The 2015 Lexus Trucks NX300h arrived as part of Lexus' move into the compact luxury crossover market, blending hybrid efficiency with the higher seating position and everyday versatility many buyers wanted. It is a modern vehicle by Coker Tire standards, so the tire decision is centered less on vintage construction and more on confirming the exact wheel setup on the vehicle. This NX300h uses radial tires in either 225/60R18 or 225/65R17, depending on the wheel package. That makes wheel diameter the first checkpoint, followed by the type of road use and tire character you want. A careful match matters most if the vehicle has seen wheel changes since new.
Which Tire Size Is Right for The 2015 Lexus Trucks NX300h
Two tire sizes apply to the 2015 Lexus Trucks NX300h, and both are radial sizes tied to different wheel diameters. The key step is confirming whether the vehicle is running 17-inch or 18-inch wheels, because that determines whether 225/65R17 or 225/60R18 is the proper fitment path. Since the same sub-model can appear with either size, the wheel on the vehicle matters more than the badge on the tailgate.
In 225/60R18, the 225 identifies the nominal section width in millimeters, the 60 is the aspect ratio, the R marks radial construction, and the 18 is the wheel diameter in inches. This is a modern radial size suited to NX300h vehicles equipped with 18-inch wheels. Its practical role is straightforward: matching the correct wheel diameter while keeping the proper tire profile for that setup. If the vehicle currently wears 18-inch wheels, this is the size to evaluate first before comparing tread type, ride character, and overall condition of the existing wheel and suspension package.
In 225/65R17, the 225 is the nominal section width in millimeters, the 65 is the aspect ratio, the R indicates radial construction, and the 17 identifies the wheel diameter in inches. This size applies to NX300h vehicles using 17-inch wheels rather than the 18-inch package. Available product choice in this size includes BFGoodrich's All-Terrain T/A KO2 with an RBL sidewall, giving buyers a more utility-focused option than a typical highway-oriented crossover tire. It is the size to consider only after confirming the vehicle actually has a 17-inch wheel setup.
Fitment is simple in one way and important in another: the covered NX300h sub-model is the Base, but it can use either of the two radial tire sizes. That means tire selection depends on confirming the actual wheel diameter on the vehicle rather than assuming one size applies to every Base model.

2015 Lexus Trucks NX300h Base
The 2015 Lexus Trucks NX300h Base can use either 225/60R18 or 225/65R17, both in radial construction. The practical choice comes down to the wheel package currently on the vehicle, so verifying whether it has 17-inch or 18-inch rims should come before comparing tire style or intended 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.
Best 2015 Lexus Trucks NX300h Tires for Sale
Current product coverage is concentrated in 225/65R17, where BFGoodrich offers an All-Terrain T/A KO2 radial with an RBL sidewall. That gives buyers a chance to compare fitment not just by size, but also by tire character, rim-width range, and a more rugged visual style.
Owners of a 2015 Lexus Trucks NX300h usually need clarity on the two possible tire sizes, the difference between 17-inch and 18-inch wheel fitment, and how to choose a tire that suits everyday driving, appearance, and vehicle condition.
Tire Size & Fitment
What tire size fits a 2015 Lexus Trucks NX300h?
The 2015 Lexus Trucks NX300h uses either 225/60R18 or 225/65R17, and both are radial tire sizes. The correct one depends on the wheel package on the vehicle, since one size is built for an 18-inch rim and the other is built for a 17-inch rim.
The most important next step is checking the actual wheel diameter on the NX300h before choosing a tire. Since the Base sub-model can appear with either size, it is better to confirm the wheel itself, the current tire placard, and the vehicle's present setup rather than selecting by model name alone.
What size rim does a 2015 Lexus Trucks NX300h use?
A 2015 Lexus Trucks NX300h can use either a 17-inch or 18-inch rim, depending on which tire size is on the vehicle. The 225/65R17 tire fits a 17-inch rim, while the 225/60R18 tire fits an 18-inch rim.
That rim difference is the key fitment divider for this vehicle. A buyer should confirm the wheel diameter stamped on the wheel or verify the size already mounted before comparing tires, because the two sizes have similar width but are not meant for the same wheel diameter.
Why does the 2015 Lexus Trucks NX300h have more than one tire size?
The 2015 Lexus Trucks NX300h has more than one tire size because it was fitted with different wheel packages. One setup uses 225/65R17 on a 17-inch rim, and another uses 225/60R18 on an 18-inch rim, with both staying in radial construction.
That means the decision is not about choosing whichever size seems closest. It is about matching the tire to the wheel actually on the vehicle and then checking for any past wheel changes, accessory packages, or aftermarket replacements that may have altered the original wheel-and-tire combination.
Choosing the Right Tire
What should I consider when choosing a tire for a 2015 Lexus Trucks NX300h?
