In 2024, Infiniti Trucks centered its utility lineup around premium crossovers and SUVs with distinct missions, from the compact QX50 and coupe-styled QX55 to the family-focused QX60 and full-size QX80. That range means tire choice is not one-size-fits-all across the brand for this model year. Six radial sizes appear across four models, with one shared size used by both QX50 and QX55 and the rest tied to specific models and wheel diameters. For most buyers, the first step is confirming the exact model and wheel size on the vehicle, because that determines whether you should be looking at 18-, 19-, 20-, or 22-inch fitments.
Which Tire Size Is Right for Your 2024 Infiniti Trucks
Six tire sizes are used across 2024 Infiniti Trucks models, and they vary by model rather than being shared across the full lineup. Every size here is a radial, so the real fitment decision is confirming the correct model and rim diameter first, then matching the exact size used on that application. Understanding that distinction before choosing a product saves time and helps ensure the right match.
Year(s): 2024|Fit(s): QX50, QX55|Construction: Radial|Rim: 20 in
The 255/45R20 is a metric radial with a 255 millimeter section width, a stated 45-series profile, and a 20-inch rim diameter. This size is available from BFGoodrich, Nitto, and Pro-Trac in blackwall and RWL form, with W-rated products carrying a 168 mph ceiling. Because it serves both the QX50 and QX55 rather than the full 2024 Infiniti Trucks range, it should be matched to those models specifically. Buyers who want a 20-inch radial in this fitment can compare sidewall appearance and brand character without changing size.
The 235/55R19 is a metric radial with a 235 millimeter section width, a stated 55-series profile, and a 19-inch rim diameter. It is a QX50-specific size rather than a universal 2024 Infiniti Trucks fitment. The practical takeaway is simple: if your QX50 rides on 19-inch wheels, this is the size family to confirm before moving on to brand or tread style. That keeps the search centered on the correct wheel diameter and overall fitment for that model.
The 255/50R20 is a metric radial with a 255 millimeter section width, a stated 50-series profile, and a 20-inch rim diameter. This size is specific to the QX60 and is not shared across the rest of the 2024 Infiniti Trucks lineup. For a QX60 on 20-inch wheels, the priority is confirming this exact size before comparing product details. That approach keeps the fitment aligned with the model's wheel package and intended tire proportions.
The 255/60R18 is a metric radial with a 255 millimeter section width, a stated 60-series profile, and an 18-inch rim diameter. It is also specific to the QX60, but for vehicles equipped with the smaller wheel diameter rather than the 20-inch setup. Buyers should treat it as a separate fitment path from the QX60's 255/50R20 option, since the rim diameter changes even though the section width stays the same. Confirming the wheel size on the vehicle is the key step before selecting a tire in this size.
The 275/60R20 is a metric radial with a 275 millimeter section width, a stated 60-series profile, and a 20-inch rim diameter. This size is specific to the QX80 and reflects the larger full-size SUV end of the 2024 Infiniti Trucks range. It should be chosen only for QX80 applications using the 20-inch wheel package. That makes model and wheel verification especially important, since the QX80 also uses a separate 22-inch fitment.
The 275/50R22 is a metric radial with a 275 millimeter section width, a stated 50-series profile, and a 22-inch rim diameter. It is the second QX80-specific size and is not interchangeable with the model's 20-inch fitment without matching wheels. For QX80 owners, this is the size to confirm when the vehicle has the larger factory-style wheel package. Getting the rim diameter right matters more here than anything else, because the tire is built around a 22-inch wheel.
Four 2024 Infiniti Trucks models are covered here, and tire size varies by model and wheel package rather than carrying across the entire lineup. That means year and make alone are not enough for a confident match; buyers should identify the exact model first, then confirm the wheel diameter already on the vehicle. Select a model below to narrow the fitment history and see the tire sizes that apply to that specific Infiniti.
2024 Infiniti Trucks QX50
The 2024 Infiniti Trucks QX50 is the compact luxury crossover in the lineup, balancing premium road manners with a smaller footprint than the larger QX60 and QX80. It uses either 19-inch or 20-inch fitments depending on wheel package, so checking the wheel before choosing a tire is essential.
The 2024 Infiniti Trucks QX55 shares much of its underlying crossover character with the QX50, but its fastback roofline gives it a more style-driven identity. Its tire fitment is simpler, using a 20-inch radial size rather than multiple wheel diameters.
The 2024 Infiniti Trucks QX60 is the three-row family SUV in the range, aimed at buyers who need more passenger and cargo flexibility. It appears with either 18-inch or 20-inch fitments, so wheel diameter is the first thing to verify before narrowing down tire options.
