In 2008, Lincoln Trucks covered a wide span of luxury utility vehicles, from the crossover-style MKX to the full-size Navigator and the upscale Mark LT pickup. That breadth matters because 2008 Lincoln Trucks models did not share one universal tire size across the lineup, and the right choice depends first on identifying the model and then confirming whether it rides on an 18-inch or 20-inch wheel. All of the sizes used across the range are radial formats, so the decision is less about old-versus-new construction and more about matching the correct dimensions to the vehicle’s intended stance, load needs, and wheel package before moving on to product selection.
Which Tire Size Is Right for Your 2008 Lincoln Trucks
Six tire sizes were used across 2008 Lincoln Trucks vehicles, and they vary by model rather than carrying across the full lineup. Because these sizes span both 18-inch and 20-inch wheel fitments, the first step is confirming your exact model and wheel diameter before comparing tire choices. Understanding that distinction up front helps narrow the search and leads to the right match more quickly.
Year(s): 2008|Fit(s): MKX|Construction: Radial|Rim: 20-in rim
245/50R20 is a metric radial size with a 245-millimeter section width, a 50-series aspect ratio, and a 20-inch rim diameter. Product details are not expanded here by brand or sidewall style, so the key point is that this is a dedicated MKX fitment rather than a size shared across all 2008 Lincoln Trucks models. Buyers looking to keep an MKX on its 20-inch wheel package should start with this size and then compare tread style, sidewall appearance, and service rating within that fitment.
Year(s): 2008|Fit(s): MKX|Construction: Radial|Rim: 18-in rim
245/60R18 is a metric radial size that uses a 245-millimeter section width, a 60-series aspect ratio, and an 18-inch rim diameter. It is specific to the MKX and gives that model a separate 18-inch fitment path from its 20-inch option. Buyers with an MKX should confirm which factory wheel package is on the vehicle first, since this size is about correct dimensional fitment rather than a construction-style choice.
Year(s): 2008|Fit(s): Mark LT, Navigator|Construction: Radial|Rim: 20-in rim
275/55R20 is a metric radial size with a 275-millimeter section width, a 55-series aspect ratio, and a 20-inch rim diameter. It is shared by the Mark LT and Navigator, making it one of the crossover sizes within the 2008 Lincoln Trucks range. If your truck or SUV carries a 20-inch wheel and falls into one of those two model lines, this is the size to confirm against the actual wheel and door-jamb tire information before selecting a product.
Year(s): 2008|Fit(s): Mark LT|Construction: Radial|Rim: 18-in rim
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 fitment belongs to the Mark LT only, so it is not universal across 2008 Lincoln Trucks vehicles. Mark LT owners should use this size when matching an 18-inch wheel package and then compare product details around load range, sidewall styling, and intended road use.
Year(s): 2008|Fit(s): Mark LT|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, a 123/120R speed and load rating, a 3,415-pound maximum load at 80 psi, and a recommended rim width range of 7.5 to 9.5 inches. This size is specific to the Mark LT and suits owners who need the taller 18-inch fitment associated with truck-oriented use, while still confirming wheel width and service requirements before final selection.
Year(s): 2008|Fit(s): Navigator|Construction: Radial|Rim: 18-in rim
255/70R18 is a metric radial size with a 255-millimeter section width, a 70-series aspect ratio, and an 18-inch rim diameter. It is a Navigator-specific fitment rather than a shared size across the entire 2008 Lincoln Trucks family. Navigator owners should verify that their vehicle is on the 18-inch wheel package before moving forward, since the main choice here is correct model-and-wheel matching.
Three Lincoln Trucks models are covered for 2008: the MKX, Mark LT, and Navigator. They do not all use the same tire sizes, so identifying the exact model is the first step before comparing dimensions or products. Select your model below to narrow the fitment history and see the tire options that apply to that specific vehicle.
2008 Lincoln Trucks MKX
The 2008 Lincoln Trucks MKX was Lincoln’s car-based luxury crossover, aimed at buyers who wanted a quieter, more road-focused driving experience than a traditional truck-based SUV. Its tire fitments mount on either 18-inch or 20-inch wheels, depending on the wheel package, so confirming the wheel diameter is the key step before choosing a size.
