The 2006 Lincoln Trucks Navigator sits in the full-size luxury SUV era when comfort, presence, and towing-capable utility were expected to live in the same package. Buyers looking at this exact Navigator are usually balancing everyday road use with the need to keep the truck's stance and fitment appropriate to its original wheel setup. This model uses radial tires in two metric 18-inch sizes, 255/70R18 and 275/65R18, so the first step is confirming which size is on the vehicle now. That size decision also shapes sidewall appearance and product choice, especially if the truck is used for highway driving, light truck duty, or a more assertive period-appropriate SUV presentation.
Which Tire Size Is Right for The 2006 Lincoln Trucks Navigator
The 2006 Lincoln Trucks Navigator uses two primary tire sizes, and both are radial tires built for 18-inch rims. Since both the Luxury and Ultimate sub-models can use either size, the key step is confirming the actual wheel and tire setup on the truck before choosing a replacement. Once that is settled, the decision shifts to section width, intended use, and the product features available in that exact size.
255/70R18 is a metric radial size in which 255 refers to nominal section width in millimeters, 70 is the aspect ratio, R identifies radial construction, and 18 is the rim diameter in inches. On the 2006 Lincoln Trucks Navigator, this size represents a modern SUV fitment with a full-profile sidewall on an 18-inch wheel. Its dimensions make it an important reference point when comparing replacement tires against the truck's current setup. Choosing this size starts with verifying that the vehicle still carries the same wheel package and has not been changed to a wider tire arrangement.
275/65R18 is also a metric radial size, with a wider 275-millimeter section width, a 65-series profile, radial construction, and an 18-inch rim diameter. For the 2006 Lincoln Trucks Navigator, it offers another primary fitment path while staying on the same wheel diameter as the 255/70R18 size. Available options in this size can include a more truck-oriented presentation, such as BFGoodrich's All Terrain T/A KO2 with raised white lettering. This size is worth considering only after confirming that the wheel width and current truck setup match the wider tire properly.
Tire fitment is relatively straightforward because both covered sub-models share the same two primary 18-inch radial sizes. The important step is not trim identification alone, but confirming which of those two sizes is actually mounted on the vehicle before selecting a replacement.

2006 Lincoln Trucks Navigator Luxury
The 2006 Lincoln Trucks Navigator Luxury can use either of the two primary radial sizes offered for this model year. That means tire selection comes down to confirming the truck's present wheel-and-tire setup, then choosing the size and tread style that best match its current use and appearance.
The 2006 Lincoln Trucks Navigator Ultimate also uses the same two primary radial tire sizes found on the Luxury trim. Selecting the right tire starts with checking which size is already on the truck, then comparing available options for width, sidewall style, and intended road or light-truck 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.

Tire Size & Fitment
What tire size fits a 2006 Lincoln Trucks Navigator?
The 2006 Lincoln Trucks Navigator uses two primary tire sizes: 255/70R18 and 275/65R18. Both are radial metric sizes built for 18-inch rims, and both the Luxury and Ultimate sub-models can use these sizes.
That means the right replacement starts with checking the truck itself rather than assuming one size applies to every vehicle the same way. Compare the current tire sidewall, confirm the wheel diameter, and make sure the Navigator has not been changed with aftermarket wheels or previous size substitutions before choosing a replacement.
What size rim does a 2006 Lincoln Trucks Navigator use?
Both primary tire sizes for the 2006 Lincoln Trucks Navigator are built around an 18-inch rim diameter. Whether the truck is running 255/70R18 or 275/65R18, the tire is intended for an 18-inch wheel.
Rim diameter is the first fitment check because a tire must match the wheel's diameter exactly. After that, wheel width still matters, especially when comparing a narrower 255-section tire to a wider 275-section tire, so it helps to confirm the actual wheel setup before ordering or mounting new tires.
Do all 2006 Lincoln Trucks Navigator sub-models use the same tire size?
The 2006 Lincoln Trucks Navigator Luxury and Ultimate share the same two primary tire sizes, 255/70R18 and 275/65R18. That keeps fitment simpler than on vehicles where each trim uses a different diameter or construction.
Even with shared sub-model fitment, the truck still needs to be checked individually because one Navigator may be wearing the narrower size while another uses the wider one. Looking at the current sidewall marking and confirming the wheel package is the most reliable way to choose the correct replacement for that specific vehicle.
Choosing the Right Tire
What should I consider when choosing a tire for a 2006 Lincoln Trucks Navigator?
