The 2018 Lexus Trucks NX300h blends compact luxury-crossover packaging with hybrid efficiency, making tire choice more about matching the vehicle’s exact wheel setup than chasing a vintage-style restoration decision. On this model, fitment centers on two radial sizes, 225/60R18 and 225/65R17, so the first step is confirming which wheel diameter is actually on the vehicle. That matters because both sizes are modern metric radials with very similar overall dimensions but different rim requirements. Once the wheel size is confirmed, the real comparison becomes construction consistency, road-use priorities, and whether the available tire choice suits the NX300h’s current setup and intended driving use.
Which Tire Size Is Right for The 2018 Lexus Trucks NX300h
The 2018 Lexus Trucks NX300h uses two primary tire sizes, and the key difference is wheel diameter: one size fits a 17-inch rim and the other fits an 18-inch rim. Because the NX300h Base can use either size, the first step is confirming the wheels currently on the vehicle before selecting a tire. After that, the decision shifts to choosing the right radial tire within the correct size and checking that its specifications suit the vehicle’s intended use.
225/60R18 is a metric radial size in which 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 the 2018 Lexus Trucks NX300h, this size is part of the vehicle’s modern radial fitment and belongs on an 18-inch wheel. Its overall dimensions keep it close in height to the alternate 17-inch package while requiring a different rim diameter. This is the size to evaluate when the NX300h is equipped with 18-inch wheels and you want to stay with the correct modern fitment format.
225/65R17 is also a metric radial size, with 225 indicating nominal section width in millimeters, 65 identifying the aspect ratio, R for radial construction, and 17 showing the required rim diameter in inches. For the 2018 Lexus Trucks NX300h, it serves as the alternate primary fitment for vehicles using 17-inch wheels. Available product choice in this size includes a BFGoodrich All Terrain T/A KO2 with an RBL sidewall, giving this fitment a more utility-oriented option. This size should be considered only after confirming the NX300h is running the 17-inch wheel package.
Fitment is straightforward here because the covered sub-model shares the same two primary tire sizes. Even so, checking the exact wheel diameter on the vehicle still matters, since the NX300h Base can be equipped with either the 17-inch or 18-inch radial setup.

Tire Size & Fitment
What tire size fits a 2018 Lexus Trucks NX300h?
The 2018 Lexus Trucks NX300h uses two primary tire sizes: 225/60R18 and 225/65R17. Both are radial sizes, and the correct one depends on which wheel package is on the vehicle. The NX300h Base can use either size, so there is not one universal answer without checking the wheels first.
A quick look at the sidewall of the current tires or the wheel diameter itself will tell you which fitment applies. Since one size is for a 17-inch rim and the other is for an 18-inch rim, choosing by size alone without confirming the wheel can lead to the wrong tire being selected.
What size rim does a 2018 Lexus Trucks NX300h use?
The 2018 Lexus Trucks NX300h uses either a 17-inch or 18-inch rim, depending on the tire size fitted to the vehicle. A 225/65R17 tire mounts on a 17-inch rim, while a 225/60R18 tire mounts on an 18-inch rim. Both fitments are part of the NX300h lineup.
Rim diameter should be confirmed before anything else, because tire size selection starts there. The two sizes have similar overall height, but they are not meant for the same wheel. Checking the wheel and the tire sidewall together is the safest way to match the replacement tire to the NX300h’s existing setup.
Why does the 2018 Lexus Trucks NX300h have more than one tire size?
The 2018 Lexus Trucks NX300h has more than one tire size because it was fitted with different wheel diameters. One setup uses 225/65R17 on a 17-inch rim, and the other uses 225/60R18 on an 18-inch rim. Both are primary radial fitments for this model.
That means tire choice is tied directly to the wheels currently installed on the vehicle, not just the model name. If the NX300h has had wheels changed at some point, the original assumption may no longer apply. Confirming the actual wheel diameter avoids ordering a tire that matches the vehicle on paper but not the current wheel package.
Choosing the Right Tire
What should I consider when choosing a tire for a 2018 Lexus Trucks NX300h?
Start with the correct primary size for the wheel on the vehicle: 225/65R17 for a 17-inch rim or 225/60R18 for an 18-inch rim. From there, compare radial construction, intended use, and any product specifications that matter to your driving needs, such as rim-width suitability, load capacity, and tire weight.
A daily-driven NX300h may call for a different tire character than one used in harsher weather or on rougher roads. The most useful approach is to confirm wheel size first, then compare the available tire’s design and specifications against how the vehicle is actually driven rather than choosing only by brand name.
What brands offer tires for the 2018 Lexus Trucks NX300h?
Current product availability for the 2018 Lexus Trucks NX300h includes BFGoodrich in the 225/65R17 size. That option is part of the All Terrain T/A KO2 series and uses radial construction. Brand choice therefore depends partly on which of the NX300h’s two primary sizes the vehicle is wearing.
Brand should be considered alongside size, wheel diameter, and tire type rather than as a stand-alone decision. Once the correct fitment is confirmed, compare the tire’s intended use and specifications to the vehicle’s setup. That matters especially if the NX300h has moved away from strictly on-road use or has had wheel changes.
What tire series are available for the 2018 Lexus Trucks NX300h?
Among the currently available products for the 2018 Lexus Trucks NX300h, the 225/65R17 size includes the BFGoodrich All Terrain T/A KO2 series. That points this fitment toward a more utility-oriented tire character rather than a simple replacement chosen only by dimensions.
Series matters because it helps define the tire’s purpose and overall presentation. Even when the size is correct, a crossover used mainly on pavement may need a different style of tire than one seeing rough roads or outdoor use. Matching the series to the NX300h’s actual driving conditions makes the size choice more useful.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2018 Lexus Trucks NX300h?
Yes, modifications can affect tire fitment on a 2018 Lexus Trucks NX300h. Wheel changes, altered offset, suspension modifications, or body changes can all influence how a 225/65R17 or 225/60R18 tire sits in the wheel opening and how much clearance it has during steering and suspension travel.
That matters even when the tire size itself is one of the correct primary fitments. If the NX300h has aftermarket wheels or ride-height changes, check wheel diameter, wheel width, and clearance at the fenders and suspension before replacing tires. A size that suits a stock setup may need closer verification on a modified vehicle.
What should I inspect before driving a 2018 Lexus Trucks NX300h on new tires?
Before driving a 2018 Lexus Trucks NX300h on new tires, inspect basic fitment and condition items such as correct size, proper inflation, bead seating, and visible clearance around the fenders and suspension. It is also worth checking that all four tires match the wheel diameter used on the vehicle.
A short, careful road test can help confirm there is no rubbing, vibration, or unusual steering response. After the first drives, recheck tire pressure and look for any signs of contact or uneven wear. Those simple checks help confirm the tires are working with the NX300h’s current wheel and suspension setup.
How often should tires on a 2018 Lexus Trucks NX300h be inspected?
Tires on a 2018 Lexus Trucks NX300h should be inspected regularly, not just when replacement time arrives. Routine checks should include tread condition, cuts, punctures, sidewall damage, irregular wear, and any noticeable loss of air pressure. Frequent visual inspection is especially useful on a vehicle that sees mixed weather or rougher road conditions.
Inspection should also follow any impact with potholes, curbs, or road debris, since those events can affect both tire condition and wheel integrity. Looking over the tires during normal maintenance intervals makes it easier to catch problems early. On a vehicle with either 17-inch or 18-inch fitment, that habit helps protect both ride quality and safe road use.
