The 2021 Nissan Trucks Frontier sits in the late second-generation Frontier lineup, a midsize pickup known for straightforward durability, usable four-wheel-drive capability, and trim-specific wheel and tire packages. For owners, tire selection is less about vintage-style construction and more about matching the truck’s exact sub-model and wheel setup. This Frontier uses radial tires, with 265/75R16, 265/70R16, and 265/60R18 fitments depending on configuration. Available choices in the covered sizes focus on BFGoodrich All-Terrain T/A KO2 tires with raised white letter styling. The key is confirming the right trim and rim diameter first, then choosing a tire that suits the truck’s intended road and light-trail use.
Which Tire Size Is Right for The 2021 Nissan Trucks Frontier
The 2021 Nissan Trucks Frontier uses three primary tire sizes, and the correct one depends on the exact sub-model and wheel diameter. Two of the fitments use 16-inch wheels, while another uses an 18-inch wheel, so the first step is confirming both the trim and the truck’s actual rim size before comparing tire options.
In 265/75R16, the 265 identifies nominal section width in millimeters, 75 is the aspect ratio, R indicates radial construction, and 16 is the wheel diameter in inches. On the 2021 Nissan Trucks Frontier, this size is used in a radial format and is tied to a 16-inch wheel setup. The available product in this size is a BFGoodrich All-Terrain T/A KO2 with raised white letter sidewalls, giving it a more aggressive truck appearance. This size is the one to evaluate when the truck is equipped with the taller 16-inch fitment rather than the 18-inch package.
The size 265/70R16 uses the same 265-millimeter nominal section width as the other Frontier fitments here, but with a 70-series profile on a 16-inch rim. It is a radial truck tire size and appears across several 2021 Nissan Trucks Frontier sub-models, making it one of the more common fitments in this lineup. In the available product selection, this size is offered as a BFGoodrich All-Terrain T/A KO2 with raised white letter styling. It is the right size to consider when the truck has the 16-inch wheel package associated with S and certain SV configurations.
Fit(s): SV Crew Cab, SV Midnight Edition, and SV Special Edition
Construction: Radial|Rim: 18 in
A 265/60R18 tire keeps the same nominal 265-millimeter section width but uses a lower 60-series profile and mounts on an 18-inch wheel. For the 2021 Nissan Trucks Frontier, this radial fitment belongs to specific SV-based configurations that use the larger rim diameter. The lower-profile format changes the tire-selection conversation because wheel diameter becomes the first thing to confirm before looking at tread or appearance. This is the size to match when the truck carries the 18-inch setup, rather than substituting from one of the 16-inch Frontier fitments.
Tire fitment for the 2021 Nissan Trucks Frontier varies by sub-model, and some SV versions do not share the same wheel package. Checking the exact trim matters here because the correct tire size also determines whether the truck uses a 16-inch or 18-inch rim.

Owners of a 2021 Nissan Trucks Frontier usually need to confirm the correct tire size by trim, wheel diameter, and intended use. These FAQs cover fitment, radial tire selection, sidewall and brand choices, and the checks that matter before road use.
Tire Size & Fitment
What tire size fits a 2021 Nissan Trucks Frontier?
The 2021 Nissan Trucks Frontier uses three primary tire sizes: 265/75R16, 265/70R16, and 265/60R18. The exact fitment depends on the sub-model. PRO-4X uses 265/75R16, S and SV King Cab use 265/70R16, and SV Midnight Edition plus SV Special Edition use 265/60R18. SV Crew Cab can use either 265/60R18 or 265/70R16.
The practical next step is confirming the truck’s exact trim and actual wheel diameter before selecting a tire. On this Frontier, the difference is not just profile but also 16-inch versus 18-inch rim fitment. If the truck has changed hands or has aftermarket wheels, checking the wheel itself can prevent choosing the wrong size.
What size rim does a 2021 Nissan Trucks Frontier use?
A 2021 Nissan Trucks Frontier uses either a 16-inch or 18-inch rim, depending on sub-model and tire size. The 265/75R16 and 265/70R16 fitments use 16-inch wheels, while the 265/60R18 fitment uses an 18-inch wheel. Rim diameter is one of the most important details to verify before ordering replacement tires.
Wheel diameter needs to match the tire exactly, so a 16-inch Frontier tire cannot be mounted on an 18-inch wheel and vice versa. It is also smart to confirm the truck’s actual wheel setup if it has been modified, because some SV configurations appear with more than one factory tire size depending on the wheel package.
Why does the 2021 Nissan Trucks Frontier have more than one tire size?
The 2021 Nissan Trucks Frontier has more than one tire size because different sub-models use different wheel and tire packages. This lineup includes 16-inch and 18-inch fitments, with size differences tied to trims such as PRO-4X, S, and the various SV configurations. That is why the Frontier does not have one universal tire size across the range.
The buyer decision starts with identifying the exact sub-model and then confirming the wheel diameter currently on the truck. That matters especially on SV Crew Cab models, which can use either 265/70R16 or 265/60R18. Once that is settled, the tire search becomes much simpler because the correct primary size is already defined.
Choosing the Right Tire
What should I consider when choosing a 265/70R16 tire for a 2021 Nissan Trucks Frontier?
