2006 Lincoln Trucks blended luxury-brand presentation with full-size SUV and pickup capability, giving buyers a premium take on the era’s body-on-frame truck market. The Mark LT brought Lincoln trim to a luxury pickup formula, while the Navigator continued as the make’s flagship sport-utility. Across 2006 Lincoln Trucks, four tire sizes appear across two models, with one shared 18-inch size and three model-specific radial sizes that separate the pickup from the SUV. The key first step is confirming whether you have a Mark LT or a Navigator, then checking whether your truck uses an 18-inch or 20-inch wheel before narrowing down the correct tire.
Which Tire Size Is Right for Your 2006 Lincoln Trucks
Four tire sizes were used across 2006 Lincoln Trucks, and they vary by model rather than being universal across the full range. All four are radial sizes, so the real decision starts with identifying your model and confirming whether your truck uses an 18-inch or 20-inch wheel. Understanding that distinction before choosing a product saves time and helps match the right tire to the right vehicle.
Year(s): 2006|Fit(s): Mark LT|Construction: Radial|Rim: 20-in
275/55R20 is a metric radial size with a 275-millimeter section width, a 55-series aspect ratio, and a 20-inch rim diameter. This size is specific to the Mark LT rather than shared across all 2006 Lincoln Trucks models. It suits owners who need to stay with the larger factory-style wheel diameter used on certain Mark LT applications and should confirm the actual wheel before choosing a tire.
Year(s): 2006|Fit(s): Mark LT|Construction: Radial|Rim: 18-in
265/60R18 is a metric radial size with a 265-millimeter section width, a 60-series aspect ratio, and an 18-inch rim diameter. This size is specific to the Mark LT and is separate from the Navigator-specific 18-inch sizing used elsewhere in the 2006 Lincoln Trucks range. It is the right path for a Mark LT owner who has confirmed an 18-inch wheel and wants to stay with that original diameter family.
Year(s): 2006|Fit(s): Mark LT, Navigator|Construction: Radial|Rim: 18 in
275/65R18 is a metric radial size with a 275-millimeter section width, a 65-series aspect ratio, and an 18-inch rim diameter. BFGoodrich offers this size with an RWL sidewall, tubeless construction, and an R speed rating with a 106 mph ceiling; load capacity reaches 3,415 pounds at 80 psi, and the approved rim width range is 7.5 to 9.5 inches. Because this size fits both the Mark LT and Navigator, it is the shared 18-inch option for buyers who have verified that wheel diameter and want a truck-oriented radial in that fitment.
255/70R18 is a metric radial size with a 255-millimeter section width, a 70-series aspect ratio, and an 18-inch rim diameter. This size is specific to the Navigator and is not shared across the full 2006 Lincoln Trucks lineup. It is the correct direction for Navigator owners who have confirmed that narrower 18-inch fitment rather than assuming every Lincoln truck in 2006 used the same tire.
Two models are covered for 2006 Lincoln Trucks. Tire size varies by model, with the Mark LT using three sizes and the Navigator using two, so identifying the exact model matters before choosing a tire. Select your model below to narrow the fitment history and see the sizes that apply to your truck.
2006 Lincoln Trucks Mark LT
The 2006 Lincoln Trucks Mark LT was Lincoln’s luxury pickup, pairing full-size truck utility with a more upscale cabin and exterior trim than a mainstream work truck. Its tires mount on either 18-inch or 20-inch wheels depending on the application, which makes wheel-diameter verification especially important before moving to a size-specific page.
The 2006 Lincoln Trucks Navigator remained Lincoln’s flagship full-size SUV, known for combining premium comfort with substantial size and towing-oriented truck underpinnings. Its tire fitments stay within the 18-inch wheel family, but the exact size still changes depending on the setup, so matching the truck to the correct size matters.
One product is available across four tire sizes for 2006 Lincoln Trucks vehicles. The 275/65R18 offers one BFGoodrich radial with an RWL sidewall; confirm your exact size and wheel diameter before selecting a tire.
