The 2020 Lincoln Trucks Navigator sits firmly in the modern full-size luxury SUV class, blending traditional body-on-frame capability with the quiet, upscale road manners buyers expect from a flagship Lincoln. For many owners, tire choice is less about vintage styling and more about preserving the Navigator’s intended stance, ride quality, and wheel presence. This model uses two primary radial tire sizes, 275/55R20 and 285/45R22, with fitment tied to the exact sub-model. The real decision is confirming whether the vehicle is equipped with the 20-inch or 22-inch wheel package, then choosing a tire that suits daily driving, appearance, and load-carrying expectations.
Which Tire Size Is Right for The 2020 Lincoln Trucks Navigator
Two tire sizes apply to the 2020 Lincoln Trucks Navigator, and the difference comes down to sub-model and wheel diameter. The first step is confirming whether the vehicle uses the 20-inch or 22-inch wheel setup, because 275/55R20 and 285/45R22 are not interchangeable primary fitments. Once that is settled, the focus shifts to selecting the right radial tire within the correct size for the vehicle’s intended use and overall setup.
275/55R20 is a metric radial size in which 275 identifies the nominal section width in millimeters, 55 is the aspect ratio, R indicates radial construction, and 20 is the wheel diameter in inches. On the 2020 Lincoln Trucks Navigator, this size belongs with the 20-inch wheel fitment rather than the 22-inch setup used elsewhere in the range. Its dimensions place it in the modern SUV tire category, making wheel confirmation especially important before selection. This is the size to evaluate when the vehicle retains its 20-inch wheels and has not been changed to a different wheel package.
Fit(s): Black Label, L Black Label, L Reserve, and Reserve
Construction: Radial|Rim: 22 in
285/45R22 is a metric radial size where 285 is the nominal section width in millimeters, 45 is the aspect ratio, R denotes radial construction, and 22 is the wheel diameter in inches. On the 2020 Lincoln Trucks Navigator, this size serves the 22-inch wheel fitment used by several upper sub-models. It carries a wider, lower-profile sizing character than the 20-inch option, so matching it to the actual wheel package matters more than matching by overall appearance alone. This is the size to consider when the Navigator is equipped with factory-style 22-inch wheels or an equivalent wheel setup.
Sub-model fitment matters on the 2020 Lincoln Trucks Navigator because tire size changes with the wheel package. The Base model uses a different size than the Black Label, Reserve, and long-wheelbase L variants, so identifying the exact trim is the first step before comparing tires.

2020 Lincoln Trucks Navigator Base
The 2020 Lincoln Trucks Navigator Base uses the 275/55R20 radial tire size on its 20-inch wheel fitment. That makes wheel confirmation straightforward, and the main task becomes selecting the right tire within that size for the vehicle’s road use, ride expectations, and any wheel changes made over time.
The 2020 Lincoln Trucks Navigator Black Label uses the 285/45R22 radial tire size with a 22-inch wheel setup. Tire selection starts with staying in that size unless the vehicle has been modified, then checking that the chosen tire suits the wheel dimensions and intended use.
The 2020 Lincoln Trucks Navigator L Black Label also uses the 285/45R22 radial tire size on a 22-inch rim. For this long-wheelbase version, the practical concern is confirming the actual wheel package on the vehicle and avoiding any assumption that the smaller 20-inch fitment applies.
The 2020 Lincoln Trucks Navigator L Reserve uses the 285/45R22 radial tire size. That keeps tire selection centered on the 22-inch wheel package, with attention paid to maintaining proper wheel compatibility and verifying clearance if aftermarket wheels or suspension changes are present.
The 2020 Lincoln Trucks Navigator Reserve uses the 285/45R22 radial tire size rather than the 20-inch Base-model fitment. Choosing correctly starts with confirming the Reserve trim and wheel diameter, then selecting a tire built for the vehicle’s combination of luxury use, highway driving, and full-size SUV weight.
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
Navigator owners usually need to confirm the exact trim and wheel diameter before choosing tires. The questions below focus on size fitment, 20-inch versus 22-inch wheels, selection priorities, and the basic checks that matter before road use.
Tire Size & Fitment
What tire size fits a 2020 Lincoln Trucks Navigator?
The 2020 Lincoln Trucks Navigator uses one of two radial tire sizes: 275/55R20 or 285/45R22. The correct size depends on the sub-model and wheel package. Navigator Base models use 275/55R20, while Black Label, Reserve, L Black Label, and L Reserve models use 285/45R22.
The key step is matching the tire to the actual wheel diameter on the vehicle. A 20-inch fitment and a 22-inch fitment are different starting points, even though both belong to the same model year and nameplate. If the Navigator has had wheel changes, confirm the wheel size on the vehicle before ordering replacement tires.
What size rim does a 2020 Lincoln Trucks Navigator use?
A 2020 Lincoln Trucks Navigator uses either a 20-inch or 22-inch rim, depending on sub-model. The Base model uses the 20-inch setup with 275/55R20 tires, while Black Label, Reserve, and the L variants use the 22-inch setup with 285/45R22 tires.
Rim diameter should be confirmed before focusing on tread pattern or brand. A tire marked for a 20-inch wheel cannot be treated as the same fitment as one built for a 22-inch wheel. Checking the wheel itself is especially important on SUVs that may have received aftermarket wheels or dealer-installed wheel packages.
Do all 2020 Lincoln Trucks Navigator sub-models use the same tire size?
