The 2020 Lexus Trucks NX300h blends compact luxury-crossover packaging with hybrid efficiency, making tire choice as much about preserving the vehicle’s everyday character as matching the correct fitment. For this model, the key decision starts with wheel size, because the NX300h uses either 225/60R18 or 225/65R17 radial tires depending on sub-model and wheel setup. That keeps the focus on confirming whether the vehicle is on 17-inch or 18-inch rims before narrowing down product options. Owners balancing road use, replacement accuracy, or a changed wheel package should verify the actual wheel diameter on the vehicle before selecting a tire.
Which Tire Size Is Right for The 2020 Lexus Trucks NX300h
The 2020 Lexus Trucks NX300h uses two primary tire sizes, and both are radial fitments. The main difference is wheel diameter: one size fits a 17-inch rim and the other fits an 18-inch rim. Before choosing a tire, confirm the exact sub-model and the wheel size currently on the vehicle, since the Base model can appear with either setup while the Luxury model uses the 18-inch size.
225/60R18 is a metric radial size in which 225 identifies the nominal section width in millimeters, 60 is the aspect ratio, R designates radial construction, and 18 is the rim diameter in inches. On the 2020 Lexus Trucks NX300h, this size is part of the primary fitment range and is shared by the Luxury sub-model as well as some Base configurations. Its role in this application is tied first to the correct 18-inch wheel rather than to styling choices. Buyers should confirm the actual wheel setup on the vehicle, especially if wheels have ever been changed from stock diameter.
225/65R17 is also a metric radial size, with a 225-millimeter nominal section width, a 65-series profile, radial construction, and a 17-inch rim diameter. For the 2020 Lexus Trucks NX300h, this size applies to certain Base-model configurations and should not be treated as universal across every NX300h. Available product choice in this size is narrower here, with an all-terrain BFGoodrich option that adds a different character than a typical crossover street tire. It is important to match this size to the correct 17-inch wheel and intended use before moving forward.
Sub-model fitment matters on the 2020 Lexus Trucks NX300h because tire size is tied to wheel configuration rather than staying uniform across the range. The first step is confirming whether the vehicle is a Base or Luxury model and then checking the actual wheel diameter on the vehicle.

2020 Lexus Trucks NX300h Base
The 2020 Lexus Trucks NX300h Base can use either of the model’s primary radial tire sizes, so wheel diameter is the deciding factor. Tire selection starts with confirming whether the vehicle is on 17-inch or 18-inch rims, then narrowing the choice by driving use and available product style.
The 2020 Lexus Trucks NX300h Luxury uses the 225/60R18 radial fitment, which simplifies size selection compared with the Base model. The practical decision becomes choosing the right 18-inch tire for the vehicle’s current wheel setup and intended road use rather than sorting through multiple primary sizes.
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.

Tire Size & Fitment
What tire size fits a 2020 Lexus Trucks NX300h?
The 2020 Lexus Trucks NX300h uses two primary tire sizes: 225/60R18 and 225/65R17. Both are radial sizes, but they fit different wheel diameters, so the correct choice depends on whether the vehicle is equipped with 18-inch or 17-inch rims.
That means the first check is the actual wheel diameter on the vehicle, not just the model name on the badge. The Base sub-model can appear with either size, while the Luxury model uses 225/60R18, so confirming both sub-model and wheel setup helps avoid ordering a tire that matches the vehicle family but not the wheels on the vehicle.
What size rim does a 2020 Lexus Trucks NX300h use?
A 2020 Lexus Trucks NX300h can use either a 17-inch or 18-inch rim, depending on the tire size and sub-model configuration. The 225/65R17 tire fits a 17-inch rim, while the 225/60R18 tire fits an 18-inch rim.
Rim diameter is the non-negotiable starting point because a 17-inch tire cannot be mounted on an 18-inch wheel, and the reverse is also true. A quick wheel-size confirmation is especially important on used vehicles, because replacement wheels, seasonal wheel sets, or past upgrades can leave the vehicle wearing a different diameter than a buyer expects from the trim name alone.
Do all 2020 Lexus Trucks NX300h sub-models use the same tire size?
No. The 2020 Lexus Trucks NX300h does not use one tire size across every covered sub-model. The Base model can use either 225/60R18 or 225/65R17, while the Luxury model uses 225/60R18.
That difference makes sub-model identification useful, but wheel verification is still the final check. A Base model with 17-inch wheels needs the 17-inch tire size, and one with 18-inch wheels needs the 18-inch size, so the badge alone is not always enough to settle the decision without looking at the wheel and current tire markings.
Choosing the Right Tire
What should I consider when choosing a tire for a 2020 Lexus Trucks NX300h?
