2014 Lexus Trucks covered a broad luxury utility range, from the body-on-frame GX460 and flagship LX570 to the more car-based RX350 and RX450h crossovers. That mix matters because Lexus used four distinct radial tire sizes across four models, with some overlap between the RX variants but model-specific sizing elsewhere. The real choice is less about old-versus-new construction and more about identifying the exact model and wheel diameter first, since these sizes span 18-, 19-, and 20-inch fitments. Before choosing a tire for 2014 Lexus Trucks, confirm whether you have a GX, LX, RX350, or RX450h and verify which wheel size is on the vehicle now.
Which Tire Size Is Right for Your 2014 Lexus Trucks
Four tire sizes are used across 2014 Lexus Trucks, and they vary by model rather than being shared across the full range. Because every size here is a radial but the fitments use different rim diameters, the first step is confirming the exact model and wheel size before narrowing down brand, sidewall, or road-use preference. Understanding that distinction before choosing a product saves time and helps ensure the right match.
Year(s): 2014|Fit(s): GX460|Construction: Radial|Rim: 18-in rim
The 265/60R18 is a metric radial size with a 265 millimeter section width, a 60-series aspect ratio, and an 18-inch rim diameter. This size is specific to the 2014 Lexus Trucks GX460 rather than universal across the full model range. It suits owners who want to stay with the GX460's original wheel diameter and focus on proper model-specific fitment for everyday luxury SUV use.
Year(s): 2014|Fit(s): LX570|Construction: Radial|Rim: 20-in rim
The 285/50R20 is a metric radial size with a 285 millimeter section width, a 50-series aspect ratio, and a 20-inch rim diameter. This size is specific to the 2014 Lexus Trucks LX570 and reflects that model's larger wheel and tire package. It is the right direction for LX570 owners who need to match the factory wheel diameter and maintain the substantial look and road-going character expected from Lexus's full-size luxury SUV.
Year(s): 2014|Fit(s): RX350, RX450h|Construction: Radial|Rim: 19-in rim
The 235/55R19 is a metric radial size with a 235 millimeter section width, a 55-series aspect ratio, and a 19-inch rim diameter. It fits the 2014 Lexus Trucks RX350 and RX450h, so it is shared within the RX portion of the model range rather than across all Lexus Trucks models. This size is the correct path for RX owners running 19-inch wheels and looking to keep the intended crossover balance of ride comfort, steering response, and original overall fitment.
Year(s): 2014|Fit(s): RX350, RX450h|Construction: Radial|Rim: 18-in rim
The 235/60R18 is a metric radial size with a 235 millimeter section width, a 60-series aspect ratio, and an 18-inch rim diameter. It also fits the 2014 Lexus Trucks RX350 and RX450h, making it another RX-specific fitment rather than a year-wide Lexus Trucks size. This is the size to follow if your RX uses 18-inch wheels, and it should be chosen by confirming the wheel diameter already on the vehicle before comparing individual tire designs.
Four Lexus Trucks models are covered for 2014. Tire size varies by model, and the RX pair can use either of two sizes depending on wheel diameter, so identifying the exact model is the first step before choosing a tire. Select a model below for model-specific fitment history and products.
2014 Lexus Trucks GX460
The GX460 was Lexus's midsize body-on-frame luxury SUV, known for combining a premium cabin with genuine off-road hardware and traditional SUV proportions. Its tires mount on 18-inch wheels in this fitment, which separates it from the larger LX and the crossover-based RX models.
The LX570 sat at the top of the Lexus SUV range in 2014, pairing full-size luxury with the rugged Land Cruiser lineage underneath. Its fitment uses a 20-inch wheel, giving it a distinct tire size compared with every other Lexus Trucks model in this year group.
The RX350 was Lexus's core luxury crossover, valued for quiet road manners, comfort, and easy everyday drivability rather than truck-based toughness. It appears with both 19-inch and 18-inch wheel fitments, so confirming which wheel is on the vehicle matters before selecting tires.
