The 2020 Lincoln Trucks Aviator sits in the modern luxury SUV class with a strong emphasis on quiet road manners, upscale design, and confident long-distance comfort. For owners, tire selection is less about vintage-style construction and more about matching the exact wheel and trim configuration already on the vehicle. This model uses radial fitments in four sizes: 255/60R19, 255/55R20, 275/45R21, and 275/40R22. That creates meaningful differences in wheel diameter, tire profile, and sub-model fitment. The right choice starts with confirming the exact sub-model and wheel setup, especially on Reserve, Black Label, and Grand Touring Plug-In Hybrid versions.
Which Tire Size Is Right for The 2020 Lincoln Trucks Aviator
The 2020 Lincoln Trucks Aviator uses four primary tire sizes, and the correct one depends on the exact sub-model and wheel diameter. These are all radial fitments, but they span 19-inch, 20-inch, 21-inch, and 22-inch rims, so the first step is confirming the actual wheel setup on the vehicle before comparing tire choices.
255/60R19 is a modern metric radial size in which 255 represents section width in millimeters, 60 is the aspect ratio, R identifies radial construction, and 19 is the rim diameter in inches. On the 2020 Lincoln Trucks Aviator, this size serves a specific sub-model configuration rather than the full model range. Its proportions deliver a taller sidewall than the larger-wheel Aviator fitments, which can matter when maintaining the intended wheel-and-tire relationship. Use this size only after confirming that the vehicle is equipped with the matching 19-inch wheel setup.
Fit(s): Black Label, Reserve (AWD), and Reserve (RWD)
Construction: Radial|Rim: 22 in
275/40R22 is a modern metric radial size with a 275-millimeter nominal section width, a 40-series profile, and a 22-inch rim diameter. On the 2020 Lincoln Trucks Aviator, it belongs to specific upper-trim configurations that use a larger wheel package. Compared with the other Aviator sizes, this fitment combines a wider tread section with a lower-profile sidewall, making wheel confirmation especially important before replacement. It is the right choice only for Aviators already set up with the corresponding 22-inch wheels and the sub-models that use them.
Fit(s): Black Label Grand Touring Plug-In Hybrid and Grand Touring Plug-In Hybrid
Construction: Radial|Rim: 21 in
275/45R21 is a modern metric radial size where 275 indicates nominal section width in millimeters, 45 is the aspect ratio, and 21 identifies the wheel diameter in inches. This size appears on Grand Touring Plug-In Hybrid-related Aviator configurations, so it should not be treated as a universal fitment across the model line. Its combination of width and 21-inch rim diameter places it between the 20-inch and 22-inch setups in overall presentation. Buyers should confirm both sub-model and wheel diameter before choosing this size for replacement.
Fit(s): Grand Touring Plug-In Hybrid, Reserve (AWD), and Reserve (RWD)
Construction: Radial|Rim: 20 in
255/55R20 is a modern metric radial size with a 255-millimeter nominal section width, a 55-series profile, and a 20-inch rim diameter. On the 2020 Lincoln Trucks Aviator, it is used across several sub-models, including certain Grand Touring Plug-In Hybrid and Reserve configurations. That broader application makes it a common fitment within the range, but it still depends on the vehicle wearing the proper 20-inch wheels. It is the size to evaluate when the Aviator has a 20-inch factory-style wheel setup rather than the 19-inch, 21-inch, or 22-inch alternatives.
Tire fitment varies across the 2020 Lincoln Trucks Aviator lineup, and several sub-models use more than one wheel-and-tire package. Checking the exact trim and the wheel diameter already on the vehicle is the key step before choosing a replacement tire.

2020 Lincoln Trucks Aviator Base
The 2020 Lincoln Trucks Aviator Base uses a single radial tire fitment, making replacement more straightforward than on trims with optional wheel packages. The practical job is confirming that the vehicle still has its 19-inch wheel setup before selecting a matching tire.
The 2020 Lincoln Trucks Aviator Black Label uses a dedicated radial fitment tied to its larger wheel package. That makes wheel-diameter confirmation especially important, since moving to the correct replacement size depends on matching the existing 22-inch setup.
