The 2025 Infiniti Trucks QX60 blends three-row luxury crossover comfort with the larger-wheel, modern-road manners buyers expect in a current premium family vehicle. Its tire fitment is less about vintage-style construction choices and more about matching the correct wheel-and-trim combination. This QX60 uses radial tires in two exact sizes, 255/50R20 and 255/60R18, depending on sub-model. That means the key decision is confirming whether the vehicle is a Pure or one of the 20-inch-wheel trims before comparing tire choices. Once the size is confirmed, the focus shifts to maintaining the intended ride, proportions, and clearance with the correct modern metric radial fitment.
Which Tire Size Is Right for The 2025 Infiniti Trucks QX60
The 2025 Infiniti Trucks QX60 uses two primary tire sizes, and the right one depends on sub-model and wheel diameter. Both are modern metric radial sizes, but one fits an 18-inch rim and the other fits a 20-inch rim. Before choosing a tire, the first step is confirming the exact trim and verifying which wheel package is actually on the vehicle.
255/50R20 is a metric radial size in which 255 identifies nominal section width in millimeters, 50 is the aspect ratio, R indicates radial construction, and 20 is the rim diameter in inches. On the 2025 Infiniti Trucks QX60, this size is used on 20-inch-wheel trims rather than across the full model line. Its dimensions keep the vehicle in the intended overall tire height range while pairing with a larger-diameter wheel. This is the size to evaluate when the QX60 is an Autograph, Luxe, or Sensory, or whenever the vehicle is already equipped with 20-inch wheels.
255/60R18 is a metric radial size where 255 denotes nominal section width in millimeters, 60 is the aspect ratio, R marks radial construction, and 18 is the rim diameter in inches. For the 2025 Infiniti Trucks QX60, this size applies to the 18-inch-wheel configuration rather than the higher-wheel-diameter trims. Its overall diameter stays very close to the 20-inch fitment, but it is built for a different wheel. This is the size to use when the vehicle is a Pure or when wheel inspection confirms an 18-inch setup.
Tire fitment on the 2025 Infiniti Trucks QX60 depends on the exact sub-model because wheel diameter changes across the lineup. Confirming trim level matters here, since three sub-models use the 20-inch radial size while the Pure uses the 18-inch radial size.

2025 Infiniti Trucks QX60 Autograph
The 2025 Infiniti Trucks QX60 Autograph uses the 255/50R20 radial tire size. Tire selection starts with confirming the 20-inch wheel setup, then choosing a replacement that preserves the intended overall proportions and clearance of this trim.
The 2025 Infiniti Trucks QX60 Luxe uses the 255/50R20 radial tire size. That keeps the fitment process straightforward as long as the vehicle still has its 20-inch wheels, so the main concern is matching the correct modern metric radial size.
The 2025 Infiniti Trucks QX60 Pure uses the 255/60R18 radial tire size. This makes wheel confirmation especially important, since the Pure differs from the 20-inch-wheel trims and should be matched to the correct 18-inch fitment before comparing replacement tires.
The 2025 Infiniti Trucks QX60 Sensory uses the 255/50R20 radial tire size. Once the 20-inch wheel package is confirmed, the buyer's task is simply choosing the right replacement tire within that exact modern radial specification.
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
QX60 owners usually need to confirm trim-based tire size first, then sort through wheel diameter, modern metric radial fitment, replacement choice, and maintenance checks before regular road use.
Tire Size & Fitment
What tire size fits a 2025 Infiniti Trucks QX60?
The 2025 Infiniti Trucks QX60 uses one of two tire sizes: 255/50R20 or 255/60R18. Both are radial tires, but they do not apply across every trim. Autograph, Luxe, and Sensory use 255/50R20, while Pure uses 255/60R18.
The practical difference is wheel diameter. A 255/50R20 tire belongs on a 20-inch rim, and a 255/60R18 tire belongs on an 18-inch rim. Before replacing tires, confirm the exact sub-model and check the actual wheel size on the vehicle, especially if the QX60 has had wheel changes since new.
What size rim does a 2025 Infiniti Trucks QX60 use?
A 2025 Infiniti Trucks QX60 uses either an 18-inch rim or a 20-inch rim, depending on sub-model. The 255/60R18 fitment uses an 18-inch wheel, while the 255/50R20 fitment uses a 20-inch wheel. Both are modern radial configurations.
Rim diameter is the first fitment checkpoint because the two QX60 tire sizes are tied to different wheels. Tire replacement should never start with section width alone. Confirm the wheel diameter cast or stamped on the wheel, or verify the existing tire size, before selecting a replacement for the vehicle.
Do all 2025 Infiniti Trucks QX60 sub-models use the same tire size?
No. The 2025 Infiniti Trucks QX60 uses different tire sizes across its sub-models. Autograph, Luxe, and Sensory use 255/50R20, while the Pure uses 255/60R18. Both are radial sizes, but they are matched to different wheel diameters.
That distinction matters because the two sizes are not simply alternate labels for the same wheel. A buyer should identify the exact trim before comparing tires, then confirm the vehicle still has the correct wheel package. That is especially important on used QX60s, where wheels may have been swapped after delivery.
