The 2020 Lexus Trucks NX300 sits in the compact luxury crossover segment, where sharp styling, everyday road manners, and upscale comfort all matter as much as basic utility. Buyers looking at this exact model are usually balancing original-size fitment with the reality that wheel and trim choices can change the tire selection. The 2020 Lexus Trucks NX300 uses radial tires, with 225/65R17, 225/60R18, and 235/55R18 fitments depending on sub-model and wheel setup. That makes this page less about broad tire theory and more about confirming the correct size first, then considering road use, appearance, and wheel compatibility before choosing a replacement.
Which Tire Size Is Right for The 2020 Lexus Trucks NX300
Three tire sizes apply to the 2020 Lexus Trucks NX300, and the right one depends on sub-model and wheel diameter. Two sizes use 18-inch rims, while one uses a 17-inch rim, so the first step is confirming the exact sub-model and the actual wheel setup on the vehicle before comparing tire choices.
Fit(s): Base, Black Line Special Edition, F Sport, and Luxury
Construction: Radial|Rim: 18 in
225/60R18 is a metric radial size that identifies a 225-millimeter nominal section width, a 60-series aspect ratio, radial construction, and an 18-inch rim diameter. On the 2020 Lexus Trucks NX300, this size serves as one of the core 18-inch fitments and appears across multiple sub-models. It is a modern crossover-oriented sizing format familiar to current buyers, with the main selection question centered on matching the vehicle's exact trim and wheel package rather than interpreting an older tire code. Use this size when the NX300 is equipped with the correct 18-inch wheel setup and the sub-model calls for it.
225/65R17 is a metric radial size with a 225-millimeter nominal section width, a 65-series profile, and fitment for a 17-inch rim. For the 2020 Lexus Trucks NX300, this size belongs to specific configurations rather than the full model range, so it should not be treated as universal across all NX300 trims. Available product coverage in this size includes a BFGoodrich All Terrain T/A KO2 with an RBL sidewall treatment, giving it a more utility-focused character than a typical passenger-crossover replacement. This size is the one to evaluate only after confirming that the vehicle actually uses 17-inch wheels.
235/55R18 is a metric radial size that uses a 235-millimeter nominal section width, a 55-series aspect ratio, and an 18-inch rim diameter. On the 2020 Lexus Trucks NX300, it is tied to particular sub-model usage rather than the entire lineup, which makes exact configuration especially important before selecting a tire. Compared with the other primary sizes on this vehicle, the key point is not just rim diameter but also making sure the wider section width matches the intended wheel and trim setup. Choose this size only when the NX300 is already equipped for the 235/55R18 fitment.
Sub-model fitment matters on the 2020 Lexus Trucks NX300 because tire size is not the same across the entire range. Some trims share the 225/60R18 size, while others can use a second size, so confirming the exact sub-model and wheel diameter comes before selecting a tire.

2020 Lexus Trucks NX300 Base
The 2020 Lexus Trucks NX300 Base can use either a 225/60R18 or 225/65R17 radial tire, depending on the wheel setup on the vehicle. That makes wheel confirmation especially important before replacement, since the decision is not simply trim-based but also tied to whether the NX300 has 17-inch or 18-inch rims.
2020 Lexus Trucks NX300 Black Line Special Edition
The 2020 Lexus Trucks NX300 Black Line Special Edition uses the 225/60R18 radial size. Tire shopping for this sub-model is more straightforward, with the main task being to verify that the vehicle still carries its correct 18-inch wheel setup before comparing replacement options.
The 2020 Lexus Trucks NX300 F Sport can use either 225/60R18 or 235/55R18, both in radial construction and both on 18-inch rims. Because the rim diameter stays the same while the tire size changes, this sub-model calls for careful confirmation of the exact wheel-and-tire package already on the vehicle.
The 2020 Lexus Trucks NX300 Luxury uses the 225/60R18 radial size. For this sub-model, tire selection is primarily about staying with the proper 18-inch fitment and then comparing replacement characteristics that suit the vehicle's current wheels and intended 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.

Tire questions for the 2020 Lexus Trucks NX300 usually come down to confirming the right size by sub-model and wheel diameter, then comparing radial tire choices, rim fitment, and basic inspection steps before regular road use.
Tire Size & Fitment
What tire size fits a 2020 Lexus Trucks NX300?
The 2020 Lexus Trucks NX300 uses three primary tire sizes: 225/60R18, 225/65R17, and 235/55R18. All three are radial sizes, but they do not apply across every NX300 configuration, so the correct choice depends on the sub-model and the wheel package on the vehicle.
The practical first step is to verify both the trim and the actual wheel diameter already installed. A Base model can use either 17-inch or 18-inch fitment, and an F Sport can use two different 18-inch sizes, so checking the current tire sidewall and wheel setup helps prevent choosing the wrong replacement.
What size rim does a 2020 Lexus Trucks NX300 use?
The 2020 Lexus Trucks NX300 uses either a 17-inch or 18-inch rim, depending on the tire size and sub-model configuration. The 225/65R17 size fits a 17-inch rim, while both 225/60R18 and 235/55R18 fit 18-inch rims.
Rim diameter should be confirmed before looking at tread pattern or brand because two NX300 trims can share the same model name while using different wheel sizes. On an F Sport, even both primary sizes stay on an 18-inch rim, so the full tire size matters, not just the wheel diameter by itself.