2020 Lincoln Trucks Aviator Black Label Grand Touring Plug-In Hybrid
The 2020 Lincoln Trucks Aviator Black Label Grand Touring Plug-In Hybrid uses a single radial size associated with its 21-inch wheel package. Tire selection is mainly about confirming that exact configuration and staying with the proper size for the vehicle's present wheel setup.
2020 Lincoln Trucks Aviator Grand Touring Plug-In Hybrid
The 2020 Lincoln Trucks Aviator Grand Touring Plug-In Hybrid can use more than one radial tire size, so identifying the exact wheel package comes before comparing replacement options. The key distinction is whether the vehicle is on the 20-inch or 21-inch setup.
The 2020 Lincoln Trucks Aviator Reserve (AWD) uses one of two radial tire sizes depending on the wheel package installed on the vehicle. Replacement starts with confirming whether the Aviator is wearing 20-inch or 22-inch wheels rather than choosing by trim name alone.
The 2020 Lincoln Trucks Aviator Reserve (RWD) also uses two possible radial tire sizes, each tied to a different wheel diameter. The most important step is matching the tire to the actual 20-inch or 22-inch wheel setup currently on the vehicle.
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
A 2020 Lincoln Trucks Aviator raises practical tire questions about trim-specific sizing, wheel diameter, and choosing among the 19-inch, 20-inch, 21-inch, and 22-inch radial fitments. These FAQs focus on exact size selection, wheel confirmation, replacement planning, and road-use checks.
Tire Size & Fitment
What tire size fits a 2020 Lincoln Trucks Aviator?
The 2020 Lincoln Trucks Aviator uses four primary tire sizes: 255/60R19, 255/55R20, 275/45R21, and 275/40R22. All of them are radial sizes, but they do not apply across the entire model line, because fitment changes by sub-model and wheel package.
The most important step is confirming the exact trim and the wheel diameter on the vehicle before choosing a replacement tire. A Base model, a Black Label, and a Grand Touring Plug-In Hybrid can use different sizes, and Reserve models can use more than one setup depending on the wheels installed.
What size rim does a 2020 Lincoln Trucks Aviator use?
A 2020 Lincoln Trucks Aviator can use 19-inch, 20-inch, 21-inch, or 22-inch rims depending on the sub-model and wheel package. Those rim diameters correspond to the four primary tire sizes used across the Aviator lineup.
That wide range means rim diameter should be verified before any tire purchase, even when the trim name seems familiar. Looking at the existing sidewall size and physically confirming the wheel diameter helps prevent ordering a 20-inch tire for an Aviator equipped with 21-inch or 22-inch wheels.
Why does the 2020 Lincoln Trucks Aviator have more than one tire size?
The 2020 Lincoln Trucks Aviator has more than one tire size because different sub-models use different wheel packages. Base, Black Label, Grand Touring Plug-In Hybrid, and Reserve configurations are not all equipped with the same rim diameter, so their tire sizes differ as well.
That means tire selection starts with identifying the exact version of the Aviator and confirming the wheels that are actually on it today. A Reserve model, for example, can use either a 20-inch or 22-inch fitment, so the trim badge alone is not always enough to choose the right tire.
Choosing the Right Tire
What should I consider when choosing a tire for a 2020 Lincoln Trucks Aviator?
Start with the correct size for the exact 2020 Lincoln Trucks Aviator sub-model and wheel package. The main fitments are 255/60R19, 255/55R20, 275/45R21, and 275/40R22, so replacement choice begins with matching the existing wheel diameter and the intended trim-specific setup.
After that, compare the tire's size format, sidewall profile, and whether the vehicle is being kept in its present wheel configuration. It also helps to inspect the current tires and wheels for previous changes, since an Aviator with aftermarket wheels or a non-original package should be matched by actual measurements, not assumption.
How do I choose between the available 255/55R20 and 275/40R22 tires for a 2020 Lincoln Trucks Aviator Reserve?
