The 2013 Infiniti Trucks JX35 arrived as a three-row luxury crossover aimed at families who wanted premium comfort without giving up everyday versatility. Its blend of smooth road manners, upscale appointments, and modern utility makes tire choice more about matching the vehicle’s actual wheel setup than chasing a vintage-style restoration look. The 2013 Infiniti Trucks JX35 uses radial tires in two primary sizes, 235/55R20 and 235/65R18, depending on which wheels are on the vehicle. That means the key decision is confirming whether your JX35 is riding on 20-inch or 18-inch rims, then comparing tire options within the correct size for ride quality, appearance, and intended use.
Which Tire Size Is Right for The 2013 Infiniti Trucks JX35
The 2013 Infiniti Trucks JX35 uses two primary tire sizes, and the difference comes down to wheel diameter rather than a change from bias-ply to radial construction. Both sizes are radial, but one fits an 18-inch rim and the other fits a 20-inch rim, so the first step is confirming which wheels are actually on the vehicle before choosing a tire.
235/55R20 is a modern metric radial size in which 235 identifies the nominal section width in millimeters, 55 is the aspect ratio, R designates radial construction, and 20 is the rim diameter in inches. On the 2013 Infiniti Trucks JX35, this size suits vehicles equipped with 20-inch wheels and reflects a contemporary crossover fitment rather than a vintage sizing system. The overall dimensions keep it closely aligned with the alternate 18-inch setup, but the wheel diameter is different. This is the size to evaluate when your JX35 already has 20-inch rims and you want to maintain the intended wheel-and-tire relationship.
235/65R18 is also a modern metric radial size, with 235 indicating nominal section width in millimeters, 65 identifying the aspect ratio, R marking radial construction, and 18 showing the rim diameter in inches. For the 2013 Infiniti Trucks JX35, this size belongs on vehicles using 18-inch wheels and offers a fitment path separate from the 20-inch arrangement. Its section width is comparable to the alternate size, but the tire and wheel combination is built around a different rim. This is the right size to consider when the vehicle remains on its 18-inch wheel setup and you want to keep fitment consistent.
Sub-model fitment is straightforward here because the covered 2013 Infiniti Trucks JX35 Base can use either of the two primary radial tire sizes. What matters most is identifying the actual wheel diameter on the vehicle, since tire selection changes between the 18-inch and 20-inch setups.

Frequently Asked Questions
Common questions for the 2013 Infiniti Trucks JX35 usually center on the two tire sizes, the difference between the 18-inch and 20-inch wheel setups, and what to inspect before putting the vehicle back into regular road use.
Tire Size & Fitment
What tire size fits a 2013 Infiniti Trucks JX35?
The 2013 Infiniti Trucks JX35 uses two primary tire sizes: 235/55R20 and 235/65R18. Both are radial fitments, and each size corresponds to a different wheel diameter rather than a different tire construction style.
The important next step is checking which wheels are actually on the vehicle. A JX35 equipped with 20-inch rims needs 235/55R20, while one on 18-inch rims needs 235/65R18. Because both sizes have similar overall dimensions, some owners may assume they interchange freely, but the rim diameter must match the tire exactly.
What size rim does a 2013 Infiniti Trucks JX35 use?
A 2013 Infiniti Trucks JX35 can use either an 18-inch rim or a 20-inch rim, depending on the wheel setup. The 235/65R18 tire fits the 18-inch rim, and the 235/55R20 tire fits the 20-inch rim.
Verifying wheel diameter before shopping for tires prevents one of the most common fitment mistakes on modern crossovers with multiple factory-style wheel options. Checking the sidewall marking on the current tires is helpful, but confirming the actual wheel size on the vehicle is better, especially if wheels have been changed since new.
Why does the 2013 Infiniti Trucks JX35 have more than one tire size?
The 2013 Infiniti Trucks JX35 has more than one tire size because it can be equipped with different wheel diameters. One fitment uses 235/65R18 on an 18-inch rim, while the other uses 235/55R20 on a 20-inch rim.
That difference does not mean one size is automatically an upgrade or that both can be used on the same wheel. It simply reflects two wheel-and-tire packages built around different rim diameters. Choosing correctly comes down to matching the tire to the wheel already on the vehicle and checking that any replacement keeps the setup consistent.
Choosing the Right Tire
What should I consider when choosing a tire for a 2013 Infiniti Trucks JX35?
Start with the correct size for the wheel on the vehicle: 235/55R20 for 20-inch rims or 235/65R18 for 18-inch rims. Because both JX35 fitments are radial, the main decision is not construction type but choosing the correct wheel-specific size and a tire that matches how the vehicle is used.
