The 2020 Nissan Trucks Armada is a full-size SUV built for buyers who want traditional body-on-frame strength, three-row space, and a substantial road presence. In this model year, tire selection centers on trim-specific radial fitment rather than a single universal size, with 265/70R18, 275/60R20, and 275/50R22 all used across the Armada lineup. That means the first step is matching the tire to the exact sub-model and wheel diameter. From there, the choice becomes more practical: maintaining the intended stance, selecting the right modern metric radial format, and confirming that the wheel and tire setup on the vehicle still matches its current configuration.
Which Tire Size Is Right for The 2020 Nissan Trucks Armada
The 2020 Nissan Trucks Armada uses three primary tire sizes, and the correct one depends on the exact sub-model and wheel diameter. Since these fitments span 18-inch, 20-inch, and 22-inch rims, the most important first step is confirming which wheels are on the vehicle now before comparing tread designs, brand choices, or replacement priorities.
A 275/50R22 tire uses a 275-millimeter nominal section width, a 50-series aspect ratio, radial construction, and a 22-inch rim diameter. On the 2020 Nissan Trucks Armada, this is the large-diameter modern metric radial fitment used on specific upper trims, giving the vehicle its most aggressive wheel-and-tire presentation within the factory size group. The lower profile compared with the Armada's other fitments makes wheel confirmation especially important when replacing worn tires. This size is the right place to start if the SUV is equipped with 22-inch wheels and the goal is to preserve its existing stance and fitment balance.
A 275/60R20 tire carries the same 275-millimeter nominal width as the 22-inch option, but it uses a taller 60-series sidewall on a 20-inch rim. For the 2020 Nissan Trucks Armada, this radial size serves as a trim-specific primary fitment and sits between the 18-inch and 22-inch combinations in wheel diameter and sidewall profile. Its overall dimensions keep it squarely in the full-size SUV range while retaining a substantial sidewall. This size deserves consideration when the Armada already has 20-inch wheels and the owner wants to stay with the proper trim-based fitment.
A 265/70R18 tire uses a 265-millimeter nominal section width, a 70-series profile, radial construction, and an 18-inch rim. On the 2020 Nissan Trucks Armada, this size belongs to the 18-inch wheel configuration and has the tallest sidewall of the three primary fitments used across the model range. That makes it visually and functionally distinct from the 20-inch and 22-inch setups, even though all three remain close in overall diameter. This is the correct size to evaluate when the vehicle is equipped with 18-inch wheels and the aim is to maintain the proper fitment for that configuration.
Tire fitment on the 2020 Nissan Trucks Armada varies by sub-model, so the exact trim matters before any replacement choice is made. Because the Armada uses three different rim diameters across the lineup, confirming both trim level and current wheel size helps prevent choosing the wrong tire format.

2020 Nissan Trucks Armada Platinum
The 2020 Nissan Trucks Armada Platinum can use either the 275/50R22 or 275/60R20 radial size, so this trim requires especially careful wheel confirmation. Tire selection starts with identifying whether the vehicle is on 22-inch or 20-inch rims, then matching the replacement tire to that setup.
The 2020 Nissan Trucks Armada Platinum Reserve uses the 275/50R22 radial size. For this sub-model, the main replacement decision is less about multiple fitments and more about preserving the existing 22-inch wheel setup and choosing a tire that matches the vehicle's intended stance.
The 2020 Nissan Trucks Armada SL uses the 275/60R20 radial size. That makes tire selection relatively straightforward as long as the vehicle still carries its 20-inch wheels and has not been changed to an aftermarket wheel-and-tire package.
The 2020 Nissan Trucks Armada SV uses the 265/70R18 radial size. For this sub-model, the practical focus is confirming the 18-inch wheel setup and replacing the tires with the same metric radial size unless the vehicle has been modified.
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.
Frequently Asked Questions
Common Armada tire questions at this level usually come down to trim-specific sizing, wheel diameter, modern metric radial fitment, and what to inspect before putting a full-size SUV back on the road. The FAQs below focus on exact 2020 Nissan Trucks Armada fitment decisions rather than general SUV tire advice.
Tire Size & Fitment
What tire size fits a 2020 Nissan Trucks Armada?
The 2020 Nissan Trucks Armada uses three primary tire sizes: 275/50R22, 275/60R20, and 265/70R18. The correct size depends on the exact sub-model and wheel package, so there is not one universal tire size for every Armada in this model year.
Platinum models can use either 275/50R22 or 275/60R20, Platinum Reserve uses 275/50R22, SL uses 275/60R20, and SV uses 265/70R18. Before replacing tires, confirm the trim and physically verify the wheel diameter on the vehicle, especially if it has changed hands or has been fitted with aftermarket wheels.
What size rim does a 2020 Nissan Trucks Armada use?
A 2020 Nissan Trucks Armada can use 18-inch, 20-inch, or 22-inch rims, depending on the sub-model and tire size. The three primary combinations are 265/70R18 on an 18-inch rim, 275/60R20 on a 20-inch rim, and 275/50R22 on a 22-inch rim.
Rim diameter is the first measurement to confirm because each Armada tire size is tied to a different wheel size. A replacement tire must match the wheel diameter exactly, and that matters even more on a vehicle that may have had wheel upgrades, accessory packages, or previous owner changes.
