The 2015 Nissan Trucks Pathfinder sits in the modern crossover era, blending three-row family utility with the road manners buyers expected from a contemporary Nissan SUV. For owners keeping one on the road today, the tire decision is less about vintage construction and more about matching the exact trim's wheel package. This Pathfinder uses two primary radial sizes: 235/65R18 on S, SL, and SV models, and 235/55R20 on the Platinum. That creates a clear difference in rim diameter and profile between trims. Getting the right tire starts with confirming the sub-model and wheel size, then narrowing choices by driving use, appearance, and overall fitment condition.
Which Tire Size Is Right for The 2015 Nissan Trucks Pathfinder
The 2015 Nissan Trucks Pathfinder uses two primary tire sizes, and the correct one depends on the sub-model and wheel diameter. S, SL, and SV models use one radial size on an 18-inch rim, while the Platinum uses another on a 20-inch rim. Before comparing tires, confirm the trim level and the actual wheel size on the vehicle, especially if wheels have ever been changed.
235/55R20 is a metric radial size in which 235 identifies the nominal section width in millimeters, 55 is the aspect ratio, R indicates radial construction, and 20 is the rim diameter in inches. On the 2015 Nissan Trucks Pathfinder, this size applies to the Platinum and reflects that trim's 20-inch wheel package. With a lower profile than the 18-inch fitment, the size changes the tire's visual proportion as well as the wheel-and-tire relationship. Choose this size only after confirming the Pathfinder still has the correct 20-inch wheels and adequate clearance throughout the steering range.
235/65R18 is a metric radial size where 235 is the nominal section width in millimeters, 65 is the aspect ratio, R marks radial construction, and 18 is the rim diameter in inches. This is the primary fitment for the S, SL, and SV versions of the 2015 Nissan Trucks Pathfinder. Its dimensions place it very close in overall diameter to the 20-inch fitment, but it belongs to a different wheel diameter and should not be treated as interchangeable without the proper wheels. It is the right place to start when the vehicle carries the standard 18-inch setup.
Tire fitment on the 2015 Nissan Trucks Pathfinder varies by sub-model, so trim identification matters before anything else. Three sub-models share the same 18-inch radial size, while the Platinum uses a different radial size on a 20-inch wheel.

2015 Nissan Trucks Pathfinder Platinum
The 2015 Nissan Trucks Pathfinder Platinum uses the 235/55R20 radial size, making it the trim that requires the 20-inch wheel fitment. Tire selection starts with confirming those 20-inch wheels are still on the vehicle, then choosing a tire that matches the Pathfinder's intended road use and overall setup.
The 2015 Nissan Trucks Pathfinder S uses the 235/65R18 radial size on an 18-inch wheel. That makes tire selection fairly straightforward as long as the wheel setup remains stock-sized, with the main focus shifting to choosing the right tire within that size.
The 2015 Nissan Trucks Pathfinder SL uses the 235/65R18 radial size, matching the other 18-inch wheel trims. For this sub-model, the main fitment step is confirming the vehicle still carries the correct wheel diameter before comparing tire options in the proper size.
The 2015 Nissan Trucks Pathfinder SV uses the 235/65R18 radial size on an 18-inch rim. That shared fitment keeps selection simple, but it is still worth checking the actual wheels on the vehicle if a previous owner changed the factory-style setup.
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
Pathfinder owners usually need to sort out trim-specific tire size, 18-inch versus 20-inch wheel fitment, and what to inspect before putting the vehicle back into regular road use. These answers focus on the exact 2015 Nissan Trucks Pathfinder and its two primary radial sizes.
Tire Size & Fitment
What tire size fits a 2015 Nissan Trucks Pathfinder?
The 2015 Nissan Trucks Pathfinder uses two tire sizes depending on sub-model. The Platinum uses 235/55R20, while the S, SL, and SV use 235/65R18. Both are radial tire sizes, but they are tied to different wheel diameters and should be matched to the correct trim and wheel setup.
The practical first step is checking the actual wheels on the vehicle before choosing tires. A Pathfinder with 20-inch wheels needs the 235/55R20 fitment, while an 18-inch wheel setup takes 235/65R18. If the vehicle has aftermarket wheels or a prior wheel swap, confirm diameter, width, and clearance before assuming the original trim-based size still applies.
What size rim does a 2015 Nissan Trucks Pathfinder use?
A 2015 Nissan Trucks Pathfinder uses either an 18-inch or 20-inch rim, depending on sub-model. The 235/65R18 tire fits an 18-inch rim on S, SL, and SV models, while the 235/55R20 tire fits a 20-inch rim on the Platinum. The final number in each tire size is the wheel diameter in inches.
Wheel diameter is the key fitment checkpoint because the two Pathfinder sizes do not share the same rim size. Before replacing tires, read the size already mounted, inspect the wheel itself, and confirm the trim if needed. Vehicles that have had wheel upgrades or replacements should always be measured and verified rather than selected by model name alone.
Do all 2015 Nissan Trucks Pathfinder sub-models use the same tire size?
No, not all 2015 Nissan Trucks Pathfinder sub-models use the same tire size. The S, SL, and SV share 235/65R18, while the Platinum uses 235/55R20. The difference is not just sidewall profile; it also reflects a different wheel diameter between those trims.
That means the buyer should identify the exact sub-model or confirm the actual wheel size before comparing tires. Shared fitment across S, SL, and SV simplifies selection for those trims, but the Platinum stands apart with its 20-inch package. If the Pathfinder has been modified, rely on the wheel-and-tire setup on the vehicle rather than trim badge assumptions.