The 2008 Lincoln Trucks Mark LT was Lincoln’s premium take on the full-size pickup, blending luxury trim with truck utility. Its fitments span 18-inch and 20-inch wheels, and the model carries more than one 18-inch size, so owners should confirm the exact wheel and tire package rather than relying on year and make alone.
The 2008 Lincoln Trucks Navigator remained Lincoln’s flagship full-size luxury SUV, known for its large footprint and upscale highway comfort. Its tires mount on either 18-inch or 20-inch wheels, with one size shared with the Mark LT and another unique to the Navigator, making wheel verification especially important.
One product is available across six tire sizes for 2008 Lincoln Trucks vehicles. The 275/65R18 fitment includes one BFGoodrich radial with an RWL sidewall, so confirm your exact size and wheel package before selecting a tire.
These FAQs sort out which sizes belong to the MKX, Mark LT, and Navigator, how to decode Lincoln’s 2008 metric tire sizing, and what to check for wheel fit, load needs, highway use, and long-term care on low-use luxury trucks and SUVs.
Size Basics & Fitment
What tire sizes fit 2008 Lincoln Trucks vehicles?
2008 Lincoln Trucks vehicles use six sizes across three models. The MKX uses 245/50R20 and 245/60R18, the Mark LT uses 275/55R20, 265/60R18, and 275/65R18, and the Navigator uses 255/70R18 and 275/55R20. Rim diameters across the range are either 18 inches or 20 inches, so the lineup does not share one universal fitment.
That means year and make alone are not enough to choose a tire for 2008 Lincoln Trucks vehicles. Start by confirming whether you have an MKX, Mark LT, or Navigator, then verify the wheel diameter actually on the vehicle. That step quickly separates the crossover-sized MKX fitments from the larger truck and SUV sizes used on the Mark LT and Navigator.
What does 245/50R20 mean on a 2008 Lincoln Trucks tire?
On a 2008 Lincoln Trucks tire, 245/50R20 is a metric radial size. The 245 is the nominal section width in millimeters, 50 is the aspect ratio, R identifies radial construction, and 20 is the wheel diameter in inches. Within the 2008 Lincoln Trucks range, that size applies to the MKX.
For an MKX owner, that code matters because it distinguishes the 20-inch wheel package from the model’s 18-inch alternative. It is not interchangeable with an 18-inch fitment without changing wheel diameter as well. When the vehicle has replacement wheels, compare the tire size on the sidewall with the wheel itself before moving on to tread choice or brand preference.
Do all 2008 Lincoln Trucks models use the same tire size?
No, 2008 Lincoln Trucks models do not all use the same tire size. The MKX has its own two sizes, the Mark LT has three sizes, and the Navigator has two sizes. Only 275/55R20 crosses between models, and it is shared by the Mark LT and Navigator rather than the full lineup.
That model split matters because a size that fits one 2008 Lincoln Trucks platform may be completely wrong for another. The MKX is a midsize crossover, while the Mark LT and Navigator are larger body-on-frame vehicles with different dimensional and load demands. Identifying the model first prevents confusion and narrows the search much faster.
Buying the Right Tire
What sidewall styles are available for 2008 Lincoln Trucks tires?
Sidewall style detail is confirmed here for the 275/65R18 used on the 2008 Lincoln Trucks Mark LT, where BFGoodrich offers an RWL, or raised white letter, sidewall. That look is more assertive and truck-oriented than a plain blackwall treatment and suits a size often associated with pickup use.
For 2008 Lincoln Trucks owners, sidewall appearance is part of the personality of the vehicle as much as the raw dimensions. A Mark LT wearing an RWL tire presents a more rugged visual style, while a luxury-oriented SUV or crossover owner may prefer a cleaner sidewall when that option exists in the correct size. Matching appearance to the vehicle’s character is worth considering once fitment is settled.
What brands make tires for 2008 Lincoln Trucks vehicles?
BFGoodrich is confirmed in the 275/65R18 fitment for 2008 Lincoln Trucks vehicles, specifically for the Mark LT. That product is the All-Terrain T/A KO2, a radial truck tire with a raised white letter sidewall and a heavy-duty service rating suited to full-size pickup use.
