2025 Infiniti Trucks Tire Fitment Guide

2025 Infiniti Trucks vehicles use six tire sizes across four models: 235/55R19 for the QX50, 255/45R20 for the QX50 and QX55, 255/50R20 and 255/60R18 for the QX60, and 275/50R22 plus 275/60R20 for the QX80. All six are radial sizes, but they do not share a common rim diameter across the full lineup. The only size shared between models is 255/45R20, which fits both the QX50 and QX55.

That means year and make alone are not enough for a correct tire choice on 2025 Infiniti Trucks. A QX60 owner must first confirm whether the vehicle has 18-inch or 20-inch wheels, and a QX80 owner must distinguish between 20-inch and 22-inch fitments. If you are working with a QX50 or QX55, the next step is confirming whether your wheel package uses 19-inch or 20-inch tires.

On a 2025 Infiniti Trucks tire, 255/45R20 is a modern metric radial size. The 255 is the section width in millimeters, 45 is the aspect ratio, the R identifies radial construction, and 20 is the wheel diameter in inches. That size appears on the 2025 Infiniti Trucks QX50 and QX55, making it the only fitment shared by more than one model in this lineup.

Understanding that code helps you avoid one of the most common mistakes with modern luxury SUVs: matching the model name but missing the wheel package. A 255/45R20 tire cannot replace a 235/55R19 on a QX50 or a 255/60R18 on a QX60, even though the widths may look similar at first glance. For 2025 Infiniti Trucks, the last number in the size is the quickest way to confirm the wheel diameter you need.

No, 2025 Infiniti Trucks models do not all use the same tire size. The QX50 can use 235/55R19 or 255/45R20, the QX55 uses 255/45R20, the QX60 uses either 255/50R20 or 255/60R18, and the QX80 uses either 275/50R22 or 275/60R20. Every one of those sizes is radial, but the widths, profiles, and wheel diameters differ by model and wheel package.

That variation matters because a modern Infiniti SUV often has more than one factory-style tire path depending on trim and wheel design. If you are replacing a full set, confirm the exact size from the existing sidewall and compare it to the wheel diameter on the vehicle. If you are replacing one damaged tire, make sure the replacement matches the same size and service description already on the vehicle.

For 2025 Infiniti Trucks, the available sidewall styles currently center on the shared 255/45R20 size used by the QX50 and QX55. That size is available with both Blackwall and RWL sidewalls. The Blackwall look is the cleaner, more understated appearance most buyers expect on a contemporary luxury crossover, while RWL adds a sportier, more visual sidewall treatment.

Sidewall style does not change the basic fitment, but it can change how the vehicle presents itself. On 2025 Infiniti Trucks, a Blackwall usually suits an OEM-style appearance, while RWL tends to stand out more and can lean toward a performance-themed look. If visual correctness matters to you, compare the tire sidewall to the way your QX50 or QX55 is equipped and decide whether you want subtle or more expressive styling.

For 2025 Infiniti Trucks, the shared 255/45R20 size is available from BFGoodrich, Nitto, and Pro-Trac. Within that size, BFGoodrich appears in multiple performance-oriented radial choices, Nitto offers a modern radial option, and Pro-Trac brings an RWL alternative. Those brands cover the QX50 and QX55 when equipped with the 20-inch fitment.

Brand choice on a modern Infiniti SUV usually comes down to the type of driving experience and sidewall look you want, rather than a vintage-style authenticity question. If you have a QX50 or QX55 on 20-inch wheels, compare service description, sidewall style, and wheel-width compatibility before choosing. If you own a QX60 or QX80, start by confirming the exact size first, since those models use different fitments.

On the 2025 Infiniti Trucks 255/45R20 size, BFGoodrich g-Force Comp-2 A/S and Pro-Trac Street Pro III share radial construction and a W speed rating format, but they differ in presentation and published details. The BFGoodrich version uses a Blackwall sidewall and carries a 32-pound weight figure, while the Pro-Trac Street Pro III uses an RWL sidewall and carries a 31.97-pound weight figure. BFGoodrich also shows an 8.0 to 9.5-inch rim-width range on applicable products in this size.

That makes the comparison less about basic fitment and more about appearance and how closely you want to follow the service details shown for a given tire. A buyer who wants a cleaner modern look may prefer Blackwall, while someone who likes a more assertive sidewall may lean toward RWL. Before choosing either one for a 2025 Infiniti Trucks QX50 or QX55, verify your wheel width and the complete sidewall marking on the tire you intend to run.

Rim-width guidance is available for the 2025 Infiniti Trucks 255/45R20 size, where applicable products cover an 8.0 to 9.5-inch wheel width range. That size fits the QX50 and QX55 when equipped with 20-inch wheels. The other 2025 Infiniti Trucks sizes still require matching to their correct wheel diameters, but the most specific rim-width range here belongs to the 255/45R20 fitment.

Wheel width matters because a tire can share the correct diameter yet still be wrong for the wheel if the width falls outside the approved range for the product you choose. On a 2025 Infiniti Trucks QX50 or QX55, use the actual wheel specification on the vehicle as your check point before selecting among 255/45R20 options. If you are unsure, confirm the wheel's stamped or manufacturer-published width rather than guessing from appearance.

