The 2025 Lexus Trucks TX350 brings Lexus comfort and three-row crossover utility into a modern luxury SUV format, so tire fitment matters as much for ride quality and road manners as it does for appearance. On this exact model, the key fitment decision starts with wheel size, because the TX350 uses either 255/55R20 or 255/45R22 radial tires depending on sub-model. That means some owners will be choosing around a 20-inch setup, while others need to match a 22-inch package. Before comparing replacement tires, confirm the exact trim and wheel diameter so the tire selected suits the vehicle’s original stance, intended use, and overall fitment.
Which Tire Size Is Right for The 2025 Lexus Trucks TX350
The 2025 Lexus Trucks TX350 uses two primary tire sizes, and the correct one depends on the specific sub-model and wheel package. Both sizes are radial, but they mount on different rim diameters, so the first step is confirming whether the vehicle has the 20-inch or 22-inch wheel setup before choosing a replacement tire.
255/55R20 is a metric radial size that uses a 255-millimeter nominal section width, a 55-series aspect ratio, and a 20-inch rim diameter. On the 2025 Lexus Trucks TX350, this size is part of the primary fitment for several sub-models and reflects a modern radial construction suited to current SUV ride and handling expectations. Its dimensions make it a key fitment reference for owners replacing tires on the 20-inch wheel package. The practical priority is matching the existing wheel diameter and confirming the vehicle has not been changed to a different wheel setup since new.
255/45R22 is a metric radial size with a 255-millimeter nominal section width, a 45-series profile, and a 22-inch rim diameter. For the 2025 Lexus Trucks TX350, this size belongs to sub-models equipped with the larger 22-inch wheel package, so it serves a different fitment role than the 20-inch option even though the section width is the same. The lower-profile format changes the tire selection process by tying it directly to the larger rim diameter. Buyers should verify the actual wheels on the vehicle before replacing tires, especially if the SUV has seen trim upgrades or wheel changes.
Sub-model fitment matters on the 2025 Lexus Trucks TX350 because tire size changes with wheel package. Some trims stay with one size, while the Luxury trim can use either setup, so confirming the exact sub-model and wheel diameter is the first step before selecting tires.

2025 Lexus Trucks TX350 Base
The 2025 Lexus Trucks TX350 Base uses the 255/55R20 radial tire size on a 20-inch wheel package. Tire selection for this trim starts with keeping that 20-inch fitment intact and then confirming the wheels on the vehicle are still the original diameter.
The 2025 Lexus Trucks TX350 F Sport Handling uses the 255/45R22 radial size, tying it to the larger 22-inch wheel setup. That makes wheel confirmation especially important before replacement, since a 20-inch tire choice would not suit this configuration.
The 2025 Lexus Trucks TX350 Luxury can use either 255/45R22 or 255/55R20, so this trim requires an extra fitment check before ordering tires. Selection depends on the actual wheels installed on the vehicle, not the trim name alone.
The 2025 Lexus Trucks TX350 Premium uses the 255/55R20 radial size with the 20-inch wheel package. For this trim, the tire decision is straightforward as long as the vehicle still carries the correct wheel diameter and has not been converted to a different setup.
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
Common questions for the 2025 Lexus Trucks TX350 usually center on identifying the correct tire size by sub-model, confirming 20-inch versus 22-inch wheel fitment, and understanding what to inspect before replacing or driving on a new set of tires.
Tire Size & Fitment
What tire size fits a 2025 Lexus Trucks TX350?
The 2025 Lexus Trucks TX350 uses either 255/55R20 or 255/45R22 tires, depending on sub-model and wheel package. Base and Premium models use 255/55R20, F Sport Handling uses 255/45R22, and Luxury models can use either size.
The most important step is confirming the exact trim and the wheels currently on the vehicle. Because the two sizes use different rim diameters, choosing the correct tire starts with verifying whether the TX350 has 20-inch or 22-inch wheels rather than assuming every trim uses the same setup.
What size rim does a 2025 Lexus Trucks TX350 use?
A 2025 Lexus Trucks TX350 uses either a 20-inch or 22-inch rim, depending on the tire size and sub-model. The 255/55R20 fitment corresponds to a 20-inch rim, while the 255/45R22 fitment corresponds to a 22-inch rim.
Rim diameter needs to match the tire size exactly, so this is not a detail to estimate by appearance alone. Checking the sidewall of the current tires and confirming the actual wheel package on the vehicle will prevent ordering a 20-inch tire for a 22-inch wheel, or the reverse.
Do all 2025 Lexus Trucks TX350 sub-models use the same tire size?
No, not all 2025 Lexus Trucks TX350 sub-models use the same tire size. Base and Premium use 255/55R20, F Sport Handling uses 255/45R22, and Luxury can be equipped with either of those two sizes.
