2020 Infiniti Trucks covered a broad slice of the premium SUV market, from the compact QX50 to the full-size QX80, with each model aimed at a different kind of luxury driver. That matters when choosing tires, because the year’s lineup did not share one common fitment across the board. Six radial sizes appear across three models, and each model uses its own pair of sizes tied to its wheel diameter and overall stance rather than a one-size-fits-all replacement approach. Before choosing a tire for 2020 Infiniti Trucks, confirm your exact model first, then verify whether your vehicle is on its smaller or larger factory wheel package.
Which Tire Size Is Right for Your 2020 Infiniti Trucks
Six tire sizes are used across 2020 Infiniti Trucks, and they vary by model rather than carrying across the full range. The real decision starts with confirming the correct model and wheel diameter, since the QX50, QX60, and QX80 each use their own size pair. Understanding that distinction before choosing a product saves time and helps match the tire to the right vehicle.
Year(s): 2020|Fit(s): QX50|Construction: Radial|Rim: 20 in
255/45R20 is a radial metric size with a 255-millimeter section width, a 45-series aspect ratio, and a 20-inch rim diameter. This QX50-specific size is available from BFGoodrich, Nitto, and Pro-Trac, with Blackwall and RWL sidewall styles, and W speed-rated products with a 168 mph ceiling. It suits drivers who want a modern radial fitment on the 20-inch wheel package used on certain QX50 models.
235/55R19 is a radial metric size with a 235-millimeter section width, a 55-series aspect ratio, and a 19-inch rim diameter. This size is specific to QX50 models equipped with the smaller wheel package. It is the correct starting point when your QX50 is not running the 20-inch setup, and it should be matched to the actual wheel before moving on to product selection.
235/55R20 is a radial metric size with a 235-millimeter section width, a 55-series aspect ratio, and a 20-inch rim diameter. This size is used only on certain QX60 applications rather than across all 2020 Infiniti Trucks models. It is the right direction for a QX60 on 20-inch wheels, where the key choice is confirming wheel diameter rather than choosing between different construction types.
235/65R18 is a radial metric size with a 235-millimeter section width, a 65-series aspect ratio, and an 18-inch rim diameter. This QX60-specific size belongs to vehicles fitted with the 18-inch wheel package. It is the size to follow when your QX60 is on the smaller factory wheel, and confirming that wheel diameter is the most important step before comparing tire options.
275/50R22 is a radial metric size with a 275-millimeter section width, a 50-series aspect ratio, and a 22-inch rim diameter. This size is specific to the QX80 and reflects the larger-wheel fitment used on certain full-size luxury SUV configurations. It is the correct path for QX80 owners on 22-inch wheels, where overall fitment begins with matching the tire to the wheel diameter already on the vehicle.
275/60R20 is a radial metric size with a 275-millimeter section width, a 60-series aspect ratio, and a 20-inch rim diameter. This size fits QX80 models equipped with the 20-inch wheel package rather than the 22-inch version. It is the appropriate choice when your QX80 uses the smaller of its two factory wheel diameters, and wheel confirmation should come before any product comparison.
Three Infiniti truck models are covered for 2020, and tire size varies by model rather than staying uniform across the lineup. In practical terms, that means year and make alone are not enough; you need to identify whether you have a QX50, QX60, or QX80, and then confirm which wheel package is on the vehicle. Select a model below for model-specific fitment history and products.
2020 Infiniti Trucks QX50
The 2020 Infiniti QX50 is the compact luxury crossover in the lineup, with a more urban, road-focused character than the larger Infiniti SUVs. Its tires mount on either 19-inch or 20-inch wheels, depending on the wheel package fitted to the vehicle. That makes wheel confirmation especially important before narrowing your tire choice.
The 2020 Infiniti QX60 sits in the midsize luxury SUV class and is oriented toward three-row family use with a smoother, comfort-centered driving mission. Its fitments mount on either 18-inch or 20-inch wheels. That split means the model name alone is only half the answer; the wheel diameter on the vehicle matters too.