These answers focus on how 2006 Lincoln Trucks tire sizes differ between the Mark LT and Navigator, what the metric size codes mean, and what to verify about wheel diameter, rim width, load capacity, and longer-term collector-style tire care.
Size Basics & Fitment
What tire sizes fit 2006 Lincoln Trucks vehicles?
2006 Lincoln Trucks vehicles use four tire sizes across two models: 275/55R20, 265/60R18, 275/65R18, and 255/70R18. The Mark LT uses 275/55R20, 265/60R18, and 275/65R18, while the Navigator uses 255/70R18 and 275/65R18. That means 275/65R18 is the only size shared by both models. Where wheel information is confirmed, 275/65R18 fits an 18-inch rim and works with rim widths from 7.5 to 9.5 inches.
The practical takeaway is that year and make alone are not enough for 2006 Lincoln Trucks. You need to identify whether you have a Mark LT or Navigator, then confirm whether the truck is on 18-inch or 20-inch wheels. That matters more than anything else at the first step, because three of the four sizes are model-specific and one of them also changes rim diameter. Once that is settled, moving to the model page or exact size page becomes much more straightforward.
What does 275/65R18 mean on a 2006 Lincoln Trucks tire?
On a 2006 Lincoln Trucks tire, 275/65R18 is a metric radial size. The 275 is the nominal section width in millimeters, the 65 is the aspect ratio, the R means radial construction, and the 18 is the wheel diameter in inches. For 2006 Lincoln Trucks, this size fits both the Mark LT and Navigator and is available as a BFGoodrich All-Terrain T/A KO2 with an R speed rating, which carries a 106 mph ceiling.
That code matters because it tells you both physical fitment and the general type of tire you are dealing with. Since 275/65R18 is shared across both Lincoln truck models for 2006, it can look like the easy answer, but you still need to confirm that your truck actually has the correct 18-inch wheels. It is also wise to check the actual tire service description and approved rim-width range when replacing only one or two tires rather than a full set.
Do all 2006 Lincoln Trucks models use the same tire size?
No, 2006 Lincoln Trucks models do not all use the same tire size. The Mark LT uses three sizes—275/55R20, 265/60R18, and 275/65R18—while the Navigator uses 255/70R18 and 275/65R18. Only 275/65R18 overlaps between the two models, so the fitment picture changes depending on whether the truck is a luxury pickup or a full-size SUV.
That difference means buyers should not assume that any 18-inch Lincoln truck tire from 2006 is interchangeable across the whole range. Even when two sizes share the same wheel diameter, section width and aspect ratio still affect overall dimensions and intended application. Start with the model badge, then verify the current wheel diameter and the tire size already on the truck or on the door placard. That prevents cross-shopping the wrong size simply because the year and make match.
Buying the Right Tire
What sidewall styles are available for 2006 Lincoln Trucks tires?
Sidewall style availability for 2006 Lincoln Trucks depends on the exact size. Within the currently covered fitments, 275/65R18 is available with an RWL, or raised white letter, sidewall. That gives the shared Mark LT and Navigator size a more truck-oriented visual character than a plain blackwall would. All sizes in this year-make range are radial, so sidewall appearance becomes one of the visible differences once fitment is confirmed.
For many owners, sidewall style is partly a visual choice and partly a style cue that should match how the truck is used or restored. A raised white letter sidewall can look at home on a period 2000s luxury truck with an all-terrain theme, while an owner pursuing a more understated look may prefer to compare other size-specific options as they become relevant to the truck. Confirm the exact size first, then compare sidewall appearance within that fitment rather than across the whole year and make.
What brands make tires for 2006 Lincoln Trucks vehicles?
BFGoodrich is represented in 2006 Lincoln Trucks fitments through the 275/65R18 size, where the All-Terrain T/A KO2 is available for both the Mark LT and Navigator. That gives the shared 18-inch fitment a well-known light-truck brand with an established all-terrain identity. The other 2006 Lincoln Trucks sizes on this page are separate fitments, so brand availability depends on moving into the specific size or model path that matches your truck.