Start by confirming that 265/70R16 is the correct fitment for the specific 2021 Nissan Trucks Frontier sub-model and that the truck still has a 16-inch wheel. In the available selection, this size is offered as a radial BFGoodrich All-Terrain T/A KO2 with raised white letter sidewalls and a rim-width range of 7.0 to 8.5 inches.
Beyond size, compare how the tire matches the truck’s use and wheel setup. Rim-width compatibility, load capacity, and overall tire type matter more than choosing by appearance alone. A Frontier used for mixed pavement and truck duty may call for different priorities than one kept mostly for casual driving, even within the same size.
What sidewall styles are available for 2021 Nissan Trucks Frontier tires?
Among the available products for the covered 2021 Nissan Trucks Frontier sizes, the visible sidewall style is RWL, or raised white letter. That sidewall treatment appears on the BFGoodrich All-Terrain T/A KO2 options available in the listed 16-inch sizes. It gives the truck a more traditional off-road and light-truck presentation than a plain blackwall.
Sidewall style affects appearance more than basic fitment, so it should be considered after the correct size and wheel diameter are confirmed. Some owners prefer raised white letters for a more rugged look, while others may want a cleaner presentation by mounting the lettering inward if the tire and wheel setup allow for that choice.
What brands offer tires for the 2021 Nissan Trucks Frontier?
The available products for the covered 2021 Nissan Trucks Frontier fitments are from BFGoodrich. In the listed 16-inch sizes, the brand appears through the All-Terrain T/A KO2 line, which is a radial light-truck tire with raised white letter styling. That keeps brand selection straightforward and shifts the focus toward choosing the correct Frontier size first.
Since the brand choice here is narrow, the more meaningful comparison is between the available tire sizes and their related specifications. A buyer should look at the truck’s wheel diameter, the tire’s rim-width range, and load capacity, then decide whether the selected size matches the Frontier’s trim and how the truck is actually used.
Restoration & Appearance
Which tire should I choose for a period-style 2021 Nissan Trucks Frontier?
A period-style choice for a 2021 Nissan Trucks Frontier starts with keeping the exact size that belongs on the truck’s sub-model and wheel package. Since this Frontier uses modern radial sizes, the appearance decision is less about bias-ply versus radial and more about matching the trim’s 16-inch or 18-inch setup and choosing a tire with the right visual character.
For the covered 16-inch sizes, the BFGoodrich All-Terrain T/A KO2 with raised white letters gives the truck a more assertive factory-era light-truck look. Owners focused on preserving the way the truck presents should avoid changing wheel diameter casually, because moving away from the original-size package can alter both stance and overall appearance.
How does tire construction affect the appearance of a restored 2021 Nissan Trucks Frontier?
On a 2021 Nissan Trucks Frontier, tire construction does not create the classic bias-ply versus radial appearance decision seen on older collector vehicles because the primary fitments here are radial. The visible difference comes more from the tire’s sidewall treatment, tread character, and profile within the correct size than from construction type alone.
That means appearance-minded owners should concentrate on keeping the proper 265/75R16, 265/70R16, or 265/60R18 fitment for the truck’s trim and wheel diameter. A raised white letter all-terrain tire creates a different look than a more understated sidewall, and changing wheel size can shift the truck away from its intended visual balance.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2021 Nissan Trucks Frontier?
Yes, modifications can affect tire fitment on a 2021 Nissan Trucks Frontier. Aftermarket wheels, suspension changes, leveling or lowering kits, and body alterations can all change the amount of space available for the tire. Even when the size matches a known Frontier fitment, a modified truck may have different clearance needs than one on its original setup.
Checking wheel diameter is only the first step. Wheel width, offset, steering clearance, and room at the fender and suspension points should also be reviewed before mounting replacement tires. That is especially important on a Frontier that may have changed from a 16-inch package to an 18-inch package or vice versa at some point in its life.
What should I inspect before driving a 2021 Nissan Trucks Frontier on new tires?
Before driving a 2021 Nissan Trucks Frontier on new tires, inspect inflation pressure, bead seating, valve stems, lug-nut torque, and basic tire-to-vehicle clearance. It is also wise to check that the size on the truck matches the correct fitment for the sub-model and wheel diameter. A quick visual look for rubbing points can prevent early problems.
After a short drive, recheck pressure and look again for any contact at full steering lock or over suspension movement. The Frontier’s trim-specific fitments make this especially useful on trucks with replacement wheels or recent suspension work. Catching a clearance or mounting issue early is much easier than discovering it after longer road use.
How should tires on a 2021 Nissan Trucks Frontier be maintained?
Tires on a 2021 Nissan Trucks Frontier should be maintained with regular pressure checks, tread inspections, and periodic examination of the sidewalls for cuts, bulges, cracking, or uneven wear. Rotation intervals, alignment condition, and consistent air retention all matter, especially on a truck that sees mixed road and utility use rather than steady commuter mileage.
Storage and inactivity also count. A Frontier that sits for long periods should still have its tires inspected for age-related condition changes and maintained at the proper pressure. Keeping the truck on the correct size for its wheel package helps maintenance too, because it avoids problems caused by trying to run a tire that does not match the wheel diameter.
