The 2024 Lexus Trucks TX350 brings three-row Lexus comfort into a modern crossover package, so tire choice is less about vintage-style restoration and more about matching the vehicle’s exact wheel setup. On this model, fitment centers on two radial sizes, 255/55R20 and 255/45R22, with the biggest distinction being wheel diameter and sub-model configuration. That means the first step is confirming whether your TX350 runs the 20-inch or 22-inch arrangement. Once that is settled, the decision becomes selecting the right radial size for the vehicle’s trim, appearance, and road-use needs while keeping overall fitment and wheel compatibility in check.
Which Tire Size Is Right for The 2024 Lexus Trucks TX350
The 2024 Lexus Trucks TX350 uses two primary tire sizes, and the correct choice depends on both sub-model and wheel diameter. Both fitments are radial, but one uses a 20-inch rim and the other uses a 22-inch rim, so confirming the exact wheel setup comes first before comparing tire options or planning a replacement.
255/55R20 is a metric radial size in which 255 identifies the nominal section width in millimeters, 55 is the aspect ratio, R marks radial construction, and 20 is the rim diameter in inches. On the 2024 Lexus Trucks TX350, this size is one of the primary fitments and is used on 20-inch wheels. Its role is straightforward: match the tire to the vehicle’s existing 20-inch wheel package and keep the fitment centered on the correct rim diameter. This is the size to evaluate when your TX350 is equipped with the 20-inch setup.
255/45R22 is also a metric radial size, with a 255-millimeter nominal section width, a 45-series profile, radial construction, and a 22-inch rim diameter. On the 2024 Lexus Trucks TX350, this size applies only to configurations that use the 22-inch wheel package rather than the 20-inch setup. The lower profile and larger rim diameter make wheel confirmation especially important before replacement. This is the fitment to use when the vehicle is already equipped with the 22-inch arrangement, particularly on TX350 Luxury applications that carry that wheel size.
Tire fitment on the 2024 Lexus Trucks TX350 is not identical across all covered sub-models. Checking the exact trim matters because most use the 20-inch radial size, while the Luxury trim can also appear with the 22-inch fitment.

2024 Lexus Trucks TX350 Base
The 2024 Lexus Trucks TX350 Base uses a single primary tire fitment, centered on the 20-inch radial setup. Tire selection here is mainly about replacing that size correctly and confirming the vehicle still has its original wheel diameter if any changes have been made.
The 2024 Lexus Trucks TX350 Luxury is the trim where tire fitment needs the closest attention, because it can use either the 20-inch or 22-inch radial size. Tire choice starts with verifying the wheel diameter on the vehicle, then matching the replacement tire to that exact setup.
The 2024 Lexus Trucks TX350 Premium uses the 20-inch radial fitment rather than the 22-inch option. For this trim, the main focus is confirming the existing wheel package and selecting the correct replacement size without assuming every TX350 uses the larger-diameter wheel.
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
Owners shopping tires for a 2024 Lexus Trucks TX350 usually need to sort out trim-level size differences, 20-inch versus 22-inch wheel fitment, and what to inspect before replacing tires on a modern luxury crossover.
Tire Size & Fitment
What tire size fits a 2024 Lexus Trucks TX350?
The 2024 Lexus Trucks TX350 uses two tire sizes: 255/55R20 and 255/45R22. Both are radial fitments, and the correct one depends on the exact sub-model and wheel package. Base and Premium use 255/55R20, while Luxury can use either 255/55R20 or 255/45R22.
The practical step is to confirm the wheel diameter on the vehicle before ordering a replacement. A TX350 Luxury should not be assumed to use the 22-inch size automatically, and any vehicle with replacement wheels should be checked carefully so the tire matches the actual rim and overall setup.
What size rim does a 2024 Lexus Trucks TX350 use?
A 2024 Lexus Trucks TX350 uses either a 20-inch or 22-inch rim, depending on configuration. The 255/55R20 tire is built for a 20-inch rim, and the 255/45R22 tire is built for a 22-inch rim. Both sizes are used on this model, so the wheel diameter must match the tire exactly.
That makes rim confirmation the first fitment check, especially on a used TX350 or one that may have had wheel changes. Looking only at the trim name is not always enough, because the Luxury trim can appear with more than one tire size. Reading the sidewall and measuring the installed wheel are both worthwhile.
