The 2019 Lexus Trucks NX300h blends compact luxury crossover packaging with hybrid efficiency, making tire fitment a practical part of how the vehicle rides, handles, and presents on the road. For this model year, the NX300h uses radial tires in two primary sizes, 225/65R17 and 225/60R18, so the first step is confirming which wheel diameter is actually on the vehicle. That choice shapes both replacement size and product selection. Owners comparing options often balance everyday road manners with wheel appearance and intended use. A careful match starts with the installed rim, then moves to tire type, load needs, and any changes from the original wheel setup.
Which Tire Size Is Right for The 2019 Lexus Trucks NX300h
The 2019 Lexus Trucks NX300h uses two primary tire sizes, and the difference comes down to wheel diameter: 17-inch or 18-inch rims. Both are radial metric sizes, so the key decision is confirming the exact wheel setup on the vehicle before choosing a tire. Once that is settled, the selection process becomes a matter of finding the right tire type, specifications, and intended use within the correct size.
225/60R18 is a metric radial size where 225 identifies the nominal section width in millimeters, 60 is the aspect ratio, R indicates radial construction, and 18 is the rim diameter in inches. On a 2019 Lexus Trucks NX300h, this size suits vehicles equipped with 18-inch wheels and keeps the fitment in a modern radial format consistent with contemporary crossover use. Its sizing convention is familiar to most late-model owners and makes comparison shopping straightforward. The practical priority is verifying the installed wheel diameter and checking that any replacement tire matches the vehicle’s load and clearance requirements.
225/65R17 is also a metric radial size, with a 225-millimeter nominal section width, a 65-series profile, radial construction, and fitment for a 17-inch rim. For the 2019 Lexus Trucks NX300h, this size applies to vehicles running 17-inch wheels rather than the 18-inch setup. Available product choice in this size can matter as much as the size itself, especially when comparing more road-focused replacement tires with a more aggressive all-terrain style. It is a size worth evaluating carefully if the NX300h has aftermarket wheels or if the goal is to balance appearance, road use, and rim-width compatibility.
Fitment is straightforward here because the covered sub-model shares the same two tire-size paths used on the broader 2019 Lexus Trucks NX300h fitment. The important step is confirming whether the vehicle is riding on 17-inch or 18-inch wheels before selecting a replacement tire.

Tire Size & Fitment
What tire size fits a 2019 Lexus Trucks NX300h?
The 2019 Lexus Trucks NX300h uses two primary tire sizes: 225/65R17 and 225/60R18. Both are radial metric sizes, and the correct one depends on whether the vehicle has 17-inch or 18-inch wheels installed.
Choosing between them is not a matter of preference alone, because each size is tied to a different rim diameter. A quick check of the tire sidewall or wheel size on the vehicle will confirm which fitment applies. If the NX300h has aftermarket wheels, verify the actual wheel diameter and width before ordering a replacement tire.
What size rim does a 2019 Lexus Trucks NX300h use?
A 2019 Lexus Trucks NX300h uses either a 17-inch or 18-inch rim, depending on which tire size is on the vehicle. The 225/65R17 size fits a 17-inch rim, while the 225/60R18 size fits an 18-inch rim.
That makes rim diameter the first thing to confirm before selecting tires. Even though the two tire sizes are close in overall diameter, they are not for the same wheel. Checking the wheel itself and reading the existing tire sidewall will help prevent ordering a tire that matches the vehicle generally but not the actual wheel setup.
Does the 2019 Lexus Trucks NX300h Base use the same tire size?
The 2019 Lexus Trucks NX300h Base can use the same two tire sizes associated with this model: 225/65R17 and 225/60R18. Both are radial sizes, and the correct one is determined by the wheel diameter installed on the vehicle.
For the Base sub-model, the tire decision starts with wheel confirmation rather than trim identification alone. Once the rim diameter is known, the replacement process becomes much simpler. It is also smart to check whether the vehicle still has its original wheel setup, since a previous owner may have changed wheels without changing the trim designation.
Choosing the Right Tire
What should I consider when choosing a 225/65R17 tire for a 2019 Lexus Trucks NX300h?
Start with the basics: correct size, radial construction, and compatibility with a 17-inch wheel. In 225/65R17, one available option is the BFGoodrich All Terrain T/A KO2, which carries a 2,150 lbs maximum load at 65 psi, uses a 6.0 to 8.0-inch rim-width range, and has an RBL sidewall.
