019 Lincoln Trucks Navigator on new tires?
Before driving a 2019 Lincoln Trucks Navigator on new tires, inspect the wheel size, confirm the tire size matches the vehicle's trim setup, and check inflation pressure carefully. It is also smart to look over the condition of the wheels, valve stems, and lug hardware so the new tires are being mounted on sound components rather than masking another problem.
A quick suspension and alignment review is worthwhile too, especially if the old tires showed uneven wear. Steering response, ride quality, and tread life are all affected by worn front-end parts or poor alignment, so a new set of tires should be paired with a close look at the rest of the Navigator's running gear.
How often should tires on a 2019 Lincoln Trucks Navigator be inspected?
Tires on a 2019 Lincoln Trucks Navigator should be inspected regularly, not just when replacement time arrives. Routine checks should include tread wear, sidewall condition, cuts, bulges, embedded objects, and any sign of slow air loss. Even on a newer luxury SUV, irregular wear can appear long before a tire is obviously worn out.
Monthly pressure checks and visual inspections are a sensible habit, with a closer review before a longer highway trip. A Navigator that spends time parked for long periods also deserves attention for flat spotting, age-related condition changes, and pressure loss, since infrequent use can hide tire issues until the vehicle returns to regular road duty.
