The 2020 Infiniti Trucks QX60 sits in the modern luxury crossover space, blending family-sized practicality with a more upscale, road-oriented character than many traditional truck-based utility vehicles. For owners, tire choice is less about vintage construction and more about matching the vehicle’s exact wheel package. This QX60 uses two primary radial sizes, 235/65R18 and 235/55R20, depending on sub-model and wheel setup. That makes the main decision one of correct size selection first, then comparing tire style, intended road use, and overall presentation within that fitment. Before choosing a replacement, confirm the actual wheel diameter on the vehicle, especially if it has been changed from stock.
Which Tire Size Is Right for The 2020 Infiniti Trucks QX60
Two tire sizes apply to the 2020 Infiniti Trucks QX60, and the first step is confirming which wheel package the vehicle actually has. Both sizes are radial fitments, but they use different rim diameters, so the right choice depends on the exact sub-model and the wheels currently on the vehicle rather than simply choosing by model name alone.
In 235/55R20, the 235 identifies the tire’s nominal section width in millimeters, 55 is the aspect ratio, R indicates radial construction, and 20 is the rim diameter in inches. This is a modern metric radial fitment used on certain 2020 Infiniti Trucks QX60 configurations with 20-inch wheels. Its lower-profile format gives this size a distinct fitment role compared with the 18-inch option. Choose this size only after confirming that the vehicle is equipped with 20-inch wheels, since tire size and wheel diameter must match exactly.
In 235/65R18, the tire is 235 millimeters wide, the 65 aspect ratio indicates a taller sidewall profile than the 20-inch option, R marks it as a radial, and 18 is the wheel diameter in inches. This size serves 2020 Infiniti Trucks QX60 configurations equipped with 18-inch wheels. It is not simply an alternate version of the 20-inch tire, because the rim diameter is different. Select this fitment by verifying the actual wheel on the vehicle and then comparing tire choices within the proper 18-inch size.
Sub-model fitment matters on the 2020 Infiniti Trucks QX60 because some trims can use either 18-inch or 20-inch tire packages, while another is tied to one size. Identifying the exact sub-model and confirming the wheel diameter on the vehicle will keep the tire search focused on the right fitment.

2020 Infiniti Trucks QX60 Luxe
The 2020 Infiniti Trucks QX60 Luxe can use either of the two radial tire sizes offered for this model range, depending on the wheel package installed. That makes wheel confirmation especially important before choosing replacement tires, since 18-inch and 20-inch fitments are not interchangeable.
The 2020 Infiniti Trucks QX60 Luxe Edition 30 uses the 235/55R20 radial fitment. For tire selection, the focus shifts from determining size to comparing the available 20-inch replacements that suit the vehicle’s use, ride expectations, and overall appearance.
The 2020 Infiniti Trucks QX60 Pure can be found with either the 18-inch or 20-inch radial tire fitment. Tire selection starts with confirming the actual wheels on the vehicle, especially if it has changed hands or received replacement wheels during its service life.
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 tire questions for the 2020 Infiniti Trucks QX60 usually center on choosing between 235/65R18 and 235/55R20, matching the tire to the correct wheel package, and checking fitment, condition, and maintenance before regular road use.
Tire Size & Fitment
What tire size fits a 2020 Infiniti Trucks QX60?
The 2020 Infiniti Trucks QX60 uses either 235/55R20 or 235/65R18, and both are radial sizes. The correct fitment depends on the sub-model and wheel package, not just the model name by itself. Luxe and Pure configurations can use either size, while Luxe Edition 30 uses 235/55R20.
The practical step is to confirm the wheel diameter currently on the vehicle before choosing tires. A QX60 with 18-inch wheels requires 235/65R18, and a QX60 with 20-inch wheels requires 235/55R20. Checking the tire sidewall and the wheel itself is especially helpful if the vehicle has had wheel changes or replacement packages installed.
What size rim does a 2020 Infiniti Trucks QX60 use?
A 2020 Infiniti Trucks QX60 uses either an 18-inch or 20-inch rim, depending on the tire size fitted to the vehicle. The 235/65R18 tire mounts on an 18-inch rim, while the 235/55R20 tire mounts on a 20-inch rim. Both fitments use radial construction.
Rim diameter is the first fitment detail to verify because the tire and wheel must match exactly. Even though the two tire sizes are close in overall diameter, they are built for different wheel diameters and cannot be mixed. Once the rim size is confirmed, the next steps are checking the exact tire size, wheel width, and overall clearance on the vehicle.
Do all 2020 Infiniti Trucks QX60 sub-models use the same tire size?
Not every 2020 Infiniti Trucks QX60 sub-model uses the same tire size. The Luxe and Pure trims can use either 235/65R18 or 235/55R20, while the Luxe Edition 30 uses 235/55R20. That means tire fitment varies within the model range rather than staying the same across every covered version.
That variation makes trim identification useful, but wheel confirmation is even more important. A QX60 may have been equipped with different wheels at purchase or changed later in service, so the actual tire size on the vehicle should always be checked before replacement. Matching by visible wheel diameter and sidewall size marking helps prevent ordering the wrong fitment.
Choosing the Right Tire
What should I consider when choosing a tire for a 2020 Infiniti Trucks QX60?