The 2020 Infiniti QX80 is the full-size flagship SUV, with the larger stance and luxury-truck presence expected from Infiniti’s top utility model. Its tires mount on 20-inch or 22-inch wheels, both larger than the fitments used on the QX50 and QX60. Because the two QX80 sizes are tied directly to wheel diameter, checking the wheel already on the vehicle is the first step.
Four products are available across six tire sizes for 2020 Infiniti Trucks vehicles. The 255/45R20 has four radial choices from BFGoodrich, Nitto, and Pro-Trac in Blackwall and RWL styles. Confirm your exact size first, since product coverage is concentrated in one fitment rather than spread evenly across the full model range.
These FAQs cover how 2020 Infiniti Trucks sizes differ between QX50, QX60, and QX80 models, how to decode the metric size markings, what product and sidewall choices exist, and what to inspect on a luxury SUV that may see seasonal or low-mileage use.
Size Basics & Fitment
What tire sizes fit 2020 Infiniti Trucks vehicles?
2020 Infiniti Trucks vehicles use six sizes across three models. The QX50 uses 255/45R20 or 235/55R19, the QX60 uses 235/55R20 or 235/65R18, and the QX80 uses 275/50R22 or 275/60R20. These are all radial sizes, and they do not interchange across the whole Infiniti truck lineup because each model has its own wheel diameter range.
The practical takeaway is that year and make are only the starting point for 2020 Infiniti Trucks. A QX50 owner must distinguish between 19-inch and 20-inch wheels, a QX60 owner between 18-inch and 20-inch wheels, and a QX80 owner between 20-inch and 22-inch wheels. Checking the sidewall on the current tire or measuring the wheel before ordering is the fastest way to narrow the correct fitment.
What does 255/45R20 mean on a 2020 Infiniti Trucks tire?
On a 2020 Infiniti Trucks tire, 255/45R20 means the tire is 255 millimeters wide, has a 45-series aspect ratio, uses radial construction, and fits a 20-inch wheel. On this year and make, that size belongs to the QX50. The lower profile relative to the 19-inch QX50 alternative reflects the larger factory wheel package rather than a different construction type.
That code matters because each part of it affects fitment. A 20-inch wheel is mandatory for 255/45R20, and the tire’s overall proportions differ from the QX50’s 235/55R19 option. If your QX50 has 20-inch wheels, this is the size family to investigate further; if it has 19-inch wheels, moving to this size would require confirming wheel compatibility first rather than treating it as a simple replacement.
Do all 2020 Infiniti Trucks models use the same tire size?
No, 2020 Infiniti Trucks models do not use the same tire size. The compact QX50, midsize QX60, and full-size QX80 each have their own pair of radial sizes, and none of those fitments are shared across all three models. Even within a single model, two wheel packages can exist, so one QX60 may take 235/65R18 while another takes 235/55R20.
That means model identification is essential before moving on to brand or sidewall preferences. Buyers comparing tires across the Infiniti SUV range should think in terms of model-specific fitment rather than assuming a common luxury-SUV replacement size. Once the model is confirmed, the next step is verifying whether the vehicle is on its smaller or larger factory wheel package so the tire and wheel diameter stay correctly matched.
Buying the Right Tire
What sidewall styles are available for 2020 Infiniti Trucks tires?
Sidewall style variety is currently concentrated in the 255/45R20 fitment used on the 2020 Infiniti Trucks QX50. That size is available in Blackwall and RWL form, with Blackwall options from BFGoodrich and Nitto and an RWL option from Pro-Trac. The other 2020 Infiniti Trucks sizes remain model-specific fitments, but sidewall variety is not spread evenly across the full year-and-make range.
For most late-model Infiniti SUV owners, Blackwall is the more factory-like visual direction because it suits the contemporary luxury look of the QX50, QX60, and QX80. RWL creates a more aggressive aftermarket appearance and may appeal to owners who want a sportier presentation on a 20-inch QX50 setup. Appearance should still come after fitment, so confirm the correct size first and then choose the sidewall style that matches your vehicle’s character.
What brands make tires for 2020 Infiniti Trucks vehicles?