The 2024 Infiniti Trucks QX80 is the full-size flagship SUV, with a larger stance and heavier-duty presence than the rest of the lineup. Its tires mount on either 20-inch or 22-inch wheels, making wheel size confirmation especially important before moving to a product choice.
Four products are available across one of the six tire sizes used on 2024 Infiniti Trucks vehicles. In 255/45R20, BFGoodrich, Nitto, and Pro-Trac offer radial choices with blackwall and RWL sidewall styles, so confirm your exact size before comparing appearance and brand preference.
These FAQs focus on how 2024 Infiniti Trucks tire sizes vary from QX50 through QX80, what the metric sizing codes mean, how wheel diameter affects the choice, and what to check for long-term use on modern luxury SUVs.
Size Basics & Fitment
What tire sizes fit 2024 Infiniti Trucks vehicles?
2024 Infiniti Trucks vehicles use six radial sizes across four models: 255/45R20 for QX50 and QX55, 235/55R19 for QX50, 255/50R20 for QX60, 255/60R18 for QX60, 275/60R20 for QX80, and 275/50R22 for QX80. Rim diameters span 18, 19, 20, and 22 inches, so this is a lineup where model and wheel package matter more than make alone.
A buyer choosing tires for 2024 Infiniti Trucks should start by checking the exact model, then confirming the size on the current sidewall or door-jamb tire placard. That is especially important because two models use more than one size and the QX80 alone spans both 20-inch and 22-inch fitments. Once the size is confirmed, brand, sidewall appearance, and performance category become much easier to compare.
What does 255/45R20 mean on a 2024 Infiniti Trucks tire?
On a 2024 Infiniti Trucks tire, 255/45R20 means the tire is 255 millimeters wide, uses a 45-series aspect ratio, and fits a 20-inch wheel. The R identifies radial construction. Within the 2024 Infiniti Trucks range, this size is used on the QX50 and QX55 rather than across every model.
That code matters because it combines width, profile, construction, and wheel diameter in one line. A 255/45R20 cannot simply be swapped with a 19-inch or 22-inch size, even if another Infiniti in the same model year uses a similar width. If your QX50 or QX55 is already on 20-inch wheels, this is the size family to confirm before comparing available tire models.
Do all 2024 Infiniti Trucks models use the same tire size?
No, 2024 Infiniti Trucks models do not all use the same tire size. The QX50 uses 235/55R19 or 255/45R20, the QX55 uses 255/45R20, the QX60 uses 255/60R18 or 255/50R20, and the QX80 uses 275/60R20 or 275/50R22. Only the 255/45R20 size is shared, and that applies just to the QX50 and QX55.
In practical terms, that means year and brand are only the starting point for 2024 Infiniti Trucks tire research. You need the exact model, and on several models you also need the exact wheel package. That extra step prevents the most common mistake on modern SUV fitments: ordering a correct-looking width with the wrong overall profile or wrong rim diameter.
Buying the Right Tire
What sidewall styles are available for 2024 Infiniti Trucks tires?
Sidewall style variety appears in the 255/45R20 fitment used on 2024 Infiniti Trucks QX50 and QX55 models. That size is available in blackwall form from BFGoodrich and Nitto, and in RWL form from Pro-Trac. The other 2024 Infiniti Trucks sizes do not have sidewall-style coverage shown here, so appearance choice is most visible within that 20-inch shared fitment.
For most modern Infiniti applications, blackwall is the expected visual choice and gives the cleanest factory-style presentation. RWL adds a more assertive aftermarket look, which may appeal to buyers who want the tire to stand out rather than blend into the wheel design. If appearance matters as much as tread category, choose the size first and then compare sidewall style within that exact fitment.
What brands make tires for 2024 Infiniti Trucks vehicles?
Available brand coverage for 2024 Infiniti Trucks includes BFGoodrich, Nitto, and Pro-Trac in the 255/45R20 size used on the QX50 and QX55. BFGoodrich appears with more than one performance-oriented radial in that fitment, while Nitto and Pro-Trac each offer their own take on the same size. All of those options are built around the same 20-inch radial format.
Brand choice in a modern luxury crossover fitment often comes down to the balance you want between familiar brand heritage, tread category, and sidewall appearance. It also helps to compare the exact service description on the sidewall, since load and speed details can differ even inside one size family. Once the size is confirmed, narrowing by brand is a sensible second step rather than the first.
What is the difference between BFGoodrich g-Force COMP-2 A/S and BFGoodrich g-Force Sport COMP-2 for the 2024 Infiniti Trucks?