Brand matters less than correct size, wheel diameter, and service category at the start of the search. Once those basics are settled, a buyer can compare tread style, sidewall appearance, and load capacity within the correct fitment family. For a 2006 luxury truck or SUV, that is especially useful because a premium street-oriented setup and a more rugged all-terrain look can lead to very different tire choices even when the wheel diameter is the same.
What is the difference between the BFGoodrich All-Terrain T/A KO2 and other 2006 Lincoln Trucks tire choices?
For 2006 Lincoln Trucks, the BFGoodrich All-Terrain T/A KO2 appears in 275/65R18, the size shared by the Mark LT and Navigator. In that fitment it carries a 123/120R service description, supports up to 3,415 pounds at 80 psi, fits 18-inch rims from 7.5 to 9.5 inches wide, and uses an RWL sidewall. That combination points to a truck-focused radial with substantial load capability and a more aggressive visual character than a typical highway-style tire.
The main buyer implication is use case. If your 2006 Lincoln Trucks vehicle runs 275/65R18 and you want a more utility-minded or all-terrain presentation, the KO2 sits in that lane. If your truck uses one of the other year-make sizes instead, the question shifts from comparing product series to first confirming the right dimensions. Cross-comparing products in the wrong size is far less helpful than getting the fitment family right before you evaluate tread style or appearance.
Fitting & Setup
What rim width do 2006 Lincoln Trucks tires require?
For 2006 Lincoln Trucks, confirmed rim-width guidance is available for 275/65R18. That size fits an 18-inch wheel and works with rim widths from 7.5 to 9.5 inches. The other 2006 Lincoln Trucks sizes on this page also identify their wheel diameters through the size code itself—18 or 20 inches—but rim-width selection should still be checked against the exact tire and wheel combination before installation.
Rim width matters because a tire can share the right rim diameter yet still be mismatched to the wheel if the width falls outside the approved range. That can affect how the tire seats, how the tread sits on the road, and how the sidewall looks under load. For replacement work on an older luxury truck or SUV, it is smart to confirm the actual wheel dimensions rather than assume that every factory-appearing 18-inch wheel is identical.
Do 2006 Lincoln Trucks tires require inner tubes?
The 275/65R18 fitment for 2006 Lincoln Trucks is tubeless. Its service description does not carry a tube-type marking, and it follows the modern radial light-truck pattern typical of the period. The other 2006 Lincoln Trucks sizes on this page are also modern radial metric sizes, so the starting expectation is a tubeless wheel-and-tire setup rather than a tube-required vintage arrangement.
Even so, tube use is ultimately a wheel question as much as a tire question. If a wheel has damage, corrosion, or has been modified, an owner should confirm whether it still supports proper tubeless service before mounting a new tire. On a 2006 vehicle, valve stem condition also matters; replacing tires is a good time to inspect or renew stems so the assembly holds pressure as intended.
Maintenance, Storage & Longevity
How should I store a 2006 Lincoln Trucks when the tires are fitted?
A 2006 Lincoln Trucks vehicle should be stored on clean, properly inflated tires away from direct sunlight, standing moisture, electric motors, welders, battery chargers, and other ozone-producing equipment. Radial tires generally tolerate static storage better than older bias-ply designs, but they still age from heat, UV exposure, and long periods without movement. If the truck will sit for an extended time, keeping it on a dry surface and moving it occasionally helps avoid flat spotting and stress concentration in one footprint area.
Long-term storage is also a good time to think about the whole assembly, not just the tread. Check sidewalls for weathering, keep the tires clean without petroleum-based dressings, and consider using stands if the truck will be parked for a very long stretch with weight on one spot. A luxury SUV or pickup often sits seasonally, so a little storage discipline goes a long way toward preserving tire shape, appearance, and ride quality.
How long do tires on a 2006 Lincoln Trucks typically last?
