The 2021 Infiniti Trucks QX80 sits in the modern full-size luxury SUV class, blending upscale road presence with the tall stance and substantial wheel-and-tire package buyers expect in this segment. For tire selection, the key question is not construction, since both original fitments are radial, but identifying which wheel package your QX80 carries. Luxe models use 275/60R20, while Premium Select and Sensory models use 275/50R22. That makes sub-model and rim diameter confirmation the first step before comparing replacement options. Once the correct size is confirmed, the focus shifts to maintaining proper proportions, wheel compatibility, and the road manners expected from a large luxury SUV.
Which Tire Size Is Right for The 2021 Infiniti Trucks QX80
Two tire sizes apply to the 2021 Infiniti Trucks QX80, and the difference comes down to sub-model and wheel diameter rather than tire construction. Luxe uses a 20-inch fitment with 275/60R20, while Premium Select and Sensory use a 22-inch fitment with 275/50R22. Before choosing a tire, confirm the exact sub-model or check the wheel diameter already on the vehicle.
In 275/60R20, the 275 identifies nominal section width in millimeters, the 60 is the aspect ratio, the R marks radial construction, and the 20 is the wheel diameter in inches. This is a modern radial size used on the 2021 Infiniti Trucks QX80 Luxe, giving the vehicle a taller sidewall on a 20-inch wheel. That extra sidewall is part of what distinguishes it from the QX80's 22-inch package. For replacement shopping, the practical step is matching this exact size to the Luxe setup rather than assuming every QX80 uses the same wheel and tire combination.
In 275/50R22, the 275 indicates nominal section width in millimeters, the 50 is the aspect ratio, the R denotes radial construction, and the 22 identifies the wheel diameter in inches. This size belongs to 2021 Infiniti Trucks QX80 Premium Select and Sensory models, which use the larger 22-inch wheel package. Even though the width matches the 20-inch fitment, the shorter sidewall and different rim diameter make this a distinct setup. Choosing this size starts with confirming that the vehicle is one of the 22-inch sub-models or has the correct wheel package already installed.
Tire fitment on the 2021 Infiniti Trucks QX80 varies by sub-model, so identifying the exact trim matters before selecting a replacement. The difference is straightforward: Luxe uses one size on a 20-inch wheel, while Premium Select and Sensory share another size on a 22-inch wheel.

2021 Infiniti Trucks QX80 Luxe
The 2021 Infiniti Trucks QX80 Luxe uses a 275/60R20 radial tire, making it the 20-inch wheel fitment within the QX80 lineup. Tire selection for this sub-model starts with staying within that size and confirming the vehicle has not been changed to a different wheel package.
The 2021 Infiniti Trucks QX80 Premium Select uses a 275/50R22 radial tire, placing it on the larger 22-inch wheel setup. That means replacement shopping should focus on the correct 22-inch size and not the QX80 Luxe fitment, even though both share the same nominal tread width.
The 2021 Infiniti Trucks QX80 Sensory also uses a 275/50R22 radial tire on a 22-inch wheel package. Because it shares its fitment with Premium Select, the main consideration is verifying that the current wheels remain the original diameter if the vehicle has seen any wheel changes.
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
Tire questions on the 2021 Infiniti Trucks QX80 usually come down to sub-model fitment, 20-inch versus 22-inch wheel packages, and confirming the right metric radial size before replacement. The FAQs below focus on size meaning, wheel fitment, selection priorities, and practical checks before road use.
Tire Size & Fitment
What tire size fits a 2021 Infiniti Trucks QX80?
The 2021 Infiniti Trucks QX80 uses two tire sizes depending on sub-model. QX80 Luxe uses 275/60R20, while QX80 Premium Select and QX80 Sensory use 275/50R22. Both are radial tire fitments, but they are tied to different wheel diameters and should not be treated as the same setup.
The practical first step is confirming whether the vehicle has the 20-inch or 22-inch wheel package. A buyer who starts with the sub-model and wheel diameter will narrow the fitment quickly, while anyone shopping only by model name can easily end up comparing the wrong size.
What size rim does a 2021 Infiniti Trucks QX80 use?
A 2021 Infiniti Trucks QX80 uses either a 20-inch or 22-inch rim, depending on sub-model. Luxe models use the 20-inch fitment paired with 275/60R20 tires, while Premium Select and Sensory models use the 22-inch fitment paired with 275/50R22 tires.
Rim diameter should be verified before ordering tires because the two QX80 fitments are not interchangeable by size code alone. Checking the sidewall marking on the current tire and confirming the actual wheel diameter helps prevent selecting a tire meant for the other sub-model's wheel package.
Do all 2021 Infiniti Trucks QX80 sub-models use the same tire size?
No. The 2021 Infiniti Trucks QX80 Luxe uses 275/60R20, while the Premium Select and Sensory use 275/50R22. All three sub-models use radial tires, but the lineup is split between a 20-inch wheel package and a 22-inch wheel package.
