The 2019 Nissan Trucks Pathfinder sits in the modern three-row SUV market, blending everyday family use with the higher ride height and road-trip practicality that made the Pathfinder name familiar to many buyers. Its tire fitment reflects that dual role, with three primary radial sizes used across the lineup: 235/55R20, 235/65R18, and 255/60R18. That makes exact trim identification important before choosing a replacement. Depending on sub-model, the decision may center on 18-inch versus 20-inch fitment, or on selecting the right balance of tire profile and width for the vehicle’s current wheel setup. Careful size matching is the starting point for ride quality, appearance, and proper clearance.
Which Tire Size Is Right for The 2019 Nissan Trucks Pathfinder
Three tire sizes apply to the 2019 Nissan Trucks Pathfinder, and they vary by sub-model and wheel diameter. Some versions use an 18-inch radial tire, while others use a 20-inch radial, so the first step is confirming the exact Pathfinder trim and the wheels currently on the vehicle before comparing replacement options.
235/55R20 is a metric radial size where 235 is the section width in millimeters, 55 is the aspect ratio, R identifies radial construction, and 20 is the rim diameter in inches. On the 2019 Nissan Trucks Pathfinder, this size is tied to 20-inch wheel applications and suits trims that use a lower-profile tire than the 18-inch fitments. Its overall dimensions keep it close in height to the other Pathfinder sizes while changing sidewall profile and wheel presentation. This is the size to evaluate when the vehicle is equipped with factory-style or replacement 20-inch wheels.
235/65R18 is a metric radial size with a 235-millimeter section width, a 65-series profile, radial construction, and an 18-inch rim diameter. On the 2019 Nissan Trucks Pathfinder, it serves as one of the core 18-inch fitments and appears on several sub-models. Compared with the 20-inch option, it uses a taller sidewall on a smaller wheel while remaining very similar in overall diameter. This size is the right place to start when the Pathfinder carries 18-inch wheels and a standard-width tire setup rather than the wider Rock Creek configuration.
Fit(s): SL Rock Creek Edition and SV Rock Creek Edition
Construction: Radial|Rim: 18 in
255/60R18 is a metric radial size in which 255 gives the section width in millimeters, 60 is the aspect ratio, R denotes radial construction, and 18 is the wheel diameter in inches. On the 2019 Nissan Trucks Pathfinder, this size is associated with Rock Creek Edition 18-inch fitment and stands apart from the 235-width alternatives by using a wider tire. Its overall height stays close to the other Pathfinder sizes, but width and wheel compatibility still need to be considered carefully. This is the size to confirm when replacing tires on a Rock Creek Edition or a Pathfinder wearing that wider 18-inch setup.
Tire fitment on the 2019 Nissan Trucks Pathfinder depends on the exact sub-model, and not every trim uses the same wheel diameter or tire width. Checking the trim name matters because standard 18-inch applications, wider Rock Creek Edition fitments, and 20-inch wheel setups are all part of this model range.

2019 Nissan Trucks Pathfinder Platinum
The 2019 Nissan Trucks Pathfinder Platinum uses the 235/55R20 radial size, placing it on the 20-inch fitment used within the lineup. Tire selection here starts with confirming that 20-inch wheel setup and then matching the lower-profile sizing that belongs on this sub-model.
The 2019 Nissan Trucks Pathfinder S uses the 235/65R18 radial size, making it one of the standard 18-inch Pathfinder applications. Replacement choice is generally straightforward as long as the vehicle still carries the correct 18-inch wheels and has not been changed to another trim’s wheel package.
The 2019 Nissan Trucks Pathfinder SL can use either 235/55R20 or 235/65R18, so wheel identification is essential before buying tires. This sub-model requires a close check of the wheel diameter currently on the vehicle, since both 18-inch and 20-inch radial fitments are part of the SL range.
