Infiniti Trucks QX55 Tires

Infiniti Trucks QX55 uses one tire size across the full 2022 through 2025 span: 255/45R20. The available products in this fitment are all radial tires built for a 20-inch rim diameter, and listed examples include 255/45ZR20 variations that stay within the same basic size family for QX55 use.

That makes fitment simpler than on many multi-generation vehicles, but the actual wheel on the vehicle still matters. If a previous owner changed the wheels, confirm the tire sidewall marking and the wheel diameter on the car before replacing tires so the new set matches the vehicle's current configuration.

On an Infiniti Trucks QX55, 255/45R20 is a metric radial tire size. The 255 is the nominal section width in millimeters, 45 is the aspect ratio showing the sidewall height as a percentage of width, R means radial construction, and 20 is the wheel diameter in inches.

Those numbers are important because changing any one of them can alter overall diameter, handling response, and the visual proportion of the vehicle. A QX55 owner comparing tires should match the full size code rather than only the wheel diameter, since a different width or aspect ratio can change how the tire fits and drives.

Infiniti Trucks QX55 uses a 20-inch rim diameter throughout the 2022, 2023, 2024, and 2025 model years covered here. Every listed tire option for the QX55 is built around that same 20-inch wheel size, which keeps the fitment range consistent across the production run.

The practical step is to verify that the vehicle still carries its correct 20-inch wheels before choosing a tire. That is especially worthwhile on used vehicles, where wheel swaps are common and can create confusion if the owner assumes the original size still applies.

Every Infiniti Trucks QX55 model year from 2022 through 2025 shown here uses 255/45R20, so the factory-style fitment path is straightforward. The correct replacement size should match the sidewall marking already on the vehicle if it still carries the proper 20-inch wheel and stock-equivalent overall setup.

A careful owner should still check the sidewall on the existing tires, the wheel diameter itself, and any vehicle label information before final selection. That extra step helps catch prior changes, especially on vehicles that may have had aftermarket wheel packages installed for appearance or performance reasons.

Infiniti Trucks QX55 tires in this fitment are available with Blackwall, RWL, and Redline sidewall styles. Blackwall options appear across multiple brands, while the Pro-Trac Street Pro III line adds both raised white letter and redline presentations in the same 255/45R20 size family.

Sidewall style changes the look of the vehicle more than the basic fitment, so the best choice depends on whether the goal is a clean modern appearance or a more distinctive custom accent. Owners seeking a more original late-model luxury crossover look will usually gravitate toward Blackwall, while RWL and Redline create a stronger visual statement.

Three brands appear in the available Infiniti Trucks QX55 fitment range: BFGoodrich, Nitto, and Pro-Trac. Within those brands, the listed series include BFGoodrich g-Force Comp 2 AS, BFGoodrich g-Force Sport Comp 2, Nitto NT555 G2, and Pro-Trac Street Pro III.

Brand choice is less about basic fitment here, since they share the same 255/45R20 size family, and more about tread design, performance emphasis, and appearance. Comparing the series and sidewall style is the most useful next step once the owner has confirmed that the QX55 still carries its correct 20-inch wheel setup.

Infiniti Trucks QX55 has multiple tire series available in the 255/45R20 fitment, including g-Force Comp 2 AS, g-Force Sport Comp 2, Nitto NT555 G2, and Street Pro III. All are radial tires, but they represent different lines within their respective brands and give buyers a mix of performance-oriented and style-oriented choices within the same core size.

That means the main decision is not between radically different constructions, but between how the tire is presented and what driving character the series is intended to emphasize. Once the size is confirmed, owners can narrow the field by deciding whether they want a more understated Blackwall look or a more custom sidewall treatment such as RWL or Redline.

An Infiniti Trucks QX55 should be stored on a clean, dry surface away from direct sunlight, ozone sources, and major temperature swings when the tires are fitted. Proper inflation matters during storage, because an underinflated modern radial can develop flat spotting or sidewall stress more readily when the vehicle sits for long periods.

Owners who store a QX55 for seasonal use should check inflation regularly and move the vehicle occasionally to change the contact patch. If the vehicle will sit for an extended time, keeping weight off one spot of the tire and maintaining a stable storage environment will do more for tire life than simply covering the vehicle.

Tires on an Infiniti Trucks QX55 should be inspected regularly even if the vehicle is driven only occasionally. A visual inspection for cracking, punctures, uneven wear, impact damage, and pressure loss should become part of routine ownership, since modern performance-oriented sizes can hide wear issues until they begin to affect ride and handling.

A practical habit is to inspect the tires before longer drives and at regular intervals during the season, paying attention to both tread condition and sidewall appearance. That approach helps catch alignment issues, aging, or damage early, before the owner commits the QX55 to sustained highway driving.

Tires on an Infiniti Trucks QX55 should be replaced when age, cracking, hardening, impact damage, repeated air loss, or structural concerns appear, even if the tread still looks usable. Tread depth alone is not a complete measure of tire health, especially on a vehicle that may see lower annual mileage and longer periods of storage.

Collectors and occasional-use owners should treat tire age as seriously as visible wear. If a QX55 begins to show age-related deterioration or its tires have been in service long enough to raise concern, replacement is the wiser course than relying on appearance alone.

The listed Infiniti Trucks QX55 tires are modern radial products in the correct 255/45R20 fitment family, so they are intended for road use when properly mounted, inflated, and maintained. Safety depends not only on size match, but also on tire age, condition, pressure, alignment, and the overall mechanical condition of the QX55.

An owner should think of fitment as only the first step. Before regular road use, confirm that the tires are in sound condition, the wheels are appropriate for the size, and the vehicle does not show suspension or alignment issues that could compromise how the tire performs.

Before driving an Infiniti Trucks QX55, check tire pressure, visible tread and sidewall condition, and any signs of cuts, bulges, punctures, or uneven wear. It is also wise to confirm that all four tires are the same size family and that the wheels match the required 20-inch diameter used by the QX55 fitment shown here.

That quick inspection can prevent avoidable problems on the road and helps catch mismatched tires after rotation, repair, or prior ownership changes. On a modern crossover with performance-oriented sizing, even small discrepancies in tire condition or size can affect ride quality, braking feel, and steering response.

An Infiniti Trucks QX55 should always be driven within lawful road speeds and within the capability of the specific tire fitted to the vehicle. The listed QX55 fitment includes modern radial tires with performance-oriented sizing, but real-world safe speed still depends on inflation, load, road conditions, weather, and tire condition.

The sensible approach is to treat the tire as one part of the vehicle's total system rather than as permission for aggressive driving. If the QX55 is carrying older tires, unevenly worn tires, or tires of mixed types, reducing speed and correcting those issues first is more important than any speed capability implied by the size itself.