For 2024 Infiniti Trucks in 255/45R20, the BFGoodrich g-Force COMP-2 A/S and BFGoodrich g-Force Sport COMP-2 share the same 20-inch radial size, blackwall styling, 8.0 to 9.5 inch rim-width range, 101W service description, and 32-pound weight. The g-Force Sport COMP-2 also carries a published maximum load figure of 1,819 pounds at 51 psi. In fitment terms, they occupy the same basic dimensional space.
That means the choice between those two BFGoodrich options is less about wheel compatibility and more about the tire series you prefer within the same size and visual style. If you are comparing them for a QX50 or QX55, focus on the specific product's tread purpose and service description rather than expecting one to solve a fitment question the other cannot. Both belong to the same 255/45R20 path.
Fitting & Setup
What rim width do 2024 Infiniti Trucks tires require?
Rim-width guidance is available here for one 2024 Infiniti Trucks size: 255/45R20 uses an 8.0 to 9.5 inch rim-width range. That fitment applies to the QX50 and QX55. Other 2024 Infiniti Trucks sizes in this year-and-make group should still be matched to the exact wheel diameter already on the vehicle, even when a width range is not shown alongside them.
Rim width matters because it affects how the tire sits on the wheel, which in turn influences profile shape and overall fit. A tire mounted outside its approved width range can create handling, wear, and clearance concerns. Before choosing a 255/45R20 tire for a QX50 or QX55, verify the actual wheel width, not just the diameter, especially if the vehicle is wearing aftermarket wheels.
Do 2024 Infiniti Trucks tires require inner tubes?
The 2024 Infiniti Trucks 255/45R20 products shown here are tubeless radial tires, using size markings such as 255/45ZR20 and 255/45ZR20XL 105W with no tube-type designation. That fits what most buyers would expect on a modern Infiniti crossover or SUV application. No inner-tube requirement appears in that size group.
For a modern tubeless fitment, the condition of the wheel, valve stem, and bead seat matters more than tube selection. If your vehicle has replacement or repaired wheels, confirm they are suitable for tubeless service and that the valve hardware is in good condition. Matching the tire to the wheel correctly is still important, even when the setup does not involve an inner tube.
Maintenance, Storage & Longevity
How should I store a 2024 Infiniti Trucks when the tires are fitted?
A 2024 Infiniti Trucks vehicle should be stored away from direct sunlight, electric motors, welders, generators, and other ozone-producing equipment that can age rubber prematurely. Keep the tires clean and dry, and avoid long-term parking on damp ground or contaminated concrete. Maintaining the recommended inflation pressure during storage also helps the tire keep its shape.
If the vehicle will sit for extended periods, move it occasionally to change the contact patch or use storage stands if appropriate for the setup. Modern radials generally tolerate static storage better than older bias-ply designs, but flat spotting and pressure loss can still happen when a luxury SUV sits too long. A short inspection before returning the vehicle to regular use is always worthwhile.
How long do tires on a 2024 Infiniti Trucks typically last?
Tires on a 2024 Infiniti Trucks vehicle should be judged by age as much as tread depth, especially if the vehicle is driven lightly. A sensible collector and low-mileage rule is to begin evaluating tires closely around five to seven years of age and to treat about ten years as a serious replacement point regardless of remaining tread. The DOT date code on the sidewall gives the tire's week and year of manufacture.
That approach matters because many premium SUVs accumulate miles slowly, which can hide age-related hardening or cracking. Heat cycles, climate, storage conditions, and inflation habits often affect tire life more than mileage alone. If the tires are original to the vehicle or simply older than they look, inspect them carefully before assuming they are still suitable for regular road use.
How often should tires on a 2024 Infiniti Trucks be inspected?
Tires on a 2024 Infiniti Trucks vehicle should be checked before every drive, with a closer inspection before any longer trip or highway run. Look for sidewall cracking, cuts, punctures, bulges, uneven wear, and signs of pressure loss. Because these are modern radial SUV fitments, also pay attention to shoulder wear and any damage caused by curb contact or potholes.
A more thorough monthly inspection is a good habit even if the vehicle is not driven often. Verify cold inflation pressure, check the valve stems, and inspect the spare if the vehicle carries one. Catching small issues early helps prevent vibration, irregular wear, or roadside trouble, especially on heavier vehicles such as the QX60 and QX80.
Restoration & Authenticity
What tires were originally fitted to the 2024 Infiniti Trucks QX50?
