In 2005, Lincoln Trucks blended luxury SUV comfort with truck-based capability, giving buyers a more upscale take on the American sport-utility formula. The Aviator and Navigator served different roles within the lineup, and that difference carries directly into tire choice. Across 2005 Lincoln Trucks models, three tire sizes appear, with the Aviator using one 17-inch radial size and the Navigator using two 18-inch radial sizes rather than sharing one fitment across the range. That means the first step is to confirm whether you have an Aviator or a Navigator, then verify which of the Navigator’s two sizes belongs on your wheels before choosing a tire.
Which Tire Size Is Right for Your 2005 Lincoln Trucks
Three tire sizes cover 2005 Lincoln Trucks vehicles, and they vary by model rather than being shared across the full range. The key decision is confirming the correct model and rim diameter first, since the Aviator uses a 17-inch tire while the Navigator uses 18-inch sizes. Understanding that distinction before choosing a product saves time and helps match the tire to the right vehicle.
Year(s): 2005|Fit(s): Aviator|Construction: Radial|Rim: 17 in
The 245/65R17 is a metric radial size with a 245-millimeter section width, a 65-series aspect ratio, and a 17-inch rim diameter. For this size, BFGoodrich is available with an RWL sidewall style, and the tire carries an S speed rating with a 112 mph ceiling. This size is specific to the 2005 Lincoln Trucks Aviator rather than the full model range, so Aviator owners should stay focused on the 17-inch fitment that matches their wheels.
Year(s): 2005|Fit(s): Navigator|Construction: Radial|Rim: 18-in rim
The 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 size within the 2005 Lincoln Trucks lineup, and the main fitment point is confirming that your Navigator is set up for the narrower 18-inch option rather than the 275 section width. This is the size to follow when your vehicle and wheel package call for the 255/70R18 specification.
Year(s): 2005|Fit(s): Navigator|Construction: Radial|Rim: 18 in
The 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 style, and the tire carries an R speed rating. This size is specific to certain 2005 Lincoln Trucks Navigator applications, so Navigator owners should confirm the wheel and size already on the vehicle before moving to this wider 18-inch fitment.
Two Lincoln Trucks models are covered for 2005, and they do not share the same tire sizes across the lineup. The Aviator uses its own 17-inch fitment, while the Navigator uses two 18-inch sizes, so identifying the model is essential before narrowing down tire options. Select a model below for model-specific fitment history and products.
2005 Lincoln Trucks Aviator
The 2005 Lincoln Trucks Aviator was Lincoln’s mid-size luxury SUV, aimed at buyers who wanted premium appointments in a more manageable package than a full-size utility. Its tire fitment mounts on 17-inch wheels, separating it clearly from the larger Navigator and making model identification the first step in getting the right replacement.
The 2005 Lincoln Trucks Navigator was Lincoln’s flagship full-size SUV, known for its larger footprint, upscale trim, and strong presence in the luxury truck market. Its tires mount on 18-inch wheels, and two different 18-inch sizes appear within the model range, so Navigator owners need to confirm the exact size already fitted to the vehicle or wheel package.
Two products are available across three tire sizes for 2005 Lincoln Trucks vehicles. The 245/65R17 has one BFGoodrich radial with an RWL sidewall, and the 275/65R18 has one BFGoodrich radial with an RWL sidewall.
These answers cover how 2005 Lincoln Trucks tire fitment changes between Aviator and Navigator models, what the metric size codes mean, how 17-inch and 18-inch applications differ, and what to watch for when maintaining a luxury SUV that may see low annual mileage.
Size Basics & Fitment
What tire sizes fit 2005 Lincoln Trucks vehicles?
Three tire sizes fit 2005 Lincoln Trucks vehicles, and they are split by model. The Aviator uses 245/65R17 on a 17-inch rim. The Navigator uses 255/70R18 or 275/65R18 on an 18-inch rim. Where product fitment details are available, the 245/65R17 works with 7.0- to 8.0-inch rim widths, while the 275/65R18 works with 7.5- to 9.5-inch rim widths.
