The 2023 Infiniti Trucks QX50 sits in the modern luxury crossover space, where quiet road manners, upscale styling, and wheel-and-tire presentation all play a visible role in how the vehicle feels on the road. For this exact model, tire fitment centers on two radial sizes: 235/55R19 and 255/45R20, with the correct choice tied to the vehicle’s specific sub-model. That makes this less about vintage construction decisions and more about confirming wheel diameter first, then comparing available tire character, sidewall treatment, and overall appearance. Owners keeping a QX50 close to stock should match the original size format carefully and inspect wheel, suspension, and clearance conditions before any change.
Which Tire Size Is Right for The 2023 Infiniti Trucks QX50
The 2023 Infiniti Trucks QX50 uses two primary tire sizes, and the right one depends on the exact sub-model and wheel diameter. Both are modern radial fitments, but one is built around a 19-inch wheel and the other around a 20-inch wheel, so confirming the vehicle’s current wheel setup is the first step before comparing tire choices or appearance options.
255/45R20 is a modern metric radial size in which 255 identifies the nominal section width in millimeters, 45 is the aspect ratio, R indicates radial construction, and 20 is the wheel diameter in inches. On the 2023 Infiniti Trucks QX50, this size is used on specific upper-trim configurations built around a 20-inch wheel. Available choices in this size include BFGoodrich, Nitto, and Pro-Trac options, with Blackwall, raised white letter, and Redline sidewall treatments appearing in the mix. It is the size to evaluate when the QX50 has the 20-inch package and you want to compare both performance-oriented and appearance-driven tire options.
235/55R19 is a modern metric radial size where 235 refers to the nominal section width in millimeters, 55 indicates the aspect ratio, R denotes radial construction, and 19 is the wheel diameter in inches. On the 2023 Infiniti Trucks QX50, this size belongs to sub-models equipped with 19-inch wheels rather than the larger 20-inch setup. Tire selection in this fitment starts with matching the correct wheel diameter and maintaining the intended overall size relationship. It is the right size to pursue when the vehicle remains on its 19-inch wheel configuration and the goal is to stay aligned with that specific factory-style setup.
Tire fitment for the 2023 Infiniti Trucks QX50 varies by sub-model, so identifying the exact trim matters before choosing a tire. Some versions use 19-inch wheel fitment with 235/55R19 tires, while others use 20-inch wheel fitment with 255/45R20 tires.

Tire Size & Fitment
What tire size fits a 2023 Infiniti Trucks QX50?
The 2023 Infiniti Trucks QX50 uses either 235/55R19 or 255/45R20, depending on the sub-model. Luxe and Pure use 235/55R19, while Autograph, Sensory, and Sport use 255/45R20. Both are radial tire fitments, but they are tied to different wheel diameters.
That means the first check is not simply the model name, but the exact trim and the wheels currently on the vehicle. A QX50 that has had wheel changes may no longer match its original trim-based fitment, so confirming the actual wheel diameter before ordering replacement tires helps avoid choosing the wrong size.
What size rim does a 2023 Infiniti Trucks QX50 use?
The 2023 Infiniti Trucks QX50 uses either a 19-inch or 20-inch rim, depending on sub-model. The 235/55R19 fitment is built around a 19-inch wheel, while the 255/45R20 fitment is built around a 20-inch wheel.
Wheel diameter is the key fitment checkpoint on this vehicle because the two tire sizes are not interchangeable across different rim diameters. Checking the actual wheel on the vehicle matters most if the QX50 has aftermarket wheels, a second seasonal wheel set, or a previous owner who changed the original trim-based setup.
Do all 2023 Infiniti Trucks QX50 sub-models use the same tire size?
No, the 2023 Infiniti Trucks QX50 does not use one tire size across every sub-model. Autograph, Sensory, and Sport use 255/45R20, while Luxe and Pure use 235/55R19, so fitment changes with trim level.
That distinction matters because the difference is not just width or profile, but also wheel diameter. A buyer selecting tires by model name alone could end up in the wrong size category, so matching the tire to the trim and then confirming the actual wheels on the vehicle is the most practical way to narrow the fitment correctly.
Choosing the Right Tire
What should I consider when choosing a 255/45R20 tire for a 2023 Infiniti Trucks QX50?
Start by confirming that the QX50 actually uses the 255/45R20 fitment, which applies to the Autograph, Sensory, and Sport sub-models. From there, compare construction details within that size, including rim-width compatibility where stated, sidewall style, tire series, weight, and any load information shown for a given product.