Choosing the Right Tire
What should I consider when choosing a 2015 Nissan Trucks Pathfinder tire?
Start with the correct size for the specific Pathfinder sub-model: 235/65R18 for S, SL, and SV, or 235/55R20 for Platinum. Since both fitments are radial, the main selection points are proper wheel diameter, the vehicle's actual setup, and choosing a tire that suits how the Pathfinder is used on the road.
It helps to verify the existing wheel size, inspect for any aftermarket changes, and compare the tire's dimensions to the available space in the wheelwell. A family-use Pathfinder that sees regular highway miles may call for a different product emphasis than one used more lightly. Correct size comes first, and then the final choice becomes a matter of intended use and condition.
How do I choose between the available 235/65R18 and 235/55R20 tires for a 2015 Nissan Trucks Pathfinder?
The choice between 235/65R18 and 235/55R20 is not a matter of preference alone, because each size belongs to a different Pathfinder trim and wheel diameter. S, SL, and SV models use 235/65R18, while the Platinum uses 235/55R20. The correct tire is the one that matches the wheels currently on the vehicle.
Once the wheel size is confirmed, compare tires within that size rather than trying to move between the two fitments casually. The two sizes have similar overall diameters, but they are built for different rims and give the Pathfinder a different wheel-to-sidewall balance. Any attempt to change sizes should include wheel compatibility and clearance checks first.
How do I choose between the available tires for a 2015 Nissan Trucks Pathfinder?
Choosing a tire for a 2015 Nissan Trucks Pathfinder begins with matching the exact trim and wheel diameter, then narrowing the field within the correct radial size. The Platinum requires 235/55R20, while S, SL, and SV models require 235/65R18. That eliminates most fitment confusion before brand or performance preferences enter the discussion.
After size is settled, focus on how the Pathfinder is actually driven and whether the vehicle remains stock in wheels and suspension. Regular commuting, family travel, seasonal use, and long-distance driving can all influence what characteristics matter most. Tire age and wheel condition also deserve attention, especially if the SUV has sat unused or recently changed owners.
Restoration & Appearance
Does correct tire fitment matter for a 2015 Nissan Trucks Pathfinder restoration?
Yes, correct tire fitment still matters on a 2015 Nissan Trucks Pathfinder, even though it falls well outside the vintage-car era. Using the proper size preserves the intended wheel-to-tire proportion for the specific trim, whether that is 235/65R18 on S, SL, and SV models or 235/55R20 on the Platinum.
Appearance is only part of the equation. The right fitment also helps maintain proper wheel compatibility and avoids creating unnecessary clearance questions through casual size changes. Anyone aiming for an authentic factory-style presentation should confirm the Pathfinder's original trim, current wheel diameter, and any changes made by a prior owner before choosing replacement tires.
How does tire size affect the appearance of a 2015 Nissan Trucks Pathfinder?
Tire size changes the visual balance of a 2015 Nissan Trucks Pathfinder because the two factory-style fitments pair similar overall diameter with different wheel diameters and sidewall proportions. The 235/65R18 used on S, SL, and SV models shows more sidewall, while the Platinum's 235/55R20 gives the wheel a larger visual presence.
That difference means appearance should be considered trim by trim rather than as a single Pathfinder standard. Owners who want to preserve the vehicle's intended look should match the tire size to the correct wheel package already associated with that sub-model. If wheels have been changed, the visual result may differ even when the overall tire diameter remains close.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2015 Nissan Trucks Pathfinder?
Yes, modifications can affect tire fitment on a 2015 Nissan Trucks Pathfinder. Wheel changes, different offsets, suspension alterations, and previous owner upgrades can all change how a 235/65R18 or 235/55R20 tire sits in the wheel opening. Even when the tire size looks familiar, the actual wheel-and-vehicle combination still matters.
A careful check should include wheel diameter, wheel width, steering clearance, and space at the fender and suspension components. That is especially important when moving between 18-inch and 20-inch wheel packages or when the vehicle no longer carries its original trim-specific setup. Physical verification is a safer approach than assuming every Pathfinder still matches its factory wheel package.
What should I inspect before driving a 2015 Nissan Trucks Pathfinder on new tires?
Before driving a 2015 Nissan Trucks Pathfinder on new tires, inspect the wheels for damage, confirm the correct tire size for the trim, and make sure inflation is set appropriately for the vehicle. It is also smart to check for uneven wear patterns that could point to alignment or suspension issues carried over from the old tires.
A short road test should be followed by another look at air pressure and any signs of rubbing at full steering lock. Attention should also go to brake condition, steering response, and vibration, especially on a Pathfinder that has been sitting or recently changed ownership. New tires perform best when the surrounding wheel and suspension hardware are also in sound condition.
How often should tires on a 2015 Nissan Trucks Pathfinder be inspected?
Tires on a 2015 Nissan Trucks Pathfinder should be inspected regularly, not just when tread appears low. Routine checks for air loss, uneven wear, sidewall cuts, cracking, bulges, and embedded debris help catch problems early, whether the SUV runs 235/65R18 or 235/55R20. A quick visual inspection every month is a sensible habit.
More thorough checks make sense before long trips, after pothole impacts, or anytime the Pathfinder develops vibration or a pull in the steering. Vehicles that sit for extended periods deserve extra attention because age, underinflation, and long stationary loads can affect tire condition even when mileage stays low. Consistent inspection supports both safety and tire life.
