The 2018 Lincoln Trucks Navigator marked a major step forward for Lincoln’s full-size luxury SUV, pairing modern design and upscale road manners with the size and presence buyers expect from a premium three-row vehicle. For tire selection, that means the first decision is identifying the exact Navigator sub-model, because this model year uses either 275/55R20 or 285/45R22 radial tires. Both are modern metric radial sizes, but they are tied to different wheel diameters and trim configurations. Choosing the right tire starts with confirming whether the vehicle is on its original 20-inch or 22-inch setup, then narrowing by intended use, ride priorities, and any wheel changes made since new.
Which Tire Size Is Right for The 2018 Lincoln Trucks Navigator
Two tire sizes apply to the 2018 Lincoln Trucks Navigator, and the correct one depends on the specific sub-model and wheel diameter. The key first step is confirming whether the vehicle uses a 20-inch or 22-inch rim, since the Navigator does not use one universal tire size across all trims. Once that is clear, the decision becomes choosing the right radial tire within the proper size for the vehicle’s current wheel setup and intended road use.
Fit(s): Black Label, L Black Label, L Reserve, L Select, Reserve, and Select
Construction: Radial|Rim: 22 in
285/45R22 is a modern metric radial size in which 285 identifies the section width in millimeters, 45 is the aspect ratio, R indicates radial construction, and 22 is the wheel diameter in inches. On the 2018 Lincoln Trucks Navigator, this size is tied to 22-inch wheel applications and is used across several sub-models. Its overall dimensions are close to the alternate 20-inch fitment, but the wheel diameter is different, so the tire choice must match the actual rim on the vehicle. This size is the right place to focus if the Navigator carries its larger factory-style wheel package or an equivalent 22-inch setup.
275/55R20 is also a modern metric radial size, with 275 representing section width in millimeters, 55 showing the aspect ratio, R for radial construction, and 20 for the wheel diameter. On the 2018 Lincoln Trucks Navigator, this size is associated with the 20-inch wheel application rather than the larger 22-inch package. Even though its overall diameter is close to the 22-inch fitment, it should be chosen only for a Navigator equipped with the correct 20-inch rims. This size is the one to evaluate if the vehicle remains on its original 20-inch wheel arrangement or has been returned to that configuration.
Sub-model fitment matters on the 2018 Lincoln Trucks Navigator because tire size changes with trim and wheel package. Most covered sub-models use the 22-inch setup, while the Premiere uses the 20-inch size, so confirming the exact trim and wheel diameter prevents choosing the wrong tire.

Frequently Asked Questions
Common 2018 Lincoln Trucks Navigator tire questions usually come down to trim-specific size selection, 20-inch versus 22-inch rim fitment, and what to inspect before putting a large luxury SUV back on the road.
Tire Size & Fitment
What tire size fits a 2018 Lincoln Trucks Navigator?
The 2018 Lincoln Trucks Navigator uses either 285/45R22 or 275/55R20, depending on the sub-model. Most covered sub-models use 285/45R22, while the Navigator Premiere uses 275/55R20. Both are radial tire sizes, but they are tied to different wheel diameters and should not be treated as one interchangeable fitment.
The most important step is confirming the exact trim level and the actual wheels currently on the vehicle. A used Navigator may have had wheels changed, so checking the tire sidewall and measuring rim diameter before replacement helps avoid ordering a 20-inch tire for a 22-inch wheel, or the reverse.
What size rim does a 2018 Lincoln Trucks Navigator use?
A 2018 Lincoln Trucks Navigator uses either a 20-inch or 22-inch rim, depending on sub-model. The 275/55R20 tire fits the 20-inch application, while the 285/45R22 tire fits the 22-inch application. Rim diameter is built into the tire size itself, so matching that final number is essential.
Checking wheel diameter should come before comparing tire brands or tread patterns. Even though the two Navigator tire sizes have similar overall dimensions, the wheel size is different, and a 20-inch tire cannot mount on a 22-inch wheel. If the SUV has aftermarket wheels, confirm both diameter and width before selecting tires.
Do all 2018 Lincoln Trucks Navigator sub-models use the same tire size?
No, the 2018 Lincoln Trucks Navigator does not use one tire size across every sub-model. Black Label, L Black Label, L Reserve, L Select, Reserve, and Select use 285/45R22, while the Premiere uses 275/55R20. That makes the exact sub-model an important part of getting the fitment right.
Trim identification matters because the two sizes correspond to different wheel diameters, not just different tire proportions. Before replacing a full set or a single damaged tire, verify the trim badge, read the current tire sidewall, and confirm the wheel size on the vehicle so the replacement matches the actual setup in service.
Choosing the Right Tire
What should I consider when choosing a 285/45R22 tire for a 2018 Lincoln Trucks Navigator?
