The 2022 Lexus Trucks RX350L blends Lexus comfort and luxury crossover refinement with the added practicality of a longer three-row body, making tire choice especially important for ride quality, appearance, and everyday road manners. Owners often want to preserve that smooth touring character while making sure the tire still matches the vehicle’s wheel setup. This RX350L uses radial tires, with fitment centered on either 235/65R18 or 235/55R20 depending on configuration. The main decision is not vintage-style construction versus modern design, but confirming the correct wheel diameter first and then choosing the right tire within that size. That matters whether the goal is a clean factory-inspired look, routine road use, or replacing tires on a recently purchased vehicle.
Which Tire Size Is Right for The 2022 Lexus Trucks RX350L
Two primary tire sizes apply to the 2022 Lexus Trucks RX350L, and the first thing to confirm is wheel diameter because this vehicle uses both 18-inch and 20-inch rim fitments. Size choice also varies by sub-model, so identifying the exact RX350L configuration matters before comparing tires. Once that is settled, the decision becomes selecting the right radial tire within the correct size for appearance, road use, and wheel compatibility.
235/55R20 is a metric radial size in which 235 identifies the nominal section width in millimeters, 55 is the aspect ratio, R designates radial construction, and 20 is the rim diameter in inches. On the 2022 Lexus Trucks RX350L, this size supports a modern low-profile crossover look while keeping the tire on a 20-inch wheel. It is the size used on the Black Line Special Edition and also appears on the Base sub-model. Choosing this size starts with confirming that the vehicle actually has 20-inch wheels rather than simply matching the model name.
235/65R18 is a metric radial size where 235 is the nominal section width in millimeters, 65 is the aspect ratio, R indicates radial construction, and 18 identifies the rim diameter in inches. For the 2022 Lexus Trucks RX350L, this size keeps the same basic width as the 20-inch option but pairs it with an 18-inch wheel and a taller sidewall profile. It applies to the Base sub-model rather than the full range. This is the size to evaluate when the vehicle is equipped with 18-inch factory-style wheels or a matching replacement wheel setup.
Sub-model fitment is not completely uniform on the 2022 Lexus Trucks RX350L, so checking the exact trim matters before choosing tires. The Base can use either of the two radial sizes, while the Black Line Special Edition uses the 20-inch fitment.

Frequently Asked Questions
These FAQs focus on the exact tire sizes used on the 2022 Lexus Trucks RX350L, how fitment changes by sub-model, and what to check before replacing tires on either the 18-inch or 20-inch wheel setup.
Tire Size & Fitment
What tire size fits a 2022 Lexus Trucks RX350L?
The 2022 Lexus Trucks RX350L uses two primary tire sizes: 235/55R20 and 235/65R18. Both are radial tire sizes, but they do not use the same rim diameter, so they are tied to different wheel setups rather than being interchangeable just by model name.
The right choice depends on the exact sub-model and the wheels currently on the vehicle. A Base model may use either size, while the Black Line Special Edition uses 235/55R20. Checking the tire sidewall and confirming whether the vehicle has 18-inch or 20-inch wheels is the safest starting point before comparing replacement tires.
What size rim does a 2022 Lexus Trucks RX350L use?
A 2022 Lexus Trucks RX350L uses either an 18-inch rim or a 20-inch rim, depending on the tire size fitted to the vehicle. The 235/65R18 tire mounts on an 18-inch wheel, while the 235/55R20 tire mounts on a 20-inch wheel.
That wheel diameter needs to be confirmed before buying tires because the two RX350L fitments are built around different rim sizes. Looking at the existing tire sidewall is usually the quickest check. If the vehicle has had wheel changes, verify the actual wheel diameter on the vehicle rather than relying only on trim name or registration details.
Do all 2022 Lexus Trucks RX350L sub-models use the same tire size?
No, 2022 Lexus Trucks RX350L sub-models do not all use the same tire size. The Base sub-model can use either 235/65R18 or 235/55R20, while the Black Line Special Edition uses 235/55R20.
That means sub-model alone may not answer the whole fitment question on a Base vehicle, because wheel package still matters. The practical step is to confirm the size already installed and match it to the actual rim diameter. On a Black Line Special Edition, the tire decision is more straightforward because the fitment stays with the 20-inch setup.
Choosing the Right Tire
What should I consider when choosing a 235/55R20 tire for a 2022 Lexus Trucks RX350L?
Start by confirming that the 2022 Lexus Trucks RX350L actually uses the 235/55R20 size, since that fitment is tied to a 20-inch wheel. This size appears on the Black Line Special Edition and can also be used on the Base model when equipped with the 20-inch wheel setup.