That difference matters because the correct tire choice starts with the exact trim or the actual wheels on the vehicle. If the QX80 has had aftermarket wheel changes, rely on the wheel and tire currently fitted only after confirming that the setup was selected with proper diameter, clearance, and load considerations in mind.
Choosing the Right Tire
What should I consider when choosing a tire for a 2021 Infiniti Trucks QX80?
Start with the correct size for the specific 2021 Infiniti Trucks QX80 sub-model. Luxe requires 275/60R20, while Premium Select and Sensory require 275/50R22, and both fitments are radial. Getting the right rim diameter matters first, since a 20-inch tire and a 22-inch tire serve different wheel packages.
After size is confirmed, compare tire choices based on how the QX80 is used. A large luxury SUV benefits from matching the intended balance of ride quality, road manners, and appearance, while also confirming the wheel setup has not been altered from the original sub-model fitment.
How do I choose between the 20-inch and 22-inch tire fitments on a 2021 Infiniti Trucks QX80?
The choice is determined by the QX80's wheel package, not by preference alone. The 2021 Infiniti Trucks QX80 Luxe uses 275/60R20 on a 20-inch rim, while Premium Select and Sensory use 275/50R22 on a 22-inch rim. Each size is tied to its own sub-model configuration.
That means the real task is confirming what wheels are on the vehicle now. If the QX80 still carries its original setup, the sub-model tells the story; if wheels have been changed, check the actual rim diameter and the current tire markings before comparing replacement tires.
What does 275/60R20 or 275/50R22 mean on a 2021 Infiniti Trucks QX80?
Both are modern metric radial tire sizes. In each size, 275 is the nominal width in millimeters, the middle number is the aspect ratio, R means radial construction, and the final number is the wheel diameter in inches. The difference is that one tire fits a 20-inch wheel and the other fits a 22-inch wheel.
For a QX80 owner, those numbers are more than a label. They identify the correct wheel diameter and sidewall profile for the sub-model's setup, so matching the full size code is more useful than focusing only on width when it is time to replace tires.
Restoration & Appearance
Does correct tire fitment matter for the appearance of a 2021 Infiniti Trucks QX80?
Yes. On a 2021 Infiniti Trucks QX80, the visual stance is closely tied to whether the SUV wears its correct 20-inch or 22-inch wheel-and-tire package. Luxe uses 275/60R20, while Premium Select and Sensory use 275/50R22, so the sidewall profile and wheel presence change with the sub-model fitment.
Appearance also depends on keeping the tire proportion consistent with the vehicle's original package. A replacement tire in the correct size helps preserve the intended look, while an incorrect diameter or profile can alter how the QX80 sits and fills the wheel opening.
Which tire fitment should I keep for a factory-style 2021 Infiniti Trucks QX80 look?
A factory-style appearance starts with retaining the correct sub-model fitment. The 2021 Infiniti Trucks QX80 Luxe uses 275/60R20, and the Premium Select and Sensory use 275/50R22. Staying with the original size keeps the wheel-to-sidewall proportion in line with the SUV's intended presentation.
That does not automatically mean every replacement tire will look identical, since tread design and sidewall styling can vary across products. The safest visual approach is to confirm the original wheel diameter first, then compare replacement tires within that exact size rather than mixing fitments between QX80 trims.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2021 Infiniti Trucks QX80?
Yes. A 2021 Infiniti Trucks QX80 may have started with either a 20-inch or 22-inch wheel package, so aftermarket wheels, suspension changes, or altered ride height can change what tire size is currently appropriate. Even when the tire width remains similar, the wheel diameter and sidewall profile still matter.
Anyone replacing tires on a modified QX80 should verify the actual wheel diameter, wheel width, and available clearance before assuming the original sub-model fitment still applies. Steering clearance, suspension travel, and the vehicle's loaded stance are all worth checking when the setup differs from stock.
What should I inspect before driving a 2021 Infiniti Trucks QX80 on new tires?
Before road use, inspect basic installation and condition items such as proper inflation, valve condition, tread and sidewall integrity, and even seating of the tire on the wheel. On a 2021 Infiniti Trucks QX80, it is also important to confirm that the new tires match the correct size for the vehicle's 20-inch or 22-inch setup.
A quick walkaround should also include checking for rubbing at full steering lock and looking at fender and suspension clearance. Large luxury SUVs can mask fitment issues until they are loaded or turning, so a short, careful test drive is a useful final step after installation.
How often should tires on a 2021 Infiniti Trucks QX80 be inspected?
Tires on a 2021 Infiniti Trucks QX80 should be inspected regularly, not only when tread looks worn. Pressure, tread condition, cuts, bulges, irregular wear, and sidewall cracking are all worth checking, especially on a vehicle that may alternate between daily use and longer trips.
Routine inspection matters because a QX80 carries substantial size and weight, and its ride quality depends heavily on tire condition. Checking tires before road trips, after seasonal storage, and anytime handling or ride changes noticeably can help catch issues before they become a larger fitment or safety problem.