Start with the correct primary size for the vehicle’s wheel diameter: 225/60R18 or 225/65R17. From there, compare the tire’s construction, intended use, and any relevant specifications such as rim-width compatibility, load capacity, and overall type, especially if the vehicle is used for more than routine street driving.
A 2020 Lexus Trucks NX300h with stock-style road use may call for a different tire character than one that sees rougher surfaces or seasonal duty. Matching the tire to the actual wheel, the way the vehicle is driven, and the current suspension and clearance setup will usually matter more than choosing by brand name alone.
What brands offer tires for the 2020 Lexus Trucks NX300h?
Available product coverage here includes BFGoodrich for the 225/65R17 fitment. The BFGoodrich offering is the All Terrain T/A KO2, which gives this size a more rugged all-terrain option than a purely road-oriented replacement approach.
Brand choice only becomes meaningful after the right size and wheel diameter are confirmed. Once that is settled, compare the tire’s intended use, sidewall presentation, and supporting specifications such as the approved rim-width range, since those details will affect how appropriate a given tire is for the way the NX300h is actually driven.
How do I choose between the available 225/65R17 tires for a 2020 Lexus Trucks NX300h?
For the 2020 Lexus Trucks NX300h, 225/65R17 selection starts with confirming that the vehicle is on a 17-inch wheel and that this is the correct size for the specific setup. In the available product range here, the BFGoodrich All Terrain T/A KO2 stands out as a radial all-terrain option with a 6.0- to 8.0-inch rim-width range.
That points the decision toward intended use as much as basic fitment. An owner who wants a tougher visual style or more off-pavement-oriented tire character may evaluate it differently than someone focused only on standard crossover street replacement, so wheel compatibility and real driving conditions should guide the final choice.
Restoration & Appearance
Does correct tire fitment matter for a 2020 Lexus Trucks NX300h restoration or preservation project?
Yes. Even on a modern luxury crossover like the 2020 Lexus Trucks NX300h, correct tire fitment matters if the goal is to preserve the vehicle’s intended stance, wheel relationship, and overall presentation. Using the proper primary size for the wheel diameter keeps the vehicle visually and mechanically aligned with its designed setup.
Preservation-minded owners should begin with the size tied to the actual wheel on the vehicle, then consider whether a tire’s appearance matches the character they want to maintain. If exact historical authenticity is important, trim-specific literature, window-sticker records, or marque-focused references can help confirm how that particular NX300h was originally equipped.
How does tire choice affect the appearance of a 2020 Lexus Trucks NX300h?
Tire choice affects the 2020 Lexus Trucks NX300h visually through wheel diameter, sidewall proportion, and tread character. Even when overall dimensions are close, a 17-inch setup with a 225/65R17 tire presents differently than an 18-inch setup with 225/60R18, and an all-terrain tread creates a more rugged look than a typical road-oriented tire.
That makes it worth thinking about appearance before settling on a replacement. Owners trying to preserve a clean luxury-crossover presentation may prioritize staying close to the existing wheel-and-tire look, while those using the vehicle in mixed conditions may accept a more aggressive visual style if it better suits how the NX300h is driven.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2020 Lexus Trucks NX300h?
Yes. Modifications can affect tire fitment on a 2020 Lexus Trucks NX300h, especially if the vehicle has aftermarket wheels, altered offset, suspension changes, or non-stock ride height. Even when the tire size looks close on paper, those changes can alter clearance at the fender, strut area, or during steering movement.
A modified NX300h should be checked as an individual vehicle rather than assumed to follow stock fitment patterns. Wheel diameter, wheel width, and surrounding clearance all matter, so it is smart to inspect the current setup carefully before replacing tires, particularly if the vehicle no longer sits on its original wheel-and-suspension combination.
What should I inspect before driving a 2020 Lexus Trucks NX300h on new tires?
Before driving a 2020 Lexus Trucks NX300h on new tires, check that the installed size matches the wheel diameter, verify proper inflation, and look over the wheels for damage or irregular seating. It also helps to make sure lug hardware is secure and that the tire clears suspension and body components through a full steering sweep.
A short initial road check is worthwhile after installation. Pay attention to vibration, rubbing, pulling, or unusual noise, then recheck air pressure and visual seating once the tires have settled in. Catching a mounting, balancing, or clearance issue early is much easier than discovering it after a longer trip.
How often should tires on a 2020 Lexus Trucks NX300h be inspected?
Tires on a 2020 Lexus Trucks NX300h should be inspected regularly, not only when tread looks worn. A routine visual check for cracking, punctures, bulges, uneven wear, and air loss is a sensible habit, and vehicles that sit for longer periods still need attention because age and storage conditions can affect tire condition.
Inspection is especially important before a season change, a highway trip, or after the vehicle has been parked for an extended time. Keeping an eye on pressure and wear patterns can also reveal alignment or suspension issues early, which helps protect both tire life and the vehicle’s road manners.
