The 2023 Lexus Trucks NX350 blends compact luxury-crossover comfort with the sharper styling and road manners expected from a modern Lexus. For owners, tire choice is less about vintage-style construction and more about confirming the exact wheel setup on the vehicle, because this NX350 uses either 235/60R18 or 235/50R20 radial tires depending on configuration. That makes rim diameter the first fitment check before comparing replacement options. The decision then shifts to choosing the right tire within the correct size for ride character, appearance, and intended use. For daily driving, seasonal road use, or keeping a factory-inspired look, matching the tire to the wheel package matters most.
Which Tire Size Is Right for The 2023 Lexus Trucks NX350
The 2023 Lexus Trucks NX350 uses two primary tire sizes, and the difference comes down to configuration and wheel diameter. Both fitments are radial, but one uses an 18-inch rim and the other uses a 20-inch rim, so confirming the wheel size on the vehicle is the first step before selecting a tire. Once that is established, the real decision is choosing the right replacement within the correct size for driving needs and overall presentation.
235/50R20 is a modern metric radial size in which 235 identifies the nominal section width in millimeters, 50 is the aspect ratio, R indicates radial construction, and 20 is the rim diameter in inches. On the 2023 Lexus Trucks NX350, this size is part of the larger-wheel fitment and is used on a 20-inch rim. Its proportions reflect a lower-profile modern crossover tire format compared with the 18-inch alternative. This is the size to evaluate when the vehicle already wears 20-inch wheels and the goal is to stay with the same wheel-and-tire relationship.
235/60R18 is a modern metric radial size where 235 is the nominal section width in millimeters, 60 is the aspect ratio, R marks radial construction, and 18 is the rim diameter in inches. On the 2023 Lexus Trucks NX350, this size corresponds to the 18-inch wheel fitment rather than the 20-inch setup. Compared with the larger-rim alternative, it represents a different wheel-and-tire package rather than just a different tire choice. This size should be selected only after confirming that the NX350 is equipped with 18-inch wheels.
Tire fitment on the 2023 Lexus Trucks NX350 depends on the exact sub-model and wheel package. Checking the sub-model matters because the F Sport uses a different fitment pattern than the Base, and rim diameter is central to choosing the right tire.

2023 Lexus Trucks NX350 Base
The 2023 Lexus Trucks NX350 Base can use either of the two primary radial tire sizes, so wheel diameter must be confirmed before replacement. Once the 18-inch or 20-inch setup is identified, selection becomes a matter of choosing the right tire within that correct size.
The 2023 Lexus Trucks NX350 F Sport uses the 235/50R20 radial fitment, tying it to the 20-inch wheel package. That makes tire selection more straightforward, since the main task is staying with the correct size and comparing replacement options within that format.
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
These FAQs focus on the two tire sizes used on the 2023 Lexus Trucks NX350, how sub-model fitment differs, and what to verify before replacing tires on 18-inch or 20-inch wheel packages.
Tire Size & Fitment
What tire size fits a 2023 Lexus Trucks NX350?
The 2023 Lexus Trucks NX350 uses either 235/60R18 or 235/50R20 radial tires. Both are primary fitments for this model, but they are tied to different wheel packages rather than being interchangeable choices on the same rim.
The first thing to verify is the wheel diameter actually on the vehicle. An NX350 with 18-inch wheels needs the 235/60R18 fitment, while a 20-inch setup uses 235/50R20. Checking the door placard, the wheel itself, and the current tire size helps prevent ordering a tire that matches the model name but not the actual wheel package.
What size rim does a 2023 Lexus Trucks NX350 use?
The 2023 Lexus Trucks NX350 uses either an 18-inch or 20-inch rim, depending on the tire fitment. The 235/60R18 tire is built for an 18-inch rim, while the 235/50R20 tire is built for a 20-inch rim.
Rim diameter is the most important fitment checkpoint on this vehicle because the two tire sizes are tied directly to two different wheel sizes. Before replacing tires, confirm the current wheel setup instead of relying only on the model name. That step is especially important if the NX350 was purchased used or if wheels were changed after delivery.
Do all 2023 Lexus Trucks NX350 sub-models use the same tire size?
No, the 2023 Lexus Trucks NX350 sub-models do not all use the same tire-size pattern. The Base can use either 235/60R18 or 235/50R20, while the F Sport uses 235/50R20.
That means identifying the exact sub-model helps, but it still may not be the only step for a Base model because wheel diameter must also be confirmed. A quick inspection of the existing tire sidewall or wheel size is the safest way to narrow the fitment. Once that is settled, the replacement decision becomes much more straightforward.
Choosing the Right Tire
What should I consider when choosing a 235/50R20 tire for a 2023 Lexus Trucks NX350?