That kind of specification makes it important to think about how the NX300h is actually used. A more aggressive all-terrain style may appeal to some owners for appearance or mixed-use driving, but wheel width, ride expectations, and the overall setup still need to be checked. Matching the tire to both the rim and the vehicle’s intended use is the key decision.
What sidewall styles are available for 2019 Lexus Trucks NX300h tires?
For the currently available 225/65R17 product choice, the sidewall style is RBL. That gives the tire a different visual character than a plain blackwall and can matter to owners who want a more assertive, utility-oriented appearance on the NX300h.
Sidewall style is mostly an appearance decision, but it should come after the correct size and wheel fitment are confirmed. Once the tire size is right, sidewall treatment helps refine the look of the vehicle without changing the basic fitment. It is best to compare sidewall style alongside tire series, load capacity, and intended driving use.
What brands offer tires for the 2019 Lexus Trucks NX300h?
Among the currently available products for this fitment, BFGoodrich appears in 225/65R17 with the All Terrain T/A KO2 series. That gives NX300h owners at least one clearly defined product path in the 17-inch size with a recognizable all-terrain style and radial construction.
Brand alone should not make the decision. The better approach is to confirm the vehicle’s actual tire size first, then compare the available tire’s construction, rim-width compatibility, sidewall style, and load specifications. That keeps the focus on choosing a tire that suits the NX300h’s wheel setup and intended use rather than choosing by name only.
Restoration & Appearance
Which tire should I choose for a period-style 2019 Lexus Trucks NX300h?
A 2019 Lexus Trucks NX300h is a modern luxury hybrid crossover, so the appearance conversation is usually less about vintage restoration and more about preserving the vehicle’s original visual balance. Staying with the correct 225/65R17 or 225/60R18 size is the most important starting point for a clean, appropriate presentation.
From there, the choice comes down to the look you want within the correct fitment. A more aggressive tread and sidewall treatment can give the NX300h a tougher visual stance, while a more road-oriented tire keeps a more understated appearance. Any appearance choice should still respect wheel diameter, tire dimensions, and normal clearance around the vehicle.
Does correct tire fitment matter for a 2019 Lexus Trucks NX300h restoration or preservation project?
Correct tire fitment matters because it affects both appearance and how the 2019 Lexus Trucks NX300h sits on its wheels. Using the proper 225/65R17 or 225/60R18 size helps maintain the intended proportions and avoids the visual mismatch that can come from using the wrong rim diameter or an unsuitable replacement size.
Preservation-minded owners should confirm what wheel package is actually on the vehicle before replacing tires. That is especially important on used examples, where wheel changes are common. Even on a newer collector vehicle, the right tire size supports a more coherent presentation and reduces the chances of avoidable fitment issues at the fender, suspension, or steering range.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2019 Lexus Trucks NX300h?
Yes, modifications can change tire fitment on a 2019 Lexus Trucks NX300h even when the basic size looks close. Aftermarket wheels, changes in wheel width, altered offset, suspension lowering, or body modifications can all affect how a 225/65R17 or 225/60R18 tire sits and clears during normal driving and steering.
That means the safest approach is to treat the actual vehicle as the final reference point. Check wheel diameter first, then verify width and available clearance at full steering lock and through suspension travel. A tire that matches the original size code still needs to be appropriate for the wheel and the modified setup now on the vehicle.
What should I inspect before driving a 2019 Lexus Trucks NX300h on new tires?
Before road use, inspect the wheel and tire package as a whole. Confirm the size matches the installed rim, look for proper seating on the wheel, and check tire pressure, sidewall condition, and any visible cuts, bulges, or irregularities that could indicate damage or mounting problems.
It also helps to check for clearance around the strut, fender liner, and steering components once the tire is installed. A short, careful test drive can reveal rubbing, vibration, or pull that should be corrected early. On a vehicle like the NX300h, proper inflation and a clean fitment check go a long way toward smooth everyday road manners.
How often should tires on a 2019 Lexus Trucks NX300h be inspected?
Tires on a 2019 Lexus Trucks NX300h should be inspected regularly rather than only when a problem appears. Frequent visual checks for uneven wear, air loss, cracking, punctures, and sidewall damage are especially worthwhile on a vehicle that may see mixed city driving, highway use, or longer periods between high-mileage trips.
A routine inspection habit helps catch fitment or wear issues before they become more serious. Owners should also pay attention after pothole impacts, wheel changes, or any suspension work. Even when tread looks acceptable, pressure condition and visible aging still matter, particularly on a low-use vehicle where time and storage can affect tires as much as mileage.