No. The 2020 Lincoln Trucks Navigator Base uses 275/55R20, while the Black Label, Reserve, L Black Label, and L Reserve use 285/45R22. Both are radial tire sizes, but they belong to different wheel diameters and different trim-level fitment groups.
That difference means the trim name matters before comparing replacement options. It also means a buyer should not assume that any tire advertised for a 2020 Navigator applies across the entire lineup. Confirming the exact sub-model and wheel package first prevents choosing a tire built for the wrong rim diameter.
Choosing the Right Tire
What should I consider when choosing a 275/55R20 tire for a 2020 Lincoln Trucks Navigator?
Start by confirming that the vehicle is a 2020 Lincoln Trucks Navigator Base with the 20-inch wheel setup. Once the size is verified, the main considerations are keeping the correct 275/55R20 sizing, choosing a tire suited to full-size SUV use, and matching the tire to the vehicle’s actual wheel dimensions.
Beyond size, think about how the Navigator is driven. A daily-driven luxury SUV may call for different priorities than a lightly used vehicle kept mostly for family trips or highway travel. Wheel changes, suspension alterations, and heavy-load use can all affect what tire characteristics deserve the closest attention before purchase.
What should I consider when choosing a 285/45R22 tire for a 2020 Lincoln Trucks Navigator?
The first step is confirming that the vehicle uses the 22-inch wheel package found on Black Label, Reserve, L Black Label, and L Reserve models. After that, the correct approach is to stay with the 285/45R22 size unless the vehicle has been intentionally reconfigured with different wheels and a properly matched tire setup.
Because this size pairs a wider section with a lower profile on a larger rim, wheel condition and correct wheel specification become especially important. Owners should also think about ride expectations, highway use, and whether the Navigator remains stock. Any aftermarket wheel or suspension change should be checked carefully before replacement.
How do I choose between the available tire sizes for a 2020 Lincoln Trucks Navigator?
The two sizes are not simply two preferences for the same vehicle setup. A 2020 Lincoln Trucks Navigator Base uses 275/55R20, while the other covered sub-models use 285/45R22. The correct choice comes from the trim and wheel package already on the vehicle, not from appearance alone.
That makes selection more about identification than comparison. Check the trim level, verify the wheel diameter, and read the current tire sidewall before moving further. If the vehicle has been modified, use the actual wheel dimensions and available clearance as the guide rather than relying only on the original sub-model fitment.
Restoration & Appearance
Does correct tire fitment matter for a 2020 Lincoln Trucks Navigator restoration or refurbishment?
Yes. Even on a modern luxury SUV like the 2020 Lincoln Trucks Navigator, correct tire fitment matters when the goal is to return the vehicle to a proper, well-sorted presentation. The right size preserves the intended relationship between wheel diameter, tire profile, and overall stance for the specific sub-model.
A refurbished Navigator can look noticeably off if a 20-inch fitment is mixed up with a 22-inch one. Buyers concerned with authenticity of appearance should confirm the original wheel package for the exact trim, then compare the current setup against that baseline before replacing tires or refinishing wheels.
How does tire sizing affect the appearance of a 2020 Lincoln Trucks Navigator?
Tire sizing has a clear visual effect on the 2020 Lincoln Trucks Navigator because the model uses both 20-inch and 22-inch wheel fitments. A 275/55R20 presents a different sidewall proportion than a 285/45R22, even though both belong to the same vehicle family and keep overall dimensions fairly close.
That means appearance should be considered only after correct fitment is confirmed. Owners trying to maintain a stock-style look should match the tire size to the proper trim and wheel package. On vehicles with replacement wheels, the final visual result depends on wheel diameter, tire profile, and how the SUV sits at ride height.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2020 Lincoln Trucks Navigator?
Yes. Modifications can change how a tire fits on a 2020 Lincoln Trucks Navigator, even when the tire size itself seems close to stock. Aftermarket wheels, offset changes, suspension lowering or lifting, and body alterations can all affect clearance, steering travel, and how the tire sits within the wheel opening.
That is why the actual wheel and vehicle setup should be checked before replacement. A Base model converted to 22-inch wheels, for example, should be evaluated by its current hardware rather than by the original trim alone. Clearance at full lock and under suspension movement deserves attention before road use.
What should I inspect before driving a 2020 Lincoln Trucks Navigator on new tires?
Before putting miles on a 2020 Lincoln Trucks Navigator with new tires, inspect basic installation and condition items. Confirm that the tire size matches the wheel diameter, check inflation pressure, and make sure there is no visible damage such as cuts, bulges, or bead seating issues after mounting.
A short follow-up inspection is just as important once the vehicle has been driven. Recheck pressure, look for any signs of rubbing, and pay attention to steering feel or vibration. On a full-size SUV, it is also wise to confirm that the tires clear suspension and body components during turning and normal ride movement.
How often should tires on a 2020 Lincoln Trucks Navigator be inspected?
Tires on a 2020 Lincoln Trucks Navigator should be inspected regularly rather than only at replacement time. Routine checks should include inflation pressure, tread wear, visible cracking, cuts, bulges, and any uneven wear pattern that suggests an alignment, wheel, or suspension issue may be developing.
Vehicles that sit for long periods still deserve periodic inspection, since age and storage conditions can affect tire condition even with low mileage. It helps to look over the tires before longer drives, after impacts with potholes or curbs, and any time the ride or steering behavior changes from what feels normal.
