The 2006 Lincoln Trucks Mark LT brought Lincoln trim and upscale presentation into the full-size pickup market, giving buyers a luxury-minded alternative built around truck capability. That mix of comfort, appearance, and utility makes tire selection especially important, because the exact setup depends on whether the truck is a 4x2, 4x4, or fitted with the 20-inch wheel option. This model uses radial tire fitments only, with three different metric radial sizes across its covered configurations. The decision is less about vintage construction and more about matching the correct wheel diameter, overall stance, and intended road or truck use.
Which Tire Size Is Right for The 2006 Lincoln Trucks Mark LT
Three primary tire sizes apply to the 2006 Lincoln Trucks Mark LT, and the correct one depends on the truck's exact configuration. Two sizes use 18-inch rims, while the 20 Inch Option uses a 20-inch rim, so the first step is confirming both the sub-model and the wheel diameter already on the truck. Once that is settled, the decision shifts to selecting the right radial tire for the truck's use and wheel setup.
The size 275/55R20 identifies a metric radial tire that is 275 millimeters wide, uses a 55-series aspect ratio, and mounts on a 20-inch rim. On the 2006 Lincoln Trucks Mark LT, this size belongs to the 20 Inch Option and suits the truck's larger-wheel configuration rather than the 18-inch setups used on other versions. Its lower-profile format gives this fitment a different visual character from the taller 18-inch alternatives. This is the size to evaluate when the truck already carries factory-style 20-inch wheels or an equivalent 20-inch wheel package.
The size 265/60R18 is a metric radial with a 265-millimeter section width, a 60-series profile, and an 18-inch rim diameter. On the 2006 Lincoln Trucks Mark LT, this size is used on the 4x2 configuration, making it distinct from both the 4x4 tire and the 20-inch option. Its sizing format is familiar to modern truck owners and centers the fitment decision on the exact chassis and wheel package rather than vintage construction choices. This is the size to confirm when matching an 18-inch 4x2 truck and preserving the proper wheel diameter.
The size 275/65R18 is a metric radial tire with a 275-millimeter width, a 65-series profile, and fitment on an 18-inch rim. This size is used on the 2006 Lincoln Trucks Mark LT 4x4, so it should not be treated as interchangeable with the 4x2's 265/60R18 or the separate 20-inch-wheel setup. Available product choice in this size includes the BFGoodrich All-Terrain T/A KO2 with raised white letter sidewalls, giving the truck a more assertive all-terrain presentation. It is the right place to look when the truck has the 4x4 configuration and needs an 18-inch radial with truck-oriented character.
Tire fitment for the 2006 Lincoln Trucks Mark LT varies by sub-model and wheel package rather than staying uniform across the lineup. Checking whether the truck is a 4x2, a 4x4, or the 20 Inch Option is the key step before choosing a tire.

2006 Lincoln Trucks Mark LT (20 Inch Option)
The 2006 Lincoln Trucks Mark LT (20 Inch Option) uses a 275/55R20 radial tire, setting it apart from the 18-inch-wheel trucks. Tire selection here starts with preserving the 20-inch rim diameter and then choosing a radial tire that matches the truck's wheel and clearance setup.
The 2006 Lincoln Trucks Mark LT 4x2 uses the 265/60R18 radial size. That makes wheel confirmation straightforward, but it still matters to match the 4x2 fitment correctly rather than assuming the larger 4x4 size or 20-inch option belongs on the truck.
The 2006 Lincoln Trucks Mark LT 4x4 uses a 275/65R18 radial tire on an 18-inch rim. That fitment opens the door to truck-oriented choices such as an all-terrain radial, while keeping wheel width, intended use, and clearance in view before making a change.
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.

Owners of a 2006 Lincoln Trucks Mark LT usually need to sort out exact tire size by sub-model, wheel diameter, and intended use. These FAQs focus on fitment differences, radial tire selection, appearance choices, and practical checks before road use.
Tire Size & Fitment
What tire size fits a 2006 Lincoln Trucks Mark LT?
The 2006 Lincoln Trucks Mark LT uses three different tire sizes depending on configuration: 275/55R20 for the 20 Inch Option, 265/60R18 for the 4x2, and 275/65R18 for the 4x4. All three are radial metric sizes, but they are not universal across every Mark LT setup.
Choosing the right size starts with identifying the exact sub-model and confirming the wheel diameter already on the truck. An 18-inch Mark LT should not automatically be matched to the 20-inch option, and the two 18-inch sizes still differ by configuration, so checking the current wheel and vehicle setup matters before replacement.
What size rim does a 2006 Lincoln Trucks Mark LT use?
A 2006 Lincoln Trucks Mark LT uses either an 18-inch or 20-inch rim, depending on the truck's configuration. The 4x2 uses 18-inch fitment with 265/60R18 tires, the 4x4 uses 18-inch fitment with 275/65R18 tires, and the 20 Inch Option uses 275/55R20 tires.
Rim diameter should be confirmed before anything else because the tire sizes are built around two different wheel diameters. A quick visual assumption can lead to the wrong tire, especially when comparing 18-inch trucks with the 20-inch option, so verifying the actual wheel on the truck is the safest starting point.
Why does the 2006 Lincoln Trucks Mark LT have more than one tire size?
The 2006 Lincoln Trucks Mark LT has more than one tire size because fitment changes with the truck's sub-model and wheel package. The 4x2, 4x4, and 20 Inch Option each use a different radial tire size, so the truck was not built around one shared fitment across every covered version.
