The 2024 Infiniti Trucks QX50 sits in the modern luxury crossover space, where ride quality, confident road manners, and a clean upscale look all matter just as much as outright utility. Tire selection on this QX50 depends first on trim, because the model uses either 235/55R19 or 255/45R20 radial tires. That means the real decision is not just size, but also whether the vehicle is on a 19-inch or 20-inch wheel and what kind of presentation you want from the available tires. Blackwall, redline, and raised white letter choices add another layer for owners who want the fitment to match the vehicle's style and use.
Which Tire Size Is Right for The 2024 Infiniti Trucks QX50
The 2024 Infiniti Trucks QX50 uses two primary tire sizes, and the right one depends on the exact sub-model and wheel diameter. Both fitments are radial, but one rides on a 19-inch rim and the other on a 20-inch rim, so confirming the trim and the actual wheel on the vehicle is the first step before comparing tire choices.
255/45R20 is a metric radial size where 255 is the section width in millimeters, 45 is the aspect ratio, R identifies radial construction, and 20 is the wheel diameter in inches. On the 2024 Infiniti Trucks QX50, this size is used on specific higher-wheel configurations, so it should be matched to the correct trim and 20-inch rim. Available choices include BFGoodrich, Nitto, and Pro-Trac, with sidewall treatments such as Blackwall, RWL, and Redline across several tire series. This size is the one to evaluate when the QX50 carries the larger factory wheel package and appearance matters alongside fitment.
235/55R19 is a metric radial size where 235 is the section width in millimeters, 55 is the aspect ratio, R indicates radial construction, and 19 is the wheel diameter in inches. On the 2024 Infiniti Trucks QX50, this fitment belongs to the 19-inch wheel setup, so the first priority is confirming that the vehicle has the correct rim diameter for this size. This format generally points to a taller-sidewall presentation than the 20-inch option, which can influence how owners think about ride character and appearance. Use this size when the QX50's trim and wheel package call for the 19-inch fitment.
Tire fitment on the 2024 Infiniti Trucks QX50 is trim-specific rather than uniform across the lineup. Checking the exact sub-model matters because the QX50 uses both 19-inch and 20-inch wheel-and-tire combinations, and the correct tire size follows that setup.

Tire Size & Fitment
What tire size fits a 2024 Infiniti Trucks QX50?
The 2024 Infiniti Trucks QX50 uses two tire sizes: 235/55R19 and 255/45R20. Both are radial fitments, and the correct size depends on the sub-model. Luxe and Pure use 235/55R19, while Autograph, Sensory, and Sport use 255/45R20.
The most important next step is confirming the exact trim and the actual wheel diameter on the vehicle. A QX50 that has had wheels changed since new may not still carry its original setup, so checking the tire sidewall and the wheel itself helps prevent choosing a size that does not match the current rim.
What size rim does a 2024 Infiniti Trucks QX50 use?
The 2024 Infiniti Trucks QX50 uses either a 19-inch or 20-inch rim, depending on sub-model. The 235/55R19 tire fits the 19-inch setup, and the 255/45R20 tire fits the 20-inch setup. Both fitments are radial and belong to different trim-level wheel packages.
Wheel diameter is the first fitment point to verify before comparing tires. Even if the overall tire height looks close between the two sizes, a 19-inch tire cannot be mounted on a 20-inch wheel, and a 20-inch tire cannot be mounted on a 19-inch wheel. That makes actual wheel measurement or sidewall confirmation essential.
Do all 2024 Infiniti Trucks QX50 sub-models use the same tire size?
No, the 2024 Infiniti Trucks QX50 does not use one tire size across every sub-model. Luxe and Pure use 235/55R19, while Autograph, Sensory, and Sport use 255/45R20. The difference follows the wheel-and-tire package assigned to each trim.
