The 2014 Infiniti Trucks QX60 sits in the early wave of three-row luxury crossovers that blended family usefulness with a more upscale road feel and styling. Buyers looking at one today are usually balancing daily-driver practicality with the need to keep ride quality, stance, and overall proportions consistent with the vehicle’s original character. Tire fitment centers on two radial sizes, 235/65R18 and 235/55R20, so the first step is confirming which wheel diameter is on the vehicle. Because both the Base and Hybrid can use either size, the real decision usually comes down to wheel setup, tire construction continuity, and how the finished look and ride suit the vehicle.
Which Tire Size Is Right for The 2014 Infiniti Trucks QX60
The 2014 Infiniti Trucks QX60 uses two primary tire sizes, and the difference comes down to wheel diameter rather than a change in basic tire construction. Both sizes are radial, but one fits an 18-inch rim and the other fits a 20-inch rim, so confirming the actual wheels on the vehicle is the most important first step before comparing tire choices.
The size code 235/55R20 identifies a metric radial tire with a 235-millimeter nominal section width, a 55-series aspect ratio, and fitment for a 20-inch wheel. On the 2014 Infiniti Trucks QX60, this size supports the larger wheel setup while keeping the overall tire height close to the alternate 18-inch fitment. The lower-profile sidewall gives this size a distinctly modern crossover appearance and a different visual balance than the 18-inch option. It is the right size to evaluate when the vehicle already has 20-inch wheels and you want to preserve that wheel-and-tire proportion.
The size code 235/65R18 indicates a metric radial tire with a 235-millimeter nominal section width, a 65-series aspect ratio, and an 18-inch rim fitment. For the 2014 Infiniti Trucks QX60, this size uses the smaller wheel diameter while maintaining nearly the same overall tire height as the 20-inch alternative. The taller sidewall changes the look of the vehicle slightly and can matter to buyers trying to match the current wheel package already in place. This is the size to consider when the QX60 is equipped with 18-inch wheels and the goal is to keep the fitment consistent.
Tire fitment is straightforward across the covered 2014 Infiniti Trucks QX60 sub-models because both the Base and Hybrid can use the same two radial sizes. That makes wheel diameter the key detail to verify before selecting tires, not the sub-model badge alone.

2014 Infiniti Trucks QX60 Base
The 2014 Infiniti Trucks QX60 Base can use either of the vehicle’s two primary radial tire sizes, so fitment depends on whether it has 18-inch or 20-inch wheels. Tire selection starts with confirming the installed wheel diameter and then choosing a size that matches the vehicle’s existing setup.
The 2014 Infiniti Trucks QX60 Hybrid follows the same tire-fitment pattern as the Base model, with both primary radial sizes applicable depending on wheel diameter. That means the practical choice is tied to the wheels on the vehicle rather than a separate Hybrid-only tire specification.
The tire sizes listed on this page assume factory-standard vehicle configuration. The following modifications may affect tire fitment and are not reflected in this guide:
Suspension changes (lowering, lift kits, spring replacements)
Body alterations (fender modifications, custom bodywork)
If your vehicle has been modified from factory specifications, verify tire clearance before purchase.
Frequently Asked Questions
These FAQs focus on the two radial tire sizes used on the 2014 Infiniti Trucks QX60, how wheel diameter affects fitment, and what to check when choosing tires for regular road use, appearance, and long-term vehicle upkeep.
Tire Size & Fitment
What tire size fits a 2014 Infiniti Trucks QX60?
The 2014 Infiniti Trucks QX60 uses two primary tire sizes: 235/65R18 and 235/55R20. Both are radial sizes, and both are used on this exact year and model, including the Base and Hybrid sub-models.
The key difference is wheel diameter, not sub-model alone. A QX60 with 18-inch wheels needs 235/65R18, while a QX60 with 20-inch wheels needs 235/55R20. Checking the tire sidewall already on the vehicle and confirming the actual wheel size is the safest starting point, especially if the vehicle has had wheels replaced at some point.
What size rim does a 2014 Infiniti Trucks QX60 use?
A 2014 Infiniti Trucks QX60 uses either an 18-inch rim or a 20-inch rim, depending on which of its two primary tire sizes is on the vehicle. The 235/65R18 size fits an 18-inch rim, and the 235/55R20 size fits a 20-inch rim.
That rim diameter difference is central to tire selection because the two sizes are not meant for the same wheel. Before ordering replacement tires, confirm the wheel diameter stamped on the wheel or match it to the size marked on the current tire. This matters even more on used QX60 models, where aftermarket wheels may have changed the original setup.
Do all 2014 Infiniti Trucks QX60 sub-models use the same tire size?
The 2014 Infiniti Trucks QX60 Base and 2014 Infiniti Trucks QX60 Hybrid share the same fitment pattern, but that does not mean every vehicle uses one single tire size. Both sub-models can use either 235/65R18 or 235/55R20, depending on the wheel package installed.
That makes the sub-model name less important than the actual wheel diameter on the vehicle in front of you. A Base model is not automatically 18-inch, and a Hybrid is not automatically 20-inch. The practical step is to inspect the existing tire size or measure the wheel before choosing replacement tires for either sub-model.