The RX450h brought hybrid power to the familiar RX luxury crossover formula, giving buyers a more efficiency-focused version of Lexus's best-known utility vehicle. Like the RX350, it uses either 19-inch or 18-inch wheel fitments depending on configuration, so wheel diameter is the key fitment check.
These FAQs focus on the model-by-model tire differences across 2014 Lexus Trucks, especially the separate GX and LX sizes and the two wheel-diameter choices used on RX350 and RX450h models.
Size Basics & Fitment
What tire sizes fit 2014 Lexus Trucks vehicles?
2014 Lexus Trucks use four tire sizes across four models: 265/60R18 for the GX460, 285/50R20 for the LX570, and either 235/55R19 or 235/60R18 for the RX350 and RX450h. Those RX sizes are shared by both RX models, while the GX460 and LX570 each use their own model-specific fitment. Rim diameters span 18, 19, and 20 inches, so these are not interchangeable across the full Lexus Trucks lineup simply by year and make.
The practical takeaway is that 2014 Lexus Trucks buyers should identify both the model and the wheel diameter before choosing a tire. A GX460 owner can go straight to 265/60R18, while an LX570 owner needs 285/50R20. RX350 and RX450h owners need one more step: verify whether the vehicle is on 18-inch or 19-inch wheels now. That check is usually faster and more reliable than guessing from trim assumptions or replacement history.
What does 265/60R18 mean on a 2014 Lexus Trucks tire?
On a 2014 Lexus Trucks GX460, 265/60R18 breaks down into four parts: 265 is the nominal section width in millimeters, 60 is the aspect ratio, R means radial construction, and 18 is the wheel diameter in inches. It is a modern metric radial format, not an older numeric or alphanumeric collector-car size. The code tells you both the tire's basic dimensions and the wheel diameter it must match.
That matters because a GX460 tire marked 265/60R18 must be paired with an 18-inch wheel, and switching to a different diameter requires a wheel change as well. For most owners, the size code is the quickest way to confirm whether the tire on the vehicle matches the intended GX460 fitment. If the sidewall shows a different diameter number, stop there and verify whether the wheels were changed at some point in the vehicle's life.
Do all 2014 Lexus Trucks models use the same tire size?
No. 2014 Lexus Trucks do not share one universal tire size across the entire model range. The GX460 uses 265/60R18, the LX570 uses 285/50R20, and the RX350 and RX450h use either 235/55R19 or 235/60R18. Every fitment in this group is radial, but the dimensions and wheel diameters differ enough that model identification is essential.
That split reflects the very different roles of these vehicles. The GX460 is a midsize body-on-frame SUV, the LX570 is a larger flagship luxury SUV, and the RX models are crossover-based. Tire selection follows those differences. If you are working from a title, registration, or a quick visual impression alone, confirm the exact model badge and wheel diameter on the vehicle before narrowing your search.
Buying the Right Tire
What brands make tires for 2014 Lexus Trucks vehicles?
Every 2014 Lexus Trucks fitment on this page uses modern radial sizing, so the relevant brand question usually comes after you have confirmed the model and wheel diameter. The GX460, LX570, RX350, and RX450h each require their own exact size, with the RX pair sharing two possible fitments depending on wheel diameter. Brand choice should always follow that first fitment decision rather than the other way around.
Once the size is confirmed, compare tire makers by the kind of driving you expect from a Lexus luxury SUV or crossover: regular road use, seasonal mileage, highway comfort, or a more touring-oriented feel. Because the RX models can appear with either 18-inch or 19-inch wheels, buyers sometimes compare brands before checking the size already on the vehicle. Reversing that order helps avoid wasted time and prevents selecting a tire that matches the model family but not the actual wheels.
How do I choose between 235/55R19 and 235/60R18 for a 2014 Lexus Trucks RX350 or RX450h?
For a 2014 Lexus Trucks RX350 or RX450h, the correct choice is determined by wheel diameter, not by swapping between constructions or eras of tire design. The 235/55R19 fits 19-inch wheels, while the 235/60R18 fits 18-inch wheels. Both are radial sizes used on RX models, and neither one is a universal upgrade or downgrade for the other without changing the wheel itself.
