The 2023 Lexus Trucks RZ450e brings Lexus into the fully electric luxury crossover market with a design and driving character that place as much emphasis on refinement as modern technology. For tire selection, that matters because this model uses staggered front and rear sizing, with 20-inch fitments paired as 235/50R20 front and 255/45R20 rear, while Premium models may also use an 18-inch staggered setup with 235/60R18 front and 255/55R18 rear. All primary fitments are radial. The choice is less about bias-ply versus radial and more about matching the exact wheel package, sidewall style, and tire series to the vehicle's trim, appearance goals, and current wheel setup.
Which Tire Size Is Right for The 2023 Lexus Trucks RZ450e
Four primary tire sizes apply to the 2023 Lexus Trucks RZ450e, and the correct choice depends first on whether the vehicle has the 20-inch or 18-inch wheel package and whether you are selecting for the front or rear axle. This is a staggered-fitment vehicle, so front and rear sizes are not interchangeable. Before choosing a tire, confirm the exact sub-model position and the wheel diameter currently on the vehicle.
A 255/45R20 tire uses a 255-millimeter nominal section width, a 45-series profile, radial construction, and a 20-inch rim diameter. On the 2023 Lexus Trucks RZ450e, this is a rear fitment for 20-inch staggered applications, so it should be paired correctly with the matching front size rather than selected in isolation. Available choices in this size include BFGoodrich, Nitto, and Pro-Trac, with sidewall treatments such as Blackwall, raised white letter, and Redline across several tire series. That makes this size especially relevant for owners balancing appearance, brand preference, and the vehicle's existing rear wheel setup.
In 255/55R18, the 255 refers to nominal width in millimeters, the 55 is the aspect ratio, the R marks radial construction, and the 18 denotes an 18-inch rim. On the 2023 Lexus Trucks RZ450e, this is used as a rear tire in the 18-inch staggered arrangement found on certain Premium configurations. That means it is tied to both wheel diameter and axle location, not simply to model year and make alone. It should be evaluated as part of the complete 18-inch front-and-rear combination, especially if the vehicle has seen wheel changes or trim-level variations.
Sub-model fitment on the 2023 Lexus Trucks RZ450e varies by trim, wheel package, and axle position. Checking the exact Front or Rear application matters because this model uses staggered sizing, and Premium models may be equipped with either 20-inch or 18-inch combinations.

2023 Lexus Trucks RZ450e Luxury Front
The Luxury Front application uses a 20-inch radial front tire size, making it part of the model's 20-inch staggered arrangement. Tire selection here should stay focused on the front position and on matching the existing wheel package rather than treating it as an all-around fitment.
The Luxury Rear application uses the wider 20-inch rear radial size that completes the staggered setup on this trim. That makes rear tire choice dependent on keeping the correct front-to-rear pairing and confirming that the vehicle still carries its original 20-inch wheel configuration.
The Premium Front application can use either a 20-inch or 18-inch front radial size, depending on the wheel package installed on the vehicle. The key step is confirming wheel diameter first, since that determines which front tire size belongs on the vehicle.
The Premium Rear application also varies between 20-inch and 18-inch rear radial sizes, tied to the corresponding staggered wheel package. Rear tire selection should follow the actual wheel diameter on the vehicle and stay matched to the correct front-and-rear combination.
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.

Tire Size & Fitment
What tire size fits a 2023 Lexus Trucks RZ450e?
The 2023 Lexus Trucks RZ450e uses four primary tire sizes across its covered configurations: 235/50R20, 255/45R20, 235/60R18, and 255/55R18. These are all radial sizes, and they are used in staggered front-and-rear combinations rather than as a single size for all four corners.
The first step is confirming whether the vehicle has the 20-inch or 18-inch wheel package and whether the tire being replaced is on the front or rear axle. Premium models can use either wheel diameter, so checking the actual wheel on the vehicle matters more than assuming one size applies to every RZ450e.
What size rim does a 2023 Lexus Trucks RZ450e use?
The 2023 Lexus Trucks RZ450e uses either an 18-inch or 20-inch rim, depending on configuration. The 235/50R20 and 255/45R20 sizes mount on 20-inch wheels, while the 235/60R18 and 255/55R18 sizes mount on 18-inch wheels.
Rim diameter should be verified before any tire purchase because this model also uses staggered sizing from front to rear. A front tire may share the same wheel diameter as the rear, but it does not share the same width or size code, so both axle position and rim size need to be checked together.
Why does the 2023 Lexus Trucks RZ450e have more than one tire size?
More than one tire size appears on the 2023 Lexus Trucks RZ450e because the model uses staggered front-and-rear fitment and can also be equipped with either an 18-inch or 20-inch wheel package. That creates one pair of sizes for 20-inch applications and another pair for 18-inch applications.
This means tire selection is not just a year-make-model question. The owner needs to identify the trim and wheel package, then confirm whether the replacement is for the front or rear axle. On Premium models especially, that extra step prevents mixing 18-inch and 20-inch fitments or ordering the correct diameter for the wrong position.
