Infiniti Trucks QX60 Tires

Infiniti Trucks QX60 uses four tire sizes across the 2014-2026 span. Models from 2014 through 2020 use either 235/65R18 on 18-inch wheels or 235/55R20 on 20-inch wheels. Models from 2022 through 2025 use either 255/60R18 on 18-inch wheels or 255/50R20 on 20-inch wheels, while 2026 is listed with 255/50R20 only.

The practical takeaway is that year alone is not enough for most Infiniti Trucks QX60 fitment decisions. Start by confirming the model year group, then verify whether the vehicle carries 18-inch or 20-inch wheels, and finally match the tire size to that wheel diameter. That approach avoids the most common mistake, which is selecting the right year range but the wrong wheel package.

A 2014 Infiniti Trucks QX60 has two tire sizes listed because the model was offered with two different wheel diameters. The 18-inch package uses 235/65R18, while the 20-inch package uses 235/55R20. The same two-way split continues through the 2020 model year, and a similar 18-inch versus 20-inch split appears again from 2022 through 2025 with different size codes.

That means the right answer depends on the specific wheel package on the vehicle in your garage, not just the badge on the liftgate. Check the tire sidewall currently on the vehicle, the wheel diameter itself, or the factory door-jamb information label. If the vehicle has had wheels changed at some point, use the actual wheel diameter on the car rather than assuming the original package is still in place.

Infiniti Trucks QX60 uses two rim diameters across the years covered here: 18 inches and 20 inches. The 18-inch fitments are 235/65R18 for 2014-2020 and 255/60R18 for 2022-2025. The 20-inch fitments are 235/55R20 for 2014-2020 and 255/50R20 for 2022-2026.

Wheel diameter is the first fitment check because every listed size is tied directly to either an 18-inch or 20-inch wheel. If the sidewall ends in R18, it belongs on an 18-inch rim; if it ends in R20, it belongs on a 20-inch rim. Never treat the two diameters as interchangeable, even when the overall vehicle model and year range seem close.

A 2023 Infiniti Trucks QX60 uses one of two sizes: 255/60R18 if it has 18-inch wheels, or 255/50R20 if it has 20-inch wheels. That year falls in the later production group, so it does not use the earlier 2014-2020 235-width sizes. The correct choice is determined by the wheel diameter installed on the vehicle.

The fastest confirmation method is to read the size molded into the current tire sidewall and make sure it matches the wheel diameter on the vehicle. If the tires are being replaced after a wheel swap or a previous owner changed packages, inspect the actual rim size rather than relying on memory or a general parts lookup. Using the later year group first and wheel diameter second will narrow the choice correctly.

No product brand listings are included here for Infiniti Trucks QX60. The fitment information centers on year ranges, size codes, and the split between 18-inch and 20-inch wheel packages. That means the key decision on this page is selecting the correct size before comparing brand-specific options elsewhere.

For a modern crossover like Infiniti Trucks QX60, brand selection comes after fitment is settled. Once you know whether the vehicle needs 235/65R18, 235/55R20, 255/60R18, or 255/50R20, you can compare construction, touring character, and intended road use within that exact size. Starting with brand before size often leads buyers into the wrong wheel-diameter category.

No separate tire series are identified here for Infiniti Trucks QX60. All listed fitments use modern metric radial sizing, and the important distinction is not an old-style series family but the combination of width, aspect ratio, and wheel diameter tied to each year group. In practical terms, the page separates early 235-width fitments from later 255-width fitments and 18-inch wheels from 20-inch wheels.

That means your first filter should be fitment structure rather than series name. Buyers comparing options for Infiniti Trucks QX60 should make sure the replacement preserves the intended relationship between section width, sidewall height, and rim diameter for the specific year group. Once that foundation is correct, it becomes much easier to evaluate ride character and appearance within the proper size.

An Infiniti Trucks QX60 should be stored on a clean, dry surface away from direct sunlight, ozone sources, and long periods of standing water. Tire pressure should be kept at the vehicle’s recommended setting during storage, because an underinflated modern radial can develop flat spotting and shoulder stress if it sits for long intervals. Clean tires and wheels before storage so brake dust and road salts do not remain on the rubber.