That variation means the trim badge alone is not always enough, especially on a Luxury model. A quick check of the existing tire sidewall or wheel diameter is the safest way to confirm fitment before replacement, particularly if the vehicle has had wheels changed or upgraded since it was first delivered.
Choosing the Right Tire
What should I consider when choosing a tire for a 2025 Lexus Trucks TX350?
Start with the correct primary size for the exact 2025 Lexus Trucks TX350 sub-model: 255/55R20 or 255/45R22. From there, the main considerations are matching the existing wheel diameter, keeping the proper size format, and choosing a tire that suits how the SUV is actually driven.
Practical checks matter just as much as the size itself. Verify the wheels currently on the vehicle, look for any aftermarket changes, and compare the condition of the existing setup before replacement. That approach helps preserve proper fitment while keeping ride quality, appearance, and everyday drivability in line with the TX350’s intended character.
How do I choose between the available 2025 Lexus Trucks TX350 tire sizes?
The two available tire sizes are not alternatives to choose freely across every 2025 Lexus Trucks TX350. They are tied to different wheel diameters and sub-model applications, so the correct choice comes from the vehicle’s actual setup rather than personal preference alone.
A Base or Premium model points toward 255/55R20, while an F Sport Handling model points toward 255/45R22. Luxury requires a closer check because it may have either package. Reading the current sidewall and confirming the wheel diameter will answer the question faster than relying on trim assumptions or visual guesswork.
What rim-fitment details should I compare when choosing 2025 Lexus Trucks TX350 tires?
The main rim-fitment detail is diameter, since the 2025 Lexus Trucks TX350 uses either a 20-inch or 22-inch wheel depending on configuration. A 255/55R20 tire belongs on a 20-inch rim, and a 255/45R22 tire belongs on a 22-inch rim.
Wheel changes can complicate replacement, especially on used vehicles or trims that may have been upgraded cosmetically. Along with diameter, inspect the overall wheel setup and make sure the replacement tire matches the actual hardware on the SUV. That simple check helps avoid mounting problems and keeps fitment consistent with the vehicle’s current configuration.
Restoration & Appearance
Does correct tire fitment matter for a 2025 Lexus Trucks TX350 restoration or appearance refresh?
Yes, correct tire fitment matters even on a newer luxury SUV like the 2025 Lexus Trucks TX350. The right tire size preserves the intended relationship between wheel diameter, sidewall profile, and overall stance, whether the vehicle uses the 20-inch or 22-inch setup.
Appearance can change noticeably when the wrong size is installed, even if the difference seems small on paper. Matching the tire to the actual wheel package helps the vehicle keep a balanced look while avoiding avoidable fitment issues. That is especially important on trims where wheel design is part of the visual character.
Which tire setup best preserves the intended look of a 2025 Lexus Trucks TX350?
The setup that best preserves the intended look of a 2025 Lexus Trucks TX350 is the size that matches its original wheel diameter and trim-specific package. That means keeping 255/55R20 on 20-inch applications and 255/45R22 on 22-inch applications unless the vehicle has been intentionally reconfigured.
Maintaining the correct profile is important because both sizes share the same overall diameter while presenting differently through wheel and sidewall proportions. Checking what is currently installed prevents a mismatch that can alter the SUV’s visual balance. On Luxury models, that verification is especially important because either wheel package may be present.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2025 Lexus Trucks TX350?
Yes, modifications can affect tire fitment on a 2025 Lexus Trucks TX350. Wheel changes, suspension lowering, altered offsets, and other aftermarket adjustments can change the clearances that the original 255/55R20 or 255/45R22 setup was designed to work with.
That matters because a tire that matches the factory size still needs to work with the actual wheels and suspension now on the vehicle. Checking steering clearance, fender room, and wheel diameter before replacement is a smart step whenever the TX350 has been personalized beyond its original trim configuration.
What should I inspect before driving a 2025 Lexus Trucks TX350 on new tires?
Before driving a 2025 Lexus Trucks TX350 on new tires, inspect the wheel diameter, confirm the installed size matches the vehicle’s setup, and look over the wheels for damage or irregular wear signs. It also helps to check that the tires are properly seated and inflated for initial road use.
A short visual inspection after installation can catch issues early. Look for sidewall damage, uneven spacing to suspension or body components, and any sign of rubbing during low-speed steering. That quick check is especially worthwhile on vehicles with 22-inch wheels or any history of wheel, brake, or suspension changes.
What should I check before a longer drive in a 2025 Lexus Trucks TX350?
Before a longer drive in a 2025 Lexus Trucks TX350, confirm that all four tires are the correct size for the vehicle’s wheel package and inspect them for cuts, bulges, cracking, uneven wear, or signs of air loss. Tire pressure should also be checked while the tires are cold.
Longer trips put more importance on consistency across the whole set. Make sure the TX350 is not running a mixed 20-inch and 22-inch arrangement, verify the spare or temporary plan if applicable, and pay attention to any vibration or clearance issue during the first miles after service or wheel replacement.