2019 Nissan Trucks Pathfinder SL Rock Creek Edition
The 2019 Nissan Trucks Pathfinder SL Rock Creek Edition uses the 255/60R18 radial size, combining an 18-inch wheel with a wider tire than the standard 235-width setups. Tire selection should focus on preserving that wider 18-inch fitment unless the vehicle’s wheels have been changed from its Rock Creek configuration.
The 2019 Nissan Trucks Pathfinder SV uses the 235/65R18 radial size, matching one of the main 18-inch Pathfinder tire configurations. Choosing tires for this sub-model begins with keeping the correct size and then verifying that the current wheel and suspension setup still matches the stock-style 18-inch application.
2019 Nissan Trucks Pathfinder SV Rock Creek Edition
The 2019 Nissan Trucks Pathfinder SV Rock Creek Edition uses the 255/60R18 radial size, which is the wider 18-inch Pathfinder fitment. That makes it important to confirm both the Rock Creek wheel diameter and the 255-width tire setup before moving to any replacement comparison.
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
Common Pathfinder tire questions usually come down to trim-specific size selection, 18-inch versus 20-inch wheel fitment, and what the numbers in each metric radial size actually mean. Buyers also tend to want clear guidance on maintenance, modifications, and choosing the right replacement setup for current road use.
Tire Size & Fitment
What tire size fits a 2019 Nissan Trucks Pathfinder?
The 2019 Nissan Trucks Pathfinder uses three primary tire sizes depending on sub-model: 235/55R20, 235/65R18, and 255/60R18. All three are radial sizes, and the correct one depends on the specific Pathfinder trim and wheel package rather than on the model name alone.
Choosing correctly starts with confirming the exact sub-model and the wheel diameter currently on the vehicle. An SL may use either 18-inch or 20-inch fitment, while Rock Creek Edition models use the wider 255/60R18 setup, so checking the tire sidewall and wheel before replacement helps avoid an unnecessary mismatch.
What size rim does a 2019 Nissan Trucks Pathfinder use?
The 2019 Nissan Trucks Pathfinder uses either an 18-inch or 20-inch rim, depending on sub-model and tire size. The 235/55R20 fitment uses a 20-inch rim, while both 235/65R18 and 255/60R18 use an 18-inch rim.
Wheel diameter should be confirmed before shopping because the Pathfinder range includes more than one factory-style setup. Looking at the size stamped on the current tire is usually the quickest check, and it is also wise to confirm that the vehicle has not been changed to aftermarket wheels that differ from its original trim-level fitment.
Why does the 2019 Nissan Trucks Pathfinder have more than one tire size?
The 2019 Nissan Trucks Pathfinder has more than one tire size because different sub-models use different wheel and tire packages. Standard 18-inch trims, 20-inch versions, and Rock Creek Edition models with a wider 18-inch tire are all part of the Pathfinder lineup.
That means the model year and name are not enough by themselves when choosing tires. Trim level, wheel diameter, and whether the vehicle is a Rock Creek Edition all affect fitment, so the safest approach is to match the replacement tire to the exact setup currently installed unless the wheel package is being intentionally changed.
Choosing the Right Tire
What should I consider when choosing a 2019 Nissan Trucks Pathfinder tire?
Start with the correct size for the exact Pathfinder sub-model: 235/55R20, 235/65R18, or 255/60R18. From there, compare the wheel diameter, the tire width, and the profile that belongs with that setup so the replacement stays aligned with the vehicle’s intended fitment.
It also helps to think about how the Pathfinder is used. A family SUV that spends most of its time on the highway may call for different priorities than one used for mixed-weather commuting, but any choice should still preserve proper wheel compatibility, clearance, and load suitability for the vehicle’s trim and current configuration.
How do I choose between the available 18-inch tires for a 2019 Nissan Trucks Pathfinder?
The 18-inch Pathfinder fitments are 235/65R18 and 255/60R18, and they are not interchangeable simply because they share the same rim diameter. The first is the standard-width 18-inch size used on several trims, while the second is the wider 18-inch size used on Rock Creek Edition models.
