The 2017 Infiniti Trucks QX80 sits in the full-size luxury SUV category, blending a large body-on-frame platform with upscale trim and highway-focused comfort. Buyers often come to this vehicle expecting premium ride quality, substantial road presence, and a tire package that matches both its size and appearance. For the 2017 Infiniti Trucks QX80, tire fitment centers on two radial sizes, 275/50R22 and 275/60R20, depending on the wheel setup and sub-model. That makes the key decision less about vintage-style construction and more about confirming the correct rim diameter, understanding how each metric size reads, and matching the tire to the vehicle's current wheels and intended use.
Which Tire Size Is Right for The 2017 Infiniti Trucks QX80
Two tire sizes apply to the 2017 Infiniti Trucks QX80, and the first thing to confirm is wheel diameter. The vehicle uses radial tires in either 275/50R22 or 275/60R20, with fitment varying by sub-model and wheel setup. Before choosing a tire, make sure the QX80 is riding on 20-inch or 22-inch wheels, then match the size to that exact configuration.
The size 275/50R22 identifies a metric radial tire that is 275 millimeters wide, uses a 50-series aspect ratio, and fits a 22-inch rim. On the 2017 Infiniti Trucks QX80, this size supports the larger-wheel setup and gives the vehicle a more contemporary, lower-profile presentation than the 20-inch alternative. Its radial construction matches the QX80's modern luxury SUV character and road-use expectations. This is the size to evaluate when the vehicle has 22-inch wheels and you want to preserve the intended proportions, handling balance, and visual stance tied to that wheel package.
The size 275/60R20 is a metric radial with a 275-millimeter section width, a 60-series profile, and fitment for a 20-inch rim. On the 2017 Infiniti Trucks QX80, it serves the 20-inch wheel configuration while maintaining a very similar overall tire diameter to the 22-inch setup. That keeps this size squarely in the correct fitment conversation for the vehicle rather than functioning as a styling-driven alternative. Choose this size only after confirming the QX80 actually has 20-inch wheels, especially if the vehicle has seen wheel changes or trim-level equipment changes over time.
Sub-model fitment matters on the 2017 Infiniti Trucks QX80 because tire size is tied to wheel package and trim. The Limited uses one radial size, while the Base can be found with either of the two supported sizes, so the exact wheel diameter should be checked before ordering tires.

2017 Infiniti Trucks QX80 Base
The 2017 Infiniti Trucks QX80 Base can use either of the two supported radial sizes, depending on whether it is equipped with 20-inch or 22-inch wheels. That means tire selection starts with confirming the current wheel diameter rather than assuming one size applies to every Base model.
The 2017 Infiniti Trucks QX80 Limited uses the 275/50R22 radial size. For this sub-model, the tire decision is more straightforward, but it still makes sense to confirm that the vehicle remains on its 22-inch wheel setup if wheels have ever been changed.
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 tire sizes used on the 2017 Infiniti Trucks QX80, how sub-model and wheel diameter affect fitment, and what to inspect before choosing or driving on replacement tires.
Tire Size & Fitment
What tire size fits a 2017 Infiniti Trucks QX80?
The 2017 Infiniti Trucks QX80 uses two radial tire sizes: 275/50R22 and 275/60R20. The correct one depends on the wheel package and sub-model, with the Limited using 275/50R22 and the Base appearing with either supported size.
The most important step is confirming the actual wheel diameter on the vehicle before replacing tires. A QX80 on 22-inch wheels needs 275/50R22, while a QX80 on 20-inch wheels needs 275/60R20. That matters even more if the SUV has had wheel changes, dealer-installed accessories, or previous owner modifications.
What size rim does a 2017 Infiniti Trucks QX80 use?
The 2017 Infiniti Trucks QX80 uses either a 22-inch rim or a 20-inch rim, depending on configuration. The 275/50R22 tire fits a 22-inch wheel, and the 275/60R20 tire fits a 20-inch wheel.
Rim diameter is the first fitment check because the tire bead must match the wheel exactly. Even though the two supported sizes have very similar overall diameter, they are not interchangeable across 20-inch and 22-inch wheels. Reading the current tire sidewall and confirming the wheel size directly on the vehicle is the safest starting point.
Do all 2017 Infiniti Trucks QX80 sub-models use the same tire size?
No. The 2017 Infiniti Trucks QX80 Limited uses 275/50R22, while the Base can use either 275/50R22 or 275/60R20 depending on its wheel setup. Tire choice is therefore not identical across every QX80 sub-model.
That difference means trim name alone does not always settle the fitment question on a Base model. It is still necessary to confirm whether the SUV has 20-inch or 22-inch wheels before selecting tires. Matching the replacement size to the current wheel package helps avoid ordering a tire that fits the vehicle family but not the specific QX80 in front of you.
Choosing the Right Tire
What should I consider when choosing a tire for a 2017 Infiniti Trucks QX80?