Start by reading the tire sidewall or measuring the wheel diameter already on the vehicle. If the RX is on 19-inch wheels, stay with 235/55R19; if it is on 18-inch wheels, stay with 235/60R18. Owners restoring appearance after a wheel swap should decide whether they want to keep the current wheel package or return to the original wheel diameter for that specific RX configuration before choosing a tire.
Is the larger 285/50R20 the right upgrade for a 2014 Lexus Trucks GX460 or RX model?
No, the 285/50R20 is the fitment used for the 2014 Lexus Trucks LX570, not a general upgrade size for the GX460, RX350, or RX450h. That size is built around a 20-inch wheel and a different dimensional profile than the 18-inch and 19-inch fitments used elsewhere in the Lexus Trucks range. Moving to it would require more than a tire change and should not be treated as a simple same-year substitution.
If your goal is appearance, always work from the wheel diameter and original application first. The LX570's larger tire package suits that model's full-size proportions, while the GX460 and RX models were fitted around different wheel-and-tire combinations. Cross-model size swaps can affect clearance, speedometer behavior, and overall driving character. Staying with the correct model-specific size is the safest starting point unless a specialist has planned a complete wheel-and-tire conversion.
Fitting & Setup
What rim width do 2014 Lexus Trucks tires require?
2014 Lexus Trucks use tires that mount on three different rim diameters across the model range: 18-inch, 19-inch, and 20-inch wheels. The GX460 uses 265/60R18, the LX570 uses 285/50R20, and the RX350 and RX450h use either 235/60R18 or 235/55R19. Rim width still matters within each of those diameters, but the first fitment check is matching the tire to the correct wheel diameter for the specific model.
When replacing tires, verify the wheel size stamped on the wheel or shown on the current tire sidewall before comparing brand or tread design. If the vehicle has aftermarket wheels, that step becomes even more important. A tire can share the same section width as another option and still be wrong if the rim diameter differs. Once the correct diameter is confirmed, the exact tire's fitment details should be checked against the wheel on the vehicle.
Do 2014 Lexus Trucks tires require inner tubes?
2014 Lexus Trucks use modern radial metric sizes, and fitments of this type are ordinarily matched with tubeless tire-and-wheel systems rather than vintage tube-type arrangements. The GX460, LX570, RX350, and RX450h all fall into that modern SUV and crossover era, with sizes such as 265/60R18, 285/50R20, 235/55R19, and 235/60R18. Tube use is generally tied to wheel design or a specific tire construction, not to these Lexus model-year fitments as a class.
The smart check is the actual wheel and the sidewall marking on the tire you plan to use. If the vehicle still wears its factory-style late-model wheels, tubeless service is the normal expectation. If a wheel has been changed, repaired, or refinished, confirm that it is suitable for the tire being mounted and that the valve hardware matches the wheel design. A tire shop familiar with late-model OE and aftermarket wheels can verify that quickly.
Maintenance, Storage & Longevity
How should I store a 2014 Lexus Trucks when the tires are fitted?
A 2014 Lexus Trucks should be stored in a cool, dry, dark space away from direct sunlight, electric motors, battery chargers, welders, and other ozone-producing equipment that can accelerate rubber aging. Keep the tires at proper pressure, avoid prolonged contact with standing moisture, and move the vehicle periodically if it will sit for long stretches. These are all radial fitments, so they generally tolerate storage better than older bias-ply tires, but age and environment still matter.
For seasonal or collector-style use, wash road salts and grime off the tires before storage and keep the vehicle out of intense heat whenever possible. If the Lexus will sit for months, rolling it occasionally helps prevent flat spotting and keeps the casing from resting on one contact patch too long. Owners storing a GX460, LX570, RX350, or RX450h for extended periods often benefit from checking pressure monthly rather than waiting until the next drive.
How long do tires on a 2014 Lexus Trucks typically last?
