The 2024 Infiniti Trucks QX60 sits in the modern luxury three-row crossover category, where quiet road manners, confident highway use, and a polished appearance all matter as much as day-to-day practicality. For this model, tire selection starts with trim-specific fitment rather than one universal size. The QX60 uses radial construction, with 255/50R20 on Autograph, Luxe, and Sensory models, while Pure models use 255/60R18. That means the main choice is confirming the exact sub-model and wheel diameter first, then comparing available tire options in the correct metric radial size. Owners should also account for any wheel changes or suspension modifications before replacing tires.
Which Tire Size Is Right for The 2024 Infiniti Trucks QX60
Two tire sizes apply to the 2024 Infiniti Trucks QX60, and the correct choice depends on the sub-model and wheel diameter. Autograph, Luxe, and Sensory models use a 20-inch fitment, while the Pure uses an 18-inch fitment. Because both sizes are radial and very close in overall diameter, the first step is confirming which wheels are actually on the vehicle before comparing tire choices.
255/50R20 is a modern metric radial size in which 255 identifies the nominal section width in millimeters, 50 is the aspect ratio, R denotes radial construction, and 20 is the rim diameter in inches. On the 2024 Infiniti Trucks QX60, this size is used on specific higher-trim applications and keeps the fitment tied to a 20-inch wheel. Its practical role is straightforward: match it to the correct sub-model and wheel setup, then compare tire choices within that size for road use, appearance, and overall vehicle setup rather than treating it as interchangeable with the 18-inch fitment.
255/60R18 is also a modern metric radial size, using the same 255-millimeter nominal width but a taller 60-series profile on an 18-inch rim. For the 2024 Infiniti Trucks QX60, this size belongs to a specific sub-model configuration, so it should be selected by confirmed trim and wheel diameter rather than by model name alone. Because its overall diameter is very close to the 20-inch fitment, buyers sometimes assume the sizes are broadly interchangeable, but the correct decision still depends on the actual wheel size and the vehicle's current setup.
Sub-model fitment matters on the 2024 Infiniti Trucks QX60 because not every trim uses the same tire size. Three trims share the 20-inch radial fitment, while one trim uses an 18-inch radial fitment, so identifying the exact sub-model helps narrow the tire search quickly and avoids selecting the wrong wheel diameter.

2024 Infiniti Trucks QX60 Autograph
The 2024 Infiniti Trucks QX60 Autograph uses the 255/50R20 radial tire size. Tire selection for this trim starts with confirming the 20-inch wheel setup, then choosing the right replacement in that metric radial size for the vehicle's intended road use and overall setup.
The 2024 Infiniti Trucks QX60 Luxe also uses the 255/50R20 radial fitment. That keeps tire choice centered on matching the 20-inch wheel diameter correctly and checking whether the vehicle still carries its original wheel configuration before replacement.
The 2024 Infiniti Trucks QX60 Pure uses the 255/60R18 radial tire size rather than the 20-inch fitment found on other trims. That makes wheel diameter the key verification point before buying tires, especially if the vehicle has changed hands or has been fitted with different wheels.
The 2024 Infiniti Trucks QX60 Sensory uses the 255/50R20 radial tire size. For this trim, the main tire decision is not between primary sizes but between replacement options within the correct 20-inch metric radial fitment and the vehicle's actual wheel 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
These FAQs focus on the 2024 Infiniti Trucks QX60 tire sizes, trim-based wheel fitment, and the checks that matter before replacement. They also cover practical selection, maintenance, and road-use questions for owners verifying 18-inch versus 20-inch setups.
Tire Size & Fitment
What tire size fits a 2024 Infiniti Trucks QX60?
The 2024 Infiniti Trucks QX60 uses two tire sizes: 255/50R20 and 255/60R18. The 255/50R20 size is used on Autograph, Luxe, and Sensory models, while the Pure uses 255/60R18. Both are radial tire sizes, but they are tied to different wheel diameters and trim levels rather than being one universal fitment for every QX60.
The practical first step is confirming the exact sub-model and checking the wheels currently on the vehicle. A QX60 with replacement wheels or a trim-to-wheel change may no longer match the original setup, so the safest approach is to verify the installed rim diameter before selecting tires.
What size rim does a 2024 Infiniti Trucks QX60 use?
A 2024 Infiniti Trucks QX60 uses either an 18-inch rim or a 20-inch rim, depending on the sub-model. Pure models use the 255/60R18 size on an 18-inch wheel, while Autograph, Luxe, and Sensory models use the 255/50R20 size on a 20-inch wheel. The tire size itself tells you the intended rim diameter in the final number.
Because the QX60 has two factory wheel diameters across its trims, it is important not to rely on the model name alone when ordering tires. Reading the current tire sidewall and confirming the wheel size on the vehicle can prevent buying the right width and profile in the wrong diameter.
Do all 2024 Infiniti Trucks QX60 sub-models use the same tire size?
No, not all 2024 Infiniti Trucks QX60 sub-models use the same tire size. Autograph, Luxe, and Sensory models share the 255/50R20 radial fitment, while the Pure uses 255/60R18. That means tire fitment varies by sub-model, even though the two sizes are close in overall diameter and share the same nominal section width.