Start with the exact tire size already matched to the vehicle's wheel diameter, because the 2015 Lexus Trucks NX300h uses either 225/60R18 or 225/65R17. From there, compare construction, intended use, load capacity, rim-width compatibility, and the overall character of the tire you are considering.
A daily-driven NX300h may need a different tire approach than one used in rougher conditions or on secondary roads. It also helps to check whether the vehicle still has its original wheels, because an aftermarket wheel change can affect which size should be evaluated first and how the tire sits on the rim.
What brands offer tires for the 2015 Lexus Trucks NX300h?
BFGoodrich is available for the 2015 Lexus Trucks NX300h in the covered product range, specifically in 225/65R17. That option appears in the All-Terrain T/A KO2 series, giving the NX300h buyer at least one clearly defined product path in the 17-inch fitment.
Brand choice matters most after size and wheel diameter are confirmed. Once the NX300h is matched to the correct 17-inch or 18-inch setup, the buyer can compare the available brand's tread character, load figure, sidewall style, and rim-width range against how the vehicle is actually being used.
How do I choose between the available 225/65R17 tires for a 2015 Lexus Trucks NX300h?
Choosing a 225/65R17 tire for a 2015 Lexus Trucks NX300h starts with confirming that the vehicle has 17-inch wheels. In the available coverage, BFGoodrich offers the All-Terrain T/A KO2 in this size, with radial construction, an RBL sidewall, a 6.0 to 8.0 inch rim-width range, and a 2,150-pound load capacity at 65 psi.
Those details help frame whether the tire suits the way the NX300h is used. A buyer should compare wheel width, desired appearance, and road conditions, then make sure the tire's more rugged character aligns with the crossover's current setup rather than assuming any 225/65R17 tire will serve the same purpose.
Restoration & Appearance
Does correct tire fitment matter for a 2015 Lexus Trucks NX300h restoration?
Correct tire fitment still matters on a 2015 Lexus Trucks NX300h, even though it is not a vintage restoration in the traditional sense. Using the proper 225/60R18 or 225/65R17 size keeps the vehicle aligned with its wheel package and preserves the proportions intended for that particular setup.
Appearance can change noticeably when the wrong profile is installed, especially on a modern crossover where wheel and tire balance is a big part of the visual presentation. Buyers trying to return the vehicle to a clean, factory-inspired look should confirm the existing wheels first and avoid mixing sizes meant for different rim diameters.
How does tire construction affect the appearance of a restored 2015 Lexus Trucks NX300h?
On a 2015 Lexus Trucks NX300h, tire construction is straightforward because the primary fitments are radial sizes rather than vintage bias-ply formats. The visual difference comes less from construction type and more from tread pattern, sidewall treatment, and whether the tire presents a highway-oriented or more aggressive utility look.
That is especially relevant in 225/65R17, where an RBL all-terrain option gives the vehicle a tougher stance than a typical road-focused crossover tire. For a clean restoration-oriented presentation, owners should think about how the sidewall and tread style complement the wheels and overall finish of the vehicle.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2015 Lexus Trucks NX300h?
Yes, modifications can affect tire fitment on a 2015 Lexus Trucks NX300h. Wheel swaps, offset changes, suspension alterations, and even small ride-height changes can influence which tire size works properly and how much clearance remains at the fender, strut, and steering components.
That matters even when staying close to the original sizes, because the NX300h already has two legitimate fitment paths tied to different rim diameters. Anyone evaluating replacement tires should confirm the actual wheel size, inspect the current setup for modifications, and check turning and suspension clearance before settling on a tire.
What should I inspect before driving a 2015 Lexus Trucks NX300h on new tires?
Before driving a 2015 Lexus Trucks NX300h on new tires, inspect wheel condition, verify that the tire size matches the wheel diameter, and check that inflation pressure is appropriate for the installed tire. It is also smart to look over the valve stems, lug hardware, and general condition of the suspension and alignment.
A quick road-use inspection should also include tread clearance at full steering lock and a visual check for rubbing points inside the wheelhouse. On a vehicle that may have had wheel changes over time, that extra attention helps confirm the new tires are seated properly and working with the actual setup on the vehicle.
How often should tires on a 2015 Lexus Trucks NX300h be inspected?
Tires on a 2015 Lexus Trucks NX300h should be inspected regularly, not just when replacement time arrives. Frequent checks for uneven wear, sidewall cuts, embedded debris, cracking, and gradual air loss are especially worthwhile on a crossover that may see changing weather, mixed road conditions, and daily-use mileage.
Inspection becomes even more important after pothole impacts, curb contact, or any recent wheel or suspension work. Keeping an eye on wear pattern and pressure helps catch alignment or fitment issues early, which is useful on an NX300h that can be equipped with either 17-inch or 18-inch wheel-and-tire combinations.