Selection begins with identifying whether the vehicle uses the standard 18-inch setup or the wider Rock Creek package. Width, profile, and wheel compatibility all matter, so the replacement should match the vehicle’s actual wheel and trim arrangement rather than being chosen only because it is also an 18-inch radial tire.
How do I choose between the available Pathfinder tire sizes if I have an SL model?
The 2019 Nissan Trucks Pathfinder SL can use either 235/65R18 or 235/55R20, so the deciding factor is the wheel package on the vehicle. Both are correct Pathfinder sizes, but each belongs to a different rim diameter and sidewall profile.
Checking the current tire size and wheel before ordering is especially important on an SL because the trim spans both fitments. A replacement should follow the 18-inch or 20-inch setup already on the SUV unless the wheels are being changed deliberately and the full fitment, clearance, and load implications have been reviewed first.
Restoration & Appearance
Does correct tire fitment matter for the appearance of a 2019 Nissan Trucks Pathfinder?
Yes, correct tire fitment has a visible effect on a 2019 Nissan Trucks Pathfinder because wheel diameter, tire width, and sidewall profile all shape how the SUV sits and looks. The difference between 235/65R18, 255/60R18, and 235/55R20 is not only technical; it also changes the overall visual balance.
Using the proper size helps preserve the intended relationship between the wheel opening, sidewall height, and wheel design. On a newer vehicle like this Pathfinder, appearance usually means staying true to the trim’s original wheel-and-tire package, especially on SL and Rock Creek Edition models where multiple fitment paths exist within the same model year.
Which tire size best preserves the original look of a 2019 Nissan Trucks Pathfinder?
The tire size that best preserves the original look of a 2019 Nissan Trucks Pathfinder is the one that matches its exact sub-model and wheel package. That means 235/55R20 for Platinum, 235/65R18 for S and SV, 255/60R18 for Rock Creek Edition models, and either 18-inch or 20-inch fitment on an SL depending on its wheels.
Keeping the correct size maintains the Pathfinder’s intended stance and sidewall proportion. Buyers considering a different size for style reasons should compare wheel diameter, tire width, and clearance carefully, since a change that seems minor on paper can alter the visual character of the vehicle as well as its fitment relationship.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2019 Nissan Trucks Pathfinder?
Yes, modifications can affect tire fitment on a 2019 Nissan Trucks Pathfinder even when the replacement tire matches one of the known factory sizes. Aftermarket wheels, changes in wheel width or offset, suspension alterations, and body modifications can all change how a tire sits in the wheel opening.
A Pathfinder with non-stock wheels or a changed ride height should be checked for clearance at full steering lock and through suspension movement before settling on a replacement. That matters most when moving between the standard 235-width 18-inch setup, the wider 255/60R18 Rock Creek fitment, and the 20-inch 235/55R20 package.
What should I inspect before driving a 2019 Nissan Trucks Pathfinder on new tires?
Before driving a 2019 Nissan Trucks Pathfinder on new tires, inspect the wheel diameter, confirm the replacement size matches the trim, and look over the wheels for damage or distortion. Tire pressure should also be set correctly, and the valves, tread area, and sidewalls should be checked for any shipping or installation damage.
A short first drive should be used to listen for rubbing, vibration, or pull, especially if the SUV has aftermarket wheels or recently changed suspension parts. It is also smart to recheck air pressure after the tires have settled in, since correct inflation plays a major role in ride quality, wear, and general road manners.
What should I check before a longer drive in a 2019 Nissan Trucks Pathfinder?
Before a longer drive in a 2019 Nissan Trucks Pathfinder, make sure the tire size matches the vehicle’s trim and wheel diameter, then inspect for proper inflation, visible cuts, punctures, sidewall bulges, and uneven tread wear. A quick look at the spare and its condition is also worthwhile before leaving.
Longer trips put more emphasis on heat, load, and steady-speed stability, so tires that are old, damaged, or losing air deserve attention before the vehicle heads out. It also helps to confirm that recent wheel changes, brake work, or suspension service have not introduced rubbing or clearance issues that only become obvious after more miles.