That variation means tire selection starts with identifying the exact sub-model or checking the wheel currently on the vehicle. It is especially important on a late-model luxury crossover like the QX50, where appearance packages and wheel upgrades can change what fits. Matching the tire to the installed rim is more important than assuming all trims share one size.
Choosing the Right Tire
What should I consider when choosing a 255/45R20 tire for a 2024 Infiniti Trucks QX50?
Start by confirming that the QX50 is one of the trims that uses 255/45R20 and that it still has a 20-inch wheel. In this size, available choices include BFGoodrich, Nitto, and Pro-Trac radial tires, with differences in tire series, sidewall style, and certain product details such as rim-width guidance or load information.
Once the size is confirmed, compare the tire's overall character with how the vehicle is used. Some owners may want a clean blackwall look, while others may prefer redline or raised white letter styling. It also helps to review wheel-width compatibility, especially if the QX50 has aftermarket wheels rather than the original factory-installed 20-inch setup.
What sidewall styles are available for 2024 Infiniti Trucks QX50 tires?
For the 255/45R20 fitment used on certain 2024 Infiniti Trucks QX50 trims, available sidewall styles include Blackwall, RWL, and Redline. Blackwall keeps the appearance understated, while RWL adds raised white lettering and Redline gives the tire a more custom visual accent.
Sidewall style does not change the required tire size, but it can significantly change how the QX50 looks once mounted. The right choice depends on whether the goal is a subtle luxury presentation or a more expressive appearance. It is still important to keep the fitment correct first, then use sidewall treatment as the finishing decision.
What brands offer tires for the 2024 Infiniti Trucks QX50?
In the 255/45R20 fitment, the 2024 Infiniti Trucks QX50 has tire options from BFGoodrich, Nitto, and Pro-Trac. Those products appear across several tire series, including g-Force Comp 2 AS, g-Force Sport Comp 2, Nitto NT555 G2, and Street Pro III.
Brand choice should be weighed alongside size, wheel compatibility, sidewall appearance, and the overall character of the tire series. A useful comparison starts with making sure the tire matches the QX50's installed 20-inch setup, then looking at whether the product has the presentation and specifications that fit the vehicle's intended use.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2024 Infiniti Trucks QX50?
Yes, modifications can change tire fitment on a 2024 Infiniti Trucks QX50 even when the original tire size is known. Aftermarket wheels, suspension changes, lowering, or altered alignment settings can affect clearance, wheel-width suitability, and how the tire sits within the fender opening.
That makes it important to inspect the actual setup before replacing tires, especially on a used vehicle. Checking wheel diameter, wheel width, and visible clearance at full steering lock helps avoid selecting a tire solely by trim name. Any QX50 with changed wheels should be measured rather than assumed to match its original factory configuration.
What should I inspect before driving a 2024 Infiniti Trucks QX50 on new tires?
Before driving a 2024 Infiniti Trucks QX50 on new tires, inspect tire pressure, wheel fastener torque, valve stems, and visible clearance around the suspension and fenders. It is also smart to confirm that all four tires are the correct size for the trim and that the wheel diameter matches the installed tires.
A short initial road check can help confirm that the vehicle tracks normally and that there is no rubbing during turns or over bumps. After the first miles, rechecking pressure and giving the tires a quick visual inspection is worthwhile. That simple follow-up helps catch mounting, clearance, or air-retention issues early.
How often should tires on a 2024 Infiniti Trucks QX50 be inspected?
Tires on a 2024 Infiniti Trucks QX50 should be inspected regularly, not just when tread looks worn. A quick monthly check for pressure loss, cuts, punctures, bulges, uneven wear, and sidewall damage is a sensible routine, especially on a vehicle with larger wheel packages where tire appearance can mask developing issues.
Additional inspections make sense before longer highway trips or after hitting potholes and road debris. Uneven wear can point to alignment or suspension concerns, while repeated pressure loss may suggest a puncture or wheel-sealing problem. Catching those issues early helps protect both the tires and the QX50's ride quality.