A 2020 Lincoln Trucks Aviator Reserve can use either 255/55R20 or 275/40R22, depending on the wheel package installed on the vehicle. The correct choice is not a matter of preference alone, because each size is built around a different rim diameter.
Selection becomes simple once the wheel size is confirmed. A Reserve with 20-inch wheels needs the 255/55R20 fitment, while a Reserve with 22-inch wheels needs the 275/40R22 fitment. Checking the sidewall on the current tires and measuring the wheel setup is the safest way to avoid crossing those two packages.
How do I choose between the available tire sizes for a 2020 Lincoln Trucks Aviator Grand Touring Plug-In Hybrid?
The 2020 Lincoln Trucks Aviator Grand Touring Plug-In Hybrid can use either 255/55R20 or 275/45R21, depending on the wheel package. Both are radial fitments, but they are tied to different rim diameters, so the right replacement depends on the wheels currently on the vehicle.
Choosing between them starts with confirming whether the Aviator has 20-inch or 21-inch wheels rather than comparing the numbers in isolation. That check matters because section width, profile, and wheel diameter all change together, and using the wrong size can create immediate fitment and clearance issues.
Restoration & Appearance
Does correct tire fitment matter for a 2020 Lincoln Trucks Aviator restoration?
Correct tire fitment still matters on a 2020 Lincoln Trucks Aviator, even though it is a modern luxury SUV rather than a vintage restoration vehicle. The right tire size preserves the intended relationship between the wheel package, body proportions, and the overall stance of the specific trim.
Owners returning an Aviator to stock-style appearance should verify the original wheel diameter used on that exact sub-model before replacing tires. Since this model used 19-inch, 20-inch, 21-inch, and 22-inch fitments across the range, appearance and fitment can change noticeably if the replacement size does not match the vehicle's actual setup.
How does tire size affect the appearance of a 2020 Lincoln Trucks Aviator?
Tire size has a visible effect on a 2020 Lincoln Trucks Aviator because the model uses several wheel diameters and sidewall profiles. A 255/60R19 setup presents more sidewall than a 275/40R22 setup, while the 20-inch and 21-inch packages fall between those two visual extremes.
That means appearance-conscious owners should choose the size that matches the wheel package already on the vehicle, especially when preserving a stock-style look. Changing to a different size without changing wheels correctly can alter the SUV's proportions and create a result that looks out of place even before fitment problems appear.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2020 Lincoln Trucks Aviator?
Yes, modifications can affect tire fitment on a 2020 Lincoln Trucks Aviator. Aftermarket wheels, suspension changes, ride-height adjustments, or body modifications can all change the space available for a tire, even when the size sounds close to one of the original Aviator fitments.
A modified vehicle should be checked by actual wheel diameter, width, and clearance at full steering lock and suspension travel before replacement tires are chosen. That matters even more on Aviator trims that already use larger 21-inch or 22-inch combinations, where small setup changes can have a bigger effect on fitment.
What should I inspect before driving a 2020 Lincoln Trucks Aviator on new tires?
Before driving a 2020 Lincoln Trucks Aviator on new tires, inspect the wheel size, tire pressure, valve stems, and overall tire condition after installation. It is also wise to confirm that the new tires match the correct size for the sub-model and that there is no visible interference with suspension or body components.
A short, careful road test can help verify that the vehicle tracks normally and that no rubbing appears during turning or over bumps. On an Aviator with an optional wheel package or a previous wheel change, rechecking lug torque and looking for even clearance at all four corners is a smart final step.
What should I check before a longer drive in a 2020 Lincoln Trucks Aviator?
Before a longer drive in a 2020 Lincoln Trucks Aviator, check tire pressure, tread condition, sidewall condition, and any signs of cuts, bulges, or irregular wear. A longer trip is also a good reason to confirm that the vehicle is riding on the correct tire size for its wheel package.
Long-distance confidence improves when the wheels and tires are matched correctly and the suspension is in sound condition. It also helps to inspect for slow air loss and confirm that the spare or roadside plan matches the wheel-and-tire setup, since Aviators can use several different rim diameters across the model range.
