2019 Lexus Trucks Tire Fitment Guide

2019 Lexus Trucks vehicles use 10 different tire sizes across the full lineup: 265/60R18 for GX460; 275/50R21 and 285/50R20 for LX570; 225/60R18, 225/65R17, 235/55R18, and 235/50R19 for NX300; 225/60R18 and 225/65R17 for NX300h; 235/55R20 and 235/65R18 for RX350, RX350L, RX450h, and RX450hL; and 225/50R18 for UX200 and UX250h. Every fitment is radial, but rim diameters range from 17 to 21 inches.

That spread means year and make are only the starting point for 2019 Lexus Trucks tire selection. The next step is matching the exact model and then confirming the wheel diameter already on the vehicle, especially on NX, RX, and LX models that can use more than one size depending on wheel package.

On a 2019 Lexus Trucks tire, 225/65R17 means the tire is 225 millimeters wide, has a 65-series aspect ratio, uses radial construction, and fits a 17-inch wheel. That size appears on the NX300 and NX300h. The available example in this size carries an S speed rating, which is rated to 112 mph, and a maximum load of 2,150 pounds at 65 psi.

The practical point is that 225/65R17 is more than just a code on the sidewall; it defines width, profile, construction, and wheel diameter all at once. If a 2019 Lexus Trucks owner is moving between trim levels or replacing one damaged tire, matching all four parts of the size code is essential before comparing tread style or brand.

No, 2019 Lexus Trucks models do not use the same tire size. GX460 has one 18-inch fitment, LX570 uses either a 20-inch or 21-inch fitment, NX300 spans four sizes across 17-inch, 18-inch, and 19-inch wheels, NX300h uses two sizes, the RX family shares two sizes, and the UX pair shares one 18-inch size. The lineup covers compact crossovers through full-size SUVs, so the tire sizing reflects those differences.

That variation matters because two Lexus utility models from the same year can look similar at a glance but still require very different tires. A buyer comparing 2019 Lexus Trucks tires should identify the exact model first, then verify the wheel diameter on the vehicle, and only after that compare brand, sidewall, or tread options.

Current 2019 Lexus Trucks product coverage includes two sidewall styles in the sizes represented here. The 225/65R17 uses an RBL sidewall on the BFGoodrich All-Terrain T/A KO2, while the 225/50R18 uses Blackwall styling across the BFGoodrich g-Force options. Both are radial tires, but the sidewall appearance aligns with very different tire personalities.

For a 2019 Lexus Trucks owner, sidewall style is usually a visual and use-case choice rather than a fitment shortcut. Blackwall designs suit modern crossover appearance well, while an RBL all-terrain sidewall gives a more rugged look on an NX. If sidewall appearance matters, compare that detail alongside size and tread type before settling on a tire.

BFGoodrich is the brand represented in the current 2019 Lexus Trucks product range shown here. It covers the 225/65R17 size with the All-Terrain T/A KO2 and the 225/50R18 size with g-Force street-oriented choices including the COMP-2 A/S, Sport COMP-2, and Phenom T/A. All of those are radial tires, but they serve different driving profiles within their respective sizes.

That means brand choice is narrower than size choice on this page, especially because most 2019 Lexus Trucks fitments are tied to model-specific wheel diameters. Once the correct size is confirmed, the remaining comparison is usually between tire character and sidewall presentation rather than simply choosing among many different brands in the same fitment.

For 2019 Lexus Trucks in 225/50R18, both BFGoodrich g-Force COMP-2 A/S and g-Force Sport COMP-2 are Blackwall radial tires that fit 18-inch wheels and work with 6.0- to 8.0-inch rim widths. Both use the same 225/50ZR18 sizing and carry a W speed rating to 168 mph. The main spec difference here is weight, with the COMP-2 A/S at 28 pounds and the Sport COMP-2 at 27 pounds.

That makes them closely matched on fitment and speed capability, so the decision comes down more to the specific series character than to any major dimensional change. A 2019 Lexus Trucks owner choosing between them should keep the size fixed at 225/50R18 and then compare the intended use of each series rather than expecting one to change wheel compatibility.

Rim width guidance is available for two 2019 Lexus Trucks sizes here. The 225/65R17 fits a 6.0- to 8.0-inch rim width range, and the 225/50R18 products also fit 6.0- to 8.0-inch rim widths. Other 2019 Lexus Trucks sizes on this page still need to be matched to the exact tire and wheel combination being used.