Start with the correct size for the vehicle’s wheel package: 235/65R18 for 18-inch wheels or 235/55R20 for 20-inch wheels. Both are radial fitments, so the core decision is not bias-ply versus radial, but selecting the proper size first and then comparing tire characteristics that suit how the QX60 is actually driven.
After size is confirmed, compare factors such as ride preference, season of use, wheel compatibility, and the condition of the current suspension and alignment. A family-oriented luxury crossover benefits from a tire that matches its intended road use and preserves proper clearance. Vehicles with aftermarket wheels should also have wheel width and fitment checked before a final choice is made.
How do I choose between the available 2020 Infiniti Trucks QX60 tire sizes?
Choosing between 235/65R18 and 235/55R20 is not a styling decision alone; it depends on which wheels are on the 2020 Infiniti Trucks QX60. The 18-inch and 20-inch sizes are tied to different rim diameters, so the right tire is determined by the wheel package already installed on the vehicle.
Once that is settled, compare tires only within the correct size range. Looking at the wrong size can lead to avoidable fitment problems and wasted time. Checking the current sidewall marking, measuring the wheel diameter if needed, and confirming whether the QX60 still has its original wheel setup are the most useful steps before narrowing down replacement options.
Why does the 2020 Infiniti Trucks QX60 have more than one tire size?
The 2020 Infiniti Trucks QX60 has more than one tire size because the model range was offered with different wheel packages. One setup uses 235/65R18 on an 18-inch rim, and another uses 235/55R20 on a 20-inch rim. Both are correct within the right vehicle configuration.
That means the model name alone is not enough for tire selection. A Luxe or Pure may be on either fitment, so the actual wheel and tire currently on the vehicle should be confirmed first. Once the wheel package is known, shopping becomes much simpler because every remaining decision can stay focused on the correct diameter and size.
Restoration & Appearance
Does correct tire fitment matter for a 2020 Infiniti Trucks QX60 restoration or refurbishment?
Correct tire fitment still matters on a 2020 Infiniti Trucks QX60, even though it is a modern vehicle rather than a traditional restoration-era classic. Using the proper 235/65R18 or 235/55R20 size keeps the vehicle visually balanced with its intended wheel package and avoids the mismatched look that can come from choosing by appearance alone.
For a careful refurbishment, start by confirming whether the QX60 retains its original wheel diameter or has been changed. Tire choice should support the vehicle’s intended presentation without creating clearance or compatibility issues. If preserving a specific delivered appearance matters, original sales literature, window-sticker records, or marque-specific references can help verify the proper wheel-and-tire combination.
How does tire size affect the appearance of a 2020 Infiniti Trucks QX60?
Tire size has a clear effect on the appearance of a 2020 Infiniti Trucks QX60 because the two fitments pair with different wheel diameters. A 235/55R20 works with a 20-inch wheel, while a 235/65R18 works with an 18-inch wheel. Each creates a different visual balance between wheel face and sidewall height.
Appearance should follow correct fitment rather than override it. Choosing the wrong size for the wheel will not preserve the QX60’s intended look and can create mounting problems immediately. For owners refreshing the vehicle cosmetically, the best approach is to confirm the existing wheel package first, then select replacement tires that maintain a clean, properly proportioned presentation.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2020 Infiniti Trucks QX60?
Yes, modifications can affect tire fitment on a 2020 Infiniti Trucks QX60. Aftermarket wheels, suspension changes, lowering, spacer use, or body alterations can all change how a 235/65R18 or 235/55R20 tire sits in the wheel opening. Even when the tire size is correct on paper, the vehicle’s altered setup can change clearance.
That is why a modified QX60 should be checked for wheel diameter, wheel width, steering travel, and fender or suspension clearance before replacement tires are chosen. Uneven wear can also point to alignment changes after modifications. Confirming the actual setup on the vehicle is more useful than relying only on trim-based fitment assumptions.
What should I inspect before driving a 2020 Infiniti Trucks QX60 on new tires?
Before driving a 2020 Infiniti Trucks QX60 on new tires, inspect the wheel size, lug hardware, tire pressure, and the clearance around the fenders and suspension. It is also wise to look at alignment-related wear on the old tires, since unusual wear patterns can signal issues that should be corrected before the new set sees regular use.
A road-ready check should also include valve stems, tread seating, and any vibration during the first miles of driving. On a vehicle that has sat for periods or changed owners, inspect the suspension and braking condition as well. Starting with the correct 18-inch or 20-inch fitment and a sound chassis helps the new tires perform as intended.
How often should tires on a 2020 Infiniti Trucks QX60 be inspected?
Tires on a 2020 Infiniti Trucks QX60 should be inspected regularly, not only at service intervals. A quick visual check for cuts, bulges, uneven wear, embedded debris, and pressure loss is worthwhile throughout normal use. This matters whether the vehicle is running 235/65R18 or 235/55R20, since both depend on proper condition and inflation to wear evenly.
A closer inspection becomes especially important before longer trips or after the vehicle has been parked for an extended period. Looking at sidewall condition, tread depth, and any signs of slow air loss can catch problems early. Rotations, alignment checks, and pressure checks also help preserve ride quality and extend the useful life of the tire set.