After size, compare practical factors such as load capability, intended road use, and overall tire character. A JX35 used mainly for commuting and family travel may call for different priorities than one used for frequent highway trips. Wheel compatibility and clearance still deserve attention, especially if the vehicle has had aftermarket wheel changes.
How do I choose between the available 2013 Infiniti Trucks JX35 tire sizes?
You do not choose between 235/55R20 and 235/65R18 as interchangeable options on the same wheel. The correct size is determined by the rim diameter already on your 2013 Infiniti Trucks JX35, with 20-inch wheels requiring 235/55R20 and 18-inch wheels requiring 235/65R18.
That means the decision is really about confirming the current wheel setup first. Once the rim diameter is established, compare tires within that one size instead of cross-shopping both sizes together. This keeps the selection process focused on proper fitment, ride expectations, and everyday use rather than treating two wheel packages as the same application.
What rim-fitment details matter when choosing 2013 Infiniti Trucks JX35 tires?
The most important rim-fitment detail is diameter. A 235/55R20 tire must go on a 20-inch rim, and a 235/65R18 tire must go on an 18-inch rim, so the tire size has to match the wheel exactly.
Wheel width and overall setup also matter, especially if the JX35 has non-original wheels. A replacement tire should be checked against the actual rim dimensions and the vehicle’s available clearance at full steering angle and suspension travel. That extra step is especially worthwhile on used vehicles where prior wheel changes are not always obvious at first glance.
Restoration & Appearance
Does correct tire fitment matter for a 2013 Infiniti Trucks JX35 restoration or refurbishment?
Yes, correct tire fitment matters because the 2013 Infiniti Trucks JX35 was built around two specific modern radial sizes tied to two specific wheel diameters. Using the proper 235/55R20 or 235/65R18 helps preserve the intended relationship between the wheel, tire, and overall stance.
For a careful refurbishment, appearance and fitment usually go together. A JX35 that retains its original-style wheel package should stay with the matching tire size for that wheel, while a vehicle with changed wheels should be checked closely before replacement. That approach keeps the finished look cohesive without making assumptions about what is currently on the vehicle.
How does tire size affect the appearance of a 2013 Infiniti Trucks JX35?
Tire size affects the appearance of a 2013 Infiniti Trucks JX35 because the two approved fitments are built around different wheel diameters. The 235/55R20 pairs with a larger 20-inch wheel, while the 235/65R18 pairs with an 18-inch wheel and a taller sidewall proportion.
That visual difference can change how the vehicle sits and how much tire sidewall is visible, even though the overall tire dimensions are fairly close. For an owner trying to keep the JX35 looking consistent with its intended wheel package, the right move is matching the replacement tire to the exact wheel diameter already on the vehicle.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2013 Infiniti Trucks JX35?
Yes, modifications can affect tire fitment on a 2013 Infiniti Trucks JX35. Aftermarket wheels, suspension changes, ride-height adjustments, or body alterations can all change the clearance relationship around either the 235/55R20 or 235/65R18 tire size.
A JX35 that has been lowered, fitted with different offsets, or switched to non-original wheels should be checked carefully before replacing tires. Steering clearance, fender clearance, and the actual wheel dimensions matter just as much as the tire size on the sidewall. That is why a visual and physical fitment check is worthwhile before installation.
What should I inspect before driving a 2013 Infiniti Trucks JX35 on new tires?
Before driving a 2013 Infiniti Trucks JX35 on new tires, inspect the wheels for damage, confirm the tire size matches the rim diameter, and look over suspension and steering components for looseness or wear. Proper inflation and secure mounting also deserve attention before regular road use.
A short test drive should be followed by another quick check for air loss, unusual rubbing, or vibration. That routine is especially helpful on a used JX35 where prior wheel changes or alignment issues may not be obvious right away. Catching those problems early helps protect the new tires and keeps the vehicle driving as intended.
How often should tires on a 2013 Infiniti Trucks JX35 be inspected?
Tires on a 2013 Infiniti Trucks JX35 should be inspected regularly, not just when replacement is overdue. A quick visual check for uneven wear, cuts, bulges, sidewall cracking, or persistent pressure loss can reveal developing issues before they turn into a larger fitment or safety problem.
That habit matters even more if the vehicle sees seasonal use or spends long periods parked. Tire age and condition can change faster than mileage suggests, especially when exposure to heat, sunlight, or long stationary periods is involved. Regular inspection also helps confirm that both tires on an axle remain matched in size and general condition.