That means year and make alone are not enough for a confident selection. Start by confirming whether you have an Aviator or a Navigator, then check the size already on the tire sidewall or the vehicle placard. If you have a Navigator, do not assume that both 18-inch sizes interchange without checking the wheel and original fitment for your specific vehicle.
What does 245/65R17 mean on a 2005 Lincoln Trucks tire?
On a 2005 Lincoln Trucks tire, 245/65R17 is a metric radial size. The 245 is the section width in millimeters, 65 is the aspect ratio, R means radial construction, and 17 is the wheel diameter in inches. On the 2005 Lincoln Trucks range, this size belongs to the Aviator and mounts on a 17-inch wheel.
For an owner, that code matters because each part affects fitment. A 17-inch wheel is mandatory for this size, and the 245 width and 65-series profile help define the tire’s overall dimensions. If your Aviator is still on its original wheel diameter, this size is the correct place to begin before comparing sidewall styling, load capacity, or brand preference.
Do all 2005 Lincoln Trucks models use the same tire size?
No, 2005 Lincoln Trucks models do not use the same tire size. The Aviator uses 245/65R17, while the Navigator uses either 255/70R18 or 275/65R18. The difference is more than width alone, because the Aviator and Navigator also use different rim diameters: 17 inches for the Aviator and 18 inches for the Navigator.
That split reflects the different roles of the two SUVs. The Aviator was the smaller, more maneuverable luxury utility, while the Navigator occupied the full-size flagship position. From a tire-buying standpoint, identifying the model first prevents the most common mistake on a year-make page: choosing a tire that matches the badge but not the wheel diameter or application.
Buying the Right Tire
What sidewall styles are available for 2005 Lincoln Trucks tires?
For 2005 Lincoln Trucks tires with product coverage here, the available sidewall style is RWL, or raised white letters. That appears on the BFGoodrich options in both 245/65R17 for the Aviator and 275/65R18 for the Navigator. RWL gives these SUVs a more truck-oriented, utility-forward appearance than a plain blackwall would.
Appearance matters more on a luxury SUV than many buyers expect, especially when the vehicle sits at the intersection of upscale trim and truck hardware. If you want a more assertive period look, raised white letters can suit the era well. If your goal is a quieter visual presentation, confirm the exact sidewall treatment on the product you are considering before matching it to the character of your vehicle.
What brands make tires for 2005 Lincoln Trucks vehicles?
BFGoodrich covers the available 2005 Lincoln Trucks tire products here. It appears in 245/65R17 for the Aviator and in 275/65R18 for the Navigator, both in the All-Terrain T/A KO2 line. That gives owners a recognizable American performance-and-truck brand with a long history in the replacement tire market.
Brand choice still has to follow size choice. An Aviator owner should stay within the 245/65R17 fitment, while a Navigator owner needs to confirm whether the vehicle uses 255/70R18 or 275/65R18 before narrowing the field further. Once the correct size is settled, compare load, speed rating, sidewall appearance, and intended use rather than choosing by brand name alone.
What is the difference between BFGoodrich All-Terrain T/A KO2 options for 2005 Lincoln Trucks?
The BFGoodrich All-Terrain T/A KO2 appears in more than one 2005 Lincoln Trucks size, and the specs change with the fitment. The 245/65R17 version for the Aviator carries a 2,405-pound maximum load at 65 psi, fits 7.0- to 8.0-inch rims, weighs 44 pounds, and has a 111S service description. The 275/65R18 version for the Navigator carries a 3,415-pound maximum load at 80 psi, fits 7.5- to 9.5-inch rims, weighs 57 pounds, and has a 123/120R service description.
Those differences show why the same tire line should not be treated as interchangeable across the 2005 Lincoln Trucks range. The larger Navigator application is built around a heavier-duty spec with greater load capability and a different wheel-width range. Choose by the exact size and service description your vehicle requires, then confirm that the wheel dimensions on the vehicle align with the tire’s approved range.
Fitting & Setup
What rim width do 2005 Lincoln Trucks tires require?
