The 2020 Nissan Trucks Pathfinder sits in the modern three-row SUV category, blending family-duty practicality with the tougher styling and light adventure image that helped keep the Pathfinder name relevant well beyond its earlier truck-based years. Tire selection on this model starts with identifying the exact trim, because the Pathfinder uses three different primary radial sizes: 235/55R20, 235/65R18, and 255/60R18. That means the real choice is not only size, but also confirming whether the vehicle rides on 18-inch or 20-inch wheels. For owners replacing worn tires or correcting a changed wheel setup, getting the trim-level fitment right comes before comparing tread style, load capability, and overall road-use priorities.
Which Tire Size Is Right for The 2020 Nissan Trucks Pathfinder
The 2020 Nissan Trucks Pathfinder uses three primary tire sizes, and the correct one depends on the exact sub-model and wheel diameter. Two sizes fit 18-inch wheels and one fits a 20-inch wheel, so the first step is confirming the trim and checking the actual wheels on the vehicle before comparing replacement tire choices.
A 235/55R20 tire uses a 235-millimeter section width, a 55-series aspect ratio, radial construction, and a 20-inch rim. On the 2020 Nissan Trucks Pathfinder, this size represents the larger-wheel fitment and should be matched to a Pathfinder that is already equipped with 20-inch wheels. Its proportions differ from the 18-inch Pathfinder sizes even though the overall diameter stays in a similar range. This is the size to evaluate when keeping the vehicle on its present 20-inch wheel setup rather than converting to a different wheel diameter.
A 235/65R18 tire pairs a 235-millimeter section width with a 65-series profile, radial construction, and an 18-inch rim. On the 2020 Nissan Trucks Pathfinder, this is the standard 18-inch fitment used across several sub-models, making it the most widely shared size in the lineup. It combines the same basic width as the 20-inch fitment with a taller sidewall to suit a smaller wheel diameter. This size deserves close attention when replacing tires on S, SL, or SV models, especially if the vehicle may have had its wheels changed since new.
Fit(s): SL Rock Creek Edition and SV Rock Creek Edition
Construction: Radial|Rim: 18 in
A 255/60R18 tire uses a wider 255-millimeter section width, a 60-series profile, radial construction, and an 18-inch rim. For the 2020 Nissan Trucks Pathfinder, this size is tied to specific Rock Creek Edition sub-models rather than the full Pathfinder range. Compared with the other 18-inch option, it adds width while keeping a similar overall diameter, which can affect appearance and wheel-setup decisions. This is the size to confirm when the Pathfinder carries Rock Creek Edition trim and still retains its original 18-inch wheel configuration.
Sub-model fitment matters on the 2020 Nissan Trucks Pathfinder because tire size changes with trim and wheel package. Before choosing a replacement tire, confirm the exact Pathfinder sub-model and verify whether the vehicle is on 18-inch or 20-inch wheels.

2020 Nissan Trucks Pathfinder Platinum
The 2020 Nissan Trucks Pathfinder Platinum uses the 235/55R20 radial size, making it the Pathfinder trim in this group with the 20-inch wheel fitment. Tire selection here starts with staying within that wheel diameter and confirming the vehicle has not been changed to a different wheel package.
The 2020 Nissan Trucks Pathfinder S uses the 235/65R18 radial size, which is shared with several other Pathfinder trims. That makes replacement straightforward as long as the vehicle still carries its 18-inch wheels and has not been modified with a different tire and wheel combination.
The 2020 Nissan Trucks Pathfinder SL uses the 235/65R18 radial size on an 18-inch wheel. For replacement, the main task is confirming the Pathfinder remains on its original wheel diameter so the new tire matches the intended fitment rather than a later wheel swap.
2020 Nissan Trucks Pathfinder SL Rock Creek Edition
The 2020 Nissan Trucks Pathfinder SL Rock Creek Edition uses the wider 255/60R18 radial fitment. That makes it important to distinguish this sub-model from a standard SL before selecting tires, since the correct replacement decision centers on preserving the wider 18-inch setup.
The 2020 Nissan Trucks Pathfinder SV uses the 235/65R18 radial size, the same core fitment found on other non-Rock Creek 18-inch Pathfinder trims. Tire selection is mainly about confirming wheel diameter and choosing a tire suited to how the vehicle is actually driven.
2020 Nissan Trucks Pathfinder SV Rock Creek Edition
The 2020 Nissan Trucks Pathfinder SV Rock Creek Edition uses the 255/60R18 radial size rather than the narrower 235/65R18 found on the standard SV. That distinction matters when replacing tires, because the right choice depends on matching the Rock Creek wheel and tire setup already on the vehicle.
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 differences, 18-inch versus 20-inch wheel fitment, and how to choose the right radial tire once the exact sub-model has been confirmed.
Tire Size & Fitment
What tire size fits a 2020 Nissan Trucks Pathfinder?
The 2020 Nissan Trucks Pathfinder uses three tire sizes depending on sub-model: 235/55R20, 235/65R18, and 255/60R18. Platinum models use 235/55R20, S, SL, and SV models use 235/65R18, and the SL Rock Creek Edition and SV Rock Creek Edition use 255/60R18.
The practical takeaway is that trim identification comes first, followed by checking the actual wheel diameter on the vehicle. A Pathfinder that has had wheels swapped, aftermarket rims installed, or a previous nonstandard tire package fitted should be measured and inspected before a replacement tire is chosen.
What size rim does a 2020 Nissan Trucks Pathfinder use?
A 2020 Nissan Trucks Pathfinder uses either an 18-inch or 20-inch rim, depending on sub-model. The 235/65R18 and 255/60R18 sizes both fit 18-inch wheels, while 235/55R20 fits a 20-inch wheel.
