The 2011 Infiniti Trucks FX35 blends luxury-crossover refinement with the sharper stance and road-focused character that made the FX line stand out in its era. Its styling and chassis tuning gave it a more performance-oriented feel than many midsize SUVs, so tire choice has a real effect on both appearance and everyday driving manners. For this exact vehicle, the key fitment question is wheel diameter, because the FX35 Base uses either 265/50R20 or 265/60R18 radial tires. Both are modern metric radial sizes, but they serve different wheel setups. Before choosing, confirm which wheels are on the vehicle and whether it remains stock or has been modified.
Which Tire Size Is Right for The 2011 Infiniti Trucks FX35
The 2011 Infiniti Trucks FX35 uses two primary tire sizes, and the difference comes down to wheel diameter rather than tire construction. Both fitments are radial, but one is built for an 18-inch wheel and the other for a 20-inch wheel, so the first step is confirming which wheel package is actually on the vehicle before comparing tire choices.
265/50R20 is a metric radial size in which 265 identifies the nominal section width in millimeters, 50 is the aspect ratio, R denotes radial construction, and 20 is the wheel diameter in inches. On the 2011 Infiniti Trucks FX35, this size belongs to the 20-inch wheel setup and preserves the intended relationship between tire height and wheel diameter. Buyers considering this size should focus on matching it to the actual wheel on the vehicle and checking clearance carefully if the FX35 has aftermarket wheels, altered suspension, or other changes from stock.
265/60R18 is also a metric radial size, with a 265-millimeter nominal section width, a 60-series aspect ratio, radial construction, and an 18-inch rim diameter. For the 2011 Infiniti Trucks FX35, this size serves the 18-inch wheel package rather than the 20-inch setup. That makes wheel confirmation the deciding factor before purchase, especially on a used vehicle where wheel swaps are common. Owners aiming to keep the FX35 close to its intended fitment should verify both the wheel diameter and the current tire size already mounted on the vehicle.
Fitment is straightforward here because the covered sub-model shares the same two radial tire sizes used across this page. The important step is not trim identification so much as confirming whether the vehicle is wearing its 18-inch or 20-inch wheel setup.

Frequently Asked Questions
Owners of a 2011 Infiniti Trucks FX35 usually need to sort out exact tire size, wheel diameter, and the effect of modifications before replacing tires. These FAQs focus on fitment, radial tire selection, appearance, and the basic checks worth making before regular road use.
Tire Size & Fitment
What tire size fits a 2011 Infiniti Trucks FX35?
The 2011 Infiniti Trucks FX35 uses either 265/50R20 or 265/60R18. Both are radial tire sizes, and both apply to the FX35 Base depending on which wheel package is on the vehicle.
That means the first step is confirming the actual wheel diameter rather than choosing between different constructions. A used FX35 may no longer have its original wheels, so checking the current tire sidewall and measuring the wheel before replacement helps avoid ordering the right tire size for the wrong wheel.
What size rim does a 2011 Infiniti Trucks FX35 use?
The 2011 Infiniti Trucks FX35 uses either an 18-inch rim with 265/60R18 tires or a 20-inch rim with 265/50R20 tires. Both fitments are part of this model's tire range, so wheel diameter is the key fitment checkpoint.
Rim size should be verified on the vehicle itself before selecting tires, especially if the FX35 has changed hands or has aftermarket wheels. Tire size, wheel diameter, and overall clearance need to work together, and a 20-inch tire cannot be mounted on an 18-inch wheel or the other way around.
Why does the 2011 Infiniti Trucks FX35 have more than one tire size?
The 2011 Infiniti Trucks FX35 has more than one tire size because it was fitted with more than one wheel diameter. The two primary fitments are 265/60R18 for 18-inch wheels and 265/50R20 for 20-inch wheels, both in radial construction.
This is not a case of one size replacing the other at random; each one belongs to a specific wheel setup. The practical takeaway is simple: identify the wheels on the vehicle first, then match the tire size to that setup and check for any non-stock suspension or wheel changes before replacement.
Choosing the Right Tire
What should I consider when choosing a tire for a 2011 Infiniti Trucks FX35?
Start with the correct size for the wheel package on the vehicle: 265/60R18 for 18-inch wheels or 265/50R20 for 20-inch wheels. Since both fitments are radial, the main decision is not construction type but choosing the correct size for the actual wheel and intended use.