Rim width matters because the same diameter wheel can still be too narrow or too wide for a given tire section width. If a 2019 Lexus Trucks owner is replacing tires on original wheels, that range is a useful checkpoint; if the vehicle has aftermarket wheels, verifying width before tire selection becomes even more important.

The 2019 Lexus Trucks products represented here are modern radial fitments without tube-type markings, so they should be treated as tubeless unless a specific wheel condition calls for a different approach. No TT markings appear in the current 225/65R17 or 225/50R18 product coverage. The key point is to match the tire to a sound wheel designed for tubeless service.

For most 2019 Lexus Trucks owners, that means tube fitment is not the primary concern; wheel integrity, bead condition, and valve stem condition matter more. If a wheel has corrosion, prior damage, or an uncertain repair history, it is worth having the wheel inspected before mounting a new tire, even when the size itself is correct.

A 2019 Lexus Trucks should be stored away from direct sunlight, standing moisture, and ozone sources such as electric motors, welders, and battery chargers. Keeping the tires clean, properly inflated, and out of long-term heat exposure helps slow age-related rubber degradation. Periodic movement is also helpful so the tires do not sit in one loaded position for months at a time.

For owners who store a 2019 Lexus Trucks seasonally, a cool enclosed space is usually better than a bright garage bay or outdoor cover. If the vehicle will sit for an extended period, check pressure before storage and again before returning it to service, since even modern radial tires can develop issues when neglected during long idle periods.

Tires on a 2019 Lexus Trucks should be judged by age as well as tread depth. A common collector and enthusiast guideline is to begin close inspection in the five- to seven-year range and to treat around 10 years as a serious replacement point, even if the tread still looks usable. The DOT date code on the sidewall is the starting point for that timeline.

That matters because many Lexus utility models see relatively low annual mileage, which can make old tires look healthier than they really are. A 2019 Lexus Trucks owner should not rely on mileage alone; sidewall condition, stored history, and manufacture date are often more revealing than tread wear when deciding whether to keep or replace a set.

Tires on a 2019 Lexus Trucks should be inspected before every drive and more carefully before any longer highway outing. Look for cracking, cuts, bulges, irregular tread wear, punctures, and pressure loss, and include the valve stems in the inspection routine. On vehicles driven infrequently, those checks matter even more because age and storage can affect the tires between trips.

A quick walkaround catches many problems before they become roadside issues. For a 2019 Lexus Trucks that spends long periods parked, monthly pressure checks and a hands-on sidewall inspection are a sensible routine, especially if the vehicle is carrying family passengers or will be used for a longer road trip rather than short local driving.

2019 Lexus Trucks use modern radial tire sizes, and the products represented here carry road-use speed ratings appropriate to normal highway operation. The 225/65R17 example is rated S, or 112 mph, while the 225/50R18 examples are rated W, or 168 mph. Those figures are well beyond ordinary U.S. highway speeds, provided the tires are in good condition and correctly inflated.

Real-world safety depends on more than the letter rating alone. A 2019 Lexus Trucks owner should also consider tire age, pressure, alignment, suspension condition, and whether all four tires are properly matched. On a modern luxury SUV or crossover, those basics usually matter more in day-to-day driving than the raw speed ceiling printed on the sidewall.

Inflation pressure on 2019 Lexus Trucks should follow the vehicle placard or owner's manual first, because factory pressure targets are vehicle-specific and not interchangeable between GX, LX, NX, RX, and UX models. One tire on this page, the 225/65R17 BFGoodrich All-Terrain T/A KO2, carries a maximum load of 2,150 pounds at 65 psi, while the 225/50R18 BFGoodrich Phenom T/A shows 1,709 pounds at 50 psi. Those figures are tire ratings, not blanket recommended operating pressures for every model.

The practical takeaway is to avoid transferring a pressure number from one 2019 Lexus Trucks tire size to another just because both are radial tires. Start with the vehicle's factory specification, then compare it with the tire maker's load and pressure information if you are changing tire type or replacing the original style with a different service category.

Before a longer trip in a 2019 Lexus Trucks, inspect each tire for sidewall cracking, cuts, punctures, tread depth, uneven wear, and any bulging or vibration concerns that have shown up in recent driving. Check cold inflation pressure, confirm the spare is usable, and make sure the valve stems are in good condition. If the vehicle has been parked for an extended period, add a close inspection for age-related hardening or weathering.

Tires are only one part of a longer-drive checklist, but they are the part in constant contact with the road. A 2019 Lexus Trucks owner should also think in terms of overall readiness: brakes, fluids, lights, and suspension condition all support the tire's ability to do its job, especially on heavier SUVs such as the GX460 and LX570.