Start by confirming that the 2018 Lincoln Trucks Navigator actually uses the 285/45R22 size, since that fitment applies to several sub-models but not all of them. The key factors are correct size, matching 22-inch wheel diameter, and choosing a tire intended for the weight and road use of a full-size luxury SUV.
A careful choice also means looking at the vehicle’s current condition and setup. Tire wear patterns can point to alignment or suspension issues, and any wheel change from the original 22-inch arrangement should be checked before mounting replacements. Keeping all four tires in the proper size helps preserve ride quality, handling balance, and appearance.
What should I consider when choosing a 275/55R20 tire for a 2018 Lincoln Trucks Navigator?
The 275/55R20 size belongs to the 2018 Lincoln Trucks Navigator Premiere, so the first step is making sure the vehicle still uses its 20-inch wheel setup. After that, selection comes down to staying with the correct size and choosing a radial tire that suits a large SUV’s combination of comfort, load-carrying needs, and everyday road use.
It also helps to inspect the current tires and wheels before replacing them. Uneven tread wear, impact damage, or prior wheel substitutions can change what needs attention first. Matching the proper 20-inch fitment across the axle and confirming wheel condition before mounting new tires keeps the replacement process straightforward.
How do I choose between the available tire sizes for a 2018 Lincoln Trucks Navigator?
Choosing between 285/45R22 and 275/55R20 is not a matter of preference alone on a 2018 Lincoln Trucks Navigator. The right size depends on the sub-model and, more importantly, the wheel diameter currently on the vehicle. Each tire size is built for a different rim, so the wheel setup determines the correct starting point.
The simplest approach is to confirm the trim, then verify the tire size printed on the sidewall and the actual wheel diameter. If the Navigator has been modified or fitted with replacement wheels, rely on the wheel and tire installed rather than assuming the original trim still tells the whole story.
Restoration & Appearance
Does correct tire fitment matter for a 2018 Lincoln Trucks Navigator restoration or refurbishment?
Yes, correct tire fitment still matters on a 2018 Lincoln Trucks Navigator even though it is a modern luxury SUV rather than a vintage restoration project. Using the proper 275/55R20 or 285/45R22 size helps preserve the intended stance, wheel-to-tire proportion, and overall presentation of the vehicle.
A refurbishment-focused owner should confirm whether the Navigator remains on its original wheel package before buying tires. Returning the vehicle to a clean, stock-style appearance usually starts with the right wheel diameter and matching tire size, especially on trims where the visual difference between the 20-inch and 22-inch setups is significant.
How does tire size affect the appearance of a 2018 Lincoln Trucks Navigator?
Tire size has a noticeable effect on the appearance of a 2018 Lincoln Trucks Navigator because the vehicle uses either a 20-inch or 22-inch wheel setup depending on sub-model. The 285/45R22 fitment presents a larger wheel package visually, while the 275/55R20 maintains the look associated with the 20-inch application.
Appearance choices should still stay grounded in proper fitment. Installing tires that do not match the wheel diameter or intended setup can disrupt the SUV’s proportions and create avoidable fitment issues. For a stock-style presentation, confirm the exact trim and current wheels before deciding which size belongs on the vehicle.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2018 Lincoln Trucks Navigator?
Yes, modifications can affect tire fitment on a 2018 Lincoln Trucks Navigator. Aftermarket wheels, suspension changes, leveling or lowering kits, and body alterations can all change the space available around a 275/55R20 or 285/45R22 tire. Even when the sidewall size stays the same, wheel width or offset changes may alter clearance.
That makes it smart to inspect the actual setup before ordering replacements. Check wheel diameter, wheel width, and the tire’s position relative to suspension parts, fender edges, and steering travel. On a large SUV, small changes in offset or ride height can matter, especially when replacing tires after prior modifications.
What should I inspect before driving a 2018 Lincoln Trucks Navigator on new tires?
Before driving a 2018 Lincoln Trucks Navigator on new tires, inspect wheel condition, valve stems, lug hardware, and the overall match between tire size and wheel diameter. It is also wise to check alignment, since uneven wear on the old tires may point to suspension or steering issues that could shorten the life of the replacements.
A road-ready inspection should also include tire pressure, sidewall condition, and full steering clearance once the new tires are mounted. After a short initial drive, recheck pressures and look for any signs of rubbing or vibration. Catching those issues early helps protect both the tires and the vehicle’s ride quality.
How often should tires on a 2018 Lincoln Trucks Navigator be inspected?
Tires on a 2018 Lincoln Trucks Navigator should be inspected regularly, not just when replacement time arrives. Routine checks for tread wear, cuts, punctures, sidewall damage, and air pressure are especially important on a heavy luxury SUV, where tire condition has a direct effect on ride quality, braking feel, and everyday road confidence.
A practical habit is to inspect them monthly and again before longer trips. It also helps to look more closely after pothole impacts or curb contact, especially on 22-inch wheel applications. Consistent inspections make it easier to catch irregular wear, pressure loss, or wheel damage before those problems become more expensive.
