The 2018 Nissan Trucks Murano sits in the modern crossover class, blending everyday comfort with the Murano’s more upscale, design-focused character. For owners, the tire decision is less about vintage-era construction choices and more about matching the exact trim to the correct wheel and tire package. This Murano uses radial tires in either 235/65R18 or 235/55R20, depending on sub-model. That creates a meaningful difference in rim diameter, tire profile, and the overall look of the vehicle. Before choosing a replacement, the key step is confirming whether the Murano has the 18-inch or 20-inch setup and whether it still retains its original wheel package.
Which Tire Size Is Right for The 2018 Nissan Trucks Murano
The 2018 Nissan Trucks Murano uses two primary tire sizes, and the correct one depends on the specific sub-model and wheel package. Both are radial fitments, but they use different rim diameters, so the first step is confirming whether the vehicle is on 18-inch or 20-inch wheels. Once that is established, the decision shifts to choosing the right replacement tire within the proper size for ride character, appearance, and intended use.
A 235/55R20 tire uses a 235-millimeter section width, a 55-series aspect ratio, radial construction, and a 20-inch rim diameter. On the 2018 Nissan Trucks Murano, this size belongs to trims equipped with the larger wheel package, giving the vehicle a lower-profile look than the 18-inch fitment. The shorter sidewall changes the visual stance while keeping the tire in the modern metric radial format familiar to current replacement buyers. This is the size to evaluate when the Murano carries factory-style 20-inch wheels and the goal is preserving the proper overall fitment for that setup.
A 235/65R18 tire also measures 235 millimeters in section width, but its 65-series profile is taller and it mounts on an 18-inch rim. For the 2018 Nissan Trucks Murano, this size applies to trims using the 18-inch wheel package, so it should not be treated as interchangeable with the 20-inch setup. The added sidewall height gives it a different visual proportion and a different relationship to the wheel. This is the size to choose when the Murano remains on its 18-inch wheels and the aim is to stay with the correct trim-specific fitment.
Sub-model fitment matters on the 2018 Nissan Trucks Murano because tire size changes with the trim’s wheel package. The main distinction is between 18-inch and 20-inch applications, so identifying the exact sub-model helps narrow the correct tire before comparing replacement options.

2018 Nissan Trucks Murano Platinum
The 2018 Nissan Trucks Murano Platinum uses the 235/55R20 radial fitment tied to the 20-inch wheel setup. Tire selection for this trim starts with confirming that the vehicle still carries the correct wheel diameter before choosing a replacement in the same size.
The 2018 Nissan Trucks Murano S uses the 235/65R18 radial tire size. For this sub-model, the key is staying with the 18-inch fitment unless the vehicle has been changed to a different wheel package that requires a separate size check.
The 2018 Nissan Trucks Murano SL uses the 235/65R18 radial size. That keeps tire selection straightforward as long as the Murano still has its 18-inch wheels, after which the buyer can focus on replacement priorities such as road use, ride preference, and brand choice.
The 2018 Nissan Trucks Murano SL Midnight Edition uses the 235/55R20 radial fitment. That makes wheel confirmation especially important, since this trim follows the 20-inch setup and needs replacements matched to that rim diameter rather than the 18-inch Murano sizes.
The 2018 Nissan Trucks Murano SV uses the 235/65R18 radial tire size. Choosing tires for this trim is mainly a matter of confirming the Murano still wears its 18-inch wheel package and then selecting a tire that suits the vehicle’s normal road use.
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
Murano owners usually need to confirm the exact trim, the wheel diameter, and the correct radial size before replacing tires. The questions below focus on 18-inch versus 20-inch fitment, trim-specific sizing, selection factors, and road-use checks.
Tire Size & Fitment
What tire size fits a 2018 Nissan Trucks Murano?
The 2018 Nissan Trucks Murano uses either 235/65R18 or 235/55R20 tires, depending on sub-model. S, SL, and SV models use 235/65R18, while Platinum and SL Midnight Edition use 235/55R20. Both are radial tire sizes, but they are built for different wheel diameters and should be matched to the vehicle’s actual wheel setup.
The practical difference is that the Murano does not have one universal tire size across every trim. The safest starting point is checking the sub-model and then confirming the wheel diameter already on the vehicle, especially if wheels have ever been replaced. Once that is settled, replacement shopping becomes much more straightforward.
What size rim does a 2018 Nissan Trucks Murano use?
A 2018 Nissan Trucks Murano uses either an 18-inch or 20-inch rim, depending on trim. The 235/65R18 fitment mounts on an 18-inch wheel, while the 235/55R20 fitment mounts on a 20-inch wheel. That rim diameter difference is central to choosing the correct replacement tire for the vehicle.
Wheel diameter should be verified before any tire order, because an 18-inch tire cannot be mounted on a 20-inch wheel and vice versa. If the Murano has aftermarket wheels, the sub-model alone may not tell the whole story. A quick check of the tire sidewall and the wheel package on the vehicle prevents an easy fitment mistake.
Do all 2018 Nissan Trucks Murano sub-models use the same tire size?
No, the 2018 Nissan Trucks Murano uses two different tire sizes across its sub-model range. S, SL, and SV models use 235/65R18, while Platinum and SL Midnight Edition models use 235/55R20. Both are radial sizes, but they belong to different wheel diameters and trim-specific wheel packages.