Start with the correct size for the vehicle's wheel package: 275/50R22 for 22-inch wheels or 275/60R20 for 20-inch wheels. Both are radial metric sizes, so the main decision is not construction type but matching the replacement tire to the QX80's actual wheel diameter and intended driving use.
After size is confirmed, compare the tire's overall suitability for a large luxury SUV. Wheel compatibility, load capability, tread design, and the kind of road use the QX80 sees all matter. A vehicle used mainly for highway travel may call for a different tire character than one that sees heavier cargo or frequent long-distance family trips.
How do I choose between the available 2017 Infiniti Trucks QX80 tire sizes?
You do not choose between the two sizes as styling alternatives unless the wheel package changes with them. The 2017 Infiniti Trucks QX80 uses 275/50R22 with 22-inch wheels and 275/60R20 with 20-inch wheels, so the correct size is determined by the rim already on the vehicle.
The practical question is whether the SUV still has its intended wheel setup. A Base model may be equipped with either size, so visual inspection and sidewall confirmation are important. Once the correct size is established, compare replacement tires within that size instead of trying to move between 20-inch and 22-inch fitments without a wheel change.
What rim-fitment details matter when choosing 2017 Infiniti Trucks QX80 tires?
The key rim-fitment detail is diameter. A 275/50R22 tire belongs on a 22-inch wheel, while a 275/60R20 tire belongs on a 20-inch wheel. The QX80's two supported sizes are close in overall diameter, but they are built for different wheel diameters and cannot be treated as interchangeable on the same rim.
It also helps to confirm that the wheels on the vehicle are the correct type for the tire being considered and that nothing has changed since the SUV left its original configuration. If aftermarket wheels are installed, checking width, offset, and clearance can prevent rubbing issues or mismatched tire-to-wheel proportions.
Restoration & Appearance
Does correct tire fitment matter for a 2017 Infiniti Trucks QX80 restoration or preservation project?
Yes. Even though the 2017 Infiniti Trucks QX80 is a modern luxury SUV rather than a vintage restoration candidate, keeping the correct tire size tied to its wheel package still matters for preserving the vehicle's intended look and stance. The supported sizes are 275/50R22 and 275/60R20, depending on configuration.
A preservation-minded owner should avoid treating those two sizes as cosmetic substitutes. The wheel diameter determines the correct tire, and the tire helps shape the SUV's overall presentation. For a clean, original-style appearance, confirm whether the vehicle is meant to remain on 20-inch or 22-inch wheels before choosing replacement tires.
How does tire size affect the appearance of a 2017 Infiniti Trucks QX80?
Tire size has a visible effect on the 2017 Infiniti Trucks QX80 because the two supported fitments pair with different wheel diameters. The 275/50R22 size gives the SUV a larger-wheel, lower-profile appearance, while 275/60R20 carries more sidewall on a smaller rim.
Both sizes stay in the correct fitment range for the QX80, but they create a different visual balance. Appearance should still follow wheel configuration, not the other way around. If maintaining a consistent factory-style presentation matters, match the replacement tire to the wheel package already on the vehicle rather than mixing size and rim diameter.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2017 Infiniti Trucks QX80?
Yes. Wheel changes, suspension alterations, and body modifications can all affect tire fitment on a 2017 Infiniti Trucks QX80. That matters because the SUV already uses two different supported sizes, 275/50R22 and 275/60R20, depending on wheel diameter.
An owner should confirm more than just the sidewall size if the QX80 has been modified. Aftermarket wheels may change offset or width, and lowered or altered suspension can change clearance during turning or full compression. Checking the actual wheel setup and physical clearance around the tire helps avoid rubbing, contact, or unwanted fitment surprises.
What should I inspect before driving a 2017 Infiniti Trucks QX80 on new tires?
Before road use, inspect the new tires for correct size, proper seating on the wheel, and consistent inflation. On a 2017 Infiniti Trucks QX80, that starts with verifying that 275/50R22 tires are on 22-inch wheels or that 275/60R20 tires are on 20-inch wheels.
It is also smart to look over the rest of the vehicle's tire-related condition before a full drive. Check for rubbing at lock-to-lock steering, uneven wear from alignment issues, valve condition, and any signs of wheel damage. A short initial drive followed by another pressure and visual check can catch problems before they become larger road-use concerns.
How often should tires on a 2017 Infiniti Trucks QX80 be inspected?
Tires on a 2017 Infiniti Trucks QX80 should be inspected regularly, not just when replacement time arrives. A visual check for pressure loss, uneven wear, cuts, cracking, or bulges is worthwhile before longer trips and as part of normal routine ownership.
A large luxury SUV puts real demands on its tires, so condition matters as much as size. Periodic inspection also helps catch issues tied to alignment, suspension wear, or wheel damage that can affect ride quality and tread life. Paying attention to both tire condition and correct fitment supports safer, more predictable road use.
