The 2019 Infiniti Trucks QX60 sits in the modern luxury crossover class, blending family-sized space with a more premium road-going character than many mainstream three-row SUVs. For owners, tire choice is less about vintage-style construction and more about confirming the exact wheel setup already on the vehicle. This QX60 uses radial tires in either 235/65R18 or 235/55R20, depending on the wheel package. Because both the Luxe and Pure can be found with either size, the real starting point is verifying whether the vehicle has 18-inch or 20-inch rims. From there, the focus shifts to matching the proper metric size, load suitability, and everyday road-use priorities.
Which Tire Size Is Right for The 2019 Infiniti Trucks QX60
The 2019 Infiniti Trucks QX60 uses two primary tire sizes, and the correct choice depends first on wheel diameter. Both 235/65R18 and 235/55R20 are radial metric sizes, and both appear across the covered sub-models. Before comparing tire options, confirm whether the vehicle is equipped with 18-inch or 20-inch rims, especially if wheels have been changed at any point.
235/55R20 is a metric radial size in which 235 identifies the nominal section width in millimeters, 55 is the aspect ratio, R denotes radial construction, and 20 is the rim diameter in inches. On the 2019 Infiniti Trucks QX60, this size belongs to vehicles using the 20-inch wheel package rather than the 18-inch setup. Its overall dimensions stay very close to the alternate QX60 size, but the shorter sidewall gives it a different sizing profile. This is the size to evaluate when the vehicle already has 20-inch wheels and clearance should be checked against that exact setup.
235/65R18 is a metric radial size where 235 is the nominal width in millimeters, 65 is the aspect ratio, R indicates radial construction, and 18 identifies the rim diameter in inches. For the 2019 Infiniti Trucks QX60, this size applies to vehicles equipped with 18-inch wheels. Its dimensions are very similar in overall height to the 20-inch fitment, but it is built around a different rim diameter and cannot be selected by size preference alone. This is the appropriate starting point when the vehicle retains its 18-inch wheel arrangement.
Tire fitment on the 2019 Infiniti Trucks QX60 is straightforward in one sense and easy to misread in another. Both the Luxe and Pure can use either primary tire size, so the key step is confirming the actual wheel diameter on the vehicle rather than assuming the sub-model alone determines fitment.

2019 Infiniti Trucks QX60 Luxe
The 2019 Infiniti Trucks QX60 Luxe can use either of the two primary radial tire sizes, depending on whether it has 18-inch or 20-inch wheels. Tire selection starts with verifying the current rim diameter, then choosing the matching metric size for the vehicle's existing wheel setup.
The 2019 Infiniti Trucks QX60 Pure also appears with both primary radial tire sizes rather than one fixed sub-model-only fitment. That makes wheel confirmation more important than trim name alone, especially on vehicles that may have had wheels changed since new.
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 questions for the 2019 Infiniti Trucks QX60 usually center on identifying the correct metric tire size, confirming 18-inch versus 20-inch rim fitment, and understanding how wheel changes, maintenance, and vehicle setup can affect tire selection.
Tire Size & Fitment
What tire size fits a 2019 Infiniti Trucks QX60?
The 2019 Infiniti Trucks QX60 uses one of two radial tire sizes: 235/65R18 or 235/55R20. Both sizes are correct for this model, but they are tied to different wheel diameters, so the vehicle does not use them interchangeably on the same rim.
The practical first step is checking the wheel currently on the vehicle. An 18-inch wheel requires 235/65R18, while a 20-inch wheel requires 235/55R20. If the QX60 has aftermarket wheels or a previous owner changed the package, confirm the actual rim diameter before selecting tires.
What size rim does a 2019 Infiniti Trucks QX60 use?
A 2019 Infiniti Trucks QX60 can use either an 18-inch rim or a 20-inch rim, depending on the setup. The 235/65R18 tire matches the 18-inch wheel, and the 235/55R20 tire matches the 20-inch wheel.
Rim diameter is the key fitment checkpoint on this vehicle because both tire sizes appear across the QX60 range. Looking at the current tire sidewall or measuring the wheel is more reliable than assuming fitment from trim alone, particularly if the vehicle has been modified or updated with different wheels.
Do all 2019 Infiniti Trucks QX60 sub-models use the same tire size?
No. The 2019 Infiniti Trucks QX60 Luxe and Pure can both be found with either 235/65R18 or 235/55R20. That means the sub-model name by itself does not narrow the fitment to one guaranteed tire size.
The real deciding factor is the wheel package installed on the vehicle. Before replacing tires, confirm whether the QX60 has 18-inch or 20-inch rims and match the tire size to that wheel diameter. This matters even more on used vehicles where wheel swaps are fairly common.
