2023 Infiniti Trucks Tire Fitment Guide

2023 Infiniti Trucks vehicles use six tire sizes across four models: 255/45R20 for QX50 and QX55, 235/55R19 for QX50, 255/50R20 and 255/60R18 for QX60, and 275/60R20 plus 275/50R22 for QX80. All of them are radial sizes. The only shared fitment across more than one model is 255/45R20, while every other size is tied to a specific model and wheel package.

That means the first fitment question for 2023 Infiniti Trucks is not construction type, but which model and wheel diameter you have. A QX50 can be on either 19-inch or 20-inch wheels, a QX60 can be on 18-inch or 20-inch wheels, and a QX80 can be on 20-inch or 22-inch wheels. Checking the sidewall of the tire already on the vehicle or the wheel diameter itself is the fastest way to narrow the right size before comparing brands.

On a 2023 Infiniti Trucks tire, 255/45R20 means the tire is 255 millimeters wide, has a 45-series aspect ratio, and fits a 20-inch wheel. The R indicates radial construction. Within this year and make, 255/45R20 applies to the QX50 and QX55 rather than the larger QX60 or QX80.

That code matters because it tells you both the physical wheel diameter and the tire's profile relationship, not just a generic size name. For 2023 Infiniti Trucks buyers, it is also one of the easiest ways to avoid crossing over into a different model's fitment. If your vehicle is a QX50 or QX55 on 20-inch wheels, 255/45R20 is the place to start; if your wheel diameter differs, the correct size will differ as well.

No, 2023 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 QX50 and QX55 overlap on one shared size.

That variation means year and make alone are not enough for confident ordering on 2023 Infiniti Trucks. Even within one model, wheel packages can change the correct size completely. If you are starting from a vehicle that has had wheels or tires changed in the past, compare the tire sidewall size to the factory wheel diameter you intend to keep. That prevents mixing a correct Infiniti model with the wrong wheel package.

For 2023 Infiniti Trucks, the currently covered 255/45R20 products come in both Blackwall and RWL sidewall styles. BFGoodrich and Nitto options in this size use Blackwall styling, while Pro-Trac offers an RWL version. The other year-make sizes are part of the fitment range, but sidewall style variety is confirmed here within 255/45R20.

Sidewall appearance changes the visual character of a modern SUV even when the size remains the same. Blackwall keeps the look understated and closer to what many late-model luxury crossovers wear from the factory, while RWL adds a more performance-oriented visual cue. For 2023 Infiniti Trucks buyers, this is mainly an appearance decision after the correct size is confirmed, since sidewall style does not change the required wheel diameter.

For 2023 Infiniti Trucks, 255/45R20 is available from BFGoodrich, Nitto, and Pro-Trac. BFGoodrich appears in both g-Force Comp 2 AS and g-Force Sport Comp 2 versions, Nitto offers the NT555 G2, and Pro-Trac offers the Street Pro III. All of those current products are radial tires for the shared QX50 and QX55 20-inch fitment.

Brand choice matters after you have confirmed the exact size on your Infiniti. Some buyers will prefer a familiar performance-oriented name, while others may focus first on sidewall appearance or series character within the same size. The practical approach for 2023 Infiniti Trucks is to match the model and wheel diameter first, then compare brands within that one size rather than trying to compare products across different Infiniti fitments.

In 255/45R20 for 2023 Infiniti Trucks, BFGoodrich offers two Blackwall products with 8.0-to-9.5-inch rim width compatibility and 101W service descriptions, while Nitto offers the NT555 G2 with a 105W XL service description and a nearly identical weight. The BFGoodrich options are g-Force Comp 2 AS and g-Force Sport Comp 2, and the Nitto option is the NT555 G2. All carry W speed ratings, which correspond to a 168 mph ceiling.

That comparison is useful if your QX50 or QX55 already wears 255/45R20 and you are narrowing choices within one fitment. The BFGoodrich products give you two established series in the same basic size envelope, while the Nitto version adds an XL-marked service description. Before choosing among them, verify the wheel width and decide whether sidewall appearance or series preference is more important for how you use your 2023 Infiniti Trucks vehicle.

For 2023 Infiniti Trucks, rim width guidance is confirmed here for the 255/45R20 size at 8.0 to 9.5 inches. That range applies to the BFGoodrich products available in this fitment for QX50 and QX55 applications. All six year-make sizes have their own wheel diameters, but rim width should always be matched to the exact tire you choose within the size.

Rim width matters because two tires with the same nominal size can still have product-specific wheel fit recommendations. If your 2023 Infiniti Trucks vehicle uses 255/45R20, confirm your wheel width before settling on a tire series. For the other Infiniti sizes, use the same process: start with the correct sidewall size and wheel diameter, then verify the specific product's approved wheel-width range rather than assuming one size rule covers every application.