Tires on a 2006 Lincoln Trucks vehicle should be judged more by age and condition than by mileage alone, especially if the truck is lightly used. A sensible rule is to begin close evaluation around five to seven years and give serious replacement consideration as tires approach ten years, regardless of remaining tread depth. The DOT date code on each tire reveals its week and year of manufacture, which is essential on collector-driven or low-mileage vehicles.
A luxury truck can look road-ready while riding on tires that are old enough to deserve retirement. Sidewall cracking, hardening rubber, irregular wear, or chronic pressure loss can all matter more than tread depth on a vehicle that spends much of its life parked. When evaluating a 2006 Lincoln Trucks tire set, check the date codes on all five tires if a spare is carried, because the spare may be the oldest tire on the truck.
How often should tires on a 2006 Lincoln Trucks be inspected?
Tires on a 2006 Lincoln Trucks vehicle should be inspected before every drive and more carefully before any longer trip. Look for sidewall cracking, cuts, bulges, punctures, uneven tread wear, and signs of impact damage, then verify inflation pressure when the tires are cold. Any tire that has been run underinflated, overloaded, or struck hard enough to damage the wheel deserves a closer look before the truck returns to regular road use.
Routine inspection is especially important on vehicles that alternate between long idle periods and occasional highway use. Problems can develop in storage and only reveal themselves once the tire warms up under load. If the truck sees towing, hauling, or rough-surface use, step up the inspection routine even more. Catching a damaged sidewall or aging valve stem in the garage is far preferable to finding it after the trip has already started.
Safety & Road Use
Are 2006 Lincoln Trucks tires safe for highway driving?
2006 Lincoln Trucks tires can be suitable for highway driving when the correct size, condition, inflation, and service rating are matched to the vehicle’s actual use. In the shared 275/65R18 fitment, the available BFGoodrich tire carries an R speed rating, which corresponds to a 106 mph ceiling. That is well above normal legal highway speeds, but safe road use still depends on tire age, load, inflation pressure, alignment, suspension condition, and the overall mechanical health of the truck.
For a large luxury pickup or SUV, the tire’s speed rating is only one piece of the picture. Brakes, steering components, shocks, and weight distribution all influence how confidently the truck behaves at highway speed. Before any extended road use, verify that the tires are not simply the right size, but also structurally sound and recent enough in age to inspire confidence. A fresh, properly rated tire cannot compensate for neglected chassis maintenance.
What inflation pressure should I use for 2006 Lincoln Trucks tires?
Inflation pressure for 2006 Lincoln Trucks should start with the factory vehicle recommendation for the exact model and tire size, then be checked against the tire manufacturer’s service information for the specific replacement tire. For 275/65R18, the available BFGoodrich fitment carries a maximum load of 3,415 pounds at 80 psi, but that is a load-and-pressure limit, not a blanket recommendation to run every truck at 80 psi. Pressure should always match the vehicle, tire size, and actual operating load.
Using the wrong pressure can hurt ride quality, wear pattern, braking, and stability even when the tire size itself is correct. The safest approach is to read the placard or owner information for your exact 2006 Lincoln truck, then confirm that the replacement tire’s rated capacity suits that target. If the truck tows, hauls, or carries family and cargo regularly, pressure management becomes even more important than it is on a lightly used collector example.
What should I check before taking a 2006 Lincoln Trucks on a longer drive?
Before taking a 2006 Lincoln Trucks vehicle on a longer drive, inspect each tire for cracks, bulges, punctures, tread separation, abnormal wear, and proper cold inflation pressure. Check the spare as well, since a neglected spare can leave you stranded just as effectively as a failed road tire. If your truck uses 275/65R18, confirm that the tire’s load capability remains appropriate for passengers, cargo, and any towing or travel gear you plan to carry.
Tires are only one part of the pre-trip routine on an older luxury truck or SUV. Wheel condition, brake feel, steering response, shocks, and alignment all affect how the truck treats its tires over a long day on the road. A quick local test drive after any storage period is worthwhile before committing to a full trip. That short run can reveal vibration, pull, or pressure loss early enough to correct it without roadside drama.
