The 2015 Lincoln Trucks Navigator comes from the final years of the full-size, body-on-frame Navigator before Lincoln moved the model into a new generation. Buyers are often drawn to this SUV for its combination of traditional American luxury, three-row usefulness, and substantial road presence. Tire selection centers on two radial fitments, 275/55R20 and 285/45R22, so the first step is confirming which wheel diameter is on the vehicle. Because both the Base and Navigator L can use either size, the real choice usually comes down to wheel setup, tire profile, and how the vehicle is being kept for daily use, clean original-style presentation, or upgraded appearance.
Which Tire Size Is Right for The 2015 Lincoln Trucks Navigator
The 2015 Lincoln Trucks Navigator uses two primary tire sizes, and the key difference is wheel diameter rather than sub-model. Both the Base and Navigator L can use either 275/55R20 or 285/45R22, so confirming whether the vehicle has 20-inch or 22-inch wheels comes first. Once that is settled, the decision shifts to selecting the right radial tire for the wheel and the look you want to maintain.
A 275/55R20 tire uses a 275-millimeter nominal section width, a 55-series aspect ratio, radial construction, and a 20-inch rim. On the 2015 Lincoln Trucks Navigator, this is one of the standard modern radial fitments and suits vehicles running the 20-inch wheel setup. This size generally preserves the full-size SUV character of the Navigator while keeping the tire and wheel package in the intended modern metric format. It is the size to evaluate when the vehicle still has its 20-inch wheels or when returning a modified truck to the correct rim diameter for this fitment.
A 285/45R22 tire uses a 285-millimeter nominal section width, a 45-series aspect ratio, radial construction, and a 22-inch rim. For the 2015 Lincoln Trucks Navigator, this size belongs to the 22-inch wheel configuration and gives the vehicle a distinctly larger-wheel presentation. The shorter sidewall changes the visual balance compared with the 20-inch setup, even though it remains a proper modern metric radial fitment. This is the size to focus on when the Navigator is already equipped with 22-inch wheels and the goal is to keep that wheel diameter and tire profile combination in place.
Tire fitment is straightforward across the covered 2015 Lincoln Trucks Navigator sub-models because both the Base and Navigator L use the same two size options. The important step is not trim identification by itself, but confirming whether the vehicle is on 20-inch or 22-inch wheels before choosing tires.

2015 Lincoln Trucks Navigator Base
The 2015 Lincoln Trucks Navigator Base can use either of the model's two radial tire sizes, depending on which wheel diameter is on the vehicle. Tire selection usually comes down to confirming the existing 20-inch or 22-inch setup and then choosing the tire profile that matches that wheel package.
The 2015 Lincoln Trucks Navigator L shares the same two radial tire size options as the standard-wheelbase model. That makes wheel confirmation the real fitment step, followed by choosing a tire that matches the installed rim diameter and the vehicle's current appearance and use.
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 tire questions for the 2015 Lincoln Trucks Navigator usually center on choosing between the 20-inch and 22-inch fitments, understanding modern metric radial sizing, and checking wheel, clearance, and maintenance details before putting the vehicle back into regular road use.
Tire Size & Fitment
What tire size fits a 2015 Lincoln Trucks Navigator?
The 2015 Lincoln Trucks Navigator uses two primary tire sizes: 275/55R20 and 285/45R22. Both are radial metric sizes, and both the Navigator Base and Navigator L can use either one depending on the wheel package installed on the vehicle.
The important thing to confirm is the actual wheel diameter on the SUV before ordering tires. A 20-inch wheel requires 275/55R20, while a 22-inch wheel requires 285/45R22. If the Navigator has been changed from its original wheel setup, verify the current rim size on the vehicle rather than assuming the tire size from the sub-model name alone.
What size rim does a 2015 Lincoln Trucks Navigator use?
A 2015 Lincoln Trucks Navigator uses either a 20-inch rim or a 22-inch rim, depending on which tire size is on the vehicle. The 275/55R20 fitment uses a 20-inch wheel, and the 285/45R22 fitment uses a 22-inch wheel.
Checking the wheel diameter is the first step because these two tire sizes are not interchangeable across different rim diameters. Looking at the tire sidewall or measuring the wheel helps confirm what is actually installed. That matters even more on a used Navigator, where previous owners may have changed the factory-style wheel and tire package.
Do all 2015 Lincoln Trucks Navigator sub-models use the same tire size?
The 2015 Lincoln Trucks Navigator Base and the 2015 Lincoln Trucks Navigator L share the same two tire size options: 275/55R20 and 285/45R22. In that sense, sub-model fitment stays consistent across both versions of the vehicle.
That consistency does not remove the need to inspect the actual wheel setup on the SUV. One Navigator may be on 20-inch wheels while another uses 22-inch wheels, even within the same sub-model. The safest approach is to identify the installed wheel diameter and then match the tire size to that wheel rather than choosing by trim alone.
Choosing the Right Tire
What should I consider when choosing a tire for a 2015 Lincoln Trucks Navigator?
