The 2019 Nissan Trucks Armada is a full-size SUV built for families, towing, and long-distance highway use, with the size and road presence buyers expect from a body-on-frame platform. That kind of vehicle places extra importance on getting the tire size, wheel diameter, and overall stance right. This Armada uses two primary radial tire sizes, with 275/60R20 and 265/70R18 depending on the sub-model. The decision is less about bias-ply versus radial and more about confirming the exact trim, matching the correct 18-inch or 20-inch wheel setup, and choosing a tire that suits everyday driving, appearance, and load demands.
Which Tire Size Is Right for The 2019 Nissan Trucks Armada
The 2019 Nissan Trucks Armada uses two primary tire sizes, and the correct choice depends on the specific sub-model and wheel diameter. Both fitments are radial, but they are split between 18-inch and 20-inch rims, so the first step is confirming which wheels are on the vehicle before selecting a replacement tire.
275/60R20 is a modern metric radial size in which 275 indicates section width in millimeters, 60 is the aspect ratio, R identifies radial construction, and 20 is the rim diameter in inches. On the 2019 Nissan Trucks Armada, this size belongs to 20-inch wheel applications and suits trims that use the larger factory-style wheel package. Its dimensions create a substantial SUV tire profile while staying within a familiar modern sizing system. This is the size to evaluate when the Armada is equipped with 20-inch wheels and the goal is to maintain the proper fitment category for that setup.
265/70R18 is a metric radial size where 265 is the section width in millimeters, 70 is the aspect ratio, R denotes radial construction, and 18 is the wheel diameter in inches. On the 2019 Nissan Trucks Armada, this size is tied to 18-inch wheel applications rather than the larger 20-inch setup. It remains a full-size SUV tire format with dimensions close to the larger-wheel alternative, but it is not the same fitment. This is the size to use when the Armada has the correct 18-inch wheels and matching trim configuration.
Tire fitment on the 2019 Nissan Trucks Armada varies by sub-model, so identifying the exact trim matters before choosing a tire. The main distinction is wheel diameter, with some trims using 20-inch wheels and the SV using an 18-inch setup.

2019 Nissan Trucks Armada Platinum
The 2019 Nissan Trucks Armada Platinum uses the 275/60R20 radial tire size. Tire selection for this trim starts with confirming the 20-inch wheel setup, then choosing a replacement tire that maintains the intended fitment and overall SUV profile.
The 2019 Nissan Trucks Armada Platinum Reserve uses the 275/60R20 radial tire size. For this sub-model, the key step is matching the correct 20-inch wheel application rather than assuming interchangeability with Armada trims that use 18-inch rims.
The 2019 Nissan Trucks Armada SL uses the 275/60R20 radial tire size. That keeps tire choice centered on the 20-inch wheel package, so replacement planning should focus on preserving the proper wheel-and-tire combination for the trim.
The 2019 Nissan Trucks Armada SV uses the 265/70R18 radial tire size. This trim requires the 18-inch fitment, which makes wheel confirmation especially important before replacing tires or comparing the SV to Armada models equipped with 20-inch wheels.
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)

Frequently Asked Questions
Common questions for the 2019 Nissan Trucks Armada usually center on the correct tire size by trim, the difference between the 18-inch and 20-inch wheel setups, and what to inspect before putting a full-size SUV back into regular road use.
Tire Size & Fitment
What tire size fits a 2019 Nissan Trucks Armada?
The 2019 Nissan Trucks Armada uses either 275/60R20 or 265/70R18, depending on the sub-model. Platinum, Platinum Reserve, and SL models use 275/60R20, while the SV uses 265/70R18. Both are radial tire sizes, but they are matched to different wheel diameters.
The practical first step is confirming the exact trim and checking whether the vehicle has 18-inch or 20-inch wheels. That matters more than the close overall dimensions of the two sizes, because the correct replacement must match the wheel diameter actually on the Armada and the setup currently on the vehicle.
What size rim does a 2019 Nissan Trucks Armada use?
A 2019 Nissan Trucks Armada uses either an 18-inch rim or a 20-inch rim, depending on the sub-model. The 265/70R18 fitment uses an 18-inch wheel, while the 275/60R20 fitment uses a 20-inch wheel. Both are factory-style radial applications for this model year.
Wheel diameter should be verified before buying tires, especially if the SUV was purchased used or has had wheel changes over time. Looking only at the trim name is not always enough once a vehicle has been modified, so checking the actual wheel and the existing tire sidewall helps prevent an incorrect size choice.
Do all 2019 Nissan Trucks Armada sub-models use the same tire size?
No, the 2019 Nissan Trucks Armada does not use one tire size across every sub-model. Platinum, Platinum Reserve, and SL models use 275/60R20, while the SV uses 265/70R18. The difference is tied to the wheel package rather than a simple naming variation.
