The 2012 Infiniti Trucks FX35 blends luxury-crossover styling with the athletic stance that helped the FX line stand apart from more conventional SUVs of its era. Its long-hood proportions and performance-oriented character make wheel and tire fitment a visible part of the vehicle’s personality, not just a maintenance item. For this exact model, tire selection centers on three radial sizes: 265/60R18, 265/50R20, and 265/45R21, with fitment depending on the specific sub-model and wheel setup. That means the real choice is less about vintage construction and more about confirming the correct rim diameter, preserving the intended look, and matching the tire size to the FX35’s actual configuration.
Which Tire Size Is Right for The 2012 Infiniti Trucks FX35
The 2012 Infiniti Trucks FX35 uses three primary tire sizes, and the right one depends on the exact sub-model and wheel diameter on the vehicle. All three fitments are radial, but they are tied to different 18-inch, 20-inch, and 21-inch wheel setups, so confirming the actual rim diameter is the first step before comparing tire options or replacing a worn set.
A 265/50R20 tire uses a 265-millimeter section width, a 50-series aspect ratio, radial construction, and a 20-inch rim. On the 2012 Infiniti Trucks FX35, this size supports the model’s sport-luxury character with a modern low-profile radial format rather than an older bias-ply sizing system. It is closely related in overall diameter to the other FX35 fitments, but it is still tied to a specific wheel diameter. This size is the right one to evaluate when the vehicle is equipped with 20-inch wheels and you want to keep the intended balance of appearance and fitment.
A 265/60R18 tire keeps the same 265-millimeter section width as the other FX35 sizes, but pairs it with a taller 60-series profile on an 18-inch rim. That makes it a modern metric radial size with a little more sidewall presence than the 20-inch and 21-inch alternatives used on this model. It belongs to a different wheel setup, even though the overall diameter stays very close to the other primary fitments. This is the size to confirm when the FX35 has 18-inch wheels and you want replacement tires that match that original wheel diameter.
A 265/45R21 tire combines a 265-millimeter section width with a shorter 45-series profile and a 21-inch rim diameter. On the 2012 Infiniti Trucks FX35, this radial size reflects the largest wheel package used among the primary fitments, giving the vehicle a distinctly more aggressive wheel-and-tire presentation. Even with its lower profile, its overall diameter remains close to the other FX35 sizes, but the 21-inch wheel requirement makes it a separate fitment path. This size should be chosen only after confirming the vehicle is equipped with the matching 21-inch wheel setup.
Tire fitment for the 2012 Infiniti Trucks FX35 varies by sub-model, so identifying the exact version matters before selecting a replacement. The main distinction is wheel diameter, with the Base model using two possible sizes and the Limited Edition using a separate 21-inch fitment.

2012 Infiniti Trucks FX35 Base
The 2012 Infiniti Trucks FX35 Base uses either 265/60R18 or 265/50R20 radial tires, depending on the wheel package installed on the vehicle. That makes wheel confirmation especially important, since the correct replacement decision starts with whether the FX35 is sitting on 18-inch or 20-inch rims.
The 2012 Infiniti Trucks FX35 Limited Edition uses a 265/45R21 radial tire, tying it to the model’s 21-inch wheel setup. Tire selection here is more straightforward than on the Base model, but the larger rim diameter still needs to be confirmed before ordering replacements or comparing tire choices.
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 tire sizes used on the 2012 Infiniti Trucks FX35, how sub-model and wheel diameter affect fitment, and what to check when choosing replacement tires for everyday driving or long-term ownership.
Tire Size & Fitment
What tire size fits a 2012 Infiniti Trucks FX35?
The 2012 Infiniti Trucks FX35 uses three primary radial tire sizes: 265/60R18, 265/50R20, and 265/45R21. The Base model uses either 265/60R18 or 265/50R20 depending on its wheel setup, while the Limited Edition uses 265/45R21.
The most important step is confirming the exact sub-model and the actual wheel diameter on the vehicle before replacing tires. These sizes stay close in overall diameter, but each one is built around a different rim size, so choosing by appearance alone can lead to the wrong fitment.
What size rim does a 2012 Infiniti Trucks FX35 use?
The 2012 Infiniti Trucks FX35 uses three rim diameters across its tire fitments: 18-inch, 20-inch, and 21-inch. The 265/60R18 tire fits an 18-inch rim, the 265/50R20 fits a 20-inch rim, and the 265/45R21 fits a 21-inch rim.
Rim diameter should be verified before looking at tread design or brand preferences, because a tire must match the wheel’s diameter exactly. Checking the sidewall marking on the current tire and confirming the wheel setup on the vehicle is the safest way to narrow the search to the correct FX35 fitment.
Do all 2012 Infiniti Trucks FX35 sub-models use the same tire size?
No. The 2012 Infiniti Trucks FX35 Base can use either 265/60R18 or 265/50R20, while the 2012 Infiniti Trucks FX35 Limited Edition uses 265/45R21. That means the model line does not share one universal tire size across every covered configuration.
Sub-model identification matters because the tire decision is tied directly to wheel diameter. A Base model with 18-inch wheels and a Limited Edition with 21-inch wheels are not shopping for the same replacement tire, even though all three FX35 sizes are modern radial fitments with very similar overall height.
