2022 Infiniti Trucks Tire Fitment Guide

2022 Infiniti Trucks vehicles use six radial tire sizes across four models. 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. Rim diameters therefore span 18, 19, 20, and 22 inches across the full range, and the 255/45R20 size is the only one shared by more than one model.

That means year and make alone are not enough to identify the right tire for a 2022 Infiniti Trucks vehicle. The first checkpoint is the exact model, and the second is the wheel diameter actually fitted to that vehicle. Once those two details are confirmed, the size choice usually becomes straightforward and you can focus on product details such as sidewall style, load index, and speed rating where available.

On a 2022 Infiniti Trucks tire, 255/45R20 means the tire is 255 millimeters wide, has a 45-series aspect ratio, uses radial construction, and mounts on a 20-inch wheel. Within this year and make, that size appears on the QX50 and QX55. Available products in this size include Blackwall and RWL sidewall styles, and the speed rating can vary by product, with W-rated examples carrying a 168 mph ceiling.

The practical value of decoding that size is that it separates wheel fitment from product selection. A 20-inch wheel is mandatory for 255/45R20, but once that wheel diameter is confirmed, the remaining choices shift to tire character and appearance rather than basic compatibility. QX50 owners especially need to verify whether they have the 19-inch or 20-inch setup, because both appeared in the same model year.

No, 2022 Infiniti Trucks models do not use the same tire size. The QX50, QX60, and QX80 each carried two possible sizes, while the QX55 used one. Only 255/45R20 is shared, and it applies only to the QX50 and QX55 rather than to the full Infiniti truck range.

That model-by-model spread matters because the dimensions and wheel diameters are different enough that guessing from another Infiniti in the driveway is risky. A QX60’s 18-inch or 20-inch fitment, for example, does not translate to a QX80’s 20-inch or 22-inch setup. Checking the placard, current tire sidewall, or wheel diameter before you compare products is the simplest way to avoid crossing models or wheel packages.

For 2022 Infiniti Trucks, the available sidewall styles shown in the covered products appear in the 255/45R20 size. That size comes in both Blackwall and raised white letter, or RWL, form. Blackwall keeps a more understated late-model luxury look, while RWL gives the tire a more overtly sporty and performance-oriented appearance.

Sidewall style does not change the basic fitment, but it can change how the vehicle presents visually. On a modern Infiniti crossover, Blackwall is generally the more factory-looking choice, while RWL stands out more strongly against the wheel and body side. If appearance matters as much as dimension, choose the sidewall treatment after confirming the correct size for the model and wheel package.

Within the covered 2022 Infiniti Trucks products, the 255/45R20 size is available from BFGoodrich, Nitto, and Pro-Trac. BFGoodrich appears with more than one performance-oriented radial option in that size, Nitto brings a modern street-performance radial, and Pro-Trac offers a version with raised white letters. All of those products remain within the same basic 255/45R20 fitment for QX50 and QX55 applications.

Brand choice matters most after the size itself is settled. Once you know your Infiniti uses 255/45R20, the next comparison points become sidewall appearance, speed rating, and any published load information. Owners of other 2022 Infiniti Trucks models should confirm their exact size first, since the broader Infiniti range includes several other dimensions that are not interchangeable with the shared QX50 and QX55 fitment.

In 255/45R20 for 2022 Infiniti Trucks, BFGoodrich and Nitto both offer radial performance tires, but the published details are not identical. BFGoodrich appears in more than one series, with examples carrying a 101W service description and an 8.0- to 9.5-inch approved rim-width range, plus a stated 1,819-pound maximum load at 51 psi on one product. The Nitto NT555 G2 appears in 255/45ZR20XL 105W form and carries a slightly lighter published weight than the BFGoodrich examples.

Those differences are enough to make side-by-side comparison worthwhile even when the nominal tire size is the same. Load index, extra-load marking, rim-width range, and sidewall appearance can all influence which 255/45R20 tire makes the most sense for your QX50 or QX55. Matching those details to how the vehicle is driven is more useful than focusing on brand name alone.

A published rim-width range appears for 2022 Infiniti Trucks in the 255/45R20 size. The BFGoodrich products in that size fit wheels from 8.0 to 9.5 inches wide. The other sizes used across the 2022 Infiniti Trucks range still require their proper wheel diameters, but the usable width range should be confirmed against the exact tire selected.

Rim diameter gets most of the attention, yet rim width is what helps the tire sit correctly on the wheel and maintain its intended profile. If your vehicle uses 255/45R20, comparing your actual wheel width against the tire maker’s approved range is a worthwhile final check. For the other Infiniti sizes, use the exact product specification rather than assuming one width range carries across the whole model line.

