The 2020 Infiniti Trucks QX50 sits in the modern luxury crossover space, blending upscale road manners with the everyday practicality that made compact premium SUVs so popular by the end of the 2010s. For this exact model year, tire selection centers on two radial sizes, with fitment changing by sub-model and wheel package rather than one universal setup. Some versions use 235/55R19, while others step up to 255/45R20, so the first job is confirming the trim and wheel diameter already on the vehicle. From there, the choice becomes more specific: comparing available tire series, sidewall treatments, and overall road-use priorities without overlooking wheel compatibility.
Which Tire Size Is Right for The 2020 Infiniti Trucks QX50
The 2020 Infiniti Trucks QX50 uses two primary tire sizes, and the correct one depends on the exact sub-model and wheel diameter. Both fitments are radial, but one is built around a 19-inch rim and the other around a 20-inch rim, so confirming the trim level and checking the wheels already on the vehicle should come before comparing tire options.
Fit(s): Autograph, Essential Edition 30, and Sensory
Construction: Radial|Rim: 20 in
255/45R20 is a metric radial size in which 255 is the nominal section width in millimeters, 45 is the aspect ratio, R identifies radial construction, and 20 is the rim diameter in inches. On the 2020 Infiniti Trucks QX50, this size belongs to specific sub-models equipped with 20-inch wheels rather than the full model line. Available choices include BFGoodrich, Nitto, and Pro-Trac, with blackwall, raised white letter, and redline sidewall treatments represented across several tire series. This size is the one to evaluate when the vehicle already wears 20-inch wheels and the buyer wants to compare appearance and product character within that setup.
235/55R19 is a metric radial size where 235 gives the nominal section width in millimeters, 55 is the aspect ratio, R marks radial construction, and 19 identifies the rim diameter in inches. For the 2020 Infiniti Trucks QX50, this size applies to sub-models equipped with 19-inch wheels, making wheel confirmation just as important as trim identification. Its overall profile differs from the 20-inch fitment even though both sizes are close in overall diameter. This is the correct starting point for QX50 versions that remain on 19-inch wheels and are being matched to their original wheel diameter rather than converted.
Tire fitment changes across the 2020 Infiniti Trucks QX50 range, so identifying the exact sub-model matters before choosing a size. Some trims use 19-inch wheels with 235/55R19 tires, while others use 20-inch wheels with 255/45R20 tires.

2020 Infiniti Trucks QX50 Autograph
The 2020 Infiniti Trucks QX50 Autograph uses the 255/45R20 radial fitment. Tire selection for this sub-model starts with confirming the 20-inch wheel setup, then comparing the available product lines and sidewall styles that suit the vehicle's intended road use and appearance.
The 2020 Infiniti Trucks QX50 Essential uses the 235/55R19 radial size. That makes the tire decision more straightforward as long as the vehicle still carries its 19-inch wheels and has not been changed to a different wheel package.
The 2020 Infiniti Trucks QX50 Essential Edition 30 uses the 255/45R20 radial fitment. Buyers with this sub-model should verify the existing 20-inch wheels first, then focus on the tire series and sidewall presentation that best match the crossover's use and overall look.
The 2020 Infiniti Trucks QX50 Luxe uses the 235/55R19 radial size. For this sub-model, the key step is staying with the 19-inch wheel fitment unless the vehicle has been modified, then selecting a tire that matches everyday driving needs and wheel compatibility.
The 2020 Infiniti Trucks QX50 Pure uses the 235/55R19 radial size. That keeps fitment centered on the 19-inch wheel package, so selection comes down to using the correct size and confirming the wheels are still the same diameter and width they were built around.
The 2020 Infiniti Trucks QX50 Sensory uses the 255/45R20 radial fitment. This sub-model should be matched to the 20-inch wheel setup already on the vehicle, with attention given to the available tire series and sidewall treatments within that size.
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.

Owners of a 2020 Infiniti Trucks QX50 usually need to sort out trim-specific tire size, 19-inch versus 20-inch wheel fitment, and the differences between the available radial tire choices. The questions below focus on exact size selection, product comparison, and practical checks before road use.
Tire Size & Fitment
What tire size fits a 2020 Infiniti Trucks QX50?
The 2020 Infiniti Trucks QX50 uses either 235/55R19 or 255/45R20, depending on the sub-model. Pure, Luxe, and Essential use 235/55R19, while Autograph, Essential Edition 30, and Sensory use 255/45R20.
That means there is not one universal tire size for every 2020 QX50. The safest starting point is to confirm the exact trim and verify whether the vehicle is on 19-inch or 20-inch wheels before comparing tires, especially if the crossover has had wheel changes since new.
What size rim does a 2020 Infiniti Trucks QX50 use?
A 2020 Infiniti Trucks QX50 uses either a 19-inch or 20-inch rim, depending on sub-model and tire size. The 235/55R19 fitment belongs to a 19-inch rim, while the 255/45R20 fitment belongs to a 20-inch rim.
Rim diameter should be confirmed before anything else because the two primary tire sizes are tied to different wheels. Checking the marking on the current tire and confirming the actual wheel setup on the vehicle helps avoid choosing a tire that matches the trim name but not the wheels currently installed.