Choosing the Right Tire
What should I consider when choosing a tire for a 2014 Infiniti Trucks QX60?
Start with the correct primary size for the wheels on the vehicle: 235/65R18 for 18-inch rims or 235/55R20 for 20-inch rims. Since both sizes are radial and both apply to the 2014 Infiniti Trucks QX60, the first decision is matching the tire to the installed wheel diameter.
After that, compare factors such as overall tire appearance, how much sidewall you want to retain, and whether the vehicle is being kept in its current wheel configuration. It also helps to review load-related specifications and general fitment details so the replacement tire suits the QX60’s intended road use and the wheel setup already on the vehicle.
How do I choose between 235/65R18 and 235/55R20 tires for a 2014 Infiniti Trucks QX60?
The choice between 235/65R18 and 235/55R20 is not a matter of preference alone, because each size is tied to a different wheel diameter. The 235/65R18 size belongs on an 18-inch wheel, while 235/55R20 belongs on a 20-inch wheel.
Even though the two sizes have very similar overall diameters, they are not interchangeable on the same rim. The 18-inch setup uses a taller sidewall, and the 20-inch setup uses a shorter sidewall for a different visual balance. If the QX60 has had wheel changes, verify the current wheels first so the replacement tire matches the actual hardware on the vehicle.
What does 235/55R20 mean on a 2014 Infiniti Trucks QX60?
On a 2014 Infiniti Trucks QX60, 235/55R20 is a metric radial size. The 235 refers to nominal section width in millimeters, 55 is the aspect ratio, R indicates radial construction, and 20 is the wheel diameter in inches.
Understanding that code helps prevent a common mistake: choosing by width alone without matching the wheel diameter. The QX60 also uses 235/65R18, which has the same nominal width but fits a different rim and uses a taller sidewall. Reading the full size code on the current tire is the best way to confirm the correct replacement size.
Restoration & Appearance
Does correct tire fitment matter for a 2014 Infiniti Trucks QX60 restoration?
Yes, correct tire fitment still matters on a 2014 Infiniti Trucks QX60, even though it is a newer luxury crossover rather than a traditional antique or muscle-era vehicle. Using the proper primary size for the wheel diameter helps preserve the vehicle’s intended stance, wheel-to-tire proportion, and everyday drivability.
Appearance is part of that decision. A QX60 on 18-inch wheels with 235/65R18 tires presents differently than one on 20-inch wheels with 235/55R20 tires, even though overall diameter stays close. Anyone trying to return the vehicle to a more original-style presentation should confirm the wheel package first and avoid mixing sizes simply for convenience.
How does tire size affect the appearance of a 2014 Infiniti Trucks QX60?
Tire size changes the visual character of a 2014 Infiniti Trucks QX60 because the two primary fitments use different wheel diameters and sidewall proportions. The 235/65R18 size shows more sidewall, while the 235/55R20 size pairs with a larger wheel and a shorter sidewall look.
That difference may seem subtle on paper, but it matters when the goal is to keep the vehicle’s existing presentation consistent. Replacing tires in the same size already matched to the wheels usually preserves the look best. If the QX60 has been modified with different wheels, step back and confirm the overall stance and clearance before choosing a replacement tire size.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2014 Infiniti Trucks QX60?
Yes, modifications can affect tire fitment on a 2014 Infiniti Trucks QX60. Wheel changes, altered offsets, suspension lowering, or other ride-height changes can influence which tire size works properly, even when the vehicle originally used either 235/65R18 or 235/55R20.
A used QX60 may not still be on its original wheel package, so it is important to check the current setup rather than assume fitment by model year alone. Look at wheel diameter first, then inspect clearance at the strut, inner fender, and steering range. That extra step helps prevent selecting a tire that matches the badge but not the actual vehicle configuration.
What should I inspect before driving a 2014 Infiniti Trucks QX60 on new tires?
Before driving a 2014 Infiniti Trucks QX60 on new tires, confirm that the installed size matches the wheel diameter and that all four tires are seated properly. It is also worth checking tire pressure, valve condition, wheel fastener torque, and visible clearance around the suspension and fenders.
A short, careful initial drive can reveal rubbing, vibration, or steering issues before the vehicle goes back into normal use. After a brief run, inspect for any sign of contact and verify pressure again once the tires have settled. On a crossover that may carry passengers and cargo regularly, small fitment errors are worth catching early.
How often should tires on a 2014 Infiniti Trucks QX60 be inspected?
Tires on a 2014 Infiniti Trucks QX60 should be inspected regularly, not only when replacement is due. A quick visual check for uneven wear, cuts, bulges, cracking, and air loss should become part of routine ownership, especially on a vehicle that may alternate between daily use and longer idle periods.
More thorough inspection before a road trip is a smart habit. Pay attention to tread condition, sidewall health, and whether all four tires still match the intended wheel setup. Vehicles that sit for stretches can develop issues that are easy to miss at a glance, so periodic pressure checks and close visual inspections help keep the QX60 road-ready.