From there, consider whether the FX35 is kept stock, how it is driven, and whether ride, appearance, or everyday road use matters most. It also helps to inspect wheel condition, verify the existing tire size, and make sure any replacement maintains proper clearance at full steering lock and suspension movement.
How do I choose between the available 2011 Infiniti Trucks FX35 tire sizes?
There is no need to choose between 265/50R20 and 265/60R18 based on preference alone, because each size belongs to a different wheel diameter. The correct choice is whichever size matches the wheels currently installed on the 2011 Infiniti Trucks FX35.
Selection becomes a wheel-fitment question rather than a styling decision. Checking the sidewall of the current tires, confirming the wheel diameter, and looking for any signs of previous wheel or suspension changes will point you to the proper size and help avoid mismatching tire and rim dimensions.
What rim-fitment details should I compare when choosing 2011 Infiniti Trucks FX35 tires?
The most important rim-fitment detail is wheel diameter, because the 2011 Infiniti Trucks FX35 uses either an 18-inch or 20-inch setup. The tire size must match that wheel exactly, so 265/60R18 belongs with 18-inch rims and 265/50R20 belongs with 20-inch rims.
Beyond diameter, it is smart to confirm the wheel itself is appropriate for the tire and that the vehicle still has enough clearance around suspension and bodywork. That matters most on FX35s with non-stock wheels, lowered suspension, or prior modifications that may have changed how the tire sits in the wheel opening.
Restoration & Appearance
Does correct tire fitment matter for a 2011 Infiniti Trucks FX35 restoration?
Yes, correct tire fitment matters because the 2011 Infiniti Trucks FX35 was built around specific 18-inch and 20-inch wheel-and-tire combinations. Staying with 265/60R18 or 265/50R20, depending on the wheel setup, helps preserve the vehicle's intended stance and fit within the wheel openings.
A restoration-oriented approach should start with confirming which wheels belong on the vehicle and whether they remain in place. For owners pursuing exact presentation, vehicle-specific references such as original sales materials, marque resources, or prior ownership records can help confirm whether the current wheel package matches the vehicle's earlier configuration.
How does tire size affect the appearance of a 2011 Infiniti Trucks FX35?
Tire size has a noticeable effect on the 2011 Infiniti Trucks FX35 because its two fitments pair with visibly different wheel diameters. A 265/60R18 presents the vehicle with an 18-inch wheel setup, while a 265/50R20 is tied to the larger 20-inch package.
That makes appearance closely tied to the wheel-and-tire combination already on the vehicle. Owners who want to maintain the FX35's established look should match the replacement tire to the installed wheels rather than mixing sizes, and they should confirm that aftermarket changes have not altered the proportions or clearance around the tire.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2011 Infiniti Trucks FX35?
Yes, modifications can affect tire fitment on a 2011 Infiniti Trucks FX35 even when the tire size itself is correct. Aftermarket wheels, changes in wheel offset, lowered suspension, or altered ride height can all change how a 265/50R20 or 265/60R18 sits within the wheel opening.
That is why a modified FX35 should be checked for fender, suspension, and steering clearance before replacement tires are chosen. Even with the proper size for the wheel diameter, a changed setup may behave differently than stock, so measuring the existing combination is safer than assuming every FX35 is configured the same way.
What should I inspect before driving a 2011 Infiniti Trucks FX35 on new tires?
Before driving a 2011 Infiniti Trucks FX35 on new tires, confirm that the tire size matches the wheel diameter, then inspect wheel condition, valve stems, and tire pressure. It is also smart to check for any visible rubbing points, uneven wear patterns, or suspension issues that could affect how the new tires wear.
A short, careful test drive can reveal steering interference, vibration, or clearance problems that are easier to address early. The FX35 should also be checked for proper alignment if the old tires showed irregular wear, since new tires can wear quickly when alignment or suspension condition is already off.
How often should tires on a 2011 Infiniti Trucks FX35 be inspected?
Tires on a 2011 Infiniti Trucks FX35 should be inspected regularly, not just when replacement time arrives. A routine visual check for cracking, cuts, bulges, punctures, uneven wear, and air loss is worthwhile, especially on a vehicle that may see mixed city and highway use.
Inspection is also important after impacts, wheel changes, or suspension work. Catching wear or clearance issues early helps protect both 265/50R20 and 265/60R18 fitments, and it gives you time to correct pressure, alignment, or wheel problems before they shorten tire life or affect how the FX35 drives.
