The 2014 Infiniti Trucks QX80 sits in the modern full-size luxury SUV category, blending three-row utility with the substantial stance and road presence buyers expect from a premium body-on-frame vehicle. On a vehicle like this, tire choice affects not just appearance, but also ride height, wheel compatibility, and overall driving character. The 2014 Infiniti Trucks QX80 uses radial tires in two primary sizes, 275/50R22 and 275/60R20, tied to different wheel diameters. That makes wheel confirmation the first step, followed by choosing the right size for the vehicle’s current setup. Owners should also check for aftermarket wheel or suspension changes before selecting replacement tires.
Which Tire Size Is Right for The 2014 Infiniti Trucks QX80
The 2014 Infiniti Trucks QX80 uses two primary tire sizes, and the first thing to confirm is whether the vehicle has 20-inch or 22-inch wheels. Both sizes are radial metric fitments used on the QX80 Base, so the real decision starts with wheel diameter, then moves to matching the tire size to the vehicle’s current wheel setup and intended use.
The size 275/50R22 identifies a metric radial tire with a 275 millimeter nominal section width, a 50-series aspect ratio, and fitment for a 22-inch rim. On the 2014 Infiniti Trucks QX80, this size supports the larger wheel setup and keeps the fitment in a modern radial format familiar to current SUV owners. Its lower profile relative to the 20-inch option gives this size a more wheel-forward appearance. Choosing it starts with confirming that the QX80 is actually equipped with 22-inch wheels and that no wheel or suspension changes have altered clearance requirements.
The size 275/60R20 is a metric radial format that uses a 275 millimeter nominal section width, a 60-series aspect ratio, and a 20-inch rim. For the 2014 Infiniti Trucks QX80, this is the alternate primary fitment tied to the 20-inch wheel setup rather than the 22-inch package. It shares the same basic tire width as the 22-inch option while using a different wheel diameter and profile relationship. This size should be selected only after confirming the actual wheel diameter on the vehicle, especially if the QX80 has seen wheel swaps or other modifications.
Sub-model fitment is straightforward here because the covered QX80 Base can use either of the two primary tire sizes. What matters most is confirming whether the vehicle is on 20-inch or 22-inch wheels before choosing a replacement tire.

Frequently Asked Questions
Common QX80 tire questions usually come down to identifying the correct 20-inch or 22-inch fitment, understanding what the metric size means, and checking wheel, clearance, and maintenance details before regular road use.
Tire Size & Fitment
What tire size fits a 2014 Infiniti Trucks QX80?
The 2014 Infiniti Trucks QX80 uses two primary tire sizes: 275/50R22 and 275/60R20. Both are radial metric fitments, and both apply to the QX80 Base depending on which wheel package is on the vehicle.
The key is not choosing between two interchangeable sizes at random, but confirming whether the SUV has 22-inch or 20-inch wheels. Checking the current tire sidewall and the wheel itself is the safest starting point, especially on a used QX80 that may have had wheels changed since new.
What size rim does a 2014 Infiniti Trucks QX80 use?
A 2014 Infiniti Trucks QX80 uses either a 22-inch rim with 275/50R22 tires or a 20-inch rim with 275/60R20 tires. Those two tire sizes correspond to two different wheel diameters used on this model.
Rim diameter should be verified before ordering replacement tires because a 20-inch tire cannot be mounted on a 22-inch wheel, and vice versa. If the vehicle has aftermarket wheels, inspect the actual wheel markings rather than relying only on model assumptions or appearance.
Why does the 2014 Infiniti Trucks QX80 have more than one tire size?
The 2014 Infiniti Trucks QX80 has more than one tire size because it was fitted with different wheel diameters. The two primary sizes, 275/50R22 and 275/60R20, reflect 22-inch and 20-inch wheel setups rather than two sizes used interchangeably on the same rim.
That means the first fitment step is always wheel confirmation. Even though both sizes have a similar overall diameter range, they are built around different rims, so selecting the correct replacement depends on the wheel actually installed on the vehicle today.
Choosing the Right Tire
What should I consider when choosing a tire for a 2014 Infiniti Trucks QX80?
Start by confirming the correct primary size for the wheel on the vehicle: 275/50R22 for a 22-inch rim or 275/60R20 for a 20-inch rim. Both fitments are radial, so the main decision is matching the tire to the existing wheel diameter and overall vehicle setup.