That means tire selection starts with sub-model identification and wheel confirmation, not just the model name Armada. An owner comparing replacement options should also check whether the vehicle still has its original wheels, because an SV fitted with 20-inch wheels or another trim fitted with 18-inch wheels would change the tire choice.
Choosing the Right Tire
What should I consider when choosing a tire for a 2019 Nissan Trucks Armada?
Start with the correct size for the exact Armada sub-model: 275/60R20 for Platinum, Platinum Reserve, and SL, or 265/70R18 for SV. Both are radial sizes, so the main decision is not construction type but matching the proper wheel diameter and maintaining the intended fitment.
After confirming size, compare the tire's overall role on the vehicle. A full-size SUV like the Armada benefits from a tire suited to daily driving, passenger comfort, and the vehicle's weight and use. Wheel width, load capability, clearance, and whether the SUV has aftermarket wheels are all worth checking before final selection.
How do I choose between the available 2019 Nissan Trucks Armada tire sizes?
The two sizes are not interchangeable choices for the same wheel. A 2019 Nissan Trucks Armada with 20-inch wheels uses 275/60R20, while one with 18-inch wheels uses 265/70R18. The correct size is determined by the wheel diameter and the sub-model or actual wheel setup on the vehicle.
A useful approach is to verify the wheel size on the vehicle first, then compare replacement tires only within that correct size category. Looking at overall appearance alone can be misleading, because two sizes may seem close in profile while still requiring different wheels and potentially different fitment checks.
What rim-width specifications should I compare when choosing 2019 Nissan Trucks Armada tires?
Rim width matters because a tire must be matched to an appropriate wheel, not just the correct rim diameter. On a 2019 Nissan Trucks Armada, the starting point is choosing the proper size for the actual wheel diameter, then confirming the wheel width is suitable for that tire's intended application.
This becomes especially important on SUVs that may have been fitted with aftermarket wheels. A tire can share the correct 18-inch or 20-inch diameter and still be a poor match if the wheel width is outside the tire's compatible range. Checking both dimensions helps preserve handling, sidewall shape, and clearance.
Restoration & Appearance
Does correct tire fitment matter for a 2019 Nissan Trucks Armada restoration?
Yes, correct tire fitment still matters on a 2019 Nissan Trucks Armada even when the goal is a clean, original-style appearance rather than a vintage restoration. The right size preserves the intended relationship between the tire, wheel, and body, and keeps the SUV from looking under-tired or mismatched.
Appearance should still follow fitment, not replace it. Confirm the Armada's actual wheel diameter first, then choose the proper 275/60R20 or 265/70R18 size for that setup. If originality is especially important, compare the current wheel-and-tire package to vehicle-specific references so the finished look stays consistent with the trim.
How does tire size affect the appearance of a 2019 Nissan Trucks Armada?
Tire size has a visible effect on how a 2019 Nissan Trucks Armada sits and fills the wheel openings. The 275/60R20 and 265/70R18 fitments are both substantial SUV sizes, but each is proportioned around a different wheel diameter, which changes the overall visual balance of tire sidewall and wheel face.
That matters when replacing worn tires on a vehicle you want to keep looking properly sorted. Matching the correct size to the wheel package helps preserve the intended stance, while using the wrong diameter immediately creates a fitment problem. Any custom wheel change should be checked carefully before selecting replacement tires.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2019 Nissan Trucks Armada?
Yes, modifications can affect tire fitment on a 2019 Nissan Trucks Armada. Aftermarket wheels, suspension changes, leveling kits, lowering, or body alterations can all change the space available around the tire and may also alter which size makes sense for the vehicle's current setup.
That is why the trim-based factory size should be treated as the starting point, not the only thing to check. Measure the actual wheel diameter and width, then inspect clearance at full steering lock and through suspension movement. A modified Armada should always be evaluated as it sits before replacement tires are chosen.
What should I inspect before driving a 2019 Nissan Trucks Armada on new tires?
Before driving a 2019 Nissan Trucks Armada on new tires, inspect the wheels for damage, confirm the tire size matches the wheel diameter, and check that inflation is set appropriately for the tire and vehicle use. It is also smart to look over the suspension, steering components, and alignment condition.
A full-size SUV places real demands on its tires, so early checks matter. Watch for any rubbing, unusual vibration, air loss, or irregular wear once the new tires are installed. Taking a short initial drive and rechecking pressure and wheel fasteners helps confirm that the Armada is ready for normal road use.
How often should tires on a 2019 Nissan Trucks Armada be inspected?
Tires on a 2019 Nissan Trucks Armada should be inspected regularly, not just when tread appears worn. Monthly pressure checks are a good habit, and visual inspections should look for cuts, bulges, punctures, uneven wear, and sidewall damage. A full-size SUV can mask early tire issues until they become more serious.
Long trips, towing duty, rough roads, and seasonal temperature changes all make more frequent inspections worthwhile. It also helps to check tread wear across the full width of the tire, since alignment or suspension issues can show up there first. Catching problems early supports ride quality, stability, and tire life.
