The 2007 Infiniti Trucks FX35 sits in the early wave of performance-oriented luxury crossovers, blending sport-sedan attitude with SUV ride height and a distinctly aggressive design. Buyers tend to value these vehicles for their sharp road manners and modern stance, which makes tire selection especially important to both appearance and everyday drivability. The 2007 Infiniti Trucks FX35 uses radial tires in two primary sizes, 265/60R18 and 265/50R20, so the first step is confirming which wheel diameter is actually on the vehicle. From there, the decision shifts to choosing the right metric radial fitment for the wheel setup, driving use, and any changes made since new.
Which Tire Size Is Right for The 2007 Infiniti Trucks FX35
The 2007 Infiniti Trucks FX35 uses two primary tire sizes, and both are radial fitments tied to different wheel diameters. Because both AWD and RWD versions can use either 265/60R18 or 265/50R20, the first thing to verify is whether the vehicle is wearing 18-inch or 20-inch wheels 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 designates radial construction, and 20 is the wheel diameter in inches. On the 2007 Infiniti Trucks FX35, this size supports the larger-wheel fitment and maintains the vehicle’s sport-oriented tire profile. Its overall diameter remains close to the 18-inch alternative, so the visual difference comes more from wheel and sidewall proportion than from a dramatic height change. This is the size to evaluate when the FX35 already has 20-inch wheels and you want to preserve that setup.
265/60R18 is a metric radial size where 265 is the nominal section width in millimeters, 60 is the aspect ratio, R indicates radial construction, and 18 is the wheel diameter in inches. For the 2007 Infiniti Trucks FX35, this size serves the 18-inch wheel fitment while keeping nearly the same overall tire diameter as the 20-inch option. That means the main distinction is wheel diameter and sidewall height rather than a major change in tire height. This size makes sense when the vehicle is equipped with 18-inch wheels and you want to stay with the proper radial fitment for that wheel.
Tire fitment is straightforward across the covered 2007 Infiniti Trucks FX35 sub-models because both AWD and RWD versions use the same two tire sizes. The key check is not drivetrain, but whether the vehicle has 18-inch or 20-inch wheels installed.

2007 Infiniti Trucks FX35 (AWD)
The 2007 Infiniti Trucks FX35 (AWD) uses the same two radial tire sizes found across this model range, so wheel diameter is the real fitment divider. Tire selection comes down to confirming whether the AWD vehicle is on 18-inch or 20-inch wheels, then choosing the correct metric radial size for that setup.
The 2007 Infiniti Trucks FX35 (RWD) also uses both primary radial tire sizes, making wheel size the important detail to confirm before replacement. Once the 18-inch or 20-inch wheel setup is verified, the correct tire choice follows the matching metric radial size rather than the drivetrain layout.
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
Tire questions for the 2007 Infiniti Trucks FX35 usually center on the two metric radial sizes, 18-inch versus 20-inch wheel fitment, and what to inspect before replacing tires on a used or modified crossover.
Tire Size & Fitment
What tire size fits a 2007 Infiniti Trucks FX35?
The 2007 Infiniti Trucks FX35 uses two primary tire sizes: 265/60R18 and 265/50R20. Both are radial metric sizes, and both appear on this model in AWD and RWD form, so the correct choice depends on the wheel diameter actually installed on the vehicle.
That makes wheel confirmation more important than drivetrain when replacing tires. Check the existing sidewall markings and verify the wheel itself before ordering, especially if the FX35 has changed hands or has aftermarket wheels. The two sizes are close in overall diameter, but each is intended for a different rim diameter.
What size rim does a 2007 Infiniti Trucks FX35 use?
A 2007 Infiniti Trucks FX35 uses either an 18-inch or 20-inch rim, depending on which of the two primary tire sizes is on the vehicle. The 265/60R18 tire pairs with an 18-inch wheel, while the 265/50R20 tire pairs with a 20-inch wheel.
The easiest mistake on this vehicle is assuming all FX35 models use the same wheel diameter. Before choosing tires, confirm the actual wheel size on the vehicle rather than relying only on trim assumptions. That is especially important on used examples, since wheels may have been swapped while keeping a similar overall tire height.
Do all 2007 Infiniti Trucks FX35 sub-models use the same tire size?
AWD and RWD versions of the 2007 Infiniti Trucks FX35 share the same two tire sizes, 265/60R18 and 265/50R20. The fitment difference is tied to wheel diameter, not to a separate tire size reserved for one drivetrain and not the other.
That means identifying the exact sub-model helps less than confirming the actual wheel setup on the vehicle. An AWD FX35 can be on 18-inch or 20-inch wheels, and the same is true for RWD. Sidewall size markings, wheel measurements, and clearance checks are the practical steps before selecting replacement tires.
Choosing the Right Tire
What should I consider when choosing a 265/50R20 tire for a 2007 Infiniti Trucks FX35?