After size, consider how the QX80 is used, whether it remains stock, and whether wheel changes have been made. It is also worth checking tire age, load suitability, and physical clearance around suspension and body components before committing to a replacement set.
How do I choose between the available 2014 Infiniti Trucks QX80 tire sizes?
The choice between 275/50R22 and 275/60R20 is determined by the wheel diameter already on the 2014 Infiniti Trucks QX80. These are not alternate sizes for the same rim, so the correct size depends on whether the vehicle has 22-inch or 20-inch wheels.
A quick visual check is not always enough, especially if the SUV has changed hands or received aftermarket wheels. Reading the existing tire sidewall and confirming the wheel size directly helps avoid ordering the wrong fitment and keeps the replacement process much more straightforward.
What rim-fitment details matter when choosing 2014 Infiniti Trucks QX80 tires?
Rim diameter is the most important rim-fitment detail on a 2014 Infiniti Trucks QX80 because the vehicle uses either a 20-inch or 22-inch tire size. The tire must match the wheel diameter exactly, so 275/60R20 belongs on a 20-inch rim and 275/50R22 belongs on a 22-inch rim.
Wheel width and overall wheel setup also matter, particularly if the QX80 has aftermarket rims. Along with diameter, check that the wheel and tire combination maintains proper clearance at the fenders, suspension, and steering components before putting the vehicle back into regular use.
Restoration & Appearance
Does correct tire fitment matter for a 2014 Infiniti Trucks QX80 restoration or preservation project?
Yes, correct tire fitment still matters on a 2014 Infiniti Trucks QX80, even though it is a newer collector-era luxury SUV rather than an earlier classic. The correct fitment starts with using the proper size for the wheel diameter on the vehicle: 275/50R22 or 275/60R20.
Keeping the proper size relationship helps preserve the QX80’s intended stance and avoids mismatches between tire and wheel. On a preservation-minded vehicle, it is smart to verify whether the wheels are original to the SUV or part of a later appearance change before choosing replacement tires.
How does tire size affect the appearance of a 2014 Infiniti Trucks QX80?
Tire size affects the appearance of a 2014 Infiniti Trucks QX80 because the two primary fitments are built around different wheel diameters. A 275/50R22 pairs with a 22-inch wheel, while a 275/60R20 pairs with a 20-inch wheel, so each setup presents the vehicle a little differently.
Appearance alone should not drive the decision unless the wheel setup is already being changed intentionally. For a clean, proper-looking result, the better approach is to match the replacement tire to the wheels currently on the QX80 and verify that the overall setup still clears the vehicle correctly.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2014 Infiniti Trucks QX80?
Yes, modifications can affect tire fitment on a 2014 Infiniti Trucks QX80. Wheel swaps, suspension changes, ride-height adjustments, and body alterations can all change the space available around the tires, even when the vehicle still appears to use one of the original size formats.
A QX80 with aftermarket wheels should be checked for actual rim diameter, width, and clearance before replacement tires are chosen. Steering travel, inner-fender space, and suspension movement are all worth inspecting so the selected tire matches the vehicle as it sits now, not just how it left the factory.
What should I inspect before driving a 2014 Infiniti Trucks QX80 on new tires?
Before driving a 2014 Infiniti Trucks QX80 on new tires, inspect the wheel size, confirm the tire size matches that wheel, and make sure the tires are inflated properly. It is also smart to look over the wheels, valve stems, and lug hardware during installation.
Once mounted, check for rubbing at full steering lock and inspect clearances with the suspension loaded normally. A short test drive followed by a second visual inspection can help catch any contact issues, vibration, or air loss before the vehicle returns to everyday highway use.
How often should tires on a 2014 Infiniti Trucks QX80 be inspected?
Tires on a 2014 Infiniti Trucks QX80 should be inspected regularly, not just when tread looks worn. Frequent checks for pressure loss, uneven wear, cuts, bulges, and cracking are especially important on a heavy luxury SUV that may spend time parked between longer trips.
A quick visual check every month and before highway travel is a sensible routine. It also helps to inspect tires after impacts with potholes or curbs, since wheel damage or sidewall injury may not be obvious immediately but can affect ride quality and safe continued use.