Start with the correct primary size for the wheel on the vehicle: 275/55R20 for a 20-inch rim or 285/45R22 for a 22-inch rim. Because both are radial metric fitments used on the 2015 Lincoln Trucks Navigator, the real selection point is matching the tire to the wheel diameter already in place.
After size, look at how the Navigator is used and presented. A vehicle kept close to its original-style luxury SUV appearance may stay with its current wheel package, while one with an upgraded visual stance may already be set up around 22-inch wheels. It also helps to inspect overall tire condition, even wear, and any signs of suspension or alignment issues before replacing the set.
How do I choose between the available 2015 Lincoln Trucks Navigator tire sizes?
Choosing between 275/55R20 and 285/45R22 is really a matter of wheel diameter, not preference alone. The 2015 Lincoln Trucks Navigator uses 275/55R20 on 20-inch wheels and 285/45R22 on 22-inch wheels, so the wheel already on the vehicle determines which primary size applies.
The practical difference is that each size belongs to a different wheel-and-tire package. If the Navigator still has its original-style setup, matching the installed wheel diameter usually keeps the process simple. On a modified truck, check the current wheels carefully and make sure there is still proper clearance at the fenders and steering range before settling on the replacement size.
What does 275/55R20 mean on a 2015 Lincoln Trucks Navigator?
On a 2015 Lincoln Trucks Navigator, 275/55R20 means the tire has a 275-millimeter nominal section width, a 55-series aspect ratio, radial construction, and a 20-inch rim diameter. It is a modern metric radial size, which is the standard sizing format for this vehicle.
Understanding that code helps prevent mismatching tires to wheels. The final number, 20, is the wheel diameter and must match the rim exactly. The width and profile are also part of the vehicle's intended tire package, so changing them without checking the full setup can affect clearance, appearance, and the way the Navigator sits on its wheels.
Restoration & Appearance
Which tire should I choose for a period-style 2015 Lincoln Trucks Navigator?
A period-style choice for a 2015 Lincoln Trucks Navigator usually means staying with the wheel diameter and tire size that matches the vehicle's established factory-era presentation. That points to either 275/55R20 or 285/45R22, depending on whether the SUV is equipped with 20-inch or 22-inch wheels.
Keeping the existing wheel-and-tire format often preserves the Navigator's intended visual balance better than changing sizes casually. For an owner focused on originality, the next step is comparing the current setup with window-sticker records, original sales material, or marque-specific documentation. That approach is more reliable than choosing a tire strictly by appearance or assuming all Navigators left the factory the same way.
Does correct tire fitment matter for a 2015 Lincoln Trucks Navigator restoration?
Correct tire fitment matters on a 2015 Lincoln Trucks Navigator because the wrong size can change the vehicle's stance, wheel-to-tire proportion, and overall presentation. Since this model uses either 275/55R20 or 285/45R22, matching the tire to the actual wheel package is part of preserving an authentic-looking result.
Appearance is only one reason to stay disciplined about size. Proper fitment also helps avoid avoidable clearance and setup problems that can distract from an otherwise clean restoration or refurbishment. Even on a newer collector-oriented SUV, confirming the wheel diameter, checking for prior modifications, and keeping a matched set are all part of a more convincing finished vehicle.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2015 Lincoln Trucks Navigator?
Yes, modifications can affect tire fitment on a 2015 Lincoln Trucks Navigator. Wheel changes, suspension alterations, ride-height adjustments, or body modifications can all change how a 275/55R20 or 285/45R22 tire sits in the wheel opening and how much room it has during steering and suspension movement.
A used Navigator may already have aftermarket wheels or altered suspension, so it is worth checking more than just the size printed on the sidewall. Measure the actual wheel diameter, inspect for rubbing marks, and look at inner-fender and steering clearance before replacing tires. That extra step helps prevent choosing the correct nominal size for a setup that has changed in important ways.
What should I inspect before driving a 2015 Lincoln Trucks Navigator on new tires?
Before driving a 2015 Lincoln Trucks Navigator on new tires, inspect the wheels for damage, verify that all four tires match the intended size, and make sure inflation is set correctly for the vehicle's use. It is also smart to check for uneven wear patterns that may point to alignment or suspension issues.
A careful walkaround should include looking for sidewall damage, cuts, and any signs that the old tires had clearance problems. The Navigator's size and weight make steering, braking, and suspension condition especially important, so worn components should not be ignored when new tires go on. A short, low-speed test drive can confirm that the vehicle tracks cleanly and turns without rubbing.
How often should tires on a 2015 Lincoln Trucks Navigator be inspected?
Tires on a 2015 Lincoln Trucks Navigator should be inspected regularly, not only at replacement time. A monthly visual check is a sensible routine for a full-size SUV, especially one that may alternate between daily use and longer periods of sitting.
Look for pressure loss, uneven tread wear, cuts, bulges, and weather cracking, and check that the tire size still matches the wheel package on the vehicle. If the Navigator is stored for stretches, inspect the tires again before returning it to highway use. Catching age- or condition-related problems early is especially important on a heavy luxury SUV that depends on stable tire condition.
