Lexus Trucks NX300 Tires

Lexus Trucks NX300 uses four tire sizes across the 2018 to 2021 model years: 225/65R17, 225/60R18, 235/55R18, and 235/50R19. The 225/65R17, 225/60R18, and 235/55R18 sizes appear from 2018 through 2021, while 235/50R19 appears for 2019 only. Their wheel diameters are built into the size codes, so they correspond to 17-inch, 18-inch, 18-inch, and 19-inch wheels respectively.

That means year alone is not enough to choose a tire for Lexus Trucks NX300. Start by checking the size currently mounted on the vehicle or the tire information placard, then match that to the wheel diameter first and the full size second. That step matters most on 2019 vehicles, where four different sizes are listed.

The 2019 Lexus Trucks NX300 has four sizes listed because that model year spans multiple wheel-and-tire packages: 225/65R17, 225/60R18, 235/55R18, and 235/50R19. The split is primarily a rim-diameter split, since those sizes cover 17-inch, 18-inch, and 19-inch wheels. Two of the options also share the same 18-inch rim diameter but use different widths and aspect ratios.

A 2019 Lexus Trucks NX300 owner should confirm the exact wheel diameter and the full sidewall size marking before replacing tires. If the vehicle has 18-inch wheels, do not assume both 18-inch sizes interchange without checking the original specification for that specific configuration. Width and sidewall profile affect overall dimensions and fit.

Lexus Trucks NX300 uses three rim diameters across the listed years: 17 inches, 18 inches, and 19 inches. The 17-inch fitment is 225/65R17, the 18-inch fitments are 225/60R18 and 235/55R18, and the 19-inch fitment is 235/50R19. Additional rim diameters beyond the earliest 17-inch fitment appear starting in 2018, and 19-inch fitment appears in 2019.

Wheel diameter is the first specification to verify because no tire can safely substitute for the wrong rim size. A Lexus Trucks NX300 with 17-inch wheels must stay with a 17-inch tire, and the same rule applies to 18- and 19-inch wheels. After that, confirm the full tire size so width and aspect ratio stay correct for the vehicle.

The correct tire size for a Lexus Trucks NX300 is confirmed by matching the exact size marking already on the vehicle and the wheel diameter it uses. Across 2018 to 2021, the listed sizes are 225/65R17, 225/60R18, 235/55R18, and for 2019 also 235/50R19. The size code itself tells you the wheel diameter, so the final number is a quick way to separate 17-, 18-, and 19-inch fitments.

A careful buyer should verify the full sidewall code rather than selecting by model year alone. That is especially important if the vehicle has had wheel changes or if two 18-inch options are possible. Matching both the wheel diameter and the complete size code helps preserve the intended overall fit and proportion.

The currently listed Lexus Trucks NX300 product information shows an RBL sidewall style for the available 225/65R17 tire. RBL indicates a raised black letter sidewall, which gives a more utilitarian and truck-oriented appearance than a plain blackwall. No additional sidewall styles are listed in the available product coverage here.

Sidewall style matters mostly for appearance, but it can also signal the character of the tire itself. On a Lexus Trucks NX300, an all-terrain tire with raised black letters will look and feel different from a touring-oriented road tire. If appearance matters, compare the vehicle's current look with the sidewall style before making a final choice.

The available Lexus Trucks NX300 product coverage here includes BFGoodrich. The listed product is a BFG All-Terrain T/A KO2 in LT225/65R17/D format, which is a radial all-terrain design for the 17-inch size. No other brands are shown in the current product set.

Brand matters less than matching the exact size, load capability, and intended use of the vehicle. A Lexus Trucks NX300 used mainly on pavement may call for a different tire character than one that regularly sees gravel, weather, or light trail work. Start with fitment, then consider how the tire's design suits the vehicle's real use.