Brand selection can vary by exact size, so the practical move is to start with the correct tire code before comparing names. A 2008 Lincoln Trucks owner choosing for an MKX may end up in a very different category than someone outfitting a Mark LT for truck duty. Once the size is right, compare sidewall look, service rating, and intended driving style within that fitment.
What is the difference between the BFGoodrich All-Terrain T/A KO2 and other tire types for the 2008 Lincoln Trucks Mark LT?
For the 2008 Lincoln Trucks Mark LT, the BFGoodrich All-Terrain T/A KO2 appears in 275/65R18 with radial construction, an RWL sidewall, a 123/120R rating, a 3,415-pound maximum load at 80 psi, and a rim width range of 7.5 to 9.5 inches. Those specifications place it firmly in the truck-service category rather than a lower-profile crossover or highway-luxury fitment.
That distinction matters because the Mark LT spans more than one size and wheel package. A buyer choosing 275/65R18 is usually prioritizing the dimensions and service character tied to that taller 18-inch truck fitment, not just appearance. Before choosing any alternative in a different size, confirm whether the vehicle is meant to stay on its present wheel package or return to a factory-equivalent setup.
Fitting & Setup
What rim width do 2008 Lincoln Trucks tires require?
A confirmed rim width range is available for one 2008 Lincoln Trucks size: the 275/65R18 used on the Mark LT fits rims from 7.5 to 9.5 inches wide. That same tire mounts on an 18-inch rim and carries a truck-rated load capacity suited to a full-size pickup application.
Rim width matters because even when the diameter is correct, the wheel still needs to support the tire’s approved profile. If your 2008 Lincoln Trucks Mark LT has aftermarket wheels, verify both diameter and width before choosing 275/65R18. That check is especially important on trucks that may have had wheel changes for appearance or off-road style.
Do 2008 Lincoln Trucks tires require inner tubes?
The 2008 Lincoln Trucks sizes covered here are all modern radial formats, and no tube-type marking is identified in the confirmed product information for the 275/65R18 Mark LT fitment. That points buyers toward modern tubeless-style fitment rather than the tube-type practice associated with much older collector vehicles.
Even so, wheel condition still matters. On any 2008 Lincoln Trucks vehicle, inspect the wheels for bead-seat corrosion, bent flanges, and valve-stem condition before mounting new tires. If the vehicle has been sitting for long periods or has older aftermarket wheels, a careful wheel inspection is just as important as selecting the correct size.
Maintenance, Storage & Longevity
How should I store a 2008 Lincoln Trucks when the tires are fitted?
A 2008 Lincoln Trucks vehicle should be stored out of direct sunlight, away from electric motors, chargers, welders, and other ozone-producing equipment, and on a clean, dry surface. Keep the tires properly inflated and move the vehicle periodically so one part of the tread does not carry the full weight for months at a time.
Those steps help preserve both appearance and ride quality, especially on luxury trucks and SUVs that may spend long periods parked between drives. If the vehicle will be stored for a season, washing road grime from the tires and checking pressure before storage pays off later. Long static storage is harder on tires than many owners realize.
How long do tires on a 2008 Lincoln Trucks typically last?
On a 2008 Lincoln Trucks vehicle, tire age often matters more than mileage because many luxury SUVs and collector-kept trucks are driven infrequently. A sensible rule is to begin close inspection around five to seven years of age and to treat ten years as the point where replacement deserves serious consideration, regardless of remaining tread depth.
Check the DOT date code on each tire sidewall and do not judge condition by appearance alone. A tire can look presentable yet still be aged internally from heat cycles, time, and storage conditions. If a 2008 Lincoln Trucks vehicle still rides on older rubber, replacement may improve peace of mind even before obvious wear becomes visible.
How often should tires on a 2008 Lincoln Trucks be inspected?
Tires on a 2008 Lincoln Trucks vehicle should be inspected before every drive and again before any longer highway outing. Look for cracking, punctures, sidewall bulges, uneven wear, embedded debris, and pressure loss, and make sure the spare is in equally usable condition.
That routine is especially important on heavier vehicles such as the Mark LT and Navigator, where tire condition has a direct effect on steering response and load carrying. A quick visual check takes only a minute and can catch problems before they turn into a roadside issue. If the truck or SUV has been parked for weeks, inspect even more carefully.
Restoration & Authenticity
What tires were originally fitted to the 2008 Lincoln Trucks MKX?
