The 2023 Lexus Trucks NX450h+ brings the NX into the plug-in hybrid era with a blend of luxury, efficiency, and everyday crossover usability. Its modern chassis, refined road manners, and upscale character make tire choice less about chasing multiple factory sizes and more about preserving the vehicle’s intended balance of comfort, response, and appearance. This model uses a 235/50R20 radial tire on a 20-inch rim. Because both the Base and F Sport share that same fitment, the main decision centers on selecting the right tire within that size and confirming compatibility if the vehicle has been modified. Careful attention to wheel specs, tire condition, and road-use priorities still matters.
Which Tire Size Is Right for The 2023 Lexus Trucks NX450h+
The 2023 Lexus Trucks NX450h+ uses one primary tire size: 235/50R20, and it is a radial fitment on a 20-inch rim. That same size is used across the Base and F Sport sub-models, so the question is not which primary size applies, but how to choose the right tire in that size and verify wheel compatibility if anything on the vehicle has been changed.
A 235/50R20 tire uses a 235-millimeter nominal section width, a 50-series aspect ratio, radial construction, and a 20-inch rim diameter. On the 2023 Lexus Trucks NX450h+, this modern metric radial sizing matches the vehicle’s contemporary crossover design and road-focused driving character. The practical choice within this size usually comes down to keeping the correct dimensions for the wheel, maintaining the intended look and stance, and confirming that any replacement tire matches the actual wheel setup on the vehicle. That becomes especially important if aftermarket wheels or suspension changes are involved.
Tire fitment is straightforward across the covered 2023 Lexus Trucks NX450h+ sub-models. Both the Base and F Sport use the same 235/50R20 radial size, so sub-model selection matters more for confirming the exact vehicle than for sorting through different primary tire sizes.

2023 Lexus Trucks NX450h+ Base
The 2023 Lexus Trucks NX450h+ Base uses the same 235/50R20 radial fitment as the other covered sub-model. That keeps tire selection focused on staying with the correct size and 20-inch wheel fitment while checking actual wheel specifications if the vehicle no longer has its original setup.
The 2023 Lexus Trucks NX450h+ F Sport also uses 235/50R20 radial tires. Since the primary fitment does not change, the key step is choosing a tire that suits the vehicle’s intended road use and confirming clearance and wheel compatibility if any modifications have been made.
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 2023 Lexus Trucks NX450h+ tire size, 20-inch rim fitment, sub-model consistency, tire selection, modification checks, and the maintenance points worth reviewing before regular road use.
Tire Size & Fitment
What tire size fits a 2023 Lexus Trucks NX450h+?
The 2023 Lexus Trucks NX450h+ uses a 235/50R20 radial tire. That is the primary tire size for this model and it applies to the covered vehicle fitment rather than a mix of different factory sizes.
A 235/50R20 size means the tire is built for a 20-inch wheel, so confirming actual wheel diameter is still important before replacement. If the vehicle has aftermarket wheels, replacement suspension parts, or any ride-height changes, it is smart to verify wheel width, clearance, and the full tire dimensions before choosing a new set.
What size rim does a 2023 Lexus Trucks NX450h+ use?
The 2023 Lexus Trucks NX450h+ uses a 20-inch rim with its 235/50R20 tire size. The tire’s size code and fitment both point to a 20-inch wheel diameter for this application.
Wheel diameter is only one part of fitment, so it helps to check the actual wheel on the vehicle before mounting new tires. Width and offset can affect how a tire sits and how much room it has at the strut, fender, and steering components, especially if the NX450h+ no longer has its original wheels.
Do all 2023 Lexus Trucks NX450h+ sub-models use the same tire size?
Yes. The covered 2023 Lexus Trucks NX450h+ Base and F Sport sub-models both use the same 235/50R20 radial tire size. That makes fitment more straightforward than a vehicle line where trims split across different wheel and tire packages.
Even with shared sub-model sizing, it is still worth checking the actual wheel setup on the vehicle in front of you. A previous owner may have changed wheels or suspension, and that can affect tire selection even when the original fitment is the same across the model range.
Choosing the Right Tire
What should I consider when choosing a 235/50R20 tire for a 2023 Lexus Trucks NX450h+?
Start with the correct 235/50R20 size and radial construction, since that is the primary fitment for the 2023 Lexus Trucks NX450h+. From there, the main considerations are keeping the proper dimensions for the 20-inch wheel and selecting a tire that suits how the vehicle is actually driven.
A replacement tire should be checked against the wheel width and the available clearance around suspension and body components. Daily commuting, longer highway use, and a preference for ride comfort versus a firmer response can all influence the final choice, but the correct size remains the foundation of a proper fitment decision.
How do I choose between available 235/50R20 tires for a 2023 Lexus Trucks NX450h+?
The best way to compare 235/50R20 tires for a 2023 Lexus Trucks NX450h+ is to begin with fitment, then look at construction details and how the tire will be used. Because this model uses one primary size, selection is more about choosing the right tire within that size than sorting through multiple factory fitments.
Focus on whether the tire matches the wheel and maintains proper clearance at full steering lock and through suspension travel. It also helps to think about the vehicle’s role in your garage, whether that is regular street driving, mostly local use, or a carefully maintained luxury crossover that sees lighter seasonal mileage.
What rim-fitment details should I compare when choosing 2023 Lexus Trucks NX450h+ tires?
The most important rim-fitment detail is the 20-inch wheel diameter required by the 235/50R20 tire size. After that, wheel width and offset deserve attention because they affect how the tire seats on the rim and how much space it has around the suspension and body.
Those checks matter most when the vehicle has non-original wheels or other changes from stock configuration. A tire can share the correct nominal size and still create clearance issues if the wheel setup has changed, so measuring the actual wheel and reviewing the vehicle’s present stance is a smart step before purchase.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2023 Lexus Trucks NX450h+?
Yes. Modifications can affect tire fitment on a 2023 Lexus Trucks NX450h+ even when the original size is 235/50R20. Changes to wheels, offset, suspension height, alignment settings, or body clearance can alter how much room the tire has in real driving conditions.
A useful check includes wheel diameter, wheel width, steering clearance, and space at the inner fender and suspension. Lowering springs, larger aftermarket wheels, or spacer use can all change the fitment picture, so the safest approach is to confirm the vehicle’s current setup rather than relying only on factory-size assumptions.
What should I inspect before driving a 2023 Lexus Trucks NX450h+ on new tires?
Before driving a 2023 Lexus Trucks NX450h+ on new tires, inspect wheel condition, confirm the tires are the correct 235/50R20 size, and make sure inflation is set appropriately for the application. It also helps to verify that each tire clears properly at full steering lock and under normal suspension movement.
A quick road-use check should also include lug-nut torque, visible sidewall condition, and any signs of rubbing once the vehicle is driven and turned through its normal range. After the first short drive, rechecking pressure and looking for uneven contact or clearance marks can catch fitment issues early.
How often should tires on a 2023 Lexus Trucks NX450h+ be inspected?
Tires on a 2023 Lexus Trucks NX450h+ should be inspected regularly, not only when tread looks low. Frequent visual checks for cuts, bulges, punctures, irregular wear, and pressure loss are especially worthwhile on a vehicle that may alternate between daily use and periods of lighter mileage.
A consistent routine helps spot small issues before they become drivability or safety concerns. Looking at the tread and sidewalls during washing, before longer trips, and after striking potholes or road debris is a sensible habit, and any vibration, pull, or repeated air loss deserves prompt attention from a qualified tire professional.
