The 2014 Lincoln Trucks Navigator sits in the full-size luxury SUV category with the kind of body-on-frame presence, towing capability, and three-row utility that made the model a long-running choice for drivers who wanted premium comfort without giving up truck-based strength. Tire selection on this vehicle is tied first to wheel diameter, because the 2014 Lincoln Trucks Navigator uses two primary radial sizes: 255/70R18 and 275/55R20. Those two sizes reflect different wheel setups rather than a shift between bias-ply and radial construction. The real decision is confirming whether the vehicle is on 18-inch or 20-inch wheels, then choosing a tire that matches the intended balance of appearance, road use, and fitment.
Which Tire Size Is Right for The 2014 Lincoln Trucks Navigator
The 2014 Lincoln Trucks Navigator uses two primary tire sizes, and the correct one depends on wheel diameter rather than a change in construction, since both are radial fitments. Before choosing a tire, the first step is confirming whether the vehicle is equipped with 18-inch or 20-inch wheels. Both the Base and Navigator L can use either size, so wheel verification matters more than sub-model name.
255/70R18 is a metric radial size in which 255 identifies the section width in millimeters, 70 is the aspect ratio, R denotes radial construction, and 18 is the wheel diameter in inches. On the 2014 Lincoln Trucks Navigator, this size suits the 18-inch wheel setup and keeps tire selection within a modern radial format familiar to late-model SUV owners. For buyers comparing options, the key considerations are staying with the correct wheel diameter, matching the vehicle's intended use, and preserving proper clearance. It is the right size to evaluate when the Navigator is equipped with 18-inch wheels.
275/55R20 is also a metric radial size, with 275 describing section width in millimeters, 55 indicating the aspect ratio, R marking radial construction, and 20 showing the wheel diameter in inches. For the 2014 Lincoln Trucks Navigator, this size belongs to the 20-inch wheel configuration and gives the vehicle a different tire profile than the 18-inch setup. The practical choice here is less about construction and more about confirming the actual wheel package on the vehicle. This is the size to review when the Navigator is riding on 20-inch wheels rather than the 18-inch combination.
Tire fitment is straightforward across the covered 2014 Lincoln Trucks Navigator sub-models because both the Base and Navigator L use the same two radial tire sizes. The important detail is confirming which wheel diameter is on the vehicle, since either sub-model may be fitted with 18-inch or 20-inch wheels.

2014 Lincoln Trucks Navigator Base
The 2014 Lincoln Trucks Navigator Base can use either of the vehicle's two primary radial tire sizes, depending on whether it has 18-inch or 20-inch wheels. Tire selection starts with confirming the wheel setup, then choosing a tire that matches the vehicle's road use and overall fitment.
The 2014 Lincoln Trucks Navigator L follows the same fitment pattern, with both primary radial sizes used across this longer-wheelbase sub-model. The key step is checking the actual wheel diameter on the vehicle before selecting a tire, since the sub-model name alone does not narrow it to one size.
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 questions for the 2014 Lincoln Trucks Navigator usually center on which of the two radial sizes belongs on the vehicle, how wheel diameter affects fitment, and what to inspect before putting an SUV of this size back into regular road use.
Tire Size & Fitment
What tire size fits a 2014 Lincoln Trucks Navigator?
The 2014 Lincoln Trucks Navigator uses two primary tire sizes: 255/70R18 and 275/55R20. Both are radial sizes, and the correct choice depends on which wheel diameter is on the vehicle. That same two-size fitment pattern applies across the covered Navigator Base and Navigator L sub-models.
The most important step is checking the actual wheel setup before choosing a tire. An 18-inch wheel takes 255/70R18, while a 20-inch wheel takes 275/55R20. If the vehicle has had wheel changes at some point, confirm the wheel diameter directly rather than assuming the tire size from the sub-model name.
What size rim does a 2014 Lincoln Trucks Navigator use?
A 2014 Lincoln Trucks Navigator uses either an 18-inch or 20-inch rim, depending on the wheel package on the vehicle. The 255/70R18 tire corresponds to the 18-inch setup, and the 275/55R20 tire corresponds to the 20-inch setup. Both sizes are radial fitments.
Rim diameter should be confirmed before any tire purchase because the two sizes are not interchangeable across different wheel diameters. Reading the size on the current tire or measuring the wheel is the quickest check. That matters even more on vehicles that may have seen replacement wheels or previous owner modifications.
Do all 2014 Lincoln Trucks Navigator sub-models use the same tire size?
The covered 2014 Lincoln Trucks Navigator sub-models share the same fitment pattern rather than one single tire size. Both the Navigator Base and Navigator L can use 255/70R18 or 275/55R20, with the final choice determined by wheel diameter. Both sizes are radial tires.
That means the sub-model name alone does not settle the fitment question. A Base or L model may be on either wheel setup, so it is smarter to verify the actual wheels on the vehicle first. Once that is confirmed, tire selection becomes a matter of choosing the right tire within the correct size.
Choosing the Right Tire
What should I consider when choosing a 255/70R18 tire for a 2014 Lincoln Trucks Navigator?