The covered 2022 Infiniti Trucks products in 255/45R20 are modern radial tires with no tube-type marking in the size description, which points to tubeless use in that application. No conflicting tube-type marking appears among those 255/45R20 products. The remaining 2022 Infiniti Trucks sizes should still be checked product by product, especially if you are comparing tires from different manufacturers or categories.

For a late-model Infiniti, the practical step is to confirm that the tire, wheel, and valve hardware all match the intended tubeless setup. If a specific tire ever carries different tube guidance, follow that product’s sidewall and manufacturer instructions rather than assuming all tires in a close size behave the same way. That is especially important when replacing only two tires instead of a full set.

A 2022 Infiniti Trucks vehicle should be stored on clean, properly inflated tires in a cool, dry space away from direct sunlight, electric motors, battery chargers, welders, and other ozone-producing equipment. Modern radial tires generally tolerate inactivity better than older bias-ply designs, but they still age faster when exposed to heat, ultraviolet light, or long periods under low pressure.

If the vehicle sits for long stretches, move it periodically so the tires are not carrying the same load in the same spot month after month. For longer-term storage, some owners also use tire cradles or stands to reduce stress on the carcass. Keeping the tires clean and the storage environment stable does more for long-term condition than simply covering the vehicle and forgetting about it.

On a 2022 Infiniti Trucks vehicle, tire age usually matters more than mileage alone, especially if the vehicle sees seasonal or low annual use. A sensible rule is to begin evaluating tires closely once they are about five to seven years old and to treat around ten years as a serious replacement consideration regardless of tread depth. The DOT date code on the sidewall is the key reference for true age.

Luxury crossovers and SUVs often accumulate miles gently, which can leave tread looking decent even when the rubber has hardened with time. That is why visual condition should be considered along with age, not instead of it. If your Infiniti still wears older tires with plenty of remaining tread, check for cracking, loss of flexibility, or changes in ride quality before assuming they have years of safe use left.

Tires on a 2022 Infiniti Trucks vehicle deserve a quick inspection before every drive and a more careful one before any longer trip. Check inflation pressure, tread wear pattern, cuts, sidewall damage, punctures, and any signs of cracking or bulging. Since these vehicles use modern radial sizes, even small abnormalities can signal alignment, suspension, or impact-related issues that are easier to catch early.

A brief walk-around takes very little time and can prevent far more expensive trouble on the road. Before a highway trip, inspect the spare as well, because an overlooked spare often becomes the weak point in an otherwise well-kept vehicle. Regular inspection also helps you spot whether wear is even across the tread, which can tell you as much about the vehicle’s setup as it does about the tire itself.

Yes, 2022 Infiniti Trucks tires in the covered range are modern radial sizes intended for contemporary road use, and the available 255/45R20 products include W-rated examples with a 168 mph ceiling. That speed rating is far beyond normal U.S. highway travel, so in ordinary use the tire’s basic speed capability is not usually the limiting factor. Load rating, condition, inflation, and the vehicle’s overall mechanical health remain just as important.

Highway safety comes from the whole system working together rather than from the size code alone. A properly inflated, undamaged tire on a straight, well-maintained vehicle is far more reassuring than a higher-rated tire on a neglected one. Before longer highway use, make sure the tires are matched in size and service description across the axle and that none are aged out or showing impact damage.

For 2022 Infiniti Trucks tires, use the vehicle manufacturer’s placard or owner’s manual as the starting point for normal service pressure, because that recommendation is tied to the vehicle’s weight distribution and intended ride characteristics. One covered 255/45R20 BFGoodrich product carries a published maximum load of 1,819 pounds at 51 psi, but that figure is a tire rating limit rather than a universal everyday setting for every 2022 Infiniti Trucks model.

The important distinction is that a tire’s maximum pressure and a vehicle’s recommended operating pressure are not the same thing. Inflate to the vehicle specification for regular use unless the tire manufacturer gives a different approved application-specific instruction. If you change tire brand or service description within the same size, double-check both the tire sidewall and the Infiniti placard so the pressure target still makes sense for that combination.

Before a longer drive in a 2022 Infiniti Trucks vehicle, inspect each tire for cracking, cuts, punctures, bulges, uneven wear, and any sign of impact damage from curbs or potholes. Verify cold inflation pressure, confirm that all four tires match the correct size for the vehicle, and check the spare if one is present. On late-model Infiniti SUVs and crossovers, it also makes sense to look for any warning lights tied to tire pressure monitoring or chassis systems.

That tire check should be part of a broader pre-trip routine that includes brakes, fluids, lights, and suspension condition. A tire can be the first place a developing mechanical problem shows up, especially if wear patterns have changed since the last inspection. Catching that early helps you avoid both roadside trouble and premature replacement of otherwise serviceable tires.