Do all 2020 Infiniti Trucks QX50 sub-models use the same tire size?
No, the 2020 Infiniti Trucks QX50 does not use one tire size across every sub-model. Some trims use 235/55R19, while others use 255/45R20, so fitment changes with the vehicle's configuration.
That matters because the two sizes also use different rim diameters. A buyer looking at QX50 tires should identify the exact sub-model first, then confirm the actual wheels on the vehicle, since a changed wheel package can matter just as much as the original trim designation.
Choosing the Right Tire
What should I consider when choosing a 255/45R20 tire for a 2020 Infiniti Trucks QX50?
Start with the correct fitment: 255/45R20 belongs on the 2020 Infiniti Trucks QX50 sub-models built around 20-inch wheels. Within that size, available choices vary by brand, tire series, sidewall style, and in some cases rim-width specification and load-related details.
The practical decision is matching the tire to how the QX50 is used and how it should look. A blackwall presentation keeps things understated, while raised white letter or redline sidewalls create a more customized appearance, and wheel width should still be checked before settling on a specific product.
What sidewall styles are available for 2020 Infiniti Trucks QX50 tires?
The available 255/45R20 options for the 2020 Infiniti Trucks QX50 include blackwall, raised white letter, and redline sidewall treatments. Those choices appear across the product range for the 20-inch fitment rather than as one uniform appearance across every tire.
Sidewall styling changes the look of the vehicle more than the fitment itself, so it should be chosen after the correct size and wheel diameter are confirmed. A buyer trying to preserve a clean late-model appearance may lean toward blackwall, while a more customized look may point toward raised white letter or redline.
What brands offer tires for the 2020 Infiniti Trucks QX50?
For the 255/45R20 fitment on the 2020 Infiniti Trucks QX50, available brands include BFGoodrich, Nitto, and Pro-Trac. Those options also span several tire series, so brand choice is only one part of the decision.
Comparing tires by brand alone can miss differences in sidewall presentation, rim-width compatibility, and overall product character. Once the correct QX50 size is confirmed, it makes more sense to compare each tire as a complete package rather than assuming every product in the same size serves the same purpose.
Restoration & Appearance
Which tire should I choose for a period-style 2020 Infiniti Trucks QX50?
A period-style approach on a 2020 Infiniti Trucks QX50 starts with keeping the correct trim-specific size and wheel diameter, either 235/55R19 or 255/45R20. Since this is a modern luxury crossover, the most restrained appearance usually comes from staying with the proper radial fitment and a clean sidewall treatment.
Appearance still depends on the wheel package already on the vehicle. Buyers using the 255/45R20 fitment can compare blackwall, raised white letter, and redline presentations, while anyone trying to keep the vehicle visually close to stock should confirm the existing wheels before choosing a more customized sidewall style.
Which sidewall style suits a period-style 2020 Infiniti Trucks QX50?
For a period-style 2020 Infiniti Trucks QX50, blackwall is the most understated sidewall treatment among the available 255/45R20 options. Raised white letter and redline sidewalls are also available, but they push the vehicle toward a more personalized look.
The right choice depends on whether the goal is a clean original-looking presentation or a more expressive visual statement. Sidewall treatment does not override fitment, so the exact tire size and wheel diameter should be confirmed first, then the appearance can be matched to the character the vehicle owner wants.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2020 Infiniti Trucks QX50?
Yes, modifications can affect tire fitment on a 2020 Infiniti Trucks QX50 even when the tire size sounds close to the original setup. Wheel changes, altered offsets, suspension lowering, and other aftermarket changes can all influence how a 235/55R19 or 255/45R20 tire sits and clears.
A QX50 that no longer wears its original wheel package should be checked carefully before replacement tires are chosen. Looking at wheel diameter, wheel width, clearance at full steering lock, and visible fender or suspension changes helps prevent ordering a tire based only on trim level when the actual setup has changed.
What should I inspect before driving a 2020 Infiniti Trucks QX50 on new tires?
Before driving a 2020 Infiniti Trucks QX50 on new tires, inspect the wheel condition, confirm the tires match the correct size for the trim, and check inflation pressure. It also makes sense to look for obvious rubbing points, damaged valve stems, and any signs that the suspension or alignment needs attention.
That first inspection matters because tire size alone does not tell the whole story on a vehicle with multiple wheel packages. A short, careful road test can help confirm there is no interference, vibration, or unusual steering feel, especially if the crossover has recently had wheel service or suspension work.
What should I check before a longer drive in a 2020 Infiniti Trucks QX50?
Before a longer drive in a 2020 Infiniti Trucks QX50, check inflation pressure, tread condition, and the sidewalls for cuts, bulges, or cracking. The vehicle should also be on the correct trim-specific tire size, with 235/55R19 and 255/45R20 not treated as interchangeable without verifying the wheel setup.
Longer trips put more emphasis on consistency and condition than short local use. It is worth confirming there is no slow air loss, that the wheels are properly matched to the tires, and that the vehicle shows no signs of rubbing or uneven wear before putting sustained highway miles on it.
