The 2020 Infiniti Trucks QX80 blends full-size SUV presence with luxury touring character, making tire selection as much about correct fitment as overall appearance and road manners. As a modern body-on-frame luxury SUV, it sits in a category where wheel and tire package differences can change the look and stance significantly from one trim to another. For this exact QX80, the key fitment question is whether the vehicle uses 275/60R20 or 275/50R22, since both are radial sizes tied to different sub-models. That makes trim identification and wheel confirmation more important than broad brand comparison before narrowing down replacement choices.
Which Tire Size Is Right for The 2020 Infiniti Trucks QX80
The 2020 Infiniti Trucks QX80 uses two primary tire sizes, and the right one depends on the exact sub-model and wheel package. Both fitments are metric radial sizes, but they use different rim diameters: 20-inch wheels with 275/60R20 or 22-inch wheels with 275/50R22. Before choosing a replacement tire, confirm the trim level and verify the wheel diameter currently on the vehicle.
A 275/50R22 tire uses a 275-millimeter nominal section width, a 50-series aspect ratio, radial construction, and a 22-inch rim diameter. On the 2020 Infiniti Trucks QX80, this size belongs to sub-models equipped with the larger 22-inch wheel package, giving the vehicle a distinctly modern luxury-SUV presentation. Buyers looking at this size should focus first on correct 22-inch wheel confirmation rather than assuming interchangeability with other QX80 trims. It is the right starting point when the vehicle already carries the factory-style larger wheel setup and the goal is to maintain that overall fitment profile.
A 275/60R20 tire also uses a 275-millimeter nominal section width and radial construction, but its 60-series profile is paired with a 20-inch rim. On the 2020 Infiniti Trucks QX80, this size is tied to the sub-model using the 20-inch wheel package rather than the larger 22-inch setup. That makes it a trim-specific fitment rather than a universal QX80 size. It is the appropriate choice when the vehicle retains its 20-inch wheels and the goal is to match the existing wheel diameter and overall tire format already on the SUV.
Tire fitment on the 2020 Infiniti Trucks QX80 varies by sub-model, so trim identification matters before selecting a replacement. The main distinction is wheel diameter, with one trim using 20-inch wheels and the others using 22-inch wheels.

2020 Infiniti Trucks QX80 Limited
The 2020 Infiniti Trucks QX80 Limited uses the 275/50R22 radial fitment, tying it to the larger 22-inch wheel package. That makes wheel confirmation especially important before replacement, particularly if the SUV has changed hands or has had wheels swapped at some point.
The 2020 Infiniti Trucks QX80 Luxe uses the 275/60R20 radial size rather than the 22-inch fitment found on other covered trims. Tire selection here starts with retaining the correct 20-inch wheel diameter and matching the existing fitment rather than choosing by appearance alone.
The 2020 Infiniti Trucks QX80 Luxe Edition 30 uses the 275/50R22 radial tire size. For replacement, the practical priority is confirming that the vehicle still carries its 22-inch wheels so the new tire matches the trim-specific setup already in place.
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 2020 Infiniti Trucks QX80 usually center on trim-specific tire size, 20-inch versus 22-inch wheel fitment, and what to inspect before replacing or driving on a new set of SUV tires.
Tire Size & Fitment
What tire size fits a 2020 Infiniti Trucks QX80?
The 2020 Infiniti Trucks QX80 uses either 275/60R20 or 275/50R22, depending on the sub-model. The Luxe uses 275/60R20, while the Limited and Luxe Edition 30 use 275/50R22. Both are radial metric tire sizes, but they are tied to different wheel diameters and should be treated as distinct fitments.
The practical next step is to confirm the exact trim and check the wheel diameter currently on the vehicle. A QX80 that has had wheel changes over time may no longer match its original trim package, so the safest approach is to verify both the sub-model and the actual wheel size before choosing replacement tires.
What size rim does a 2020 Infiniti Trucks QX80 use?
A 2020 Infiniti Trucks QX80 uses either a 20-inch or 22-inch rim, depending on the sub-model. The 275/60R20 fitment is built for a 20-inch wheel, and the 275/50R22 fitment is built for a 22-inch wheel. Those two tire sizes are not simply alternate labels for the same wheel diameter.
Checking the rim diameter matters before anything else because the tire must match the wheel it is mounted on. Looking at the sidewall size code and physically confirming the wheel package is especially helpful on used vehicles, where trim badges, prior tire replacements, or aftermarket wheel changes can create confusion.
Why does the 2020 Infiniti Trucks QX80 have more than one tire size?
The 2020 Infiniti Trucks QX80 has more than one tire size because different sub-models use different wheel packages. The Luxe uses 275/60R20 on a 20-inch rim, while the Limited and Luxe Edition 30 use 275/50R22 on a 22-inch rim. The difference is trim-related rather than a matter of bias-ply versus radial construction, since both sizes are radial.
That means the right tire is determined by the exact vehicle configuration, not just the model name. Trim identification should come first, and wheel diameter should be confirmed second. Once those are verified, replacement shopping becomes much more straightforward because the buyer can focus on the one size that belongs on that particular QX80.
Choosing the Right Tire
What should I consider when choosing a 2020 Infiniti Trucks QX80 tire?