The 2024 Infiniti Trucks QX50 belongs to a modern era in which radial tires are standard, and the fitments associated with it here are 235/55R19 and 255/45R20. Those are contemporary metric radial sizes matched to different wheel packages rather than vintage-style sizing systems. There is no reason to approach this model as a bias-ply or period-style restoration application.
For a factory-correct presentation, the important points are the exact size, wheel diameter, and an appearance that suits the trim and market of the vehicle. If originality matters at a detailed level, verify the tire placard and consult Infiniti-specific enthusiast resources for package-by-package confirmation. Modern show standards usually focus on correct size class and overall presentation rather than antique sidewall conventions.
Does correct tire fitment matter for showing a 2024 Infiniti Trucks?
Yes, correct tire fitment still matters when showing a 2024 Infiniti Trucks vehicle, even though it is far newer than a traditional collector car. Judges and knowledgeable enthusiasts will notice the wrong rim diameter, an obviously incorrect profile, or a sidewall treatment that clashes with the vehicle's intended factory appearance. On modern luxury SUVs, correctness tends to mean clean, properly sized radial tires that match the model's wheel package.
That does not always require a single exact brand, but it does require avoiding mismatched sizes or a look that appears out of character for the vehicle. A QX50 on the wrong profile or a QX80 wearing the wrong diameter can stand out immediately. If the vehicle is headed for marque-oriented events, compare against factory references and event standards before making an appearance-driven tire change.
What is the difference between Nitto NT555 G2 and Pro-Trac Street Pro III for the 2024 Infiniti Trucks?
For 2024 Infiniti Trucks in 255/45R20, the Nitto NT555 G2 and Pro-Trac Street Pro III share the same basic size and both weigh 31.97 pounds. The Nitto carries a 255/45ZR20XL 105W marking with blackwall styling, while the Pro-Trac uses a 255/45ZR20 marking with RWL styling. That makes sidewall appearance and service description the clearest visible differences between the two.
If you are comparing them for a QX50 or QX55, the choice is less about whether they fit the same wheel diameter and more about the presentation and exact sidewall specification you want. Blackwall tends to preserve a more understated modern OEM look, while RWL creates a more expressive aftermarket look. Review the sidewall marking carefully so the final choice matches both the vehicle and your intended use.
Safety & Road Use
Are 2024 Infiniti Trucks tires safe for highway driving?
Yes, 2024 Infiniti Trucks tires in the 255/45R20 group shown here are suitable for highway use when they are in proper condition, correctly inflated, and matched to the vehicle's required size. The products in that size carry W speed ratings, which correspond to a 168 mph ceiling. In real-world use, the condition of the tire, the load it is carrying, and the vehicle's overall mechanical health matter more than approaching that rating.
Highway safety depends on more than the sidewall code alone. A damaged tire, poor alignment, old rubber, or improper pressure can make even a correctly sized premium tire perform poorly. Before longer freeway driving in any 2024 Infiniti Trucks model, verify the age, condition, and pressure of the tires rather than assuming the size code alone answers the safety question.
What inflation pressure should I use for 2024 Infiniti Trucks tires?
Inflation pressure for 2024 Infiniti Trucks tires should follow the vehicle manufacturer's placard and owner's manual for the exact model and wheel package. In the 255/45R20 group, one BFGoodrich g-Force Sport COMP-2 product carries a maximum load of 1,819 pounds at 51 psi, but that figure is a tire rating limit rather than a blanket operating pressure for every 2024 Infiniti Trucks application. Pressure should always be set for the vehicle, not borrowed from another size or model.
That distinction matters because a QX50, QX55, QX60, and QX80 place different demands on their tires even when two sizes may look similar at a glance. Use the tire's rated pressure as a technical ceiling reference and the vehicle placard as the day-to-day setup guide. If the vehicle has non-original wheels or a mixed brand set, a careful pressure check becomes even more important.
What should I check before taking a 2024 Infiniti Trucks on a longer drive?
Before taking a 2024 Infiniti Trucks vehicle on a longer drive, inspect each tire for cracking, punctures, bulges, uneven wear, and any signs of impact damage. Verify cold pressure, confirm the valve stems are sound, and check that the spare is usable if the vehicle carries one. On models with larger wheel packages such as the QX80, also pay close attention to sidewall condition after pothole or curb contact.
Tire condition is only one part of a proper pre-trip check, but it is one of the easiest and most important. A modern Infiniti SUV also benefits from a quick look at brakes, fluids, battery condition, and suspension behavior before a long run. Starting with the tires helps establish whether the vehicle is ready for stable, predictable road manners at normal highway speeds.