2025 Infiniti Trucks tires in the available 255/45R20 products are modern radial tubeless designs. The sidewall markings shown for those products do not use tube-type designations, and the service descriptions follow contemporary tubeless passenger and SUV tire convention. That makes inner tubes unnecessary for normal use on the correct wheel.

The practical concern on a 2025 Infiniti Trucks vehicle is wheel condition and valve-stem condition rather than tube selection. If a wheel has been damaged, repaired, or refinished, make sure the bead seats and valve area are in proper shape before mounting a replacement tire. For any model and size, the safest path is to match the tire to the correct wheel diameter and use the mounting method intended by the tire manufacturer.

A 2025 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 sources. Even modern radial tires age faster when exposed to heat, UV, and long static periods on rough or contaminated surfaces. If the vehicle will sit for an extended time, rolling it periodically helps reduce prolonged stress in one contact patch area.

Collectors and seasonal drivers often focus on paint and battery maintenance, but tire care matters just as much on a luxury SUV that may spend long stretches parked. Keep the vehicle on a clean concrete or barrier mat, avoid petroleum contamination, and inspect the sidewalls when bringing it back into use. If storage will be especially long, some owners use stands to reduce load, but the suspension and storage plan should be considered as a whole.

Tires on a 2025 Infiniti Trucks vehicle should be judged by age as much as by tread depth. A good collector and specialty-use rule is to begin closer inspection once tires reach about five to seven years of service and to treat around ten years as a serious replacement consideration, even if the tread still looks strong. The DOT date code on the sidewall tells you when each tire was manufactured.

That timeline matters because many luxury SUVs accumulate low annual mileage, which can make an older tire appear healthier than it really is. Rubber hardens and internal materials age whether the vehicle is driven often or not. If your 2025 Infiniti Trucks model is used for family trips, highway travel, or longer seasonal drives, age-based replacement planning is more useful than waiting until the tread looks worn out.

Tires on a 2025 Infiniti Trucks vehicle deserve a quick inspection before every drive and a more deliberate inspection before any longer highway outing. Look for sidewall cracking, cuts, bulges, uneven wear, embedded debris, and signs that the tire is losing pressure. Because these are modern radial SUV tires, pressure condition and shoulder wear are especially important clues to catch early.

A brief walk-around can prevent a small issue from becoming a ruined trip or a damaged wheel. If the vehicle has been parked for a while, check all four tires plus the spare before heading out. Any repeated pressure loss, vibration, or uneven wear on a 2025 Infiniti Trucks model is a signal to inspect alignment, wheel condition, and suspension health rather than replacing tires blindly.

2025 Infiniti Trucks tires are modern radial designs, and the available 255/45R20 products carry W speed ratings, which correspond to a 168 mph ceiling under the tire manufacturer's rating conditions. That is far beyond normal U.S. highway speeds and well above what most drivers will ever approach in real road use. On a contemporary Infiniti crossover or SUV, the vehicle's weight, alignment, brakes, suspension condition, and tire age often matter more in everyday safety than the tire's ultimate speed symbol.

Highway safety still depends on using the correct size, keeping the tires properly inflated, and avoiding operation on aged or damaged rubber. A 2025 Infiniti Trucks QX50 or QX55 with 255/45R20 tires should use matching tires across the axle and preferably across the full set unless the manufacturer permits otherwise. Before any higher-speed travel, inspect pressure, tread condition, and any prior curb or pothole damage to the wheel and tire.

Inflation pressure for 2025 Infiniti Trucks tires should follow the vehicle placard or owner's manual first, because factory pressure targets are tuned to the specific model, wheel package, and load condition. In the available 255/45R20 products, one BFGoodrich option shows a maximum load of 1,819 pounds at 51 psi, but that figure is the tire's rated maximum rather than a universal operating recommendation for every 2025 Infiniti Trucks application.

Treat the tire's sidewall pressure figure as a load-rating reference, not an across-the-board fill target. A QX50 or QX55 may require a different day-to-day pressure than another Infiniti model using a different size, and a QX60 or QX80 should never borrow inflation assumptions from a separate fitment. For the best result, start with the placard setting, then monitor wear and ride quality while staying within the tire manufacturer's limits.

Before taking a 2025 Infiniti Trucks vehicle on a longer drive, inspect each tire for visible cracking, punctures, tread damage, sidewall bulges, and irregular wear. Confirm cold inflation pressure, check that the valve stems are in good condition, and make sure the spare is present and serviceable if the vehicle is equipped with one. On modern Infiniti SUVs, wheel damage from potholes or curb contact is also worth checking closely.

Tires are only one part of a proper pre-trip inspection, but they are the part in constant contact with the road. If your 2025 Infiniti Trucks model has been parked for a while, include a short test drive to feel for vibration, pull, or flat-spotting before committing to a long run. It is also wise to look over brakes, fluid levels, lights, and wiper condition so the entire vehicle is ready for the trip.