Choosing the Right Tire
What should I consider when choosing a tire for a 2025 Infiniti Trucks QX60?
Start with the exact size that matches the QX60's trim and wheel diameter. This vehicle uses either 255/50R20 or 255/60R18, and both are radial metric sizes. Choosing the correct size matters more than comparing tread or brand categories too early.
After size is confirmed, look at the vehicle's actual wheel setup, intended use, and overall condition. A daily-driven family crossover needs a tire that matches the existing wheel package and preserves proper clearance. If the QX60 has aftermarket wheels or suspension changes, recheck dimensions before assuming the original trim-based size still applies.
How do I choose between the available 255/50R20 and 255/60R18 tires for a 2025 Infiniti Trucks QX60?
The choice is not between 255/50R20 and 255/60R18 as interchangeable options. Each size belongs to a specific QX60 wheel and trim configuration. 255/50R20 is used on Autograph, Luxe, and Sensory, while 255/60R18 is used on Pure.
Once the correct size is established, compare replacement tires within that exact fitment rather than crossing between the two. Even though their overall diameters are very close, they mount on different rim diameters. Wheel size, present vehicle setup, and clearance around suspension and body components should all be checked before any change.
What rim-fitment details matter when choosing 2025 Infiniti Trucks QX60 tires?
The most important rim-fitment detail is diameter. A 2025 Infiniti Trucks QX60 uses either an 18-inch or 20-inch wheel, and the tire must match that exact rim size. The 255/60R18 and 255/50R20 sizes are both metric radials, but they are built for different wheels.
Wheel changes can complicate replacement, especially on vehicles bought used. Checking the current wheel size before purchase helps avoid ordering the right width and profile on the wrong rim diameter. It is also wise to confirm that wheel width, brake clearance, and suspension clearance remain appropriate if the vehicle no longer wears its original-style wheels.
Restoration & Appearance
Does correct tire fitment matter for a 2025 Infiniti Trucks QX60 restoration or refurbishment?
Yes. Even on a modern luxury crossover like the 2025 Infiniti Trucks QX60, correct tire fitment matters when the goal is a clean, proper refurbishment. The vehicle uses trim-based sizes, with 255/50R20 on Autograph, Luxe, and Sensory, and 255/60R18 on Pure.
Using the right size helps preserve the intended stance and wheel-to-tire relationship for that specific trim. It also reduces the chance of clearance issues caused by mixing wheel packages. Owners aiming for an as-delivered appearance should verify the vehicle's original wheel setup before replacing tires on a repaired or newly acquired QX60.
How does tire size affect the appearance of a 2025 Infiniti Trucks QX60?
Tire size has a visible effect on the 2025 Infiniti Trucks QX60 because the model uses two wheel-and-tire combinations with different profiles. The 255/50R20 setup presents a shorter sidewall on a larger wheel, while the 255/60R18 setup pairs a taller sidewall with an 18-inch rim.
That difference means appearance should follow the trim's intended wheel package rather than personal preference alone. Installing a tire meant for the wrong rim diameter changes the visual balance immediately and creates a fitment problem. A refurbishment-minded buyer should match the tire to the wheel that actually belongs on that specific QX60 sub-model.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2025 Infiniti Trucks QX60?
Yes. Modifications can affect tire fitment on a 2025 Infiniti Trucks QX60 even when the replacement tire matches one of the original sizes. Wheel swaps, offset changes, suspension lowering, or altered ride height can change clearance around the fenders, struts, and steering components.
That matters because this QX60 already has trim-based fitment differences tied to either 18-inch or 20-inch wheels. A vehicle wearing aftermarket wheels may no longer match its original sub-model sizing assumptions. Before replacing tires, inspect the current setup carefully and confirm both rim diameter and clearance through the full steering range.
What should I inspect before driving a 2025 Infiniti Trucks QX60 on new tires?
Before road use, inspect tire pressure, wheel torque, visible bead seating, and clearance around suspension and body components. A 2025 Infiniti Trucks QX60 should also be checked to confirm the new tires match the vehicle's actual wheel diameter, since this model uses either 255/60R18 or 255/50R20.
A short test drive should be followed by another visual inspection for rubbing, unusual vibration, or air loss. It is also smart to check alignment and overall suspension condition if the old tires showed uneven wear. Those steps help protect the new tires and confirm the QX60 is ready for regular road use.
How often should tires on a 2025 Infiniti Trucks QX60 be inspected?
Tires on a 2025 Infiniti Trucks QX60 should be inspected regularly, not just when tread looks low. Frequent visual checks help catch uneven wear, punctures, sidewall damage, or air-pressure loss early. That is especially useful on a trim-based fitment vehicle where the wrong replacement size can also create abnormal wear patterns.
A practical routine is to inspect the tires during pressure checks and before longer trips. Pay attention to shoulder wear, cuts, bulges, and any signs of rubbing after wheel or suspension changes. Keeping the correct size on the correct rim is only part of the job; ongoing inspection is what keeps the fitment working properly.
