The 2018 Nissan Trucks Titan XD sits in the space between a light-duty pickup and a heavier work-focused truck, giving it a distinct place in the modern full-size market. Buyers often choose it for its blend of towing presence, crew-cab comfort, and trim-specific personalities that range from straightforward work use to more upscale road manners. Tire fitment on the 2018 Nissan Trucks Titan XD is entirely radial, but the exact size changes by sub-model, with 17-, 18-, and 20-inch wheel setups in use. That makes trim identification the first step, followed by matching the truck's intended use to the right construction details, load capacity, and sidewall presentation.
Which Tire Size Is Right for The 2018 Nissan Trucks Titan XD
The 2018 Nissan Trucks Titan XD uses three primary tire sizes, and the correct one depends on the exact sub-model and wheel diameter. All three fitments are radial, but they are tied to different 17-, 18-, or 20-inch setups, so confirming the truck's trim and actual wheel size should come before comparing tire choices or replacement specifications.
275/65R18 is a modern metric radial size in which 275 is the nominal section width in millimeters, 65 is the aspect ratio, R identifies radial construction, and 18 is the wheel diameter in inches. On the 2018 Nissan Trucks Titan XD, this size is used on an 18-inch setup and keeps the truck in a current light-truck sizing format that most buyers will recognize. Available choices in this size include a BFGoodrich All Terrain TA KO2 with raised white letter sidewall styling. It is the size to evaluate when the truck has the correct 18-inch wheels and an all-terrain look is part of the decision.
265/60R20 is a metric radial size that uses a 265-millimeter nominal section width, a 60-series profile, radial construction, and a 20-inch rim diameter. For the 2018 Nissan Trucks Titan XD, this size belongs to a 20-inch wheel fitment, so wheel diameter verification matters before anything else. The shorter profile relative to the 17- and 18-inch options also means buyers should stay focused on the correct trim and wheel package rather than treating the sizes as interchangeable. This is the fitment to match when the truck is equipped with the proper 20-inch wheel setup from the start.
245/75R17 is a metric radial size where 245 is the nominal section width in millimeters, 75 is the aspect ratio, R indicates radial construction, and 17 is the wheel diameter in inches. On the 2018 Nissan Trucks Titan XD, it is tied to the 17-inch fitment and gives the truck a taller-sidewall tire profile than the 20-inch option. Available products in this size include a BFGoodrich All Terrain TA KO2 with raised white letter sidewall treatment. It is the size to compare when the truck has the correct 17-inch wheels and the goal is to keep the proper fitment while choosing an all-terrain style.
Tire fitment varies across the 2018 Nissan Trucks Titan XD lineup, so the exact sub-model matters before selecting a replacement tire. The key step is confirming whether the truck uses the 17-, 18-, or 20-inch wheel package tied to that trim.

2018 Nissan Trucks Titan XD PRO-4X
The 2018 Nissan Trucks Titan XD PRO-4X uses the 275/65R18 radial tire size. That points the selection process toward the correct 18-inch wheel fitment first, then toward load, rim-width, and tread-style details that suit the truck's actual use.
The 2018 Nissan Trucks Titan XD Platinum Reserve uses the 265/60R20 radial size. Tire selection starts with confirming the 20-inch wheel setup, since that rim diameter separates it clearly from the other Titan XD sub-model fitments.
The 2018 Nissan Trucks Titan XD S uses the 245/75R17 radial tire size. That makes 17-inch wheel confirmation the first fitment check, followed by comparing available tire specifications and sidewall styling within that size.
The 2018 Nissan Trucks Titan XD SL uses the 265/60R20 radial size. The practical takeaway is simple: match the tire to the 20-inch wheel package first, then confirm the truck has not been changed to a different wheel and tire combination.
The 2018 Nissan Trucks Titan XD SV uses the 245/75R17 radial tire size. Buyers should begin by verifying the truck still wears the proper 17-inch wheels, especially if it has seen aftermarket wheel changes or other appearance upgrades.
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 XD?
The 2018 Nissan Trucks Titan XD uses three different radial tire sizes depending on sub-model: 245/75R17, 275/65R18, and 265/60R20. S and SV models use 245/75R17, the PRO-4X uses 275/65R18, and SL and Platinum Reserve models use 265/60R20.
The important takeaway is that tire size is tied directly to trim and wheel diameter, not just to the Titan XD name. Before replacing tires, check the sub-model and confirm the truck still has its current 17-, 18-, or 20-inch wheel setup, especially if it has had aftermarket wheels or previous tire changes.
What size rim does a 2018 Nissan Trucks Titan XD use?
A 2018 Nissan Trucks Titan XD can use 17-inch, 18-inch, or 20-inch rims, depending on the sub-model and tire size installed. The 245/75R17 fitment uses a 17-inch rim, the 275/65R18 fitment uses an 18-inch rim, and the 265/60R20 fitment uses a 20-inch rim.
Rim diameter should be confirmed before comparing tires because these sizes are not meant for the same wheel. Looking at the sidewall size and physically checking the wheel is a smart step on any used truck, since trim badges alone do not rule out earlier wheel swaps or package changes.
Do all 2018 Nissan Trucks Titan XD sub-models use the same tire size?