Do all 2020 Lexus Trucks NX300 sub-models use the same tire size?
No, the 2020 Lexus Trucks NX300 sub-models do not all use the same tire size. Black Line Special Edition and Luxury use 225/60R18, while Base can use 225/60R18 or 225/65R17, and F Sport can use 225/60R18 or 235/55R18.
That variation means the model name alone is not enough when replacing tires on an NX300. The most reliable approach is to match the tire size already fitted to the vehicle and confirm that the wheels are original to the current setup, especially if the vehicle has changed hands or has been modified.
Choosing the Right Tire
What should I consider when choosing a tire for a 2020 Lexus Trucks NX300?
Start with the exact tire size the vehicle uses, since the 2020 Lexus Trucks NX300 can be fitted with 225/65R17, 225/60R18, or 235/55R18 depending on trim and wheel package. After size, compare construction, intended road use, rim compatibility, and any product-specific details that affect how the tire suits the vehicle.
A vehicle used mainly on pavement may call for a different type of replacement than one that sees rougher roads or seasonal conditions. The key is to keep the fitment decision grounded in the actual wheel diameter and the tire size already assigned to that NX300 configuration before comparing secondary features.
What brands offer tires for the 2020 Lexus Trucks NX300?
Current product coverage for the 2020 Lexus Trucks NX300 includes BFGoodrich in the 225/65R17 size. That available option is the All Terrain T/A KO2, which gives buyers a recognizable radial choice within the 17-inch fitment used on certain NX300 configurations.
Brand is only one part of the decision, especially on a model with multiple size combinations. It still makes sense to confirm that the tire's dimensions, rim-width compatibility, and overall intended use line up with the specific NX300 setup before focusing too heavily on brand preference alone.
How do I choose between the available 225/65R17 tires for a 2020 Lexus Trucks NX300?
For a 2020 Lexus Trucks NX300 that uses 225/65R17, begin by making sure the vehicle is one of the configurations that actually carries the 17-inch setup. Then compare the tire's construction, rim-width suitability, sidewall style, and intended use so the replacement matches how the NX300 will be driven.
The available 225/65R17 product coverage includes a BFGoodrich All Terrain T/A KO2 radial with an RBL sidewall and a 6.0-to-8.0-inch rim-width range. That kind of specification matters because it helps determine whether the tire suits the existing wheel and whether its character aligns with the way the vehicle is used.
Restoration & Appearance
Does correct tire fitment matter for a 2020 Lexus Trucks NX300 restoration?
Yes, correct tire fitment still matters on a 2020 Lexus Trucks NX300 even though it is a newer vehicle than a traditional restoration subject. Keeping the proper size, rim diameter, and overall tire profile helps preserve the vehicle's intended stance, appearance, and wheel-to-body relationship.
Appearance can change noticeably when an NX300 is fitted with the wrong size, even when the tire seems close at a glance. Anyone trying to return the vehicle to a more original-looking presentation should match the exact size used by that trim and confirm the wheels have not been changed from the factory-style setup.
How does tire choice affect the appearance of a 2020 Lexus Trucks NX300?
Tire choice affects the appearance of a 2020 Lexus Trucks NX300 through sidewall height, section width, and how the tire fills the wheel opening. A 225/65R17, 225/60R18, and 235/55R18 can all belong to this model range, but they create different visual relationships with the wheels and body.
That matters most when the goal is to keep the vehicle looking consistent with its trim and wheel package. Even on a modern crossover, a change in tire dimensions can alter the visual balance, so the best appearance result usually comes from staying with the exact size that belongs on that specific NX300 configuration.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2020 Lexus Trucks NX300?
Yes, modifications can affect tire fitment on a 2020 Lexus Trucks NX300. Aftermarket wheels, changes in wheel width, altered offset, suspension changes, or lowering can all influence whether the original 225/65R17, 225/60R18, or 235/55R18 sizing relationship is still appropriate on the vehicle.
That is why it helps to inspect the actual wheel-and-tire package rather than assuming every NX300 still matches its original trim configuration. Clearance at the fender, strut, and steering range should be reviewed carefully whenever the vehicle has been altered from a stock-style setup or carries replacement wheels.
What should I inspect before driving a 2020 Lexus Trucks NX300 on new tires?
Before driving a 2020 Lexus Trucks NX300 on new tires, inspect the tire size, wheel diameter, inflation pressure, and overall seating of the tire on the rim. It also makes sense to look over the wheels themselves for damage and confirm that no rubbing appears at full steering lock.
A short follow-up inspection after the first miles is also worthwhile, especially on a vehicle with multiple possible tire sizes. Recheck pressure, look for uneven contact or fresh scuffing, and make sure the selected size behaves normally in parking maneuvers, over bumps, and during routine road driving.
How often should tires on a 2020 Lexus Trucks NX300 be inspected?
Tires on a 2020 Lexus Trucks NX300 should be inspected regularly, not just when tread wear becomes obvious. Look at pressure, tread condition, cuts, bulges, sidewall damage, and any signs of uneven wear pattern so problems are caught before they become more serious.
Vehicles that sit for longer periods still need attention because age, heat, and storage conditions can affect tire condition even when mileage stays low. A routine visual check before longer drives, plus periodic pressure checks and close inspection for cracking or air loss, helps keep the NX300 road-ready.