Rim-width guidance is available for two 2005 Lincoln Trucks sizes. The 245/65R17 used on the Aviator fits 7.0- to 8.0-inch rims, while the 275/65R18 used on the Navigator fits 7.5- to 9.5-inch rims. Both sizes also require the correct rim diameter: 17 inches for the Aviator fitment and 18 inches for the wider Navigator fitment.
Rim width matters because it affects section shape, tread profile, and the way the tire sits on the wheel. Even when the sidewall code matches, a tire mounted outside its approved wheel-width range can behave differently than intended. Before choosing a replacement, compare the wheel on the vehicle with the tire’s approved range and avoid assuming all factory-looking wheels share the same width.
Do 2005 Lincoln Trucks tires require inner tubes?
The available 2005 Lincoln Trucks tire products here are radial truck and SUV tires without tube-type markings. That points toward tubeless fitment rather than inner-tube use for the covered sizes. Nothing in these fitments suggests the tube-type collector-tire setup more common on much older vehicles.
Tubeless tires still depend on the condition of the wheel, valve stem, and bead area. If a wheel has corrosion, damage, or a questionable seal surface, address that before mounting new tires. Owners working with aftermarket wheels or previously repaired rims should verify compatibility carefully so the tire, wheel, and valve hardware all work together as a proper tubeless assembly.
Maintenance, Storage & Longevity
How should I store a 2005 Lincoln Trucks when the tires are fitted?
A 2005 Lincoln Trucks vehicle should be stored in a cool, dry, shaded space with the tires protected from direct sunlight, electric motors, welders, battery chargers, and other ozone-producing equipment. Keep the vehicle on clean pavement or a barrier surface rather than bare dirt, and maintain normal operating inflation so the casing is not left under-supported during long storage periods.
Even though these are radial tires rather than older bias-ply designs, long static storage still invites flat spotting, sidewall aging, and pressure loss. Rolling the vehicle periodically helps, and very long storage intervals may justify using stands in a way that follows safe lifting practice. If your Lincoln is a low-mile collector SUV, careful storage can preserve both appearance and road manners between outings.
How long do tires on a 2005 Lincoln Trucks typically last?
Tires on a 2005 Lincoln Trucks vehicle should be judged by age as much as by tread depth. A good rule is to begin close evaluation around five to seven years of service and to treat about ten years as the point where replacement deserves serious consideration, even if the vehicle has low mileage. The DOT date code on the tire sidewall is the best way to establish age.
That matters especially for luxury SUVs that may be driven only occasionally. A tire can look usable in the garage yet still age out because of heat cycles, ozone exposure, and time. If your Lincoln sees seasonal or weekend use, keep a record of installation dates and inspect for hardening, cracking, and irregular wear instead of relying on mileage alone.
How often should tires on a 2005 Lincoln Trucks be inspected?
Tires on a 2005 Lincoln Trucks vehicle should be inspected before every drive and again before any longer highway outing. Look for pressure loss, sidewall cracking, cuts, punctures, bulges, uneven tread wear, and signs of impact damage from curbs or road hazards. Because these SUVs are heavier than passenger sedans, small tire issues can show up quickly in ride quality and steering feel.
Regular inspection is one of the simplest ways to protect an older luxury SUV that may alternate between long idle periods and family-road-trip duty. Include the spare in the same routine, since a neglected spare often fails when finally called into service. If anything looks questionable, have the tire and wheel checked before the next drive rather than waiting for a visible failure.
Restoration & Authenticity
What tires were originally fitted to the 2005 Lincoln Trucks Aviator?
A 2005 Lincoln Trucks Aviator came from a period when radial tires were standard equipment across mainstream luxury SUVs, so radial construction is the correct starting point for authenticity. Within this year-make range, the Aviator uses 245/65R17, which places it on a 17-inch wheel. That makes the construction question straightforward compared with older collector vehicles that straddle bias-ply and radial eras.
For restoration-minded owners, the main authenticity points are the correct size, wheel diameter, and an appearance that suits a mid-2000s premium SUV. If your goal is factory-style presentation, verify the original placard information and wheel package on the vehicle itself. A Lincoln or Ford marque specialist can also help confirm market-specific details if the vehicle has had wheels or trim changed over time.
