2020 Lincoln Trucks Tire Fitment Guide

2020 Lincoln Trucks vehicles use 12 sizes across 4 models. Aviator uses 255/60R19, 255/55R20, 275/45R21, and 275/40R22; Corsair uses 225/60R18, 225/55R19, and 245/45R20; Nautilus uses 245/60R18, 245/50R20, and 265/40R21; Navigator uses 275/55R20 and 285/45R22. Rim diameters therefore range from 18 to 22 inches across the lineup, and the only confirmed rim-width range here is for 245/45R20, which fits 7.5- to 9.0-inch-wide rims.

That spread means year and make alone are not enough for accurate tire selection on 2020 Lincoln Trucks. Start by identifying whether you have an Aviator, Corsair, Nautilus, or Navigator, then verify the wheel diameter already on the vehicle. If the SUV may have been upgraded, downsized for winter use, or fitted with takeoff wheels, read the size molded into the current sidewall before moving to any tire choice.

On a 2020 Lincoln Trucks tire, 245/45R20 is a modern metric radial size. The 245 is the nominal section width in millimeters, 45 is the aspect ratio, meaning the sidewall height is 45 percent of the section width, R indicates radial construction, and 20 is the wheel diameter in inches. Within this year and make, that exact size belongs to the Corsair.

Knowing how to read that code helps you avoid choosing by wheel diameter alone. A 20-inch Lincoln wheel can still require very different tire widths and profiles depending on the model, so a 245/45R20 Corsair tire is not interchangeable with 255/55R20 Aviator, 245/50R20 Nautilus, or 275/55R20 Navigator fitments. Match the full code, not just the final number.

No, 2020 Lincoln Trucks models do not use the same tire size. Every size shown here is model-specific: the Aviator has four sizes, the Corsair has three, the Nautilus has three, and the Navigator has two. Even when two models share the same wheel diameter, they still use different metric sizes with different section widths and aspect ratios.

That matters because luxury SUVs from the same brand can look similar at a glance while requiring very different tire dimensions. If you are starting from a registration card or insurance paperwork that only confirms year and make, identify the model before comparing tires. That step narrows the search immediately and prevents cross-shopping among sizes that fit a different Lincoln entirely.

The covered 2020 Lincoln Trucks product range here shows blackwall sidewalls in the 245/45R20 Corsair size. No whitewall or specialty sidewall treatment appears in the represented product mix for that fitment. That aligns with the late-model luxury-SUV market, where blackwall tires are the normal visual choice rather than a restoration-style feature.

For most 2020 Lincoln Trucks owners, sidewall choice is less about historical authenticity and more about keeping the appearance consistent with modern factory-era styling. If your Corsair uses 245/45R20, you can focus on brand, speed rating, and wheel-width compatibility without needing to sort through multiple sidewall themes. Owners of the other sizes should confirm the exact product styling once they narrow to the correct fitment.

Within the represented 2020 Lincoln Trucks product range, the 245/45R20 Corsair fitment is available from BFGoodrich and Nitto. BFGoodrich appears in multiple g-Force-family offerings, while Nitto appears with the NT555 G2. All of those products are radial blackwall tires aimed at modern road use rather than vintage-style presentation.

Brand choice comes after you confirm the exact Lincoln model and tire size. If your Corsair runs 245/45R20, you can compare BFGoodrich and Nitto by speed rating, weight, and wheel-width suitability. If your Lincoln uses one of the other 11 sizes, the first step is to move into that specific size or model page and confirm which products exist for that exact application.

For the 2020 Lincoln Trucks 245/45R20 size, BFGoodrich appears with multiple products and Nitto appears with the NT555 G2. The BFGoodrich options include W- and Y-speed-rated versions, with recorded weights around 30 to 30.73 pounds and a confirmed 7.5- to 9.0-inch rim-width range on the examples that publish it. The Nitto NT555 G2 in the same size is W-rated and carries a recorded weight of 30.38 pounds.

That means the comparison is less about basic fitment and more about the specific product character within the same size. A Corsair owner choosing 245/45R20 should compare speed rating first if that matters, then look at wheel-width compatibility and the overall tire category within each brand’s lineup. Keeping the comparison inside the exact same size prevents confusion with other 20-inch Lincoln fitments that use different dimensions.

A confirmed rim-width range appears here for the 2020 Lincoln Trucks 245/45R20 Corsair size: 7.5 to 9.0 inches. The recorded products in that size share that same basic wheel-width window where published. Other 2020 Lincoln Trucks sizes shown here do not carry a published rim-width range in this set of products.

Rim width matters because the same tire size can behave differently if mounted outside its intended wheel range. If your Corsair uses 245/45R20, measure or verify the wheel before choosing among products. For Aviator, Nautilus, and Navigator sizes, confirm the original wheel specification or the actual wheel on the vehicle before treating any tire as a match.

