The 2019 Nissan Trucks Titan sits in the modern full-size pickup market with a broad spread of work, luxury, and off-road personalities, so tire fitment depends heavily on the exact trim. On this truck, the tire conversation starts with three radial sizes: 265/70R18, 275/70R18, and 275/60R20, spread across 18-inch and 20-inch wheel setups. That makes trim identification and wheel confirmation more important than simply matching the model name. For a buyer choosing tires for a Titan, the real decision is balancing the correct metric size with the truck's intended use, wheel package, and, where available, the right product style and specification.
Which Tire Size Is Right for The 2019 Nissan Trucks Titan
Three tire sizes apply to the 2019 Nissan Trucks Titan, and they are tied to specific sub-models and wheel packages rather than one universal fitment. The first step is confirming the exact trim and whether the truck has 18-inch or 20-inch wheels, because both sub-model and rim diameter affect the correct selection. Once that is settled, the decision shifts to choosing the right radial tire within the proper size and intended use.
The 275/70R18 size uses a modern metric format: 275 is the nominal section width in millimeters, 70 is the aspect ratio, R identifies radial construction, and 18 is the wheel diameter in inches. On the 2019 Nissan Trucks Titan, this size supports an 18-inch wheel setup and is used on specific trims rather than across the whole model line. Available product choice in this size includes BFGoodrich's All-Terrain T/A KO2 with raised white letter styling. This size is the one to evaluate when the truck's trim and wheel package call for a taller-sidewall 18-inch radial fitment.
The 275/60R20 code follows the same modern metric radial pattern, with a 275-millimeter nominal width, a 60-series profile, radial construction, and a 20-inch rim diameter. For the 2019 Nissan Trucks Titan, this size belongs to trims equipped with 20-inch wheels, so wheel confirmation matters before comparing tires. Its lower-profile look distinguishes it from the 18-inch options and gives this fitment a different visual and wheel-package character. This is the size to pursue when the truck is built around the factory-style 20-inch setup or currently wears that wheel diameter.
The 265/70R18 designation means a 265-millimeter nominal section width, a 70-series aspect ratio, radial construction, and fitment on an 18-inch wheel. Within the 2019 Nissan Trucks Titan range, this size is associated with certain trims and differs from the wider 275-section alternatives used elsewhere in the lineup. Its dimensions place it in a distinct part of the Titan fitment picture, so it should not be treated as interchangeable with the other primary sizes just because the rim diameter may match. This size is the right starting point when the truck's trim and wheel package call for the narrower 18-inch configuration.
Tire fitment varies across the 2019 Nissan Trucks Titan lineup, so the exact sub-model matters before selecting a size. Some trims share the same fitment, while others use a different 18-inch or 20-inch wheel package that changes the correct tire choice.

2019 Nissan Trucks Titan PRO-4X
The 2019 Nissan Trucks Titan PRO-4X uses the 275/70R18 radial size. That makes the key decision less about which primary size fits and more about choosing the right 18-inch radial tire for the truck's wheel setup and intended use.
The 2019 Nissan Trucks Titan Platinum Reserve uses the 275/60R20 radial fitment. Tire selection starts with confirming that 20-inch wheel package, then comparing tires in that exact metric size rather than mixing it with the 18-inch Titan options.
The 2019 Nissan Trucks Titan S uses the 265/70R18 radial size. For this trim, the focus is staying with that 18-inch metric fitment and checking the actual wheel setup carefully if the truck has been altered from its original configuration.
The 2019 Nissan Trucks Titan SL uses the 275/60R20 radial size. That points the buyer toward 20-inch tire selection first, with attention to matching the truck's wheel diameter before comparing tread design, sidewall treatment, or other product details.
The 2019 Nissan Trucks Titan SV can use either 265/70R18 or 275/60R20, depending on how the truck is equipped. For this trim especially, confirming the actual wheel diameter on the vehicle is the first step before choosing any tire.
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.
Best 2019 Nissan Trucks Titan Tires for Sale
Available product coverage for the 2019 Nissan Trucks Titan is centered here on 275/70R18, with a BFGoodrich All-Terrain T/A KO2 option. That tire combines radial construction, an all-terrain series profile, and raised white letter sidewall styling for buyers comparing appearance and use.
Owners shopping tires for a 2019 Nissan Trucks Titan usually need to sort out trim-specific sizing first, then compare wheel diameter, tire selection, and real-world fitment checks. The questions below focus on those exact Titan decisions.
Tire Size & Fitment
What tire size fits a 2019 Nissan Trucks Titan?
The 2019 Nissan Trucks Titan uses three primary tire sizes: 265/70R18, 275/70R18, and 275/60R20. These are all radial sizes, and they do not apply universally across every Titan trim, so the correct choice depends on the exact sub-model and wheel package on the truck.