A Lexus Trucks NX300 should be stored on a clean, dry surface away from direct sunlight, electric motors, welding equipment, and ozone sources that can accelerate rubber aging. Keep the tires inflated to an appropriate stored pressure for the vehicle's setup, and avoid letting the crossover sit for long periods with one spot of the tread carrying the full load. If storage will be lengthy, moving the vehicle slightly from time to time helps reduce flat-spotting.

Good storage habits matter because even modern radial tires age when they are not driven much. A Lexus Trucks NX300 that is used seasonally or only for occasional trips benefits from periodic movement, clean storage conditions, and visual checks for weathering. Those steps preserve ride quality and help catch age-related issues before the next drive.

Tires on a Lexus Trucks NX300 should be inspected regularly, with a quick visual check before driving and a more thorough inspection at routine service intervals. Look for cracking, punctures, bulges, uneven shoulder wear, embedded debris, and any sign that one tire size or type does not match the others on the same axle. Inflation pressure should also be checked with the tires cold.

Regular inspection is especially important when a Lexus Trucks NX300 sees mixed use, curb contact, or seasonal storage. Catching an alignment issue or underinflation early can prevent rapid wear and preserve handling. If the vehicle develops vibration, pulling, or unusual tread wear, inspect the tires immediately rather than waiting for the next service visit.

A Lexus Trucks NX300 tire should be replaced when age, cracking, structural damage, irregular wear, repeated air loss, or impact injury make continued use questionable, even if tread depth still appears usable. Tread alone is not the full measure of tire condition on a low-mileage luxury crossover. Aging rubber, sidewall damage, and internal belt problems can make an older tire unsuitable before it looks worn out.

That practical rule matters for vehicles that accumulate miles slowly but still spend years on the same set of tires. If a Lexus Trucks NX300 has older tires with visible weathering or a harsh, noisy, or unstable feel, replacement should move ahead of cosmetic tread concerns. A hands-on inspection by a qualified tire professional is the right next step when age becomes a factor.

A properly sized, correctly installed, and undamaged tire can be suitable for public-road use on a Lexus Trucks NX300, but safety depends on matching the exact size and wheel diameter, maintaining proper inflation, and using a tire whose condition is sound. The listed available product for 225/65R17 is a modern radial all-terrain design, which is fundamentally different from an obsolete collector-style casing. Safety still depends on the individual tire's age, condition, and suitability for the vehicle's use.

Before regular road driving, a Lexus Trucks NX300 owner should confirm that all four tires are the correct size, that tread wear is even, and that there are no cracks, bulges, or repairs that compromise serviceability. A road test should begin conservatively after any tire change. If the vehicle feels unstable, noisy, or vibration-prone, stop and inspect the setup.

Before driving a Lexus Trucks NX300, check cold inflation pressure, visible tire condition, tread depth, and the full size marking on each tire. Make sure the wheel diameter and tire size match side to side on each axle, and inspect for nails, sidewall damage, and any sign of rubbing. If the vehicle uses an all-terrain tire, also look for trapped stones or debris in the tread blocks.

These checks are quick but important because a Lexus Trucks NX300 may have several correct factory-style size possibilities, and mismatches can slip in after previous tire service or wheel changes. A short walk-around before a highway trip can catch a slow leak or impact damage early. That habit is one of the simplest ways to improve safety and tire life.

The appropriate speed for a Lexus Trucks NX300 depends on the exact tire fitted, its service description, its inflation, and its overall condition rather than the model name alone. The listed 225/65R17 product carries a 107S service description in the available information, which indicates a modern road-going radial with a defined speed category. Even so, real-world speed should always stay within the tire's rating, the vehicle manufacturer's limits, and current road conditions.

A prudent Lexus Trucks NX300 owner should avoid treating age, appearance, or brand reputation as a substitute for checking the actual tire specification. If the vehicle has an older set, a recently repaired tire, or a different size than expected, keep speeds conservative until the setup is fully evaluated. Stability, balance, and pressure all matter as much as the printed rating.
