The 2018 Nissan Trucks Titan sits in the modern full-size pickup market with a strong focus on towing, everyday truck duty, and trim-specific character that ranges from work-oriented models to more upscale configurations. That matters when it is time to choose tires, because this Titan does not use one universal size across the lineup. Depending on sub-model, it uses 265/70R18, 275/70R18, or 275/60R20 radial tires. The choice is less about vintage-style construction and more about matching the exact trim, wheel diameter, and intended use. A Titan owner should confirm the sub-model first, then compare tire size, wheel setup, and the kind of road or off-road service the truck actually sees.
Which Tire Size Is Right for The 2018 Nissan Trucks Titan
Three tire sizes apply to the 2018 Nissan Trucks Titan, and the right one depends on the exact sub-model and wheel diameter. Two sizes use 18-inch rims, while another uses a 20-inch rim, so the first step is confirming both the trim and the wheels currently on the truck. Once that is established, the decision becomes choosing the right radial tire for the truck's intended use, appearance, and wheel compatibility.
A 275/70R18 is a metric radial size with a 275-millimeter nominal section width, a 70-series aspect ratio, radial construction, and an 18-inch rim diameter. On the 2018 Nissan Trucks Titan, this size is tied to an 18-inch wheel setup and gives the truck a taller sidewall than a 20-inch alternative. Available choices in this size include BFGoodrich with the All Terrain TA KO2 series and a raised white letter sidewall. This size deserves a closer look when the truck is used beyond pavement and the owner wants to preserve the correct wheel diameter and trim-specific fitment.
A 275/60R20 uses the same 275-millimeter nominal width as the 18-inch version, but the 60-series profile pairs with a 20-inch rim. For the 2018 Nissan Trucks Titan, that makes this a trim-dependent modern radial fitment rather than a simple substitute for the 18-inch sizes. Its lower-profile sidewall changes the wheel-and-tire package visually and requires the correct 20-inch wheel to match. This size should be chosen only when it matches the truck's specific sub-model and current wheel setup, especially on Titans that may have had wheels changed over time.
A 265/70R18 is a metric radial size with a 265-millimeter nominal section width, a 70-series profile, and an 18-inch rim diameter. On the 2018 Nissan Trucks Titan, it serves as one of the 18-inch fitments and differs from 275/70R18 mainly in width rather than wheel diameter. That means the buyer still needs to match the exact trim and wheel configuration instead of assuming every 18-inch Titan uses the same tire. This size is a practical starting point for trucks that retain their original-style 18-inch wheel package and need a fitment-first replacement.
Tire fitment varies across the 2018 Nissan Trucks Titan lineup, so identifying the exact sub-model is essential before comparing tire choices. Some trims share a size, while others use a different 18-inch or 20-inch wheel and tire package.

2018 Nissan Trucks Titan PRO-4X
The 2018 Nissan Trucks Titan PRO-4X uses the 275/70R18 radial size. That makes the key decision less about multiple primary sizes and more about selecting an 18-inch radial that suits the truck's intended use and matches the existing wheel setup.
The 2018 Nissan Trucks Titan Platinum Reserve uses the 275/60R20 radial size. Tire selection starts with confirming the 20-inch wheel package, then comparing tires that maintain the correct size and overall fitment for this trim.
The 2018 Nissan Trucks Titan S uses the 265/70R18 radial size. For this sub-model, the focus should be on choosing the right 18-inch replacement tire and confirming that the truck has not been changed to a different wheel package.
The 2018 Nissan Trucks Titan SL uses the 275/60R20 radial size. That points the buyer toward 20-inch radial options and makes wheel-diameter confirmation especially important if the truck has seen aftermarket changes.
The 2018 Nissan Trucks Titan SV can use either 265/70R18 or 275/60R20, depending on the wheel and trim configuration. This is the Titan sub-model where checking the truck itself matters most before choosing a tire, since two primary sizes are used.
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.

Tire Size & Fitment
What tire size fits a 2018 Nissan Trucks Titan?
The 2018 Nissan Trucks Titan uses three different radial tire sizes across the lineup: 265/70R18, 275/70R18, and 275/60R20. The correct size depends on the sub-model. PRO-4X uses 275/70R18, Platinum Reserve and SL use 275/60R20, S uses 265/70R18, and SV can use either 265/70R18 or 275/60R20.
That means there is not one universal Titan tire size for 2018. Before choosing a replacement, confirm the trim and check whether the truck still has its original wheel diameter. This matters most on the SV, since it appears with both 18-inch and 20-inch fitments. A quick look at the current tire sidewall and wheel size can prevent ordering the wrong package.
What size rim does a 2018 Nissan Trucks Titan use?
The 2018 Nissan Trucks Titan uses either an 18-inch or 20-inch rim, depending on sub-model and tire size. The 265/70R18 and 275/70R18 sizes use 18-inch rims, while 275/60R20 uses a 20-inch rim. Those rim diameters are part of the tire size itself, so the last number in each size is a key fitment detail.
Wheel diameter should be confirmed before looking at any other tire specification. A truck set up for 18-inch tires cannot simply take a 20-inch tire without the matching wheel, and the reverse is also true. If the Titan has aftermarket wheels, verify the wheel diameter stamped on the rim and compare it to the tire size currently mounted before making a selection.
Do all 2018 Nissan Trucks Titan sub-models use the same tire size?
No, the 2018 Nissan Trucks Titan lineup uses different tire sizes by sub-model. The S uses 265/70R18, the PRO-4X uses 275/70R18, and the Platinum Reserve and SL use 275/60R20. The SV is the exception because it appears with either 265/70R18 or 275/60R20.