That means trim identification matters before comparing tire choices. A Murano owner who assumes every 2018 model uses the same size can easily end up looking at the wrong diameter. Checking the sub-model is the first step, but it is still smart to confirm the current wheels and the sidewall markings on the vehicle itself.
Choosing the Right Tire
What should I consider when choosing a tire for a 2018 Nissan Trucks Murano?
Start with the correct size for the exact sub-model: 235/65R18 for S, SL, and SV, or 235/55R20 for Platinum and SL Midnight Edition. Both are modern radial fitments, so the main choice is not construction type but making sure the replacement matches the Murano’s wheel diameter and intended use.
After size is confirmed, compare the tire’s role in everyday driving, seasonal conditions, and ride expectations. It also helps to check whether the Murano still has its original wheel package or has been changed in the past. Choosing within the correct size is much easier than trying to solve a fitment mismatch later.
How do I choose between the available 2018 Nissan Trucks Murano tire sizes?
A buyer usually does not choose between 235/65R18 and 235/55R20 freely on a 2018 Nissan Trucks Murano, because each size belongs to a specific trim and wheel package. The real choice is identifying which setup the vehicle has now. Once that is known, the correct tire size follows naturally.
The 18-inch and 20-inch fitments are close in overall diameter, but they are not mounted to the same rim size. That makes wheel confirmation more important than comparing the size codes in the abstract. If the Murano has different wheels than it left the factory with, use the current wheel and tire markings as the guide.
Why does the 2018 Nissan Trucks Murano have more than one tire size?
The 2018 Nissan Trucks Murano has more than one tire size because different sub-models use different wheel packages. S, SL, and SV trims use an 18-inch setup with 235/65R18 tires, while Platinum and SL Midnight Edition trims use a 20-inch setup with 235/55R20 tires. Both remain radial fitments within the same model year.
This is common on modern crossovers where trim level affects wheel diameter and overall appearance. For the owner, the important point is that the Murano’s correct tire size is tied to the wheel package on the vehicle, not just the model name. That is why trim and wheel verification should come before price or brand comparisons.
Restoration & Appearance
Does correct tire fitment matter for a 2018 Nissan Trucks Murano restoration?
Yes, correct tire fitment still matters on a 2018 Nissan Trucks Murano, even though it is a newer vehicle than traditional collector cars. The right size keeps the vehicle aligned with its intended wheel package, whether that means 235/65R18 on 18-inch wheels or 235/55R20 on 20-inch wheels. Getting the size right also preserves the Murano’s proper visual balance.
A restoration-minded owner should focus first on matching the trim and wheel diameter already associated with the vehicle. Appearance can change noticeably when the wrong profile is installed, even if the tire seems close at a glance. For a clean, correct-looking result, verify the sub-model, wheel setup, and sidewall markings before replacement.
How does tire size affect the appearance of a 2018 Nissan Trucks Murano?
Tire size affects the appearance of a 2018 Nissan Trucks Murano because the two fitments pair the same section width with different wheel diameters and sidewall proportions. The 235/55R20 setup gives the Murano a larger-wheel, lower-profile look, while the 235/65R18 setup presents more sidewall around the wheel.
That difference matters if the goal is keeping the vehicle visually consistent with its trim level. A Murano on the wrong diameter can look out of proportion even before any driving issues are considered. Owners trying to maintain a clean, original-style presentation should match the replacement tire to the vehicle’s actual wheel package.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2018 Nissan Trucks Murano?
Yes, modifications can affect tire fitment on a 2018 Nissan Trucks Murano. Changes such as aftermarket wheels, altered wheel widths, suspension lowering, or body modifications can change the space available around the tire and may also change which size is currently mounted. That matters on a Murano that originally came with either an 18-inch or 20-inch setup.
A modified vehicle should be checked for actual wheel diameter, tire size, and clearance at full steering lock before replacement tires are chosen. It also helps to inspect how close the current tires sit to struts, liners, and fender edges. Small changes in wheel package can have a larger effect than the model name alone suggests.
What should I inspect before driving a 2018 Nissan Trucks Murano on new tires?
Before driving a 2018 Nissan Trucks Murano on new tires, inspect that the installed size matches the vehicle’s wheel diameter and trim setup, then check inflation pressure, lug torque, and basic clearance. The sidewall should confirm either 235/65R18 or 235/55R20 as appropriate. It is also wise to look for even seating on the rim and any obvious rubbing points.
A short test drive should include listening for contact during turns and watching for vibration that may point to balance or mounting issues. After a little road use, inspect the tires again for air loss or unusual marks. That early check is especially useful if the Murano has replacement wheels or any suspension changes.
How often should tires on a 2018 Nissan Trucks Murano be inspected?
Tires on a 2018 Nissan Trucks Murano should be inspected regularly, not just when tread looks low. A routine visual check for uneven wear, cuts, bulges, cracking, and pressure loss helps catch problems before they become road-use issues. That applies whether the Murano is on 235/65R18 tires or the 235/55R20 setup.
Owners should also look more closely before longer trips, after pothole impacts, or anytime steering feel changes. Tire inspection is especially important on vehicles that sit for stretches between drives, since age and low use can hide problems. Keeping an eye on wear patterns can also reveal alignment or suspension issues before a tire is ruined.
