The 2024 Lexus Trucks RX350h brings Lexus hybrid refinement into the modern luxury crossover market, blending quiet road manners with the everyday versatility that has made the RX such a familiar choice for premium utility buyers. On this model, tire selection is tied closely to trim level and wheel package rather than a single across-the-board fitment. The RX350h uses radial tires in either 235/60R19 or 235/50R21, depending on sub-model. That means the real decision is not just brand or tread design, but confirming whether your vehicle is on a 19-inch or 21-inch wheel before comparing replacement options for appearance, ride character, and day-to-day road use.
Which Tire Size Is Right for The 2024 Lexus Trucks RX350h
The 2024 Lexus Trucks RX350h uses two primary tire sizes, and the correct one depends on the specific sub-model and wheel package. Both are radial metric sizes, but they mount on different rim diameters, so confirming whether your RX350h has 19-inch or 21-inch wheels is the first step before choosing a replacement tire.
A 235/60R19 tire uses a 235-millimeter section width, a 60-series aspect ratio, radial construction, and a 19-inch rim diameter. On the 2024 Lexus Trucks RX350h, this size serves configurations built around the 19-inch wheel setup and keeps the fitment in a modern crossover-oriented radial format. Its dimensions place it very close in overall height to the 21-inch fitment, but the wheel diameter is different, so the two should not be treated as interchangeable without matching the wheel. This size is the one to evaluate when your RX350h is equipped with the 19-inch package.
A 235/50R21 tire keeps the same 235-millimeter nominal width but uses a lower 50-series profile on a 21-inch rim. On the 2024 Lexus Trucks RX350h, this size belongs to trims and configurations equipped with the larger wheel, giving tire choice a stronger connection to wheel confirmation than to the size code alone. The lower-profile format changes the fitment path because it requires the correct 21-inch wheel rather than simply a similar overall diameter. This is the size to compare if your RX350h Luxury or applicable Premium+ configuration carries the larger factory-style wheel setup.
Tire fitment on the 2024 Lexus Trucks RX350h varies by sub-model, and one trim can be associated with more than one wheel-and-tire combination. Identifying the exact sub-model and confirming wheel diameter will keep the tire search focused on the correct replacement size.

2024 Lexus Trucks RX350h Base
The 2024 Lexus Trucks RX350h Base uses the 235/60R19 radial tire size. Tire selection for this sub-model starts with the 19-inch wheel setup, then moves to the replacement tire that best matches your driving priorities and existing wheel configuration.
The 2024 Lexus Trucks RX350h Luxury uses the 235/50R21 radial tire size. That makes wheel diameter especially important, since replacement choices for this trim need to stay aligned with the 21-inch fitment rather than the 19-inch setup used elsewhere in the RX350h range.
The 2024 Lexus Trucks RX350h Premium uses the 235/60R19 radial tire size. For this trim, the practical job is confirming the 19-inch wheel and then comparing replacement tires within that metric radial size rather than crossing into the 21-inch fitment used on other RX350h versions.
The 2024 Lexus Trucks RX350h Premium+ can use either 235/60R19 or 235/50R21, depending on how the vehicle is equipped. This sub-model requires a closer fitment check than the others, because selecting the right tire starts with verifying which wheel diameter is actually on the vehicle.
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.
Frequently Asked Questions
RX350h buyers usually need to sort out the correct tire size by trim and wheel diameter first, then compare what that size means for replacement selection, fitment checks, and ongoing road-use maintenance.
Tire Size & Fitment
What tire size fits a 2024 Lexus Trucks RX350h?
The 2024 Lexus Trucks RX350h uses either 235/60R19 or 235/50R21, depending on sub-model and wheel setup. Base and Premium models use 235/60R19, Luxury uses 235/50R21, and Premium+ can use either size depending on configuration.
The important next step is matching the tire to the wheel actually on the vehicle. A 19-inch tire and a 21-inch tire are not interchangeable on the same wheel, even though their overall diameters are close, so checking the existing sidewall marking and wheel diameter before replacement is the safest way to stay on the correct fitment path.
What size rim does a 2024 Lexus Trucks RX350h use?
The 2024 Lexus Trucks RX350h uses either a 19-inch or 21-inch rim, depending on the tire size and sub-model. The 235/60R19 tire mounts on a 19-inch rim, while the 235/50R21 tire mounts on a 21-inch rim.
Rim diameter should be confirmed before anything else because it determines which tire size is even eligible for the vehicle. If the RX350h has been fitted with a different wheel package than expected, the installed wheel matters more than the trim name alone, so a quick visual check of the tire sidewall and wheel setup can prevent an expensive sizing mistake.
Do all 2024 Lexus Trucks RX350h sub-models use the same tire size?
No, the 2024 Lexus Trucks RX350h does not use one universal tire size across every sub-model. Base and Premium use 235/60R19, Luxury uses 235/50R21, and Premium+ may use either size depending on the wheel package on the vehicle.
That variation means trim identification helps, but wheel confirmation is still essential. Premium+ is the clearest example, because the sub-model name alone does not lock in a single size, so the current tire sidewall marking or wheel diameter should be checked before comparing replacement tires or assuming a 19-inch and 21-inch setup are interchangeable.