Start by confirming that the vehicle actually has 20-inch wheels, since 265/50R20 is the larger-wheel fitment for the 2007 Infiniti Trucks FX35. This size uses a 265-millimeter section width with a lower-profile 50-series sidewall, so it preserves the intended relationship between the tire and a 20-inch rim.
Selection should focus on staying with the correct size and matching the tire to how the FX35 is driven. Look closely at wheel condition, suspension wear, and any signs of rubbing before replacement. On vehicles with non-original wheels, verify that the rim diameter and overall package still support the proper 265/50R20 fitment.
What should I consider when choosing a 265/60R18 tire for a 2007 Infiniti Trucks FX35?
The first consideration is confirming that the FX35 is equipped with 18-inch wheels, since 265/60R18 belongs on that rim diameter. This metric radial size uses the same nominal width as the 20-inch option, but with a taller 60-series sidewall to suit the 18-inch wheel.
Tire choice should center on correct sizing, wheel condition, and the vehicle’s actual setup rather than assuming every FX35 uses the same package. Check for wheel swaps, uneven wear, and alignment issues before installation. A used crossover can look stock while carrying changed wheels, so physical verification matters as much as the model year.
How do I choose between the available tire sizes for a 2007 Infiniti Trucks FX35?
You do not choose between 265/60R18 and 265/50R20 by preference alone; you choose the size that matches the wheel diameter already on the vehicle. Both are proper radial fitments for the 2007 Infiniti Trucks FX35, and both are used across AWD and RWD versions.
The practical comparison is between wheel setups rather than two interchangeable tire sizes. An 18-inch wheel requires 265/60R18, and a 20-inch wheel requires 265/50R20. If the FX35 has aftermarket wheels, confirm the actual wheel diameter and inspect for clearance at full steering lock before settling on a replacement tire.
Restoration & Appearance
Which tire should I choose for a period-style 2007 Infiniti Trucks FX35?
A period-style approach for a 2007 Infiniti Trucks FX35 starts with keeping the correct original-type metric radial size for the wheel diameter on the vehicle. That means using 265/60R18 on 18-inch wheels or 265/50R20 on 20-inch wheels, rather than treating the two sizes as interchangeable options.
Appearance on this generation depends heavily on preserving the right wheel-and-sidewall proportion. A replacement tire that matches the correct size helps the FX35 retain the stance and visual balance intended for its wheel package. On vehicles that have been modified, compare the current setup carefully before trying to return to a more stock-looking presentation.
Does correct tire fitment matter for a 2007 Infiniti Trucks FX35 restoration?
Correct tire fitment matters on a 2007 Infiniti Trucks FX35 because the vehicle was offered with two distinct wheel-and-tire packages. Using the proper 265/60R18 or 265/50R20 size keeps the wheel diameter and sidewall relationship aligned with the setup the vehicle is meant to carry.
That is important not only for appearance, but also for maintaining sensible clearance and overall proportions. A restoration-minded owner should verify the actual wheels on the vehicle and compare them with any prior changes before replacing tires. If exact originality matters, marque-specific records and original vehicle documentation are still the best references.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2007 Infiniti Trucks FX35?
Yes, modifications can affect tire fitment on a 2007 Infiniti Trucks FX35 even when the sidewall size looks familiar. Aftermarket wheels, altered offsets, suspension changes, lowering, or body modifications can all change how a 265/60R18 or 265/50R20 tire sits in the wheel opening and how much clearance remains.
That is why a size that belongs on the model generally still needs to be checked against the specific vehicle. Inspect steering clearance, inner-fender space, and suspension travel before replacement. A used FX35 may have changes that are not obvious at first glance, so measuring the installed setup is smarter than relying on appearance alone.
What should I inspect before driving a 2007 Infiniti Trucks FX35 on new tires?
Before driving a 2007 Infiniti Trucks FX35 on new tires, inspect the wheels for damage, confirm the correct size, and make sure the tires were mounted on the proper rim diameter. It is also wise to check alignment, valve stems, and whether the old tires showed uneven wear that could point to suspension or steering issues.
A road-ready check should also include tire pressure, lug torque, and clearance at full lock from side to side. Watch for rubbing, vibration, or a pull during the first miles. Any collector or low-use vehicle deserves extra attention to aged bushings and components, since fresh tires can reveal problems the previous set masked.
How often should tires on a 2007 Infiniti Trucks FX35 be inspected?
Tires on a 2007 Infiniti Trucks FX35 should be inspected regularly, not just when tread looks low. Monthly pressure checks are a good habit, and visual inspections should look for cracking, bulges, punctures, irregular wear, and signs that the tire is contacting suspension or body parts it should clear.
Inspection becomes even more important if the vehicle is driven infrequently or sits for long periods. A crossover that appears to have usable tread can still have age-related condition issues. Checking the tires before longer trips, after seasonal storage, and after any wheel or suspension work helps catch problems before they become roadside surprises.