The 2023 Infiniti Trucks products covered here are modern radial tires without tube-type markings, and the available 255/45R20 options are set up as tubeless-style fitments. That matches what most late-model Infiniti crossovers and SUVs use with modern one-piece wheels. None of the currently covered 255/45R20 products carry a tube-type designation in the size description.

For practical purposes, that means a 2023 Infiniti Trucks owner is usually dealing with a standard modern tubeless setup rather than collector-era tube service. The important checks are wheel condition, valve stem condition, and proper sealing surfaces. If your Infiniti has aftermarket wheels, make sure the wheel itself is intended for the tire size and service type you are using, because wheel changes can introduce fitment or sealing issues even when the sidewall size appears correct.

A 2023 Infiniti Trucks vehicle should be stored away from direct sunlight, standing moisture, and ozone sources such as electric motors, battery chargers, and some shop equipment. Keep the tires at proper pressure during storage and move the vehicle periodically if it will sit for long stretches. Because these are radial tires, they generally tolerate normal collector storage better than older bias-ply designs, but long static periods still age the rubber.

Good storage habits protect both appearance and ride quality. If your 2023 Infiniti Trucks will sit for months, clean the tires, park on a dry surface, and avoid letting one section of the tread bear weight indefinitely. For longer storage intervals, some owners use tire cradles or stands as part of a broader preservation routine. The goal is to limit UV exposure, reduce flat-spotting risk, and keep the tire carcass in stable condition until the vehicle returns to regular use.

On a 2023 Infiniti Trucks vehicle, tire life should be judged by age and condition as much as mileage. A common collector and enthusiast standard is to begin evaluating tires carefully around five to seven years of age and to give serious replacement consideration by about ten years, even if tread depth still looks acceptable. The DOT date code on the tire sidewall is the reference point for age.

That approach matters because many premium SUVs and crossovers accumulate miles unevenly, and a lightly driven 2023 Infiniti Trucks vehicle can still age out its tires before wearing them out. Heat cycles, sun exposure, storage conditions, and inflation history all affect longevity. If the tire has cracking, bulging, repeated pressure loss, or unusual ride behavior, age becomes only part of the decision. A younger tire in poor condition deserves more concern than an older tire that still appears healthy.

Tires on a 2023 Infiniti Trucks vehicle should be inspected before every drive and again before any longer trip. Look for sidewall cuts, cracking, punctures, uneven wear, embedded debris, and any sign that the tire has been run low. Pressure should be checked regularly with a quality gauge, especially when seasonal temperatures change.

That quick inspection routine is one of the simplest ways to prevent a small issue from turning into a roadside problem. On a 2023 Infiniti Trucks model with larger wheel packages, lower-profile tires can also make curb damage or impact damage more important to catch early. Add valve stem condition and spare-tire condition to the checklist, especially before highway travel, and investigate any vibration or pull rather than assuming it is normal for the vehicle.

Yes, 2023 Infiniti Trucks tires in the covered 255/45R20 fitment include W-rated products, and a W speed rating corresponds to a 168 mph ceiling. Those are modern radial tires intended for contemporary road use, not vintage-style reproduction constructions. In normal U.S. highway use, the tire's speed rating is typically far beyond the speeds most drivers will legally or practically see.

Highway safety still depends on the whole vehicle, not just the tire label. Proper inflation, alignment, tread condition, and the condition of brakes and suspension matter as much as the size itself. For a 2023 Infiniti Trucks owner, the right takeaway is to choose the exact size required by the model and wheel package, then maintain that tire correctly. A properly matched radial tire in good condition is only one part of a safe long-distance setup.

For 2023 Infiniti Trucks, tire products in 255/45R20 include a max load figure of 1819 pounds at 51 psi on one BFGoodrich option, but that is the tire's rated limit rather than a blanket vehicle setting. Inflation pressure for regular driving should follow the vehicle placard or owner's manual for the exact model and wheel package. Pressure should never be transferred from one Infiniti size to another just because the brand or tread line is similar.

That distinction is important because a QX50, QX55, QX60, and QX80 do not place the same demands on the same size tire. Use the vehicle's factory recommendation as the baseline for daily service, then compare it to the tire manufacturer's sidewall information only to understand the tire's upper rated capacity. If the vehicle has been modified with non-original wheels, verify that both tire size and wheel specification still align before adjusting pressures.

Before a longer drive in a 2023 Infiniti Trucks vehicle, inspect all four tires and the spare for tread condition, cuts, punctures, bulges, and visible sidewall damage. Confirm cold inflation pressures, check valve stems, and make sure there is no uneven wear that suggests alignment or suspension problems. If the vehicle has not been driven recently, look closely for cracking or signs of pressure loss from sitting.

A longer-trip check should also include the broader systems that support safe tire performance. On a modern Infiniti SUV or crossover, that means paying attention to brakes, steering response, suspension condition, and whether the vehicle tracks straight at speed. Tires often reveal larger issues through feathering, cupping, or shoulder wear, so do not treat them in isolation. Catching those signs early can save a road trip and protect the vehicle from additional wear.