Choosing the Right Tire
What should I consider when choosing a 255/45R20 tire for a 2023 Lexus Trucks RZ450e?
Start with the basics: 255/45R20 is a rear radial size used on 20-inch staggered applications for the 2023 Lexus Trucks RZ450e. Once that fitment is confirmed, the comparison shifts to brand, tire series, sidewall treatment, and any specification differences such as rim-width range, load figure, or tire weight where those details are available.
Appearance can matter here just as much as the size itself, since Blackwall, raised white letter, and Redline versions are available. It also helps to compare the tire against the wheel already on the vehicle, especially if the RZ450e has been modified or if only one rear tire is being replaced and visual consistency matters.
What sidewall styles are available for 2023 Lexus Trucks RZ450e tires?
For the available 255/45R20 fitment choices on the 2023 Lexus Trucks RZ450e, sidewall styles include Blackwall, raised white letter, and Redline. Those options create noticeably different visual presentations even when the basic tire size remains the same.
A Blackwall tire keeps the look understated and contemporary, while raised white letter and Redline versions add more visual character. The main thing is to keep appearance decisions secondary to correct fitment, since the RZ450e still requires the proper rear size and wheel diameter before sidewall style becomes a meaningful choice.
What brands offer tires for the 2023 Lexus Trucks RZ450e?
In the available 255/45R20 fitment, brands include BFGoodrich, Nitto, and Pro-Trac. Those options appear across several tire series, giving the 2023 Lexus Trucks RZ450e owner a range of choices within the correct rear 20-inch size.
Brand alone should not be the only deciding factor. It makes more sense to compare the exact tire series, sidewall style, and wheel compatibility details that matter for the vehicle's setup and the owner's appearance goals. That is especially true on a staggered vehicle, where keeping the correct rear size takes priority over broad brand preference.
Restoration & Appearance
How does tire construction affect the appearance of a restored 2023 Lexus Trucks RZ450e?
Tire construction is less of a visual dividing line on a 2023 Lexus Trucks RZ450e than it would be on an older collector vehicle because the primary fitments are already modern radial sizes. The more noticeable appearance difference comes from the sidewall treatment and the overall character of the tire series chosen in the correct size.
A Blackwall tire tends to preserve a clean contemporary look, while raised white letter or Redline styling creates a more customized presentation. For an owner focused on preserving the vehicle's intended design language, choosing the correct staggered size and wheel diameter first is still more important than any visual sidewall detail.
Does correct tire fitment matter for a 2023 Lexus Trucks RZ450e restoration or appearance-focused build?
Correct tire fitment matters because the 2023 Lexus Trucks RZ450e uses staggered front and rear sizing and may use either 18-inch or 20-inch wheels depending on configuration. An appearance-focused build can still miss the mark if the tire diameter or axle position is wrong, even when the sidewall style looks appealing.
The best starting point is matching the actual wheel package on the vehicle and preserving the proper front-to-rear relationship. Once those basics are right, the owner can compare details such as Blackwall, raised white letter, or Redline styling to shape the final look without drifting away from the vehicle's correct fitment pattern.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2023 Lexus Trucks RZ450e?
Yes, modifications can affect tire fitment on a 2023 Lexus Trucks RZ450e. Aftermarket wheels, changes in wheel width or offset, suspension alterations, and body modifications can all change how a tire fits, even when the size code looks close to the original front or rear specification.
That matters even more on this vehicle because it uses staggered sizing and more than one wheel diameter. A modified RZ450e should be checked for wheel diameter, axle position, inner clearance, outer fender space, and steering clearance before replacement tires are chosen, especially if the current setup no longer matches the original trim-level wheel package.
What should I inspect before driving a 2023 Lexus Trucks RZ450e on new tires?
Before regular road use, inspect the tire size, wheel diameter, and front-versus-rear placement to make sure the staggered setup is correct. Then check inflation pressure, valve stems, tread and sidewall condition, and look for any rubbing or clearance issues once the tires are mounted.
A short initial drive can help reveal vibration, pulling, or contact problems that are easier to correct early. It also helps to recheck pressure after installation and confirm that each tire matches the intended axle position, since mixing up front and rear sizes on a staggered RZ450e can create avoidable fitment and handling issues.
How often should tires on a 2023 Lexus Trucks RZ450e be inspected?
Tires on a 2023 Lexus Trucks RZ450e should be inspected regularly, not just when tread appears worn. A practical routine is to check them before longer drives and at normal service intervals, looking for air loss, uneven wear, cuts, bulges, and sidewall damage.
Regular inspections are especially useful on a staggered setup because front and rear tires do different jobs and may not wear the same way. Owners should also keep an eye on wheel condition and any signs of rubbing after impacts, wheel changes, or suspension work, since those issues can affect fitment long before a tire is visibly worn out.