Choosing the Right Tire
What should I consider when choosing a 265/50R20 tire for a 2012 Infiniti Trucks FX35?
Start by confirming that the vehicle actually uses the 265/50R20 size, since the 2012 Infiniti Trucks FX35 also appeared with 18-inch and 21-inch wheel packages. Once the size is confirmed, the main priorities are maintaining the correct 20-inch fitment, selecting a tire suited to the vehicle’s intended road use, and matching the look you want.
A sensible comparison includes sidewall profile, overall fit on the existing wheel, and how the tire complements the FX35’s sporty stance. It also helps to inspect the current wheels for damage and verify that no wheel, suspension, or body changes have altered clearance from the original setup.
What should I consider when choosing a 265/60R18 tire for a 2012 Infiniti Trucks FX35?
A 265/60R18 tire is one of the primary fitments for the 2012 Infiniti Trucks FX35 Base, so the first task is confirming that the vehicle is equipped with the 18-inch wheel package. From there, the choice centers on keeping the proper radial size and selecting a tire that suits the vehicle’s daily driving needs and overall presentation.
Because this size uses a taller sidewall than the FX35’s 20-inch and 21-inch alternatives, buyers often pay attention to how the tire fills the wheel opening and maintains the vehicle’s intended proportions. Wheel condition, alignment, and any non-stock suspension changes should be checked before settling on a replacement set.
How do I choose between the available tire sizes for a 2012 Infiniti Trucks FX35?
The correct choice is not a matter of preference alone, because the 2012 Infiniti Trucks FX35 uses different sizes for different wheel packages. The right tire is the one that matches the vehicle’s actual setup: 265/60R18 for an 18-inch wheel, 265/50R20 for a 20-inch wheel, or 265/45R21 for a 21-inch wheel.
After identifying the installed wheel diameter, compare replacement options within that exact size rather than jumping between the three primary fitments. It is also worth checking whether the FX35 still carries its original wheels, since previous owners sometimes change wheel packages and create a mismatch between trim level and current tire size.
Restoration & Appearance
Which tire should I choose for a period-style 2012 Infiniti Trucks FX35?
A period-style choice for a 2012 Infiniti Trucks FX35 starts with keeping the correct original fitment format and wheel diameter already on the vehicle. That means selecting the proper radial size for the actual setup, whether that is 265/60R18, 265/50R20, or 265/45R21, rather than treating the three sizes as interchangeable.
Because the FX35 is a modern luxury-performance crossover, its appearance is strongly influenced by wheel-and-tire proportion. Staying with the proper rim diameter and sidewall profile preserves the stance the vehicle was built around, while any move to a different wheel package should be evaluated carefully for appearance, clearance, and overall visual balance.
Does correct tire fitment matter for a 2012 Infiniti Trucks FX35 restoration or clean-preservation project?
Yes, correct tire fitment matters on a 2012 Infiniti Trucks FX35 because the model’s design relies heavily on the relationship between body shape, wheel diameter, and sidewall height. Using the proper 18-inch, 20-inch, or 21-inch tire size helps maintain the intended proportions and avoids an obviously mismatched look.
For an owner preserving the vehicle’s original character, confirming the exact wheel package is just as important as choosing a fresh tire. Even small-looking changes in profile can alter how the FX35 sits visually, so it is worth checking current wheels, verifying size markings, and keeping the fitment aligned with the vehicle’s present configuration.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2012 Infiniti Trucks FX35?
Yes. Modifications can change tire fitment on a 2012 Infiniti Trucks FX35, especially if the vehicle has aftermarket wheels, altered suspension height, wheel spacers, or body changes around the fenders. Even when the tire size matches one of the primary FX35 fitments, the actual clearance picture may no longer match a stock vehicle.
A modified setup should be checked for wheel diameter, wheel width, steering clearance, and space at full suspension movement before replacing tires. Looking at the current tire wear pattern can also help reveal alignment or clearance issues that should be corrected before a new set goes into service.
What should I inspect before driving a 2012 Infiniti Trucks FX35 on new tires?
Before driving a 2012 Infiniti Trucks FX35 on new tires, inspect the wheels for damage, confirm that all four tires are the correct size for the vehicle’s wheel package, and make sure inflation is set properly for the application. It is also smart to check valve stems, lug torque, and general tire seating after installation.
Road use is smoother when the rest of the chassis is in good condition, so a quick look at alignment, suspension wear, and any rubbing marks inside the wheel wells is worthwhile. A short test drive followed by another pressure and visual check can help catch issues early before normal use resumes.
What should I check before a longer drive in a 2012 Infiniti Trucks FX35?
Before a longer drive in a 2012 Infiniti Trucks FX35, check tire pressure, tread condition, and the sidewalls for cracks, bulges, cuts, or uneven wear. The vehicle should also be carrying the correct tire size for its actual wheel setup, whether that is 265/60R18, 265/50R20, or 265/45R21.
Longer trips put more heat and load into the tires, so it helps to confirm that the wheels are in sound condition and that the tires are not aging out from low-use storage. An owner should also listen for vibration, inspect for slow air loss, and make sure there is adequate clearance with the steering turned fully in both directions.