Wheel diameter is the first fitment check because a tire must match the rim it is mounted on. Looking only at overall tire height is not enough. Confirm the wheel size stamped on the rim or verify the current tire size on the vehicle before selecting a replacement.
Do all 2020 Nissan Trucks Pathfinder sub-models use the same tire size?
No, 2020 Nissan Trucks Pathfinder sub-models do not all use the same tire size. The Platinum uses 235/55R20, the S, SL, and SV use 235/65R18, and the Rock Creek Edition versions of the SL and SV use 255/60R18.
That difference matters because two Pathfinder trims may look similar but still require different replacement tires. Checking the trim badge helps, but it is still smart to confirm the existing tire size and wheel diameter in case the vehicle has been altered since it left its original configuration.
Choosing the Right Tire
What should I consider when choosing a Pathfinder tire for a 2020 Nissan Trucks Pathfinder?
Start with the exact Pathfinder trim and its correct size: 235/55R20, 235/65R18, or 255/60R18. From there, compare tire type, load capability, tread design, and how the Pathfinder is actually used, whether that means daily driving, highway travel, or occasional rougher-road use.
The best comparison process is to match the tire to the wheel diameter already on the vehicle and then look at the rest of the setup. A Pathfinder with changed wheels, suspension alterations, or previous replacement tires should be checked carefully so the new tire suits both the trim and the current configuration.
How do I choose between the available 18-inch Pathfinder tire sizes for a 2020 Nissan Trucks Pathfinder?
The two 18-inch Pathfinder sizes are 235/65R18 and 255/60R18, and they are tied to different sub-models. Standard S, SL, and SV trims use 235/65R18, while SL Rock Creek Edition and SV Rock Creek Edition use the wider 255/60R18.
Choosing between them is not a matter of preference alone, because each size belongs to a specific Pathfinder setup. Check the trim, read the current sidewall, and confirm the wheels on the vehicle. That keeps the replacement decision tied to the actual fitment instead of assuming all 18-inch Pathfinders use the same tire.
Should I match the existing tire size on my 2020 Nissan Trucks Pathfinder before buying replacements?
Yes, matching the existing tire size is an important starting point on a 2020 Nissan Trucks Pathfinder, but it should be combined with trim and wheel verification. Pathfinder fitment varies by sub-model, and the same model year uses both 18-inch and 20-inch wheel packages.
A quick sidewall check can prevent ordering the wrong size, especially on used vehicles. It is still worth confirming that the current tires reflect the intended Pathfinder setup rather than an earlier owner’s wheel or tire change. That extra step helps avoid clearance, mounting, and handling mismatches.
Restoration & Appearance
Does correct tire fitment matter for a 2020 Nissan Trucks Pathfinder restoration or clean original-style presentation?
Yes, correct tire fitment matters even on a modern Pathfinder when the goal is a clean, original-style appearance. The 2020 Nissan Trucks Pathfinder uses distinct sizes by trim, so keeping the right 18-inch or 20-inch fitment preserves the stance and wheel-to-tire relationship intended for that version.
Appearance can change noticeably when a Pathfinder wears the wrong profile or width, especially if a Rock Creek Edition is fitted with the narrower standard 18-inch size or a Platinum loses its 20-inch setup. Checking the trim and existing wheels first keeps cosmetic decisions grounded in the correct fitment.
Which tire should I choose for a period-style or trim-correct 2020 Nissan Trucks Pathfinder?
For a trim-correct 2020 Nissan Trucks Pathfinder, the right starting point is the size assigned to that specific sub-model. Platinum models belong with 235/55R20, S, SL, and SV trims use 235/65R18, and Rock Creek Edition versions use 255/60R18.
Once the size is correct, the appearance choice becomes much easier because the tire will suit the wheel package and visual proportions of that Pathfinder trim. A vehicle intended to stay close to its original presentation should also avoid casual size substitutions unless the complete wheel and clearance setup is verified.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2020 Nissan Trucks Pathfinder?
Yes, modifications can affect tire fitment on a 2020 Nissan Trucks Pathfinder. Aftermarket wheels, altered offsets, suspension changes, lifts, lowering, or body modifications can change the space available for the original 235/55R20, 235/65R18, or 255/60R18 sizes.
A Pathfinder with nonstock wheels should be checked for rim diameter, width, and clearance before replacement tires are chosen. Steering travel and fender space deserve attention as well. Even when the sidewall size appears familiar, the surrounding wheel and suspension setup may no longer match factory-style fitment assumptions.
What should I inspect before driving a 2020 Nissan Trucks Pathfinder on new tires?
Before road use, inspect tire pressure, wheel-nut torque, valve stems, tread seating, and general tire condition. A 2020 Nissan Trucks Pathfinder should also be checked for even clearance at the struts, fenders, and inner wheelhouse so the chosen size works cleanly through normal driving and full steering movement.
It also helps to look at alignment and suspension condition, especially if the old tires showed uneven wear. New tires cannot correct worn components by themselves. A short initial drive followed by a recheck for pressure stability and any signs of rubbing is a sensible way to confirm everything is working properly.
What should I check before a longer drive in a 2020 Nissan Trucks Pathfinder?
Before a longer trip, confirm that the 2020 Nissan Trucks Pathfinder is on the correct tire size for its trim and that all four tires are in sound condition. Pressure, tread depth, cuts, bulges, irregular wear, and any history of slow air loss deserve attention before highway use.
Longer drives put more heat and load into the tire package, so it is worth checking the spare and making sure the wheels show no visible damage. A Pathfinder that has recently had tire replacement, wheel changes, or suspension work should also be test-driven locally before heading out for extended road use.
