The 1999 Lincoln Trucks Navigator arrived during the rise of the full-size luxury SUV, combining truck-based capability with upscale road manners and premium presence. For owners today, tire choice plays a big role in preserving that balance between everyday drivability and the Navigator’s original stance. This model uses radial tire fitments in two sizes, 245/75R16 and 255/75R17, with fitment varying by drivetrain and wheel setup. That makes the key decision less about vintage construction and more about confirming the correct rim diameter, then choosing the right tread and sidewall presentation. A careful match matters most on a used or modified SUV where wheel changes may have happened over time.
Which Tire Size Is Right for The 1999 Lincoln Trucks Navigator
The 1999 Lincoln Trucks Navigator uses two primary tire sizes, and the correct one depends on sub-model and wheel diameter. Both are radial metric sizes, but they do not share the same rim size, so the first step is confirming whether the vehicle is on a 16-inch or 17-inch wheel before comparing tire choices.
245/75R16 is a metric radial size where 245 identifies the nominal section width in millimeters, 75 is the aspect ratio, R indicates radial construction, and 16 is the wheel diameter in inches. On the 1999 Lincoln Trucks Navigator, it is one of the primary fitments and appears on both covered drivetrain configurations. Available product choice in this size includes a BFGoodrich All-Terrain T/A KO2 with raised white letter sidewalls, giving the Navigator a more truck-oriented look. This size makes sense when the vehicle retains the correct 16-inch wheel setup and the goal is to match that fitment with an appropriate radial tire.
255/75R17 is a metric radial size in which 255 denotes nominal section width in millimeters, 75 describes the sidewall profile relative to width, R marks radial construction, and 17 identifies the wheel diameter. For the 1999 Lincoln Trucks Navigator, this size applies to certain 4x4 configurations and should not be assumed for every model. The larger rim diameter makes wheel confirmation especially important before any tire is selected. This is the size to evaluate when the Navigator is equipped with the corresponding 17-inch wheel package and the buyer wants to stay with the proper primary fitment.
Sub-model fitment matters on the 1999 Lincoln Trucks Navigator because tire size is not completely uniform across the range. The 4x2 uses one primary size, while the 4x4 can appear with either of two sizes depending on the wheel setup, so confirming the exact configuration and rim diameter comes first.

1999 Lincoln Trucks Navigator 4x2
The 1999 Lincoln Trucks Navigator 4x2 uses a straightforward radial fitment centered on 245/75R16. That keeps tire selection focused on choosing the right product style and intended road use rather than sorting through multiple primary sizes.
The 1999 Lincoln Trucks Navigator 4x4 can use either 245/75R16 or 255/75R17, so wheel diameter needs to be verified before a tire is chosen. That makes this sub-model more dependent on checking the actual wheel and current setup, especially if changes were made over the years.
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.

These FAQs focus on the exact tire sizes used on the 1999 Lincoln Trucks Navigator, how fitment changes between 4x2 and 4x4 models, and what to check when choosing tires for road use, wheel compatibility, and long-term ownership.
Tire Size & Fitment
What tire size fits a 1999 Lincoln Trucks Navigator?
A 1999 Lincoln Trucks Navigator uses either 245/75R16 or 255/75R17, both in radial construction. The 4x2 model uses 245/75R16, while the 4x4 can use 245/75R16 or 255/75R17 depending on the wheel setup.
The most important step is matching the tire to the actual wheel diameter on the vehicle rather than assuming every Navigator uses the same size. A 16-inch tire and a 17-inch tire are not interchangeable, so checking the current wheel, the existing tire size, and overall clearance is the right starting point before comparing products.
What size rim does a 1999 Lincoln Trucks Navigator use?
The 1999 Lincoln Trucks Navigator uses either a 16-inch or 17-inch rim, depending on the tire size and configuration. A 245/75R16 tire mounts on a 16-inch rim, while a 255/75R17 tire mounts on a 17-inch rim.
Rim diameter is the first fitment detail to confirm because the correct tire must match it exactly. It also helps to verify wheel width before choosing a specific tire, especially on a vehicle that may have seen aftermarket wheel changes, because overall tire compatibility depends on more than diameter alone.
Do all 1999 Lincoln Trucks Navigator sub-models use the same tire size?
No, the covered sub-models do not all share one tire size. The 1999 Lincoln Trucks Navigator 4x2 uses 245/75R16, while the 4x4 can use either 245/75R16 or 255/75R17.
That difference means sub-model and wheel confirmation matter before replacing tires. On a 4x4, the safest approach is to inspect the wheel diameter and the size currently mounted rather than selecting by model name alone, since two primary fitments are associated with that drivetrain configuration.