The represented 2020 Lincoln Trucks 245/45R20 products are tubeless radial tires. One BFGoodrich product includes a TL marking, and the other products in that same size follow modern tubeless radial practice as well. No tube-type product appears in the covered 245/45R20 group.

For a modern Lincoln SUV with original-style late-model wheels, tubeless construction is the normal expectation. Even so, it is smart to check the sidewall marking on the exact tire you choose and to inspect the wheel condition, valve stems, and bead seats during installation. That matters more on vehicles that may have had wheel changes or cosmetic refinishing over time.

A 2020 Lincoln Trucks vehicle should be stored in a cool, dry, dark space away from direct sunlight, electric motors, welders, battery chargers, and other ozone-producing equipment. Keep the tires clean, maintain inflation, and move the vehicle periodically so one section of tread is not carrying the load for months at a time. Because every size here is radial, flat-spotting risk is generally lower than with older bias-ply designs, but long static storage can still affect ride quality and casing condition.

Good storage habits preserve both appearance and drivability on a modern luxury SUV that may see seasonal or hobby use. If the vehicle will sit for a long period, many owners either move it regularly or use stands in a way that follows the vehicle manufacturer’s lifting guidance. Before putting the vehicle back into service, check pressures and give each tire a close visual inspection.

On a 2020 Lincoln Trucks vehicle, tire age usually matters more than mileage once the SUV becomes a low-use collector or second vehicle. A good rule is to begin careful age-based evaluation around five to seven years and to treat roughly ten years as a point where replacement deserves serious consideration regardless of remaining tread. The DOT date code on the sidewall tells you when each tire was made.

That approach is especially important on luxury SUVs that may appear lightly used while spending long periods parked. Rubber hardens with time, and visual tread depth alone does not tell the full story. If a 2020 Lincoln Trucks vehicle still wears older original-era tires, inspect for cracking, hardening, vibration, or pressure loss and use those signs along with age to plan replacement.

Tires on a 2020 Lincoln Trucks vehicle should be inspected before every drive, with a more thorough check before any longer trip. Look for pressure loss, punctures, sidewall cracking, uneven wear, cuts, bulges, and any sign that a tire has been run low. On a modern tubeless setup, valve stems and wheel sealing surfaces also deserve attention.

Frequent inspection matters because even a refined late-model SUV can develop tire issues while parked, especially if temperatures change or the vehicle sits for weeks at a time. A quick walkaround catches obvious problems, while a hands-on check before highway travel gives you time to address them before they become a roadside interruption. Include the spare in that routine if the vehicle still carries one.

Yes, 2020 Lincoln Trucks tires in the represented 245/45R20 product range are built for modern highway use, and the speed ratings shown are W and Y. W-rated tires carry a ceiling of 168 mph, while Y-rated tires are rated for 186 mph and above under their standardized test conditions. Those ratings are far beyond ordinary U.S. highway speeds and fit the expectations of a modern radial SUV tire.

Real-world safety still depends on more than the speed symbol on the sidewall. Tire age, inflation, alignment, load, road condition, and the mechanical condition of the SUV all matter before a longer trip. For a 2020 Lincoln Trucks vehicle, highway confidence comes from matching the exact size, inspecting the tire carefully, and keeping the entire vehicle in proper operating condition.

Inflation pressure for 2020 Lincoln Trucks tires should start with the vehicle manufacturer’s placard or owner’s manual for the exact model and size. Within the represented 245/45R20 products, one BFGoodrich tire carries a maximum load figure of 1,930 pounds at 50 psi, and another shows 1,929 pounds at 50 psi. That number is the tire’s rated maximum condition, not a universal operating pressure for every 2020 Lincoln Trucks application.

The practical rule is to avoid transferring a pressure figure from one size or product to another. Use the Lincoln recommendation for normal service, then confirm that the tire’s own load and pressure limits are appropriate for the vehicle. If the vehicle has been fitted with a different wheel-and-tire package than stock, that is the point where careful fitment review becomes especially important.

Before taking a 2020 Lincoln Trucks vehicle on a longer drive, inspect each tire for cracking, cuts, bulges, punctures, abnormal wear, and correct cold inflation pressure. Check that the valve stems are in good condition, verify that the tread is wearing evenly, and inspect the spare if one is present. A quick look at the inside sidewall area is also worthwhile if the wheel design allows it.

That tire check should be part of a broader pre-drive review on any vehicle, even one as modern as a 2020 Lincoln. Confirm brakes, fluids, battery condition, and lighting, especially if the SUV has been parked for an extended period. Catching a weak tire, low pressure, or aging spare before departure is far easier than dealing with it once the trip is underway.