Once size is confirmed, focus on matching the tire to the vehicle’s intended use and keeping the wheel diameter consistent. Check that all four tires match in size, inspect the condition of the wheels, and review clearance if the vehicle has non-stock wheels or suspension changes. That keeps the replacement decision centered on proper fitment rather than appearance alone.
What should I consider when choosing a 235/65R18 tire for a 2022 Lexus Trucks RX350L?
A 235/65R18 tire is appropriate for a 2022 Lexus Trucks RX350L only when the vehicle is using the 18-inch wheel setup. It is one of the two primary radial fitments for the Base sub-model, so the first step is confirming that the vehicle is not on the 20-inch package.
After confirming the 18-inch rim diameter, compare tires within that exact size and keep the vehicle’s current wheel setup in mind. Check for even tire sizing across the axle set, inspect the wheel width and wheel condition, and make sure any past modifications have not altered clearance. That helps avoid choosing a tire by model name alone when the wheel package is the real deciding factor.
How do I choose between the available tire sizes for a 2022 Lexus Trucks RX350L?
The choice between 235/55R20 and 235/65R18 is not usually a matter of preference alone on a 2022 Lexus Trucks RX350L. It depends first on which wheel diameter is on the vehicle, since one size is built for a 20-inch rim and the other is built for an 18-inch rim.
A Base model may appear with either setup, so checking the existing sidewall marking is more reliable than guessing from trim. The Black Line Special Edition uses the 20-inch fitment. If the vehicle has changed wheels since new, confirm the actual rim size and inspect for clearance before selecting tires, especially when replacing only a pair or working from an older service record.
Restoration & Appearance
Does correct tire fitment matter for a 2022 Lexus Trucks RX350L restoration or refresh?
Yes, correct tire fitment still matters on a 2022 Lexus Trucks RX350L even when the goal is a clean refresh rather than a vintage-style restoration. Because this vehicle uses either 235/65R18 or 235/55R20 depending on configuration, matching the tire to the correct wheel diameter is a basic part of preserving the intended stance and overall presentation.
Appearance and fitment work together on a luxury crossover like the RX350L. A vehicle being prepared for resale, careful ownership, or a factory-inspired look benefits from keeping the proper size for its wheel package. If wheel changes have been made, verify the actual setup first so the tire choice supports both the look of the vehicle and the way it sits in the wheel openings.
How does tire profile affect the appearance of a 2022 Lexus Trucks RX350L?
Tire profile changes the look of a 2022 Lexus Trucks RX350L because the two primary sizes pair the same nominal width with different aspect ratios and wheel diameters. The 235/55R20 presents a lower-profile look on a 20-inch wheel, while the 235/65R18 uses more sidewall on an 18-inch wheel.
That visual difference is one reason it is important to match the tire to the actual wheel setup rather than choosing by appearance alone. A Base model may use either arrangement, but the Black Line Special Edition stays with the 20-inch fitment. Keeping the intended size helps maintain a balanced look and avoids mismatching the tire profile to the wheel diameter.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2022 Lexus Trucks RX350L?
Yes, modifications can affect tire fitment on a 2022 Lexus Trucks RX350L. Wheel changes, altered wheel width or offset, suspension modifications, and ride-height changes can all influence whether the original 235/55R20 or 235/65R18 size still has proper clearance and sits correctly on the vehicle.
That is especially important on a model that already has two factory wheel diameters in use. If the RX350L has aftermarket wheels, confirm the actual rim size and inspect steering, fender, and suspension clearance before replacing tires. Checking those basics helps prevent rubbing issues and keeps the replacement centered on the real wheel setup currently on the vehicle.
What should I inspect before driving a 2022 Lexus Trucks RX350L on new tires?
Before driving a 2022 Lexus Trucks RX350L on new tires, confirm that all tires are the correct size for the wheel diameter on the vehicle and that inflation pressure is set properly. It also helps to inspect the wheels for damage and make sure the tire installation and balancing work were completed cleanly.
A short follow-up inspection is worthwhile after the first miles of driving. Look for any sign of rubbing, vibration, air loss, or uneven seating, especially if the vehicle has non-stock wheels or suspension changes. On a recently purchased RX350L, checking tread condition on the other tires and verifying that all four match in size can prevent fitment and handling problems.
How often should tires on a 2022 Lexus Trucks RX350L be inspected?
Tires on a 2022 Lexus Trucks RX350L should be inspected regularly, not only when tread appears worn. A quick visual check for uneven wear, cuts, punctures, sidewall damage, and low pressure is smart before longer trips, and a closer inspection should be part of normal service intervals throughout the year.
That routine matters whether the vehicle uses 235/65R18 or 235/55R20, because both sizes depend on maintaining proper condition and pressure for safe road use. Vehicles that sit for extended periods still need attention, since age, air loss, and sidewall deterioration can develop even with low mileage. Consistent inspection helps catch problems before they become a roadside issue.
