The 2012 Nissan Trucks Armada belongs to the full-size SUV era when generous passenger space, towing capability, and long-distance comfort were central to the vehicle’s appeal. Buyers still look to this generation for family hauling, road-trip use, and light truck duty, which makes proper tire sizing especially important. This Armada uses radial tire fitments in either 275/60R20 or 265/70R18, depending on the sub-model. That means the key decision is not vintage bias-ply versus radial, but confirming the correct wheel diameter first and then choosing the right tire within the proper modern metric size. For an SUV that may see daily driving, towing, or weekend travel, matching the exact sub-model and wheel setup matters before anything else.
Which Tire Size Is Right for The 2012 Nissan Trucks Armada
Two tire sizes apply to the 2012 Nissan Trucks Armada, and the correct one depends on the sub-model and wheel diameter. Platinum and SL models use a 20-inch fitment with 275/60R20 tires, while the SV uses an 18-inch fitment with 265/70R18 tires. The first thing to confirm is which sub-model you have and whether the vehicle is still wearing its original wheel diameter before selecting a replacement tire.
The 275/60R20 size is a metric radial format that uses a 275-millimeter section width, a 60-series aspect ratio, radial construction, and a 20-inch rim diameter. On the 2012 Nissan Trucks Armada, this size is used on Platinum and SL models, giving those trims a lower-profile look than the 18-inch setup. Because it is already a modern radial size, the main selection factors are matching the correct wheel diameter and choosing a tire that suits how the SUV is driven. This is the right fitment to evaluate when your Armada has factory-style 20-inch wheels or an equivalent 20-inch wheel setup.
The 265/70R18 size is also a metric radial, with a 265-millimeter section width, a 70-series profile, radial construction, and an 18-inch rim diameter. On the 2012 Nissan Trucks Armada, this size belongs to the SV sub-model and pairs with an 18-inch wheel. Its interpretation is straightforward, but the practical point is confirming that the vehicle has the correct 18-inch wheel rather than assuming all Armada trims share the same setup. This is the fitment to use when replacing tires on an SV or on any Armada that is currently running the proper 18-inch wheel package.
Sub-model fitment matters on the 2012 Nissan Trucks Armada because tire size changes with trim. Platinum and SL share one size, while the SV uses another, so identifying the exact sub-model and wheel diameter is the first step before comparing replacement tires.

2012 Nissan Trucks Armada Platinum
The 2012 Nissan Trucks Armada Platinum uses a 275/60R20 radial tire. That makes 20-inch wheel confirmation the key starting point, followed by choosing a replacement tire that matches the intended use of a full-size SUV rather than selecting from the 18-inch fitment used on the SV.
The 2012 Nissan Trucks Armada SL also uses a 275/60R20 radial tire. Tire selection is therefore similar to the Platinum, with the main priority being retention of the correct 20-inch fitment unless the vehicle has been changed from its original wheel setup.
The 2012 Nissan Trucks Armada SV uses a 265/70R18 radial tire. For this sub-model, replacement choice starts with the 18-inch wheel package, and it is worth confirming that no later wheel swap or aftermarket change has moved the vehicle onto a different diameter.
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
These FAQs focus on the exact tire sizes used on the 2012 Nissan Trucks Armada, how they vary by sub-model, and what to check before replacing tires on an SUV that may have seen wheel changes, towing use, or daily road miles.
Tire Size & Fitment
What tire size fits a 2012 Nissan Trucks Armada?
The 2012 Nissan Trucks Armada uses two tire sizes: 275/60R20 and 265/70R18. The correct size depends on the sub-model. Platinum and SL models use 275/60R20 radial tires, while the SV uses 265/70R18 radial tires.
That means tire selection starts with trim identification and wheel diameter, not just the model name on the badge. An Armada that has had wheel changes over the years may no longer match its original setup, so it is smart to confirm the actual wheel diameter on the vehicle before purchasing replacement tires.
What size rim does a 2012 Nissan Trucks Armada use?
A 2012 Nissan Trucks Armada uses either an 18-inch or 20-inch rim, depending on the sub-model. The SV is paired with 265/70R18 tires on an 18-inch rim, while the Platinum and SL use 275/60R20 tires on a 20-inch rim.
Rim diameter is the first fitment detail to verify because an 18-inch tire cannot be mounted on a 20-inch wheel, and the reverse is also true. Checking the actual wheel on the SUV is especially important if the Armada has ever been upgraded, repaired with take-off wheels, or fitted with aftermarket wheels.
Do all 2012 Nissan Trucks Armada sub-models use the same tire size?
No, the 2012 Nissan Trucks Armada does not use one tire size across every sub-model. Platinum and SL models share the 275/60R20 radial size, while the SV uses a different radial size, 265/70R18.