The next decision is usually about how the vehicle is used and how you want it to look. Some owners will want a straightforward Blackwall presentation, while others may prefer raised white letters or a Redline treatment. Staying with the correct size and checking wheel condition, clearance, and overall setup keeps the comparison focused and useful.
What sidewall styles are available for 2023 Infiniti Trucks QX50 tires?
For the 255/45R20 fitment used on certain 2023 Infiniti Trucks QX50 sub-models, available sidewall styles include Blackwall, raised white letter, and Redline. Those choices appear across the BFGoodrich, Nitto, and Pro-Trac product selection in this size.
Sidewall style does not change the underlying tire size requirement, but it can change the overall presentation of the vehicle. A Blackwall keeps a more understated modern look, while raised white letters or a Redline give the QX50 a more customized visual character. Tire selection should still begin with the correct trim and wheel diameter before appearance details are compared.
What brands offer tires for the 2023 Infiniti Trucks QX50?
The 255/45R20 fitment for the 2023 Infiniti Trucks QX50 is available from BFGoodrich, Nitto, and Pro-Trac. Those options also span different tire series, including g-Force Comp 2 AS, g-Force Sport Comp 2, Nitto NT555 G2, and Street Pro III.
Brand alone should not be the only deciding factor. It helps to compare the exact tire series, sidewall treatment, and wheel-fit details within the correct size, especially if appearance matters as much as road use. Once the correct 20-inch fitment is confirmed, those differences become the most meaningful way to sort the available choices.
Restoration & Appearance
Which tire should I choose for a period-style 2023 Infiniti Trucks QX50?
A period-style question matters less on a 2023 Infiniti Trucks QX50 than it would on a vintage vehicle, but appearance still plays a role in tire choice. The starting point is keeping the correct trim-based size, then choosing among available 255/45R20 products if the vehicle uses the 20-inch fitment.
For a more restrained factory-like look, a Blackwall is the most natural direction. Owners wanting a more personalized presentation may lean toward raised white letter or Redline sidewalls in the same size. Matching the original wheel diameter and avoiding unnecessary size changes will usually preserve the cleanest overall look on a modern QX50.
How does tire construction affect the appearance of a restored 2023 Infiniti Trucks QX50?
On the 2023 Infiniti Trucks QX50, tire construction is straightforward because the primary fitments are radial. The visible appearance difference comes less from construction type and more from the exact size, tread family, and sidewall style chosen within the correct trim-based fitment.
That means a QX50 kept close to stock appearance benefits most from retaining the proper 19-inch or 20-inch size relationship and avoiding mismatched wheel-and-tire combinations. Sidewall treatment has a bigger visual effect here than any construction decision, so appearance-focused buyers should compare Blackwall, raised white letter, and Redline options carefully.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2023 Infiniti Trucks QX50?
Yes, modifications can affect tire fitment on a 2023 Infiniti Trucks QX50. Aftermarket wheels, suspension changes, altered ride height, or body modifications can change the clearance relationship around a 235/55R19 or 255/45R20 tire, even when the vehicle still appears to use the original trim-based size.
That is why the actual wheel diameter and overall setup should be checked before choosing replacements. A QX50 with non-original wheels may need closer attention to wheel width, offset, and space at the fender and suspension. Keeping those points in mind is especially important when moving between 19-inch and 20-inch wheel configurations.
What should I inspect before driving a 2023 Infiniti Trucks QX50 on new tires?
Before driving a 2023 Infiniti Trucks QX50 on new tires, inspect wheel condition, verify the tire size matches the vehicle’s trim and wheel diameter, and make sure inflation is set appropriately for the installation. It also helps to look over the suspension and steering components for obvious wear that could affect tire behavior.
A quick clearance check at full steering lock is worthwhile, especially if the vehicle has aftermarket wheels or prior modifications. After the first period of driving, recheck tire pressure and look for any signs of rubbing or uneven wear. Those simple steps help confirm that the new tires are working properly with the QX50’s actual setup.
How often should tires on a 2023 Infiniti Trucks QX50 be inspected?
Tires on a 2023 Infiniti Trucks QX50 should be inspected regularly rather than only at replacement time. Routine checks should include tread wear, air pressure, cuts, bulges, sidewall damage, and any signs of uneven wear that could point to alignment, suspension, or inflation issues.
A modern luxury crossover can hide tire problems until road noise, vibration, or handling changes become noticeable, so periodic visual inspection is worthwhile even when the vehicle seems to drive normally. Looking over the tires before longer trips and after impacts with potholes or curbs is an especially practical habit on 19-inch and 20-inch wheel setups.