BFGoodrich, Nitto, and Pro-Trac currently cover the 255/45R20 size used on the 2020 Infiniti Trucks QX50. BFGoodrich appears in both g-Force Comp 2 AS and g-Force Sport Comp 2 form, Nitto covers the size with the NT555 G2, and Pro-Trac offers the Street Pro III. Brand coverage is not evenly distributed across all six 2020 Infiniti Trucks sizes, so the exact size on your vehicle shapes the brand choices available to you.
That matters because buyers often start with a preferred brand when they should start with confirmed fitment. Once the size is established, brand selection becomes more meaningful, especially when you want a certain look such as Blackwall or RWL. If you own a QX50 on 20-inch wheels, there is room to compare among multiple brands; if you own one of the other fitments, size confirmation should remain the first step.
What is the difference between BFGoodrich g-Force Comp 2 AS and BFGoodrich g-Force Sport Comp 2 for the 2020 Infiniti Trucks QX50?
For the 2020 Infiniti Trucks QX50 in 255/45R20, both BFGoodrich options share the same 20-inch rim diameter, 8.0-to-9.5-inch rim width range, Blackwall sidewall style, 101W service description, and a 32-pound weight. The g-Force Sport Comp 2 carries a published maximum load figure of 1,819 pounds at 51 psi, while the g-Force Comp 2 AS appears in all-season naming and overall sizing that match the same fitment family.
The useful takeaway is that these two BFGoodrich choices are close in core fitment, so the decision is less about whether one fits and more about how you want the tire positioned within the same 255/45R20 envelope. A QX50 owner comparing them should verify intended road use, sidewall appearance expectations, and any manufacturer guidance tied to the exact series before settling on one version over the other.
Fitting & Setup
What rim width do 2020 Infiniti Trucks tires require?
Rim width guidance is available for the 2020 Infiniti Trucks 255/45R20 fitment used on the QX50. In that size, BFGoodrich specifies an 8.0-to-9.5-inch rim width range for both the g-Force Comp 2 AS and g-Force Sport Comp 2. The same size also uses a 20-inch rim diameter, which must match the wheel already on the vehicle.
Rim width matters because a tire can share the correct diameter yet still be better suited to a certain wheel width window. If your QX50 uses 255/45R20, confirm both wheel diameter and actual rim width before choosing among available products. For other 2020 Infiniti Trucks sizes, the safest route is to verify the existing wheel directly rather than assuming one model’s rim range applies to another size or another Infiniti SUV.
Do 2020 Infiniti Trucks tires require inner tubes?
The available 255/45R20 products for 2020 Infiniti Trucks do not carry tube-type markings, and their modern radial construction aligns with tubeless fitment on contemporary wheels. That size appears in BFGoodrich, Nitto, and Pro-Trac offerings without TT designations. The other 2020 Infiniti Trucks fitments are also modern radial metric sizes, which places them firmly in late-model tire design rather than vintage tube-type construction.
Even so, wheel condition still matters. A damaged bead seat, previous repair, or wheel issue can affect whether a tire seals properly, especially on an SUV that may have seen curb contact or years of use. For 2020 Infiniti Trucks, tube decisions should never be treated as a styling choice; they should follow the tire’s sidewall marking and the wheel’s actual design, with the final check made before mounting.
Maintenance, Storage & Longevity
How should I store a 2020 Infiniti Trucks when the tires are fitted?
A 2020 Infiniti Trucks vehicle should be stored out of direct sunlight, away from ozone-producing equipment such as motors or chargers, and on a clean, dry surface. Keep the tires at proper pressure and move the vehicle periodically if it will sit for long stretches. Because these are modern radial SUV tires, they generally tolerate storage better than older bias-ply designs, but long static periods can still create temporary flat spotting and age-related sidewall stress.
The biggest storage mistake is treating a low-mileage luxury SUV as maintenance-free simply because it is driven infrequently. Tire aging is affected by time and environment as much as by mileage. If a QX50, QX60, or QX80 sits for seasonal use, a breathable indoor space and occasional repositioning go a long way toward preserving ride quality and reducing the chance of discovering a cracked or pressure-lost tire right before a trip.