This difference matters because the wheel diameter changes with the tire size, and that determines what can actually be mounted on the vehicle. If the QX60 has been fitted with take-off wheels, accessory wheels, or another trim's wheel package, check the actual tire size on the vehicle before replacement.
Choosing the Right Tire
What should I consider when choosing a 255/50R20 tire for a 2024 Infiniti Trucks QX60?
Start by confirming that the QX60 is an Autograph, Luxe, or Sensory model, or that it currently has 20-inch wheels installed. The 255/50R20 size is a metric radial fitment, so the key considerations are matching the correct size and using a tire intended for the vehicle's road-going luxury crossover role rather than choosing by appearance alone.
It also helps to inspect how the vehicle is actually used, whether that means daily driving, long highway trips, or mostly local family use. Wheel condition, prior curb damage, and any suspension changes should be checked at the same time so the new tires match the QX60's current setup instead of only its original trim label.
What should I consider when choosing a 255/60R18 tire for a 2024 Infiniti Trucks QX60?
For a 2024 Infiniti Trucks QX60, the 255/60R18 size applies to the Pure trim and uses an 18-inch wheel. Choosing correctly starts with verifying that the vehicle still has that 18-inch setup, then selecting a tire in the exact same metric radial size so the fitment stays consistent with the wheel diameter and intended profile.
Buyers should also think about the vehicle's actual condition and use before replacing tires. An 18-inch wheel package that has been changed from stock, paired with suspension modifications, or used with unevenly worn old tires deserves a closer look so the replacement choice matches the QX60 as it sits today.
How do I choose between the available tire sizes for a 2024 Infiniti Trucks QX60?
The right size is determined by the QX60's sub-model and wheel diameter, not by personal preference alone. Autograph, Luxe, and Sensory models use 255/50R20, while Pure models use 255/60R18. Since both sizes are primary fitments for different trims, the choice is really about matching the actual wheel package already on the vehicle.
A quick visual check can save time: read the sidewall on the current tires and confirm whether the wheels are 18-inch or 20-inch. That step matters especially on used vehicles, because a trim may now carry different wheels than it left with, and the tire size must follow the installed rim diameter.
Restoration & Appearance
Does correct tire fitment matter for a 2024 Infiniti Trucks QX60?
Yes, correct tire fitment matters on a 2024 Infiniti Trucks QX60 because the vehicle uses two distinct metric radial sizes tied to different wheel diameters. Using the proper size helps preserve the intended relationship between the tire, the wheel, and the vehicle's stance. On this model, the first fitment question is always whether the QX60 has the 18-inch or 20-inch setup.
Even on a newer luxury crossover, appearance and fitment go together. A tire that matches the installed wheel diameter and trim-specific setup will generally look more at home on the vehicle, while a mismatch can create unnecessary mounting problems or an off-balance presentation once the tires are installed.
How does tire size affect the appearance of a 2024 Infiniti Trucks QX60?
Tire size influences how much sidewall is visible and which wheel diameter defines the QX60's overall look. The 255/50R20 fitment places the tire on a 20-inch wheel with a lower-profile sidewall, while the 255/60R18 fitment uses an 18-inch wheel with a taller sidewall. Both remain close in overall diameter, but they present the vehicle differently.
That visual difference is one reason the wheel package should be confirmed before replacing tires, especially on a used vehicle. A QX60 wearing another trim's wheels may still function normally, but the replacement tire should match the installed setup so the proportions stay consistent from both a fitment and appearance standpoint.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2024 Infiniti Trucks QX60?
Yes, modifications can affect tire fitment on a 2024 Infiniti Trucks QX60 even when the replacement tire size matches one of the original trim fitments. Wheel changes, altered offsets, suspension lowering, or non-original springs can all change how much space is available around the tire. That matters whether the vehicle uses 255/50R20 or 255/60R18.
A QX60 with aftermarket wheels should be checked for both rim diameter and overall wheel dimensions before new tires are installed. Clearance at full steering lock, fender space, and any signs of rubbing are worth inspecting so the chosen tire size works with the vehicle's actual configuration rather than the trim name alone.
What should I inspect before driving a 2024 Infiniti Trucks QX60 on new tires?
Before driving a 2024 Infiniti Trucks QX60 on new tires, inspect the wheels for damage, confirm the tire size matches the installed rim diameter, and check that the tires are properly inflated. It also helps to look over the suspension and steering for obvious wear, since alignment or component issues can shorten tire life quickly on a modern crossover.
After installation, recheck for clearance while turning the steering from lock to lock and watch for any unusual vibration once the vehicle is on the road. Early checks are especially useful on a QX60 that has changed wheel packages, because a size that is correct for one trim may not belong on another wheel setup.
How often should tires on a 2024 Infiniti Trucks QX60 be inspected?
Tires on a 2024 Infiniti Trucks QX60 should be inspected regularly rather than only at replacement time. A quick visual check for uneven wear, cuts, punctures, sidewall damage, or air loss is worthwhile throughout normal use, and a closer inspection makes sense before longer trips. That applies whether the vehicle uses the 18-inch or 20-inch fitment.
Routine inspection is especially important on a heavier, family-oriented crossover that may spend a lot of time on the highway or carrying passengers and cargo. Keeping an eye on tread condition and inflation helps catch problems early, while periodic confirmation of wheel and suspension condition can explain unusual wear before it becomes expensive.