Do all 2024 Lexus Trucks TX350 sub-models use the same tire size?
No. The 2024 Lexus Trucks TX350 Base and Premium use 255/55R20, while the Luxury trim can use either 255/55R20 or 255/45R22. That means tire fitment varies within the model line rather than staying completely uniform across every covered sub-model.
For a buyer, that changes the process from simply searching by model name to verifying the exact trim and wheel package. The safest approach is to confirm the installed size on the vehicle, then compare it against the wheel diameter already in place so the replacement tire matches the actual TX350 configuration.
Choosing the Right Tire
What should I consider when choosing a tire for a 2024 Lexus Trucks TX350?
Start with the correct size for the exact vehicle setup: 255/55R20 for the 20-inch package or 255/45R22 for the 22-inch package. Both are radial sizes, so the key decision is not construction change, but matching the tire to the trim, wheel diameter, and intended use of the vehicle.
After size is confirmed, compare the tire around everyday priorities such as ride quality, road use, and maintaining the intended overall fitment. A TX350 with non-original wheels or suspension changes deserves extra attention, because even when the model name is correct, the actual wheel-and-tire package may differ from stock.
How do I choose between the available 2024 Lexus Trucks TX350 tire sizes?
The choice is not between two interchangeable sizes. A 2024 Lexus Trucks TX350 uses 255/55R20 or 255/45R22 based on the vehicle’s actual wheel package, so the correct size is determined by the rim already on the vehicle. The 20-inch and 22-inch fitments are separate setups.
That means the decision begins at the wheel, not the tread pattern. Check the sidewall on the current tire, confirm the wheel diameter, and make sure the vehicle has not been changed from its original arrangement. Once that is settled, selecting a replacement becomes much simpler and far less likely to create fitment issues.
What rim-fitment details should I compare when choosing 2024 Lexus Trucks TX350 tires?
On a 2024 Lexus Trucks TX350, the most important rim-fitment detail is diameter. The vehicle uses either a 20-inch rim with 255/55R20 tires or a 22-inch rim with 255/45R22 tires, and those sizes are not meant to be mixed across the wrong wheel diameter.
Beyond diameter, it is smart to verify the actual wheel setup on the vehicle if anything has been changed. Replacement wheels, offset differences, or suspension modifications can affect clearance even when the size looks close on paper. Matching the tire to the installed rim package is the foundation of correct fitment on this TX350.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2024 Lexus Trucks TX350?
Yes. A 2024 Lexus Trucks TX350 that has aftermarket wheels, suspension changes, or altered ride height may no longer match its original tire-and-wheel setup. Even though the primary fitments are 255/55R20 and 255/45R22, modifications can change the clearance and wheel requirements around those sizes.
That is why it helps to inspect the vehicle itself rather than relying only on the trim name. Wheel diameter, wheel width, offset, and steering or fender clearance all deserve a look before installing replacement tires, especially if the TX350 was purchased used or has already been personalized.
What should I inspect before driving a 2024 Lexus Trucks TX350 on new tires?
Before putting a 2024 Lexus Trucks TX350 back into regular use on new tires, inspect the wheel condition, confirm the installed tire size matches the correct rim diameter, and check that inflation is set properly. It is also wise to look at alignment, suspension wear, and any signs of rubbing or uneven tire clearance.
A careful walkaround matters because tire issues are not always caused by the tire alone. Worn suspension parts, bent wheels, or an alignment problem can shorten tire life quickly and affect how the vehicle feels on the road. Catching those issues early helps the new set wear more evenly.
What should I check before a longer drive in a 2024 Lexus Trucks TX350?
Before a longer trip in a 2024 Lexus Trucks TX350, confirm that all four tires are the correct size for the vehicle’s wheel package and inspect them for cuts, punctures, bulges, or irregular wear. Checking air pressure, tread condition, and the spare or roadside plan also makes good sense before extended road use.
Longer drives put more continuous heat and load into the tires than short local trips, so small condition issues become more important. A quick review of wheel torque, visible suspension condition, and any vibration or pull noticed during recent driving can help prevent a minor problem from turning into a roadside interruption.