Choosing the Right Tire
What should I consider when choosing a tire for a 2024 Lexus Trucks RX350h?
Start with the correct size for the specific RX350h configuration: 235/60R19 or 235/50R21. Since both are radial metric sizes, the main selection factors are proper wheel diameter, the intended driving use of the vehicle, and whether the tire being considered matches the existing wheel-and-tire setup.
After size confirmation, compare replacement choices in terms of how closely they suit the vehicle’s current configuration and everyday use. It also helps to inspect the present tires for wear pattern clues, since uneven wear can point to alignment or suspension issues that should be addressed before installing new tires on a luxury crossover like the RX350h.
How do I choose between the available 235/60R19 and 235/50R21 tires for a 2024 Lexus Trucks RX350h?
The choice between 235/60R19 and 235/50R21 is not a matter of preference alone, because each size belongs to a different wheel diameter. A 2024 Lexus Trucks RX350h equipped with 19-inch wheels needs 235/60R19, while one equipped with 21-inch wheels needs 235/50R21.
Once the correct wheel size is confirmed, compare tires only within that size category. Trying to cross-shop these two fitments as though they were simple alternatives can lead to mismatch problems, so the better approach is to identify the installed wheel first and then narrow the selection to tires intended for that exact rim diameter and application.
What rim-fitment details should I compare when choosing 2024 Lexus Trucks RX350h tires?
The key rim-fitment detail on a 2024 Lexus Trucks RX350h is diameter: 19 inches for 235/60R19 and 21 inches for 235/50R21. That basic match has to be correct before any other replacement decision makes sense, since the tire bead must correspond to the wheel diameter.
It is also smart to verify the actual wheel setup on the vehicle if wheels have been changed from original-style equipment. Looking at the current sidewall size, confirming that all four wheels match, and checking for any previous modifications will give a much clearer starting point than relying only on trim level or assumption.
Restoration & Appearance
Does correct tire fitment matter for a 2024 Lexus Trucks RX350h restoration or appearance refresh?
Yes, correct tire fitment still matters even on a late-model luxury hybrid like the 2024 Lexus Trucks RX350h. The right size preserves the intended relationship between tire, wheel, and body opening, which has a direct effect on how the vehicle sits and how complete the overall presentation feels.
Appearance-focused work on a modern vehicle usually centers more on maintaining the proper wheel-and-tire proportion than on period-style sidewall details. Keeping the RX350h in its correct 19-inch or 21-inch fitment helps avoid an off-balance look, and it also reduces the chance of clearance or setup issues that can come from forcing the wrong size onto the vehicle.
How does tire size affect the appearance of a 2024 Lexus Trucks RX350h?
Tire size affects the visual balance of the 2024 Lexus Trucks RX350h because the vehicle uses two different wheel diameters with closely related overall tire heights. A 235/60R19 gives the crossover a taller sidewall on a smaller wheel, while a 235/50R21 pairs a shorter sidewall with the larger 21-inch wheel.
That means appearance is tied as much to wheel package as to tire width. Buyers trying to maintain the vehicle’s intended look should stay with the size that matches the existing wheel setup, since moving away from the correct 19-inch or 21-inch format can change the visual proportion of the RX350h even before any driving considerations come into play.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2024 Lexus Trucks RX350h?
Yes, modifications can affect tire fitment on a 2024 Lexus Trucks RX350h. Wheel changes, suspension alterations, lowering, or non-original offsets can all change how a 235/60R19 or 235/50R21 tire sits in the wheel opening and how much clearance it has during turning and suspension travel.
Even when the sidewall shows one of the correct original-size options, the actual setup still matters if the vehicle has been modified. Checking wheel diameter, wheel width, steering clearance, and tire-to-fender room before replacement helps avoid choosing a tire that matches the size code but does not suit the altered configuration.
What should I inspect before driving a 2024 Lexus Trucks RX350h on new tires?
Before driving a 2024 Lexus Trucks RX350h on new tires, inspect inflation pressure, wheel lug security, tread seating, and visible clearance around the inner fender and suspension area. It is also wise to confirm that all four tires match the intended size for the vehicle’s wheel setup.
A short follow-up inspection after the first miles of driving is worthwhile, especially if the RX350h has recently had wheels replaced or alignment work performed. Looking for rubbing marks, uneven contact, vibration, or early pressure loss can catch installation or setup issues quickly before they become harder on the tires or the vehicle.
How often should tires on a 2024 Lexus Trucks RX350h be inspected?
Tires on a 2024 Lexus Trucks RX350h should be inspected regularly rather than only when replacement time arrives. Frequent visual checks for tread wear, punctures, cuts, sidewall damage, and air-pressure loss are especially important on a luxury crossover that may see a mix of commuting, highway driving, and longer trips.
Routine inspection is also a good way to confirm that wear is even across the set. Uneven shoulder wear, feathering, or one tire losing pressure faster than the others can point to alignment, suspension, or wheel-condition issues, and finding those early helps protect whichever RX350h size the vehicle uses, whether 235/60R19 or 235/50R21.