That matters because selecting a tire for this model is not just a matter of picking any Mark LT size that looks close. The correct approach is to match the tire to the specific configuration first, then compare choices within that size based on wheel compatibility, intended use, and the overall stance you want to maintain.
Choosing the Right Tire
What should I consider when choosing a tire for a 2006 Lincoln Trucks Mark LT?
Start with the exact tire size that matches the truck's configuration, because the 2006 Lincoln Trucks Mark LT uses different fitments for the 4x2, 4x4, and 20 Inch Option. After size and rim diameter are confirmed, the next priorities are construction, wheel-width compatibility, and whether the truck is used mainly on pavement or in more demanding truck conditions.
A luxury pickup like the Mark LT can be sensitive to the visual and functional difference between wheel packages, so maintaining the proper size matters for both appearance and fitment. Product details such as sidewall style, tire series, load capacity, and rim-width range become more useful once the correct size is established.
What sidewall styles are available for 2006 Lincoln Trucks Mark LT tires?
Available sidewall style depends on the exact tire size and product being considered. In the 275/65R18 fitment used on the 2006 Lincoln Trucks Mark LT 4x4, an available BFGoodrich All-Terrain T/A KO2 uses RWL, or raised white letter, sidewalls for a more pronounced truck-style appearance.
Sidewall treatment affects the truck's presentation as much as the tread pattern does, especially on a full-size luxury pickup that may lean either upscale or more rugged in appearance. Matching the sidewall style to the truck's purpose and look can help narrow the field once the correct size and wheel setup have been confirmed.
What brands offer tires for the 2006 Lincoln Trucks Mark LT?
BFGoodrich is available in the 275/65R18 fitment for the 2006 Lincoln Trucks Mark LT. That option appears as the All-Terrain T/A KO2, a radial truck tire that suits the 4x4 configuration and adds a more aggressive visual character through its raised white letter sidewall treatment.
Brand choice is most useful after confirming the exact sub-model and tire size, because a product offered in one Mark LT fitment should not be assumed to apply to the others. Comparing the tire's series, sidewall style, wheel-width range, and load specification gives a more practical picture than brand name alone.
Restoration & Appearance
Which tire should I choose for a period-style 2006 Lincoln Trucks Mark LT?
A period-style choice for a 2006 Lincoln Trucks Mark LT starts with keeping the truck on its correct size and wheel diameter for the exact configuration. That means 275/55R20 for the 20 Inch Option, 265/60R18 for the 4x2, or 275/65R18 for the 4x4 rather than substituting a different Mark LT fitment for appearance alone.
Because this is a modern luxury pickup rather than an earlier collector car with bias-ply decisions, the appearance question is more about preserving the truck's intended stance and wheel package. Sidewall treatment and tread character can then be used to lean the look toward more refined street use or a more rugged truck presentation.
How does tire construction affect the appearance of a restored 2006 Lincoln Trucks Mark LT?
Tire construction is straightforward on the 2006 Lincoln Trucks Mark LT because its primary fitments are radial sizes throughout. That means the appearance difference comes less from choosing between bias-ply and radial construction and more from selecting the correct metric size, sidewall treatment, and tire series for the truck's wheel package.
A restored or exceptionally clean Mark LT can look noticeably different if the tire profile or wheel diameter is changed from the proper configuration. Keeping the correct size for the specific sub-model preserves the truck's proportions, while details such as raised white letters or a more subdued sidewall influence how formal or truck-oriented the finished look feels.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2006 Lincoln Trucks Mark LT?
Yes, modifications can affect tire fitment on a 2006 Lincoln Trucks Mark LT, even when the tire size is correct for the original configuration. Aftermarket wheels, changes in wheel width, altered offset, suspension lifts or lowering, and body modifications can all change how an 18-inch or 20-inch tire sits in the wheel opening.
That is especially important on a model with more than one factory tire size, because the truck may already differ from stock before replacement begins. Checking steering clearance, fender clearance, and actual wheel dimensions on the truck helps prevent choosing a tire solely by model name without confirming the current setup.
What should I inspect before driving a 2006 Lincoln Trucks Mark LT on new tires?
Before driving a 2006 Lincoln Trucks Mark LT on new tires, inspect wheel condition, verify that the installed tire size matches the truck's configuration, and confirm proper inflation for the tire in use. It is also smart to look over the suspension, alignment condition, and any signs that previous tires rubbed or wore unevenly.
A short visual check after installation can prevent bigger problems later. Look for adequate clearance at full steering lock, listen for rubbing on the first drive, and keep an eye on air pressure as the tires settle into service, especially if the truck has replacement wheels or sees a mix of highway and truck duty.
What should I check before a longer drive in a 2006 Lincoln Trucks Mark LT?
Before a longer drive in a 2006 Lincoln Trucks Mark LT, confirm tire pressure, inspect tread and sidewalls, and make sure the tire size on the truck matches the correct 4x2, 4x4, or 20-inch configuration. It also helps to check for cuts, bulges, embedded debris, and any slow air loss that may not show up in everyday short trips.
Longer highway use puts more emphasis on heat, load, and stability, so a quick inspection is worth doing even on a truck that is driven regularly. Owners using the 275/65R18 4x4 fitment should also confirm that the tire suits the truck's intended use and wheel width before adding distance or cargo.
