The 2008 Infiniti Trucks FX35 belongs to the first generation of Infiniti’s sporty crossover, a model known for blending SUV ride height with a sharper, more performance-oriented look than many utilities of its time. Its stance and proportions make tire choice especially important, because the wheel-and-tire package has a big effect on both appearance and road manners. For this exact FX35, the primary fitment centers on radial tires in either 265/50R20 or 265/60R18, depending on the wheel setup on the vehicle. That makes wheel diameter the first thing to confirm, followed by tire brand, tread style, and the overall look you want to preserve. A careful match keeps the FX35 looking right and driving as intended.
Which Tire Size Is Right for The 2008 Infiniti Trucks FX35
The 2008 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 size, the first step is confirming whether the vehicle is on 18-inch or 20-inch wheels before selecting a tire. Once that is settled, the decision shifts to choosing the right tire within the correct size for the vehicle’s appearance, intended use, and wheel setup.
A 265/50R20 tire uses a 265-millimeter nominal section width, a 50-series aspect ratio, radial construction, and a 20-inch rim. On the 2008 Infiniti Trucks FX35, this size supports the larger-diameter wheel setup and gives the vehicle the lower-profile look associated with a sport-oriented crossover. Because it is a modern metric radial format, buyers typically compare tires in this size by tread character, brand, and how well the tire suits the vehicle’s intended street use. This is the size to evaluate when the FX35 already has 20-inch wheels and you want to keep that wheel-and-tire presentation intact.
A 265/60R18 tire keeps the same 265-millimeter nominal section width but uses a 60-series profile on an 18-inch rim. For the 2008 Infiniti Trucks FX35, this size corresponds to the 18-inch wheel setup rather than the 20-inch package, so wheel diameter confirmation is essential before moving forward. The metric radial format is familiar to modern buyers and makes it easier to compare replacement tires based on overall road use and preferred tire character. This size is the correct place to start when the vehicle is equipped with 18-inch wheels and you want to stay with that original wheel diameter.
Tire fitment is straightforward across the covered 2008 Infiniti Trucks FX35 sub-models because both AWD and RWD versions use the same two radial tire sizes. What matters most is confirming the actual wheel diameter on the vehicle, since either drivetrain can be fitted with 18-inch or 20-inch wheels.

2008 Infiniti Trucks FX35 (AWD)
The 2008 Infiniti Trucks FX35 (AWD) can use either 265/50R20 or 265/60R18, both in radial construction. Tire selection starts with verifying whether the vehicle is on 20-inch or 18-inch wheels, then choosing a replacement that suits the FX35’s road use and overall appearance.
The 2008 Infiniti Trucks FX35 (RWD) also uses either 265/50R20 or 265/60R18 radial tires. That means the key step is checking the wheel setup on the individual vehicle rather than assuming size by drivetrain alone, especially if the wheels have ever been changed.
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
Common questions for the 2008 Infiniti Trucks FX35 usually come down to identifying the correct tire size by wheel diameter, understanding the two metric radial fitments, and checking how wheel changes or aging components can affect real-world fitment.
Tire Size & Fitment
What tire size fits a 2008 Infiniti Trucks FX35?
The 2008 Infiniti Trucks FX35 uses two primary tire sizes: 265/50R20 and 265/60R18. Both are radial tires, and both sizes apply to this model depending on the wheel package installed on the vehicle.
The important distinction is not AWD versus RWD, because both drivetrains can use either size. The real first step is confirming whether the FX35 has 20-inch or 18-inch wheels, then selecting a tire in the matching size. If the vehicle has aftermarket wheels, that check becomes even more important before any replacement decision is made.
What size rim does a 2008 Infiniti Trucks FX35 use?
A 2008 Infiniti Trucks FX35 uses either an 18-inch rim with 265/60R18 tires or a 20-inch rim with 265/50R20 tires. Those are the two wheel diameters associated with the primary tire fitments for this model.
That means rim diameter should be verified directly on the vehicle before ordering tires. A tire sized for an 18-inch wheel cannot be mounted on a 20-inch wheel, even though both sizes share the same nominal section width. Checking the wheel itself is especially worthwhile when the vehicle has changed hands or may have had its wheels replaced.
Do all 2008 Infiniti Trucks FX35 sub-models use the same tire size?
AWD and RWD versions of the 2008 Infiniti Trucks FX35 share the same two tire-size possibilities: 265/50R20 and 265/60R18. The sub-model alone does not narrow the fitment to one size, because either drivetrain can be associated with either wheel diameter.
That makes the actual wheel setup more important than the drivetrain badge when choosing tires. Looking at the existing tire sidewall or measuring the wheel diameter will answer the question faster than assuming fitment by trim. Once the wheel size is confirmed, tire shopping becomes much more straightforward and avoids ordering the wrong rim diameter.
Choosing the Right Tire
What should I consider when choosing a 265/50R20 tire for a 2008 Infiniti Trucks FX35?