That variation means trim level is a real fitment issue, not just a cosmetic detail. Buyers should identify the exact sub-model first and then confirm the wheel diameter on the truck itself. This is especially important on used Titans, where wheel changes are common enough to create confusion between 18-inch and 20-inch tire packages.
Choosing the Right Tire
What should I consider when choosing a tire for a 2018 Nissan Trucks Titan?
Start with the exact tire size and rim diameter that match the truck's sub-model. On a 2018 Nissan Trucks Titan, that means confirming whether the truck uses 265/70R18, 275/70R18, or 275/60R20. Construction is straightforward because the primary fitments here are radial, so the real choice is matching the correct size to the truck's wheel package and use.
After size is confirmed, compare details that affect how the truck will be used, including load specification, rim-width compatibility, and tread style. A Titan used for highway driving may call for a different approach than one that sees rougher surfaces or mixed use. Wheel changes, suspension changes, or past owner modifications should be checked before settling on any replacement tire.
What sidewall styles are available for 2018 Nissan Trucks Titan tires?
Among the currently covered options for the 2018 Nissan Trucks Titan, the visible sidewall style available in 275/70R18 is RWL, or raised white letter. That appears on the BFGoodrich All Terrain TA KO2. Sidewall treatment affects the truck's overall look, especially on a full-size pickup where the tire has a strong visual presence.
A sidewall choice should still come after the correct size and wheel diameter are confirmed. Appearance matters, but fitment matters first. On a Titan that keeps its original-style wheel setup, sidewall style becomes part of the truck's presentation, while on a modified truck it should be considered alongside wheel width, clearance, and the kind of driving the tire will actually see.
What brands offer tires for the 2018 Nissan Trucks Titan?
BFGoodrich is available for the 2018 Nissan Trucks Titan in the covered 275/70R18 size, with the All Terrain TA KO2 series represented. That gives Titan owners at least one recognizable option in a trim-specific size that is commonly associated with truck use and a more assertive sidewall presentation.
Brand should be one part of the decision, not the whole decision. The more important question is whether the tire matches the Titan's exact size, rim diameter, and intended use. A truck that spends most of its time on the street may be evaluated differently than one used on gravel, trails, or mixed terrain, so compare the full tire specification rather than the name alone.
Restoration & Appearance
Does correct tire fitment matter for a 2018 Nissan Trucks Titan restoration?
Yes, correct tire fitment still matters on a 2018 Nissan Trucks Titan, even though it is a modern truck rather than a vintage restoration project. The right size keeps the truck aligned with its trim-specific wheel package, whether that means 18-inch or 20-inch fitment. Using the wrong size can change the look of the truck and complicate wheel compatibility.
A restoration-minded owner should begin with the exact sub-model and verify whether the truck still carries its original-style wheels. From there, the tire can be chosen to preserve the intended visual balance of the truck. If absolute as-delivered accuracy is the goal, compare the current setup with build records, window sticker information, or marque-specific references before making a final choice.
Which tire should I choose for a period-style 2018 Nissan Trucks Titan?
A period-style choice for a 2018 Nissan Trucks Titan starts with the tire size that belongs on the truck's exact trim and wheel diameter. For a PRO-4X, that means 275/70R18, while other trims use either 265/70R18 or 275/60R20. Keeping the correct size does more for the truck's authentic stance than choosing a tire only by aggressive appearance.
After size is settled, the next decision is visual character. In the covered 275/70R18 selection, a raised white letter sidewall is available, which gives the truck a more traditional off-road look. A clean period-style result usually comes from matching the proper wheel-and-tire package to the trim rather than mixing sizes from different Titan sub-models.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2018 Nissan Trucks Titan?
Yes, modifications can affect tire fitment on a 2018 Nissan Trucks Titan. Aftermarket wheels, altered wheel width, suspension lifts or lowering, and body or fender changes can all influence which tire size works correctly on the truck. That matters even more on a Titan lineup that already uses both 18-inch and 20-inch factory wheel diameters.
A truck that has been changed from its original setup should be checked carefully before a replacement tire is chosen. Look at wheel diameter first, then verify width and clearance around the suspension and steering components. Even when the sidewall shows a familiar Titan size, the actual wheel and chassis setup may no longer match the trim's original tire package.
What should I inspect before driving a 2018 Nissan Trucks Titan on new tires?
Before driving a 2018 Nissan Trucks Titan on new tires, inspect the wheel diameter, confirm the tire size matches the sub-model, and make sure the tires are mounted on suitable rims. It also helps to check inflation pressure, lug torque, and visible clearance around suspension components, inner fenders, and steering travel before putting the truck into regular use.
A short road test is a smart follow-up once the truck is back on the ground. Listen for rubbing, watch for vibration, and recheck pressure after the tires have settled in. On a used Titan, it is also wise to inspect alignment and overall suspension condition, since worn components can affect how a new set of tires behaves on the road.
How often should tires on a 2018 Nissan Trucks Titan be inspected?
Tires on a 2018 Nissan Trucks Titan should be inspected regularly, especially before longer trips, towing, or seasonal changes in use. A visual check should include tread wear, cuts, bulges, cracking, uneven shoulder wear, and any signs of air loss. Trucks often see heavier loads and more varied road conditions than passenger cars, so routine inspection matters.
Monthly pressure checks are a sensible habit, and the tires deserve a closer look any time the truck begins to pull, vibrate, or wear tires unevenly. A Titan that sits for stretches should also be checked for flat spotting or age-related deterioration. Consistent inspection helps catch fitment or maintenance issues early, before they turn into larger ride or safety concerns.