A 235/50R20 tire for a 2023 Lexus Trucks NX350 needs to match the vehicle's 20-inch wheel setup first. After confirming that size, focus on the tire's intended use, such as everyday commuting, highway travel, or a balance of comfort and handling response.
It also helps to compare the replacement tire's overall character against what is already on the vehicle. Owners often want to preserve the sharper look and lower-profile appearance associated with the 20-inch package. Checking wheel condition, alignment, and wear patterns before installing a new set can prevent uneven wear from shortening tire life.
What should I consider when choosing a 235/60R18 tire for a 2023 Lexus Trucks NX350?
A 235/60R18 tire is the correct choice only for a 2023 Lexus Trucks NX350 equipped with 18-inch wheels. Once that is confirmed, the next consideration is choosing a tire that matches how the vehicle is used, whether that means daily driving, longer highway trips, or a comfort-focused replacement.
Because this size is part of a different wheel-and-tire package than the 20-inch fitment, it should not be treated as an alternate just because it is used somewhere within the same model line. Looking at current wear, ride expectations, and the condition of the suspension and alignment will help the new tires perform as intended.
How do I choose between the available tire sizes for a 2023 Lexus Trucks NX350?
The choice between 235/60R18 and 235/50R20 is not a matter of preference alone on a 2023 Lexus Trucks NX350. The correct size is determined by the wheel diameter already on the vehicle and, in some cases, by the specific sub-model.
That means the decision starts with verification, not substitution. Check the current tire sidewall, wheel size, and vehicle placard before selecting a replacement. Once the right size is confirmed, compare tires within that size rather than trying to move between the 18-inch and 20-inch fitments without also evaluating the complete wheel-and-tire setup.
Restoration & Appearance
Does correct tire fitment matter for a 2023 Lexus Trucks NX350 restoration or appearance refresh?
Yes, correct tire fitment matters because the 2023 Lexus Trucks NX350 was offered with distinct 18-inch and 20-inch wheel-and-tire packages. Using the wrong tire size can change the vehicle's visual balance and may also create fitment issues at the wheel, suspension, or body.
Even on a modern vehicle, appearance goals still need to respect the original wheel diameter in use. An owner refreshing the vehicle's presentation should keep the tire size tied to the actual wheels rather than choosing by looks alone. Matching the proper size helps preserve the intended stance and keeps the fitment process much more predictable.
How does tire profile affect the appearance of a 2023 Lexus Trucks NX350?
Tire profile has a noticeable effect on how a 2023 Lexus Trucks NX350 looks because the two primary sizes pair the same nominal width with different aspect ratios and rim diameters. The 235/50R20 presents a lower-profile look on a larger wheel, while the 235/60R18 belongs to the 18-inch package.
That difference is important when replacing tires on a vehicle you want to keep visually consistent. Staying with the existing wheel-and-tire package preserves the intended relationship between sidewall height and wheel size. If wheels have been changed, verify both the wheel diameter and the tire size together instead of judging fitment by appearance alone.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2023 Lexus Trucks NX350?
Yes, modifications can affect tire fitment on a 2023 Lexus Trucks NX350 even when the tire size appears close to the original setup. Changes to wheel diameter, wheel width, offset, ride height, or suspension components can alter how a tire clears the fenders, liners, and steering components.
That is why a modified NX350 should be checked as an individual vehicle before replacing tires. A tire that suits a stock 18-inch or 20-inch package may behave differently after aftermarket wheel or suspension changes. Clearance at full steering lock and through suspension travel is worth confirming before regular road use.
What should I inspect before driving a 2023 Lexus Trucks NX350 on new tires?
Before driving a 2023 Lexus Trucks NX350 on new tires, inspect the wheels for damage, confirm the tire size matches the wheel diameter, and make sure inflation is set correctly for the application. It is also wise to look for any suspension or alignment issues that may have caused irregular wear on the previous tires.
A short follow-up check after installation is helpful as well. Monitor for vibration, pulling, unusual noise, or contact during turning, especially if the vehicle has replacement wheels or previous modifications. Keeping an eye on pressure and tread wear during the first several hundred miles can reveal setup issues before they become more serious.
How often should tires on a 2023 Lexus Trucks NX350 be inspected?
Tires on a 2023 Lexus Trucks NX350 should be inspected regularly, not just when a problem appears. A quick visual check every few weeks and before longer trips helps catch uneven wear, punctures, cuts, bulges, and pressure loss before they turn into larger issues.
More frequent inspection is smart if the vehicle sees rough roads, seasonal use, or long highway drives. Pay close attention to tread condition, sidewall health, and any signs that the vehicle may need alignment service. Consistent inspection is especially useful on a model with two possible wheel packages, since size and wheel confirmation matter at replacement time.