Start by confirming that the vehicle is actually equipped with 20-inch wheels, because 265/50R20 is tied to that larger wheel diameter on the 2008 Infiniti Trucks FX35. This size uses modern metric radial construction and suits the FX35’s larger-wheel setup.
After size confirmation, compare tires based on the kind of driving the vehicle sees and the look you want to maintain. A replacement tire should match the wheel diameter, suit the FX35’s street use, and leave proper clearance in the current setup. Any suspension changes or wheel replacements should be checked before finalizing a tire in this size.
What should I consider when choosing a 265/60R18 tire for a 2008 Infiniti Trucks FX35?
A 265/60R18 tire is the correct fitment for a 2008 Infiniti Trucks FX35 that is equipped with 18-inch wheels. It uses the same nominal 265-millimeter width as the 20-inch fitment, but it is built around a different rim diameter and profile.
The main consideration is keeping the tire matched to the actual wheel size on the vehicle. From there, look at how the FX35 is used, how the tire complements the vehicle’s stance, and whether the wheel setup is still stock. Checking clearance and overall wheel condition is wise before installing any new set of tires.
How do I choose between the available tire sizes for a 2008 Infiniti Trucks FX35?
The choice between 265/50R20 and 265/60R18 is determined by the wheel diameter on the vehicle, not by personal preference alone. A 2008 Infiniti Trucks FX35 with 20-inch wheels needs the 20-inch fitment, while one with 18-inch wheels needs the 18-inch fitment.
Because both AWD and RWD versions can use either size, the smartest approach is to inspect the current wheel-and-tire package first. The sidewall on the existing tire usually confirms the size quickly. If the FX35 has been modified, verify wheel diameter, clearance, and overall setup before replacing tires so the new set matches the vehicle correctly.
Restoration & Appearance
Does correct tire fitment matter for a 2008 Infiniti Trucks FX35 restoration?
Yes, correct tire fitment matters on a 2008 Infiniti Trucks FX35 because the vehicle’s appearance depends heavily on the relationship between wheel diameter, tire profile, and body proportions. Using 265/50R20 or 265/60R18 keeps the tire matched to one of the proper primary fitment paths for this model.
For a restoration-minded owner, the first goal is preserving the right overall presentation for the wheel package actually on the vehicle. A mismatched rim diameter or an improvised substitute can change the FX35’s stance and visual balance. When originality matters closely, compare the current setup with vehicle records, original literature, or marque-specific references.
Which tire size should I choose for a period-style 2008 Infiniti Trucks FX35?
A period-style 2008 Infiniti Trucks FX35 should stay with one of its correct primary tire sizes: 265/50R20 or 265/60R18, depending on whether the vehicle is equipped with 20-inch or 18-inch wheels. Both sizes are modern metric radial fitments appropriate to the model’s era.
The right choice comes down to matching the tire to the wheel package that gives the vehicle its intended appearance. The 20-inch setup and the 18-inch setup create different visual impressions, so wheel confirmation comes first. If the goal is a more authentic presentation, avoid choosing by looks alone and verify the existing wheel arrangement before replacing tires.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2008 Infiniti Trucks FX35?
Yes, modifications can affect tire fitment on a 2008 Infiniti Trucks FX35 even when the tire size appears close to stock. Wheel changes, altered offsets, suspension modifications, or ride-height changes can all influence how a 265/50R20 or 265/60R18 tire sits in the wheel opening.
That is why a modified FX35 should be checked for steering clearance, fender clearance, and wheel compatibility before replacing tires. The same size can behave differently on a changed setup than it would on a stock vehicle. Looking closely at the current wheel package helps prevent rubbing, mounting issues, or an unintended change in stance.
What should I inspect before driving a 2008 Infiniti Trucks FX35 on new tires?
Before driving a 2008 Infiniti Trucks FX35 on new tires, inspect the wheels for damage, confirm that the tire size matches the wheel diameter, and make sure the tires are mounted and inflated properly. It is also wise to look over the suspension and steering components for visible wear.
A fresh set of tires performs best when the surrounding hardware is in good condition. Uneven wear, vibration, or a pull in the steering can point to alignment or component issues that should be addressed early. A short visual check for cuts, bulges, air loss, and any sign of interference in the wheel wells adds useful peace of mind.
How often should tires on a 2008 Infiniti Trucks FX35 be inspected?
Tires on a 2008 Infiniti Trucks FX35 should be inspected regularly rather than only when replacement is due. A routine walk-around can catch uneven wear, cracking, punctures, bulges, or low pressure before those issues turn into larger problems on the road.
Regular inspection matters even more on vehicles that are driven inconsistently or spend time parked. Tire condition can decline with age and environment as well as mileage, so tread alone does not tell the whole story. Checking pressure, sidewalls, and general condition before longer drives is a sound habit for keeping the FX35 ready for use.