Does correct tire fitment matter for showing a 2005 Lincoln Trucks?
Correct tire fitment does matter when showing a 2005 Lincoln Trucks vehicle, even though it comes from a newer collector era than prewar or muscle-car applications. Judges and knowledgeable enthusiasts will notice the correct size, proper wheel diameter, and whether the overall look fits the vehicle’s original luxury-SUV character. An incorrect 17-inch-versus-18-inch fitment would stand out immediately on this year and make.
For a clean presentation, match the tire size to the exact model and wheel package first, then consider sidewall appearance. Raised white letters can create a more assertive truck look, while some owners may prefer a subtler visual treatment depending on the event and restoration goal. If the vehicle is headed for marque judging, confirm the event’s expectations before finalizing a tire style.
What is the difference between the Aviator and Navigator tire fitments on 2005 Lincoln Trucks?
The difference between the Aviator and Navigator tire fitments on 2005 Lincoln Trucks starts with wheel diameter and vehicle class. The Aviator uses 245/65R17 on a 17-inch wheel, while the Navigator uses 255/70R18 or 275/65R18 on 18-inch wheels. That reflects the Aviator’s mid-size role and the Navigator’s larger, heavier full-size luxury SUV position.
From an authenticity standpoint, keeping the proper model-specific fitment preserves the stance and visual balance Lincoln intended. Swapping between those fitments without a clear wheel-package reason can alter both appearance and correctness. Owners restoring one of these vehicles to factory character should begin with the original size category for the model before considering any cosmetic or use-based preferences.
Safety & Road Use
Are 2005 Lincoln Trucks tires safe for highway driving?
Yes, 2005 Lincoln Trucks tires can be appropriate for highway driving when the tire is the correct size, in sound condition, and operated within its service rating. The available 245/65R17 example carries an S speed rating, which corresponds to 112 mph. The available 275/65R18 example carries an R speed rating. For normal U.S. highway use, those limits are well above typical legal cruising speeds.
Tire condition matters as much as the rating itself. Age, inflation, alignment, and load all affect real-world safety, especially on a large SUV. A 2005 Lincoln Trucks vehicle also depends on the health of its suspension, brakes, and steering system, so view the tire as one part of the package. If the vehicle has sat for long stretches, inspect everything carefully before trusting it on a longer trip.
What inflation pressure should I use for 2005 Lincoln Trucks tires?
Inflation pressure for 2005 Lincoln Trucks tires should follow the vehicle placard or owner’s manual for normal service, while the tire’s maximum sidewall figure indicates the tire’s load-carrying ceiling rather than the everyday operating target. Among the available examples, the 245/65R17 carries 2,405 pounds at 65 psi and the 275/65R18 carries 3,415 pounds at 80 psi. Those figures should not be transferred from one size to another.
Use the factory recommendation for your exact model and wheel package as the baseline, then compare it with the tire maker’s guidance if you are using a specialty replacement. Pressure affects ride, tread wear, and stability, particularly on a tall SUV. Check pressures cold, recheck them after seasonal temperature swings, and avoid assuming that a heavier-duty tire should automatically be run at its maximum printed pressure.
What should I check before taking a 2005 Lincoln Trucks on a longer drive?
Before taking a 2005 Lincoln Trucks vehicle on a longer drive, inspect each tire for cracking, cuts, punctures, bulges, uneven wear, and correct cold inflation. Check that the valve stems are in good condition, confirm the spare is inflated and usable, and make sure the wheel lug hardware is secure. On an older luxury SUV, the tires should be part of a broader mechanical check that includes brakes, steering, and suspension.
Longer drives expose small problems that short around-town trips may hide. A slightly aging tire, a slow leak, or a worn suspension component can become much more obvious at highway speed or with passengers and cargo on board. Spending a few minutes on a full pre-trip walkaround is especially worthwhile on a 2005 Lincoln Trucks vehicle that may alternate between daily use and long periods of inactivity.