If the Infiniti Trucks QX60 will sit for an extended period, move it occasionally or place it on tire cradles to spread the load. A climate-stable garage helps preserve both the rubber and the finish on larger 20-inch wheel packages. Seasonal inspection before returning the vehicle to regular use is especially worthwhile on vehicles that alternate between long storage periods and family-road-trip duty.

Tires on an Infiniti Trucks QX60 should be inspected at least monthly and again before any longer highway trip. Look for pressure loss, uneven shoulder wear, punctures, sidewall cracking, and impact damage from curbs or potholes, especially on lower-profile 20-inch fitments such as 235/55R20 and 255/50R20. Regular inspection matters because a modern crossover can mask early tire problems until vibration, noise, or handling changes become noticeable.

A consistent inspection routine also helps catch wheel-package-specific issues. The 18-inch sizes carry more sidewall height, while the 20-inch sizes have less cushion and may show damage differently after road impacts. Checking tread depth across the full width of the tire can also reveal alignment issues before they shorten tire life or affect the composed ride Infiniti Trucks QX60 is known for.

Tires on an Infiniti Trucks QX60 should be replaced when they show age cracking, impact damage, belt irregularity, persistent air loss, or other structural issues even if the remaining tread still looks usable. Tread depth alone is not the whole story on a modern radial, especially on a vehicle that may carry family passengers and spend time at highway speeds. Replacement should also be considered when ride vibration or abnormal wear continues after inflation and alignment have been corrected.

Date coding and overall condition both matter, particularly on lower-use vehicles that age out before they wear out. Many collector-minded owners drive fewer miles than the average family crossover owner, which can make aging less obvious. A careful inspection by a qualified tire professional is the best way to judge whether the tire’s structure still matches the vehicle’s intended road use.

The listed Infiniti Trucks QX60 sizes are modern metric radial fitments intended for normal road use when the tire selected matches the correct year group and wheel diameter. Safety depends on choosing the correct 18-inch or 20-inch fitment, maintaining proper inflation, and making sure the tire is in sound condition. A 2014-2020 vehicle should stay within the 235-width size set listed for its wheel package, while 2022-2026 models use the later 255-width set.

Public-road use also depends on the condition of the vehicle beyond the tires. Before regular driving, inspect alignment, brakes, suspension, and wheel condition so the new tires are not being asked to compensate for unrelated problems. Infiniti Trucks QX60 is a highway-capable crossover, but that capability only holds when the full tire-and-wheel package is matched correctly and maintained consistently.

Before driving an Infiniti Trucks QX60, check tire pressure, visible tread and sidewall condition, and the size code on the vehicle to confirm it matches the wheel diameter actually installed. A quick walkaround should also include looking for cuts, bulges, embedded objects, and irregular wear patterns that could point to alignment or suspension problems. On vehicles with 20-inch wheels, curb damage and impact-related issues deserve especially close attention.

That short inspection is valuable because Infiniti Trucks QX60 spans two size families and two wheel diameters over the years, making prior-owner substitutions possible. If the vehicle recently changed hands, verify that all four tires match each other and match the wheel diameter front and rear. Catching a mismatch before driving is far easier than diagnosing vibration, clearance issues, or handling changes afterward.

An Infiniti Trucks QX60 is a modern crossover, so appropriate speed is determined by the exact tire fitted, its condition, the vehicle load, and road conditions rather than by vintage-vehicle limitations. The key point is that the tire must be the correct size for the vehicle’s year and wheel package, because an incorrect fitment can alter handling and stability at normal road speeds. Sound condition and correct inflation are just as important as the size code itself.

Even with the right size installed, collector-style caution is still wise on any older used vehicle or one that has sat for long periods. Bring the Infiniti Trucks QX60 up to speed gradually after storage and pay attention to vibration, pull, or steering changes. If anything feels off, stop and inspect before continuing, because modern road capability depends on the entire tire, wheel, and chassis package working together.