The 2008 Lincoln Trucks MKX used modern radial tires, with 245/50R20 and 245/60R18 fitting the model depending on wheel package. By 2008, radial construction was standard industry practice for mainstream luxury crossovers, so authenticity at this age centers more on keeping the correct size and wheel-package relationship than on choosing an older-style construction.
Owners returning an MKX to factory-style presentation should verify the original wheel and tire combination on the vehicle itself, then match the replacement size accordingly. Dealer literature, original window stickers, and marque forums can help sort out package-specific details. That approach is more useful here than chasing a period-correct construction difference that did not exist in the same way on older vehicles.
Does correct tire fitment matter for showing a 2008 Lincoln Trucks?
Yes, correct tire fitment still matters when showing a 2008 Lincoln Trucks vehicle, even though a 2008 model is newer than the traditional concours era. Judges and knowledgeable enthusiasts often notice whether the size matches the vehicle’s wheel package and overall stance, especially on luxury models where appearance and proportion are part of the design.
For a 2008 Lincoln Trucks MKX, Mark LT, or Navigator, the most visible errors are usually incorrect diameter, an obviously wrong profile, or a sidewall style that clashes with the vehicle’s character. Keeping the proper size for the model and wheel package is the first priority. Event-specific standards can vary, so local clubs and model-specific communities remain valuable references.
What is the difference between 275/55R20 and 275/65R18 for the 2008 Lincoln Trucks Mark LT?
For the 2008 Lincoln Trucks Mark LT, 275/55R20 and 275/65R18 are both radial sizes, but they mount on different wheel diameters and reflect different overall fitment packages. The 275/55R20 is shared with the Navigator and fits a 20-inch wheel, while the 275/65R18 fits an 18-inch wheel and appears here in a BFGoodrich truck tire rated at 3,415 pounds at 80 psi.
That makes the choice more about preserving the truck’s intended wheel-and-tire package than substituting one size for another casually. If the truck is being returned to a factory-style look, confirm which wheel diameter it originally carried and keep the corresponding tire size. The visual stance and service character of the truck can change noticeably when moving between those two fitments.
Safety & Road Use
Are 2008 Lincoln Trucks tires safe for highway driving?
Yes, 2008 Lincoln Trucks tires can be appropriate for highway driving when the correct size, load rating, and inflation are matched to the vehicle. The confirmed 275/65R18 BFGoodrich fitment for the Mark LT carries an R speed rating, which corresponds to 106 mph, along with a heavy-duty 123/120 load index for truck service.
Real-world safety still depends on more than the tire alone. A 2008 Lincoln Trucks vehicle also relies on suspension condition, brake health, alignment, and tire age, especially on larger and heavier models such as the Navigator and Mark LT. If the vehicle has been parked for extended periods, inspect the tires closely before trusting them on a sustained highway run.
What inflation pressure should I use for 2008 Lincoln Trucks tires?
Inflation pressure on 2008 Lincoln Trucks tires should follow the vehicle manufacturer’s placard for normal use, while the tire’s own sidewall marks the pressure associated with its maximum rated load. For the 275/65R18 Mark LT fitment confirmed here, the tire carries 3,415 pounds at 80 psi, which is a load-capacity reference rather than a one-pressure-fits-all everyday setting.
That distinction matters because tire maximum pressure and vehicle operating pressure are not automatically the same thing. Use the original door-jamb or owner’s manual recommendation as the baseline for the correct size on your exact model, then confirm that the tire you choose is appropriate for that application. Do not transfer one size’s pressure assumptions to another Lincoln Trucks fitment.
What should I check before taking a 2008 Lincoln Trucks on a longer drive?
Before taking a 2008 Lincoln Trucks vehicle on a longer drive, inspect all five tires for cracking, cuts, bulges, punctures, and uneven wear, and verify cold inflation pressure. Make sure the valve stems are in good shape and check the spare’s condition as carefully as the four tires on the ground.
A longer trip is also a good time to think beyond the tires. A 2008 Lincoln Trucks MKX, Mark LT, or Navigator benefits from a broader age-related check that includes brakes, steering, suspension, and fluid levels, since tire performance is only as trustworthy as the chassis supporting it. A few minutes in the garage can prevent a much larger problem on the road.