Why does the 2020 Nissan Trucks Armada have more than one tire size?
The 2020 Nissan Trucks Armada has more than one tire size because different sub-models use different wheel-and-tire packages. In this lineup, the Armada spans 18-inch, 20-inch, and 22-inch rim diameters, with tire sizes chosen to suit those trim-specific wheel configurations.
That variation means a buyer should not select tires by model name alone. The safer approach is to identify the exact trim, confirm the wheel diameter currently on the vehicle, and then choose the matching size so the replacement maintains the intended fitment relationship between tire, wheel, and body clearance.
Choosing the Right Tire
What should I consider when choosing a 2020 Nissan Trucks Armada tire?
Start with the correct trim-specific size: 265/70R18, 275/60R20, or 275/50R22. On a 2020 Nissan Trucks Armada, size and wheel diameter come first, followed by making sure the replacement remains a radial tire in the same format used for the vehicle's original fitment group.
After the size is confirmed, compare tires based on how the Armada is actually used, whether that is family road use, towing-aware driving, or general full-size SUV service. It also helps to verify that all four wheels match, since mixed wheel packages or changed spare-wheel arrangements can complicate replacement planning.
How do I choose between the available 275/50R22, 275/60R20, and 265/70R18 tires for a 2020 Nissan Trucks Armada?
The choice between 275/50R22, 275/60R20, and 265/70R18 is not a matter of preference alone, because each size belongs to a specific Armada wheel setup. The right tire is the one that matches the wheel diameter and trim configuration already on the vehicle.
Once the size is confirmed, the real comparison is within that size rather than across all three. Looking at tire design, intended service, and the condition of the current wheel setup makes more sense than trying to substitute one Armada size for another without checking wheel compatibility and clearance.
What rim-fitment details should I compare when choosing 2020 Nissan Trucks Armada tires?
Rim diameter is the non-negotiable starting point on the 2020 Nissan Trucks Armada, since the model uses 18-inch, 20-inch, and 22-inch wheel fitments. The replacement tire must match that diameter exactly, and the tire size itself tells you which wheel diameter it is built for.
Beyond diameter, it is smart to confirm that the wheels on the vehicle are the correct set for the trim and have not been changed to aftermarket pieces with a different width or offset. That extra check helps avoid rubbing, stance changes, or other fitment problems that can appear even when the tire size looks close.
Restoration & Appearance
Does correct tire fitment matter for a 2020 Nissan Trucks Armada restoration or preservation project?
Yes. Even though the 2020 Nissan Trucks Armada is a modern vehicle compared with vintage collector cars, correct tire fitment still matters when the goal is preservation, resale presentation, or keeping the SUV visually true to its trim-specific configuration. The right size helps maintain the intended relationship between wheel diameter, sidewall profile, and overall stance.
That is especially important on an Armada because the difference between 18-inch, 20-inch, and 22-inch wheel packages changes the vehicle's appearance noticeably. A clean preservation-minded approach starts with the proper size for the trim, then confirms that the current wheels and any spare-wheel arrangement still match that setup.
How does tire size affect the appearance of a 2020 Nissan Trucks Armada?
Tire size has a visible effect on the 2020 Nissan Trucks Armada because the model uses three different wheel diameters across its sub-model range. A 265/70R18 presents more sidewall, a 275/60R20 strikes a middle ground, and a 275/50R22 gives the vehicle a larger-wheel, lower-profile look.
That means appearance decisions should begin with the trim's proper fitment rather than a guess based only on what looks good in photos. On a full-size SUV like the Armada, staying with the intended size helps preserve proportion and avoids the mismatched look that can come from using a tire built for another wheel package.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2020 Nissan Trucks Armada?
Yes. Modifications can affect tire fitment on a 2020 Nissan Trucks Armada even when the replacement tire matches one of the original size options. Aftermarket wheels, suspension changes, leveling kits, or body alterations can change the clearance relationship around the tire and wheel assembly.
That is why it helps to inspect the vehicle as it sits today rather than relying only on the original trim specification. Checking wheel diameter, wheel width, offset, and clearance at steering lock can prevent surprises, especially on a used Armada that may no longer carry its original wheel-and-tire package.
What should I inspect before driving a 2020 Nissan Trucks Armada on new tires?
Before driving a 2020 Nissan Trucks Armada on new tires, inspect the wheels for damage, confirm the tire size matches the wheel diameter, and make sure the tires are mounted and inflated properly. It is also worth checking for uneven wear patterns on the old tires, since they can point to alignment or suspension concerns.
A full-size SUV places real demand on its tires, so a quick inspection should also include tread condition on any remaining matched tires, visible sidewall damage, valve stems, and lug hardware. Taking a short initial drive and rechecking pressure afterward is a practical way to catch issues early.
What should I check before a longer drive in a 2020 Nissan Trucks Armada?
Before a longer drive, confirm that the 2020 Nissan Trucks Armada is riding on the correct tire size for its wheel package and that all tires are in sound condition. Pressure, tread depth, visible cracking, cuts, bulges, and any sign of slow air loss deserve attention before putting extended highway miles on the vehicle.
It also helps to inspect the spare, especially if the Armada has seen infrequent use or long storage periods. A longer trip is the wrong time to discover mismatched wheel sizes, an aging spare, or a tire that clears normally in town but rubs under load, full steering input, or rough-road suspension movement.