This split matters because the difference is tied to wheel diameter as well as tire size. A buyer who chooses by model year alone can easily end up looking at the wrong fitment, so it helps to confirm the trim level and then compare that against the wheels currently installed on the vehicle.
Choosing the Right Tire
What should I consider when choosing a 275/60R20 tire for a 2012 Nissan Trucks Armada?
Start by confirming that the Armada is a Platinum or SL and that it still has the correct 20-inch wheels. The 275/60R20 size is the proper radial fitment for those sub-models, so the main goal is choosing a tire that matches the SUV’s everyday driving, highway use, and any towing or loaded-use expectations.
It also helps to compare the replacement tire’s intended service character with how the vehicle is actually used. An Armada that spends most of its time on pavement may call for a different emphasis than one used for frequent travel or heavier-duty work, but size and wheel compatibility still come first.
What should I consider when choosing a 265/70R18 tire for a 2012 Nissan Trucks Armada?
The first step is confirming that the vehicle is an SV or another Armada currently running the correct 18-inch wheel setup. The 265/70R18 size is the proper radial fitment for that application, so replacement choice should begin with correct size, proper wheel diameter, and the vehicle’s actual driving demands.
Beyond size, think about how the SUV is used year-round. A lightly used family vehicle, a road-trip SUV, and a vehicle that regularly carries passengers or cargo may lead you to compare available tires differently, but none of those preferences should override the need to stay with the proper 18-inch fitment.
How do I choose between the available 2012 Nissan Trucks Armada tires?
The real choice is not between two interchangeable sizes, but between the correct size for the exact Armada configuration. Platinum and SL use 275/60R20, while SV uses 265/70R18, so the correct trim and wheel diameter narrow the decision immediately.
Once that is settled, compare tires based on how the SUV is used and whether the current wheel setup is original or changed. Looking at the wrong diameter is the most common mistake, especially on older full-size SUVs that may have seen wheel swaps, replacement wheels, or trim-to-trim parts changes over time.
Restoration & Appearance
Does correct tire fitment matter for a 2012 Nissan Trucks Armada restoration or clean original-style rebuild?
Yes, correct tire fitment still matters on a 2012 Nissan Trucks Armada, especially when the goal is to preserve an original-style appearance and stance. The vehicle used two different modern radial sizes, with 275/60R20 tied to Platinum and SL models and 265/70R18 tied to the SV.
Keeping the proper size for the correct sub-model helps the SUV look proportionate and avoids visual mismatches caused by the wrong wheel diameter. If originality matters closely, it is worth confirming the trim level and checking the wheel setup already on the vehicle before choosing replacement tires.
How does tire size affect the appearance of a 2012 Nissan Trucks Armada?
Tire size has a noticeable effect on how a 2012 Nissan Trucks Armada sits and presents visually because the two factory-style fitments pair with different wheel diameters. The 275/60R20 setup gives a 20-inch-wheel look, while the 265/70R18 setup uses an 18-inch wheel with a taller sidewall profile.
That difference can change the overall character of the SUV even when both sizes are correct for their intended sub-models. Anyone trying to maintain a clean, model-appropriate appearance should match the tire size to the trim and wheel package rather than assuming one Armada fitment suits every version.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2012 Nissan Trucks Armada?
Yes, modifications can affect tire fitment on a 2012 Nissan Trucks Armada. Wheel changes, suspension alterations, leveling or lowering changes, and even replacement wheels from another trim can put the SUV on a different diameter or change the available clearance around the tire.
That is why the current wheel and tire setup should be verified before ordering replacements. A vehicle that started life as an SV may no longer have 18-inch wheels, and a Platinum or SL may have been changed as well, so checking wheel diameter and visual clearance is an important first step.
What should I inspect before driving a 2012 Nissan Trucks Armada on new tires?
Before putting a 2012 Nissan Trucks Armada into regular road use on new tires, inspect the wheels for damage, confirm the tire size matches the installed rim diameter, and make sure the tires are inflated properly for the vehicle’s use. It is also smart to check for obvious alignment or suspension issues.
A quick walkaround should also include looking for rubbing points, unusual steering clearance concerns, and any signs that the old tires wore unevenly. On a full-size SUV, those details matter because extra weight, passenger use, towing, or rough roads can magnify problems that a simple tire change will not solve.
How often should tires on a 2012 Nissan Trucks Armada be inspected?
Tires on a 2012 Nissan Trucks Armada should be inspected regularly, not just when they look visibly worn. A good routine includes checking pressure often, looking over the tread and sidewalls during normal washing or fueling, and giving the tires a closer inspection before longer drives or heavier-use trips.
Pay attention to cracking, cuts, bulges, punctures, and uneven tread wear, since each can point to a tire or chassis issue that needs attention. Full-size SUVs can hide problems until they become more serious, so regular inspection helps catch issues early and confirms that the correct 18-inch or 20-inch setup remains in place.