A Titan S uses 265/70R18, a PRO-4X uses 275/70R18, and Platinum Reserve and SL use 275/60R20. The SV can use either 265/70R18 or 275/60R20, which makes wheel verification especially important before ordering tires or comparing replacement options.
What size rim does a 2019 Nissan Trucks Titan use?
The 2019 Nissan Trucks Titan uses either an 18-inch or 20-inch rim, depending on the trim and tire size. The 265/70R18 and 275/70R18 sizes use 18-inch wheels, while the 275/60R20 size uses a 20-inch wheel.
Because the Titan lineup uses more than one rim diameter, the safest first check is the wheel itself, not just the model year and nameplate. Looking at the size molded on the current tire sidewall and confirming the exact trim helps prevent mixing an 18-inch tire fitment with a 20-inch wheel setup.
Why does the 2019 Nissan Trucks Titan have more than one tire size?
The 2019 Nissan Trucks Titan has more than one tire size because different trims use different wheel and tire packages. The lineup includes 18-inch and 20-inch wheel applications, and some trims share a size while others use a distinct fitment.
That means tire selection starts with identifying whether the truck is an S, SV, PRO-4X, SL, or Platinum Reserve. On an SV, confirming the actual wheel diameter is especially important, since that trim can be equipped with either an 18-inch or 20-inch fitment.
Choosing the Right Tire
What should I consider when choosing a tire for a 2019 Nissan Trucks Titan?
Start with the exact tire size your 2019 Nissan Trucks Titan uses, since the model range spans 265/70R18, 275/70R18, and 275/60R20. After that, focus on whether the tire matches the truck's wheel diameter, load needs, and the way the truck is actually used on road, off pavement, or in mixed driving.
A trim-specific approach matters more on the Titan than on a truck with one universal fitment. Checking the current wheel setup, avoiding assumptions based on another trim, and comparing sidewall style, tire series, and construction details within the correct size will lead to a more useful choice.
What sidewall styles are available for 2019 Nissan Trucks Titan tires?
For the 2019 Nissan Trucks Titan fitments covered here, the available 275/70R18 product uses an RWL sidewall, which means raised white letter styling. That gives the tire a more pronounced visual treatment than a plain blackwall and can influence the truck's overall appearance as much as the tread pattern itself.
Sidewall style should still come after correct fitment. Once the right size and wheel diameter are confirmed, an appearance choice like raised white letters becomes a way to match the truck's intended personality, especially on a trim that benefits from a more rugged, traditional all-terrain presentation.
What brands offer tires for the 2019 Nissan Trucks Titan?
The product coverage shown here for the 2019 Nissan Trucks Titan includes BFGoodrich in 275/70R18. That option appears in the All-Terrain T/A KO2 series and gives buyers a clear brand and tread-family reference point within one of the Titan's primary fitments.
Brand comparison only becomes meaningful after the tire size is settled, since Titan fitment varies by trim. A PRO-4X owner shopping 275/70R18 can compare that BFGoodrich option on its own merits, while owners of other trims should first confirm whether their truck uses 18-inch or 20-inch tires.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2019 Nissan Trucks Titan?
Yes, modifications can affect tire fitment on a 2019 Nissan Trucks Titan, even when the replacement tire matches one of the correct stock sizes. Aftermarket wheels, suspension changes, altered ride height, or body modifications can change clearance at the fenders, steering components, and suspension travel points.
That matters even more on a Titan lineup with both 18-inch and 20-inch fitments. A truck that has been changed from its original wheel package should have its actual wheel diameter, wheel width, and clearance checked carefully before selecting a tire by trim name alone.
What should I inspect before driving a 2019 Nissan Trucks Titan on new tires?
Before driving a 2019 Nissan Trucks Titan on new tires, inspect tire pressure, wheel lug torque, visible bead seating, and any signs of rubbing at full steering lock. It also helps to confirm that all four tires match the intended size and that the wheel diameter corresponds to the truck's actual fitment.
A short, careful road test is useful after installation. During that drive, pay attention to vibration, pull, unusual noise, or contact under turning and compression, since those clues can reveal an issue with wheel setup, clearance, or tire selection that is easier to correct early.
How often should tires on a 2019 Nissan Trucks Titan be inspected?
Tires on a 2019 Nissan Trucks Titan should be inspected regularly, not just when tread looks worn. A routine check should include tread condition, air pressure, cuts, punctures, bulges, uneven wear, and sidewall damage, especially on a truck that sees varied road surfaces or heavier-duty use.
Inspections become even more important when the truck has multiple possible wheel and tire packages across the model line. Staying alert to uneven wear can also help catch inflation or alignment issues early, which protects both tire life and the fitment you selected for the truck.