On a 2014 Lexus Trucks, tire age is usually a more useful guide than mileage alone, especially if the vehicle sees moderate or occasional use. A good rule is to begin evaluating tires closely once they reach about five to seven years of age and to treat ten years as a serious replacement consideration regardless of tread depth. The DOT date code on the sidewall tells you when the tire was manufactured.
That approach matters because a luxury SUV or crossover can accumulate relatively low miles while the rubber still hardens and the internal structure continues to age. A tire that looks acceptable at first glance may still be too old for confident road use. Check the date code, inspect for cracking or deformation, and treat age as part of the decision even if your GX460, LX570, RX350, or RX450h is driven only on weekends or short local trips.
How often should tires on a 2014 Lexus Trucks be inspected?
Tires on a 2014 Lexus Trucks should be inspected before every drive and given a more deliberate check before any extended highway trip. Look for sidewall cracking, cuts, bulges, punctures, irregular wear, and signs of pressure loss. Because these are modern radial SUV and crossover sizes, even a small pressure mismatch can affect ride quality, steering feel, and tread wear more quickly than many owners expect.
For regular use, a quick walkaround and pressure check goes a long way. For longer drives, inspect the spare as well and make sure it is usable, properly inflated, and age-appropriate. GX460 and LX570 owners should also look closely after off-pavement use, while RX350 and RX450h owners should watch for shoulder wear that can point to alignment or inflation issues. Catching those signs early usually saves both tire life and roadside inconvenience.
Safety & Road Use
Are 2014 Lexus Trucks tires safe for highway driving?
Yes, 2014 Lexus Trucks use modern radial tire sizes that are intended for contemporary road use when the tires are the correct size, in good condition, and properly inflated. The GX460, LX570, RX350, and RX450h all rely on metric radial fitments rather than vintage bias-ply constructions, so highway use is a normal part of their design context. Safety still depends on age, wear, damage, and whether the tire actually matches the wheel and vehicle application.
The important distinction is between a fresh, correctly fitted tire and an old or mismatched one. Before highway travel, check age, tread condition, visible cracking, and inflation pressure, and make sure the sidewall size matches the wheel diameter on the vehicle. On a modern Lexus SUV or crossover, suspension condition, alignment, brakes, and load management can affect highway confidence just as much as the tire itself. Treat the tire as one part of the whole system.
What inflation pressure should I use for 2014 Lexus Trucks tires?
Inflation pressure for 2014 Lexus Trucks should follow the vehicle manufacturer's recommendation for the exact model and wheel package, not a one-size-fits-all number carried over from another Lexus model or another tire size. That matters because the GX460, LX570, RX350, and RX450h do not all use the same dimensions. Even the RX350 and RX450h can use either 18-inch or 19-inch fitments, which should be treated according to the vehicle's intended setup.
Use the tire placard, owner's manual, or original Lexus service information as the starting point, then compare that with the tire maker's guidance for the exact product you choose. Do not assume that a pressure suitable for a 235/60R18 RX tire is also correct for a 285/50R20 LX570 tire. Pressure affects ride, tread wear, and load behavior, so matching the recommendation to the actual size and model is essential.
What should I check before taking a 2014 Lexus Trucks on a longer drive?
Before a longer drive in a 2014 Lexus Trucks, inspect each tire for cracking, cuts, bulges, punctures, uneven wear, and proper cold inflation pressure. Confirm that the size on the sidewall matches the model and wheel diameter: 265/60R18 for GX460, 285/50R20 for LX570, and either 235/55R19 or 235/60R18 for RX350 and RX450h depending on wheel fitment. Check the spare as well, especially if it has aged in place for years.
Tires are only one part of the pre-trip picture on a luxury SUV or crossover, so include brakes, fluids, suspension feel, lights, and battery condition in the same inspection. If the vehicle has recently sat unused, drive it locally first to catch vibration, pulling, or a slow leak before committing to a longer route. Verifying the basics ahead of time is especially worthwhile on older-used examples whose maintenance history may not be fully known.