Start with the exact size already fitted to the truck, since the 2006 Lincoln Trucks Navigator uses either 255/70R18 or 275/65R18 on an 18-inch rim. Construction is straightforward because both primary sizes are radial, so the main comparison points become size, wheel compatibility, and intended use.
After size is confirmed, think about how the Navigator is driven and how you want it to present. A road-oriented setup and a more truck-focused tread can lead to different choices, and a wider tire should always be checked against wheel width and clearance before replacing what is already on the vehicle.
What sidewall styles are available for 2006 Lincoln Trucks Navigator tires?
Sidewall styling can affect the overall look of a 2006 Lincoln Trucks Navigator as much as the tread itself. In the available 275/65R18 product range, one of the sidewall treatments offered is RWL, or raised white lettering.
That type of sidewall gives the Navigator a more assertive SUV and light-truck appearance than a plain blackwall tire. Sidewall style does not change the need for correct size and wheel fitment, but it does matter if the goal is to keep the truck looking closer to its original era rather than giving it a more generic replacement-tire appearance.
What brands offer tires for the 2006 Lincoln Trucks Navigator?
BFGoodrich is represented in the available product selection for the 2006 Lincoln Trucks Navigator, specifically in the 275/65R18 size. That option appears in the All Terrain T/A KO2 series and uses radial construction.
Brand is only one part of the decision, so it helps to compare the tire's overall character as well. On a Navigator, the more useful questions are whether the size matches the truck, whether the wheel width is appropriate, and whether the tread and sidewall style suit the way the vehicle is actually used.
Restoration & Appearance
Which tire should I choose for a period-style 2006 Lincoln Trucks Navigator?
A period-style choice for a 2006 Lincoln Trucks Navigator starts with staying in one of its correct primary sizes, 255/70R18 or 275/65R18, and keeping the truck on the proper 18-inch rim diameter. Since this is a modern luxury SUV fitment, radial construction is already part of the original-era look.
Appearance then comes down to how closely the replacement matches the truck's intended personality. A more highway-oriented tire keeps a cleaner luxury-SUV presentation, while an all-terrain design can push the look toward a tougher truck stance, so the best choice depends on whether the goal is preservation, light use, or visual attitude.
How does tire construction affect the appearance of a restored 2006 Lincoln Trucks Navigator?
On the 2006 Lincoln Trucks Navigator, construction does not create a bias-ply versus radial decision because the primary fitments are radial. The visual effect comes more from the exact size, tread style, and sidewall treatment than from changing between different tire constructions.
That makes size discipline especially important on a restoration-minded truck. A tire that stays within the proper 18-inch fitment and preserves the Navigator's intended proportions will usually support a more authentic early-2000s presentation than an oversized or heavily altered setup, even when both choices are technically radial.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2006 Lincoln Trucks Navigator?
Yes, modifications can change how either 255/70R18 or 275/65R18 works on a 2006 Lincoln Trucks Navigator. Aftermarket wheels, changes in wheel width, suspension alterations, ride-height changes, or body modifications can all affect clearance and the way a replacement tire sits on the vehicle.
That matters even when the tire size itself is one of the correct original fitments. A wider tire can react differently on a non-stock wheel, so checking wheel width, steering clearance, and space at the fender and suspension points is a smart step before replacing tires on a modified Navigator.
What should I inspect before driving a 2006 Lincoln Trucks Navigator on new tires?
Before driving a 2006 Lincoln Trucks Navigator on new tires, inspect the wheels for damage, confirm the tire size matches the intended wheel diameter, and make sure the tires are seated and inflated correctly. It also helps to check for any signs of rubbing at full steering lock or through normal suspension travel.
A road test should be paired with a quick look at the rest of the truck's condition. Uneven suspension wear, alignment issues, or worn steering parts can affect how a new tire behaves, so taking a few minutes to check those items helps protect both the tires and the overall drivability of the Navigator.
How often should tires on a 2006 Lincoln Trucks Navigator be inspected?
Tires on a 2006 Lincoln Trucks Navigator should be inspected regularly, not just when tread looks low. Pressure, tread wear, sidewall condition, punctures, cracking, and any unusual bulges deserve attention, especially on a heavy full-size SUV that may see family use, highway miles, or towing-related service.
A quick visual check before longer trips is a good habit, and a closer inspection during routine maintenance can catch problems early. Consistent inspections are also helpful when the truck has sat for periods of time, since age, slow air loss, and flat-spotting can affect a vehicle that is not driven every day.