Start with the correct trim-specific size: 275/60R20 for the Luxe or 275/50R22 for the Limited and Luxe Edition 30. Because the 2020 Infiniti Trucks QX80 uses two different wheel diameters, correct fitment matters more than general tire shopping preferences. Choosing by model name alone can lead to the wrong size.
After size is confirmed, compare the tire's intended role with how the SUV is actually used. A QX80 that spends its time on highway trips, city driving, or occasional long-distance travel still needs the correct size first, then a tire that matches the vehicle's current wheel setup, condition, and overall replacement goals.
How do I choose between the available 275/50R22 and 275/60R20 tires for a 2020 Infiniti Trucks QX80?
The choice between 275/50R22 and 275/60R20 is not a styling preference on the 2020 Infiniti Trucks QX80; it is a fitment decision tied to sub-model and wheel diameter. Limited and Luxe Edition 30 models use 275/50R22, while the Luxe uses 275/60R20. Each size belongs to a different rim diameter.
The best way to narrow the decision is to verify what is currently on the vehicle. Check the sidewall marking on the existing tire and compare it with the actual wheel diameter. That simple step prevents ordering a 20-inch tire for a 22-inch wheel package, or the reverse, on a QX80 with a different trim setup.
Should I match the current tire size already on my 2020 Infiniti Trucks QX80?
Matching the current tire size is usually the right starting point, but it should still be confirmed against the QX80's trim and wheel diameter. A 2020 Infiniti Trucks QX80 should be running either 275/60R20 or 275/50R22, depending on the sub-model. Using the existing tire as a reference works best when the wheel package is known to be correct.
Used vehicles can complicate things because wheels and tires may have been changed by a previous owner. Compare the current sidewall size, the actual wheel diameter, and the vehicle's trim before replacing anything. That extra check helps keep the new tire aligned with the QX80's intended fitment instead of repeating an earlier mismatch.
Restoration & Appearance
Does correct tire fitment matter for a 2020 Infiniti Trucks QX80 restoration or preservation-minded build?
Yes, correct tire fitment still matters on a 2020 Infiniti Trucks QX80, especially when the goal is to preserve the vehicle's original trim-specific appearance and stance. The Luxe uses 275/60R20, while the Limited and Luxe Edition 30 use 275/50R22. Those sizes are tied to different wheel diameters and give the SUV a different visual presentation.
For a preservation-minded approach, keeping the proper size with the proper wheel package helps maintain the character of the specific trim rather than blending features from another version. If appearance accuracy matters, confirm the vehicle's exact trim and current wheel setup before replacing tires so the finished look remains consistent.
How does tire size affect the appearance of a 2020 Infiniti Trucks QX80?
Tire size affects the appearance of a 2020 Infiniti Trucks QX80 because the two fitments are built around different wheel diameters. The 275/50R22 setup delivers a larger-wheel presentation, while the 275/60R20 setup pairs with a 20-inch wheel package. Even though the overall tire dimensions are close, the wheel-and-sidewall balance changes the SUV's visual character.
That matters for owners who want the vehicle to retain the look associated with its original trim. A Limited or Luxe Edition 30 will not present the same way on a 20-inch package, and a Luxe will not match its original setup on 22s unless the wheel conversion has been intentionally planned and verified for fitment.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2020 Infiniti Trucks QX80?
Yes, modifications can affect tire fitment on a 2020 Infiniti Trucks QX80 even when the tire size itself is correct for the original trim. Aftermarket wheels, changes in wheel width or offset, suspension lowering or lifting, and body alterations can all change clearance around the tire. That applies whether the vehicle uses 275/60R20 or 275/50R22.
A modified QX80 should be checked for steering clearance, fender clearance, and full suspension travel before new tires are put into regular use. The safest habit is to confirm the actual wheel setup on the vehicle instead of assuming it still matches factory-style trim fitment, especially on a used SUV with unknown changes.
What should I inspect before driving a 2020 Infiniti Trucks QX80 on new tires?
Before driving a 2020 Infiniti Trucks QX80 on new tires, inspect the wheel size, verify that all four tires match the intended fitment, and check inflation pressure carefully. It is also wise to look over the wheels for damage and confirm that the tires have adequate clearance at full steering lock and under normal ride height.
A general pre-road inspection should also include suspension condition, alignment-related wear signs, and any evidence of rubbing from the previous set. On a large luxury SUV like the QX80, those checks help the new tires wear more evenly and reduce the chance of discovering a clearance or setup issue after the vehicle is back in service.
How often should tires on a 2020 Infiniti Trucks QX80 be inspected?
Tires on a 2020 Infiniti Trucks QX80 should be inspected regularly, not just when tread looks low. Pressure, tread wear pattern, sidewall condition, cuts, bulges, and signs of air loss all deserve routine attention. That is especially important on a heavy full-size SUV, where unnoticed wear or underinflation can affect ride quality and overall tire life.
A smart routine is to look them over before longer drives and any time ride feel changes. Uneven wear can point to alignment, suspension, or inflation problems rather than the tire itself. On a QX80 with either 20-inch or 22-inch wheels, catching those issues early helps protect both the tire investment and everyday road manners.