Choosing the Right Tire
What should I consider when choosing a 245/75R16 tire for a 1999 Lincoln Trucks Navigator?
Start with the correct size, radial construction, and wheel compatibility. For the 1999 Lincoln Trucks Navigator, 245/75R16 is a primary fitment, and available products in this size can differ in tread character, sidewall presentation, rim-width specification, and load rating.
Selection comes down to how the Navigator is used and how you want it to look. A tire with an all-terrain personality and raised white letter sidewalls gives a more truck-oriented appearance, while the wheel width, load requirement, and overall vehicle setup should still be checked so the choice suits the vehicle as it sits today.
What sidewall styles are available for 1999 Lincoln Trucks Navigator tires?
Available sidewall treatment for the 1999 Lincoln Trucks Navigator includes RWL, or raised white letter, in the 245/75R16 product selection. That gives the tire a more visible performance-truck appearance than a plain black sidewall would.
Sidewall style is mainly an appearance decision once the correct size and construction have been confirmed. On an SUV like the Navigator, raised white letters can shift the look toward a more rugged, late-1990s truck presentation, so it is worth deciding whether visual character matters as much as tread pattern and fitment details.
What brands offer tires for the 1999 Lincoln Trucks Navigator?
BFGoodrich is represented in the available tire selection for the 1999 Lincoln Trucks Navigator, including a 245/75R16 All-Terrain T/A KO2 radial. Brand choice is only part of the decision, since the size, rim match, and intended use still need to line up first.
A useful comparison starts with whether the product matches the vehicle’s wheel diameter and how the Navigator will be driven. After that, details such as sidewall styling, tire series, load specification, and wheel-width compatibility help narrow the choice more effectively than brand name alone.
Restoration & Appearance
Which tire should I choose for a period-style 1999 Lincoln Trucks Navigator?
A period-style choice starts with using the correct primary size for the specific 1999 Lincoln Trucks Navigator configuration, either 245/75R16 or 255/75R17. Because this is a late-1990s luxury SUV with radial fitments, keeping the proper metric radial size does the most to preserve the vehicle’s intended stance and overall look.
Appearance then comes down to tread style and sidewall presentation rather than bias-ply versus radial construction. A raised white letter tire can lean into a more truck-oriented late-1990s visual character, but owners focused on exact historical presentation should compare that look against period photos, original literature, or marque-specific references.
Does correct tire fitment matter for a 1999 Lincoln Trucks Navigator restoration?
Yes, correct tire fitment matters because tire size strongly affects how a 1999 Lincoln Trucks Navigator sits, fills the wheel opening, and presents itself visually. Using the proper 16-inch or 17-inch fitment helps maintain the right proportions for the SUV’s original wheel-and-tire relationship.
Restoration-minded owners should confirm both the tire size and the wheel diameter before making appearance decisions. Even when the overall look seems close, a mismatched diameter or an incorrect profile can change stance and visual balance, so size accuracy should come before choosing tread style or sidewall treatment.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1999 Lincoln Trucks Navigator?
Yes, modifications can affect tire fitment on a 1999 Lincoln Trucks Navigator. Aftermarket wheels, suspension changes, altered ride height, and body or steering changes can all influence whether the original tire size still matches the vehicle’s current setup.
That is especially important here because the Navigator already has two primary sizes tied to different wheel diameters. A modified vehicle should be checked for wheel diameter, wheel width, clearance at full steering lock, and any signs of rubbing before assuming either original tire size remains appropriate for the way the SUV is configured now.
What should I inspect before driving a 1999 Lincoln Trucks Navigator on new tires?
Before driving on new tires, inspect the wheel condition, verify the wheel diameter matches the tire size, and make sure the tires are inflated properly for the application. It is also wise to check for clearance around the fenders, suspension, and steering components once the tires are mounted.
A full road-use check should also include lug hardware, alignment condition, and any uneven wear clues from the old tires. On an older SUV, worn suspension parts can affect how a new tire behaves, so taking a close look at shocks, bushings, and steering components can help avoid fitment or wear issues early.
How often should tires on a 1999 Lincoln Trucks Navigator be inspected?
Tires on a 1999 Lincoln Trucks Navigator should be inspected regularly, not just when tread looks low. Pressure, visible cracking, cuts, bulges, uneven wear, and slow air loss are all worth checking because age and storage conditions can matter as much as mileage on an older vehicle.
A quick visual check before routine driving is a smart habit, with a more thorough inspection before longer trips. Vehicles that sit for extended periods deserve extra attention because flat spotting, sidewall aging, and pressure loss can develop quietly, even when the SUV has not been driven often.