Choosing the Right Tire
What should I consider when choosing a tire for a 2019 Infiniti Trucks QX60?
Start with the exact tire size already matched to the vehicle's wheel diameter: 235/65R18 for 18-inch rims or 235/55R20 for 20-inch rims. Both are radial metric sizes, so the main selection issue is not construction type but getting the correct size for the wheel that is actually on the QX60.
After size is confirmed, compare the tire's load suitability, overall fit on the existing wheel, and the kind of driving the vehicle sees most often. Daily commuting, highway travel, and seasonal use all influence the final choice, but none of those factors replaces the need to match the correct size first.
How do I choose between the available 2019 Infiniti Trucks QX60 tire sizes?
The two QX60 tire sizes are not alternate style choices for the same wheel. 235/65R18 is for 18-inch rims, while 235/55R20 is for 20-inch rims. The deciding factor is the wheel diameter already fitted to the vehicle, not which size sounds preferable on paper.
That distinction matters because both sizes have similar overall dimensions but mount to different rims. A buyer choosing tires should verify the sidewall marking on the current tires or inspect the wheel directly. Once the wheel size is confirmed, tire shopping becomes a matter of selecting the right specification within that correct size.
What rim-fitment details should I compare when choosing 2019 Infiniti Trucks QX60 tires?
The most important rim-fitment detail is diameter. A 2019 Infiniti Trucks QX60 using 235/65R18 needs an 18-inch rim, and one using 235/55R20 needs a 20-inch rim. Selecting the wrong diameter prevents proper mounting regardless of how close the other dimensions may seem.
Wheel condition and actual vehicle setup also matter. If the QX60 has replacement wheels, confirm that their size and fitment match the tire being considered, then check for normal clearance at the fenders and suspension. This is especially worthwhile when the vehicle's wheel package may no longer be original.
Restoration & Appearance
Does correct tire fitment matter for a 2019 Infiniti Trucks QX60 restoration or refurbishment?
Yes. Even on a modern luxury crossover like the 2019 Infiniti Trucks QX60, proper tire fitment is part of presenting the vehicle as intended and keeping its road manners consistent. The right starting point is using 235/65R18 on 18-inch rims or 235/55R20 on 20-inch rims.
A refurbishment often includes wheels, brakes, suspension parts, and alignment work, so tire selection should be checked against the actual hardware on the vehicle. Owners aiming for an authentic appearance should also verify wheel style and package details through vehicle-specific references rather than assuming every QX60 used the same setup.
How does tire size affect the appearance of a 2019 Infiniti Trucks QX60?
Tire size has a visible effect because the QX60 uses either an 18-inch or 20-inch wheel package. Even though 235/65R18 and 235/55R20 are close in overall diameter, the sidewall proportion changes the visual balance between tire and wheel.
That makes it important to match the tire to the wheel package the vehicle actually carries. Owners refreshing the vehicle's look often want a consistent, properly filled wheel opening without unintended mismatch. Keeping the correct size for the installed rim helps preserve that balanced appearance and avoids obvious fitment errors.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2019 Infiniti Trucks QX60?
Yes. A 2019 Infiniti Trucks QX60 may have had aftermarket wheels, suspension changes, or other alterations that affect which tire size belongs on it. Even though the primary sizes are 235/65R18 and 235/55R20, modifications can change the wheel diameter or the clearance available around the tire.
That is why the vehicle should be checked as it sits today rather than selected by trim name alone. Wheel diameter, wheel width, ride height, and fender or suspension clearance all deserve a quick review before ordering replacements, especially if the QX60 was purchased used or has been personalized.
What should I inspect before driving a 2019 Infiniti Trucks QX60 on new tires?
Check that the tire size matches the wheel diameter on the vehicle, then inspect inflation pressure, bead seating, and overall condition of the wheels. A quick visual review for damage, rubbing marks, or uneven spacing around the tire is also worthwhile before regular road use.
After installation, monitor for vibration, pulling, or unexpected contact during turning and suspension movement. It also helps to recheck pressure after the first drives and keep an eye on tread wear as the tires settle into service. Those steps help confirm that the QX60's tire and wheel setup is behaving normally.
How often should tires on a 2019 Infiniti Trucks QX60 be inspected?
Tires on a 2019 Infiniti Trucks QX60 should be inspected regularly, not just when tread looks worn. A visual check for cuts, punctures, sidewall cracking, bulges, and uneven wear is smart during routine vehicle care, and pressure should be monitored consistently as part of normal ownership.
Inspection becomes even more important when the vehicle is used less often, carries family road-trip duty, or has recently had wheel or suspension work. Looking over the tires before longer drives can catch slow air loss or developing wear problems early, helping the QX60 stay predictable and comfortable on the road.