How long do tires on a 2020 Infiniti Trucks typically last?
Tires on a 2020 Infiniti Trucks vehicle should be judged by age as much as by tread wear. A good collector and enthusiast rule is to begin evaluating closely around five to seven years of service and to consider replacement as a tire approaches ten years from its DOT date code, even if the tread still looks usable. That guidance is especially relevant on upscale SUVs that may cover limited annual mileage.
Luxury crossover and SUV owners often see tires age out before they wear out, particularly when one vehicle is used as a second or seasonal car. Check the DOT date on each tire, not just the spare or the newest one installed, because mixed ages are common. If your 2020 Infiniti Trucks still wears older rubber with plenty of tread, age and condition deserve as much attention as remaining tread depth.
How often should tires on a 2020 Infiniti Trucks be inspected?
Tires on a 2020 Infiniti Trucks vehicle deserve a quick inspection before every drive and a more thorough inspection before any longer outing. Look for sidewall cracking, punctures, bulges, uneven wear, and pressure loss, and make sure the tread surface is free of embedded damage. Since these vehicles use modern radial sizes across 18-inch, 19-inch, 20-inch, and 22-inch wheels, even a small issue can affect ride quality and handling noticeably.
A brief walk-around catches more problems than many owners expect, especially on heavier SUVs like the QX80 where load and wheel size place more demand on the tire. Before a highway trip, include the spare if the vehicle has one, and inspect valve stems for age or cracking. Routine checks are one of the simplest ways to avoid discovering an avoidable tire problem after the vehicle is fully loaded and already on the road.
Safety & Road Use
Are 2020 Infiniti Trucks tires safe for highway driving?
2020 Infiniti Trucks tires are modern radial SUV and crossover fitments, and the available 255/45R20 products carry W speed ratings, which correspond to a 168 mph ceiling. That is far beyond normal U.S. highway use, and for everyday driving the more relevant factors are proper inflation, tire age, alignment condition, and the vehicle’s own maintenance state. On a late-model Infiniti luxury SUV, tire capability is only one part of the highway-safety picture.
A highway-ready tire still needs to be the correct size for the model and wheel package. The QX50, QX60, and QX80 each use different fitments, so safety begins with matching the tire to the exact vehicle before considering brand or appearance. Once fitment is correct, inspect pressure and condition regularly, especially if the vehicle spends much of its time parked and only comes out for longer weekend or holiday drives.
What inflation pressure should I use for 2020 Infiniti Trucks tires?
Inflation pressure for 2020 Infiniti Trucks should follow the vehicle placard or owner’s manual first, because factory pressure targets are set around the exact model, load distribution, and wheel package. Within the available 255/45R20 choices for the QX50, one BFGoodrich g-Force Sport Comp 2 entry carries a maximum load figure of 1,819 pounds at 51 psi. That number is a maximum-rated figure for the tire, not a blanket operating pressure for every 2020 Infiniti Trucks application.
The safest approach is to use the vehicle’s specified cold pressure for normal driving and compare it with the tire manufacturer’s service information for the exact product you choose. Do not transfer a pressure figure from a QX50 tire to a QX60 or QX80, or from one size to another, because the wheel diameter, load requirement, and tire profile all change across the Infiniti SUV range.
What should I check before taking a 2020 Infiniti Trucks on a longer drive?
Before taking a 2020 Infiniti Trucks vehicle on a longer drive, inspect each tire for cracking, cuts, bulges, punctures, irregular tread wear, and proper cold inflation. Verify that all four tires match the correct size family for your model, whether that means a QX50, QX60, or QX80 fitment, and inspect the spare if one is present. A quick look at valve stems and bead areas is worthwhile too, especially on larger-diameter wheels.
Tires are only part of the pre-trip picture on a luxury SUV, but they are the part touching the road the entire time. Pair the tire inspection with a broader check of brakes, fluids, battery condition, and suspension health, particularly if the vehicle has been parked for extended periods. Catching a weather-cracked sidewall, underinflated tire, or aging spare before departure is far easier than dealing with it after the trip has started.