No, the 2018 Nissan Trucks Titan XD does not use one tire size across the full lineup. S and SV models use 245/75R17, the PRO-4X uses 275/65R18, and SL and Platinum Reserve models use 265/60R20.
That variation means the right replacement tire starts with identifying the exact sub-model and its wheel diameter. It also helps to confirm what is currently on the truck, because a Titan XD that has been modified for appearance or off-road use may no longer be wearing the tire and wheel package associated with its original trim.
Choosing the Right Tire
What should I consider when choosing a tire for a 2018 Nissan Trucks Titan XD?
Start with the correct trim-specific size, because the 2018 Nissan Trucks Titan XD uses 245/75R17, 275/65R18, or 265/60R20 depending on sub-model. After that, compare radial construction details, wheel diameter, rim-width compatibility, load capacity, and whether the tire's tread style matches how the truck is actually driven.
A work-focused truck, a daily-driven truck, and a more appearance-oriented truck may all want something slightly different even within the correct size. It also helps to check whether the truck still wears its intended wheels, since the wrong rim width or a prior wheel change can complicate replacement even when the sidewall size looks close.
What sidewall styles are available for 2018 Nissan Trucks Titan XD tires?
Among the available products for the 2018 Nissan Trucks Titan XD, the visible sidewall style is RWL, or raised white letter. That sidewall treatment appears on the BFGoodrich All Terrain TA KO2 options offered in both 275/65R18 and 245/75R17.
Sidewall styling matters most when the truck's appearance is part of the decision, especially on a pickup that mixes utility with personal-use character. Matching the correct size still comes first, but once that is settled, the sidewall presentation can help shape whether the truck looks more understated, more traditional, or more all-terrain oriented.
What brands offer tires for the 2018 Nissan Trucks Titan XD?
The available products for the 2018 Nissan Trucks Titan XD are from BFGoodrich. In the sizes with product coverage here, the offering is the All Terrain TA KO2 in radial construction for 275/65R18 and 245/75R17 fitments.
That makes the selection process less about comparing many brand names and more about confirming the truck's exact size, wheel fitment, and intended use. Buyers should still compare the tire's rim-width requirements and load specification against the truck's setup, particularly if the Titan XD is used for towing, hauling, or mixed on-road and off-road driving.
Restoration & Appearance
How does tire construction affect the appearance of a 2018 Nissan Trucks Titan XD?
The 2018 Nissan Trucks Titan XD uses radial tires across all of its primary fitments, so the construction itself is already consistent with the truck's original-era design. Appearance differences come more from size, wheel diameter, sidewall profile, tread style, and visible sidewall treatment than from choosing between bias-ply and radial construction.
A 17-inch setup with a taller-profile tire will present the truck differently than a 20-inch fitment with a shorter sidewall, even when both are correct for their trims. For an appearance-minded replacement, match the exact sub-model size first, then choose the sidewall style and tread character that suit the truck's intended look.
Does correct tire fitment matter for a 2018 Nissan Trucks Titan XD restoration or appearance-focused build?
Yes, correct tire fitment matters because the 2018 Nissan Trucks Titan XD uses distinct trim-based sizes tied to different wheel diameters. A truck built around 245/75R17, 275/65R18, or 265/60R20 will look and sit differently, so using the right size helps preserve the proportions intended for that sub-model.
That does not mean every appearance-focused truck must stay completely unchanged, but it does mean changes should be deliberate rather than accidental. Before departing from the original trim's tire size, compare wheel diameter, rim width, and clearance so the finished truck still presents the way you want on the road.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2018 Nissan Trucks Titan XD?
Yes, modifications can affect tire fitment on a 2018 Nissan Trucks Titan XD even when the tire size looks close on paper. Aftermarket wheels, suspension changes, leveling kits, ride-height changes, and body modifications can all alter clearance, rim-width suitability, and the relationship between the tire and the wheel opening.
That matters because this truck already uses different factory wheel diameters across its sub-models. A Titan XD that has been changed from its original setup should be checked for wheel diameter, wheel width, steering clearance, and fender clearance before replacement tires are chosen, especially if it sees towing, hauling, or off-pavement use.
What should I inspect before driving a 2018 Nissan Trucks Titan XD on new tires?
Before regular road use, inspect the new tires for correct size, proper inflation, and even seating on the wheel. It is also wise to confirm that the truck's wheels are the correct diameter for the installed tires and to make sure there is no rubbing at full steering lock or through suspension movement.
A broader walk-around should include checking for cuts, bulges, visible sidewall damage, and any sign of air loss after installation. On a truck like the Titan XD, wheel hardware torque, alignment condition, and the general condition of suspension and steering components are also worth checking before longer drives or heavier use.
How often should tires on a 2018 Nissan Trucks Titan XD be inspected?
Tires on a 2018 Nissan Trucks Titan XD should be inspected regularly rather than only when a problem appears. Frequent checks for inflation, tread wear, cuts, punctures, bulges, and uneven wear are especially important on a full-size truck that may carry heavier loads or spend time on rougher surfaces.
A quick visual check before routine driving is a good habit, and a more careful inspection makes sense before towing, hauling, or taking a longer trip. Trucks that sit for stretches should also be checked for air loss and age-related condition changes, since low-use vehicles can still develop tire issues while parked.