A 255/70R18 tire is the correct size for a 2014 Lincoln Trucks Navigator equipped with 18-inch wheels. The first consideration is confirming that the vehicle actually uses that wheel diameter. After that, focus on selecting a tire that matches the Navigator's size, weight, and intended use as a full-size luxury SUV.
Daily road driving, seasonal use, towing demands, and ride preference can all shape the final choice within that size. It also helps to inspect the current wheel width and overall vehicle setup before replacing tires, especially if the Navigator has had suspension work, aftermarket wheels, or other changes that could influence clearance.
What should I consider when choosing a 275/55R20 tire for a 2014 Lincoln Trucks Navigator?
A 275/55R20 tire belongs on a 2014 Lincoln Trucks Navigator that has 20-inch wheels. Since this is one of two primary factory-type size paths for the model, the first job is confirming the wheel diameter rather than selecting by sub-model alone. From there, the choice is about finding the right tire within the correct metric radial size.
Owners often compare ride character, intended mileage, and how the tire complements the vehicle's wheel package before making a selection. It is also worth checking the current tires for uneven wear, because that can point to alignment or suspension issues. Replacing tires without addressing those conditions can shorten tire life and affect road manners.
How do I choose between the available tire sizes for a 2014 Lincoln Trucks Navigator?
Choosing between the available tire sizes for a 2014 Lincoln Trucks Navigator is not a matter of preference alone, because each size is tied to a different wheel diameter. The vehicle uses either 255/70R18 on 18-inch wheels or 275/55R20 on 20-inch wheels. Both the Base and Navigator L can use either setup.
The practical approach is to verify the wheel size already on the vehicle and stay within that fitment unless the wheel package itself is being changed. If the Navigator has aftermarket wheels, confirm the actual dimensions carefully. Tire selection should follow the wheel, not the other way around, on a large SUV like this.
Restoration & Appearance
Does correct tire fitment matter for a 2014 Lincoln Trucks Navigator restoration?
Correct tire fitment still matters on a 2014 Lincoln Trucks Navigator, even though it is newer than traditional collector-era vehicles. Using the proper 255/70R18 or 275/55R20 size for the wheel setup helps preserve the vehicle's intended stance and keeps the overall presentation aligned with the original style of the SUV.
A restoration-minded owner should start by confirming whether the vehicle retains its original wheel diameter or has been changed over time. Tire choice can affect how finished the vehicle looks once the body and trim are sorted. When exact visual authenticity matters, compare the current wheel-and-tire package against vehicle-specific reference material before making changes.
How does tire size affect the appearance of a restored 2014 Lincoln Trucks Navigator?
Tire size has a noticeable effect on the appearance of a restored 2014 Lincoln Trucks Navigator because the two approved sizes pair with different wheel diameters. A 255/70R18 and a 275/55R20 both belong to the vehicle, but they create different visual proportions between sidewall height and wheel presence.
That makes wheel confirmation important for owners trying to preserve a stock-style look instead of simply replacing worn tires. A change in wheel diameter can alter the vehicle's visual balance even when the tire remains serviceable. Matching the tire size to the correct wheel package is the cleanest way to keep the Navigator looking properly sorted.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2014 Lincoln Trucks Navigator?
Yes, modifications can affect tire fitment on a 2014 Lincoln Trucks Navigator. Wheel changes, altered offset, suspension lowering or lifting, and body modifications can all influence how a 255/70R18 or 275/55R20 tire sits in the wheel opening. Even when the nominal tire size stays the same, clearance can change.
That is why a modified Navigator should be checked at full steering lock and through normal suspension travel before settling on replacement tires. Pay attention to inner clearance, fender clearance, and any signs of rubbing on the current setup. Those checks matter more than the sub-model badge when the vehicle no longer has its original configuration.
What should I inspect before driving a 2014 Lincoln Trucks Navigator on new tires?
Before driving a 2014 Lincoln Trucks Navigator on new tires, inspect the wheels for damage, verify that the wheel diameter matches the intended tire size, and make sure the tires are properly mounted and inflated. It also helps to check alignment, especially if the old tires showed uneven tread wear or shoulder wear.
A full-size SUV places meaningful demands on its tires, so suspension and steering condition should not be overlooked. Worn shocks, loose steering parts, or neglected brakes can affect how new tires behave on the road. A short test drive followed by a second visual check for clearance issues and proper seating is a sensible final step.
How often should tires on a 2014 Lincoln Trucks Navigator be inspected?
Tires on a 2014 Lincoln Trucks Navigator should be inspected regularly, not just when tread looks low. Pressure, tread wear pattern, cuts, punctures, bulges, and sidewall damage are all worth checking, especially on a vehicle this size. The inspection should also confirm that the installed tire size matches the wheel diameter on the SUV.
Monthly checks are a practical habit, with closer attention before road trips or after the vehicle has been sitting for extended periods. A luxury SUV that sees occasional use can still develop air loss or age-related issues. Catching those problems early helps protect ride quality, handling, and the service life of the replacement tires.
