The 2023 Lexus LC500h blends grand touring luxury with a low, sculpted coupe profile and a hybrid powertrain, so tire fitment is part of both its appearance and its road manners. On this model, the key fitment question is confirming whether the car is on the 20-inch or 21-inch staggered wheel setup, because the front and rear sizes differ. Primary sizes include 245/45R20 and 275/40R20 on 20-inch rims, or 245/40R21 and 275/35R21 on 21-inch rims, all in radial construction. Available choices also vary by brand, tire series, and sidewall treatment. That makes wheel confirmation the first step before comparing style, use, and overall presentation.
Which Tire Size Is Right for The 2023 Lexus LC500h
The 2023 Lexus LC500h uses four primary tire sizes across a staggered front-and-rear setup, with fitment split between 20-inch and 21-inch wheel packages. The first step is confirming wheel diameter and whether you are selecting a front or rear tire, since the front sizes are 245-section tires and the rear sizes are 275-section tires, all in radial construction.
245/40R21 is a metric radial size in which 245 is the section width in millimeters, 40 is the aspect ratio, R identifies radial construction, and 21 is the wheel diameter in inches. On the 2023 Lexus LC500h, this size serves as a front fitment on the 21-inch staggered setup, pairing with a wider 21-inch rear tire. Its role is not interchangeable with the rear size, so position on the car matters as much as the size itself. Choose this size only after confirming the car is equipped with the 21-inch front wheel package.
245/45R20 is a metric radial size that denotes a 245-millimeter nominal section width, a 45-series profile, radial construction, and a 20-inch rim diameter. On the 2023 Lexus LC500h, this is the front tire size for the 20-inch staggered arrangement, matched with a wider 275/40R20 rear. Available options in this size include BFGoodrich, Nitto, and Pro-Trac products, with blackwall, redline, and raised white letter sidewall treatments depending on the tire series. It is the right size to evaluate when the car has 20-inch front wheels and you want to compare appearance-oriented and performance-oriented choices.
275/35R21 is a metric radial size in which 275 indicates nominal section width in millimeters, 35 is the aspect ratio, R marks radial construction, and 21 indicates a 21-inch wheel. On the 2023 Lexus LC500h, this size is used at the rear on the 21-inch staggered setup, where it complements the narrower 245/40R21 front tire. Because it is a rear-specific fitment, it should be chosen with the car's wheel package and tire position in mind rather than treated as a universal 21-inch option. Confirming rear wheel diameter is essential before moving into product selection.
275/40R20 is a metric radial size that combines a 275-millimeter nominal section width with a 40-series profile on a 20-inch rim. For the 2023 Lexus LC500h, it serves as the rear fitment on the 20-inch staggered wheel setup and works alongside a 245/45R20 front tire. Product choices in this size include BFGoodrich, Nitto, Pro-Trac, and M&H Racemaster, with blackwall, redline, and raised white letter options plus several distinct tire series. This is the size to review when the car has 20-inch rear wheels and you want to compare street-focused and specialty radial choices.
Fitment on the 2023 Lexus LC500h is straightforward in one sense and specific in another: the covered sub-model positions separate front and rear tire sizes. Checking whether you are replacing a front or rear tire, and whether the car has 20-inch or 21-inch wheels, matters before selecting any product.

2023 Lexus LC500h Base Front
The 2023 Lexus LC500h Base Front uses the narrower front tire sizes in the staggered setup, with one size tied to the 20-inch wheel package and the other tied to the 21-inch package. Tire selection here starts with wheel diameter confirmation, then moves into brand, series, and sidewall preferences within the correct front size.
The 2023 Lexus LC500h Base Rear uses the wider rear tire sizes that complete the staggered fitment, again split between 20-inch and 21-inch wheel packages. Choosing the right rear tire means matching the wheel diameter first, then comparing the available radial products and sidewall styles in the proper rear size.
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 LC500h?
The 2023 Lexus LC500h uses a staggered radial tire setup with four primary sizes across two wheel diameters. Front fitment is 245/45R20 or 245/40R21, while rear fitment is 275/40R20 or 275/35R21. The 20-inch and 21-inch packages are separate, so the correct size depends on both wheel diameter and whether the tire is for the front or rear axle.
That means the first check is not just the year and model, but the actual wheel package on the car. Looking at the sidewall of the existing tires and confirming front-versus-rear position will prevent mixing sizes that belong to different staggered setups. Any car with replacement wheels should also have wheel diameter and width verified before selecting tires.
What size rim does a 2023 Lexus LC500h use?
The 2023 Lexus LC500h uses either 20-inch or 21-inch rims, depending on the wheel package. The 20-inch setup pairs 245/45R20 in front with 275/40R20 in the rear, while the 21-inch setup uses 245/40R21 in front and 275/35R21 in the rear. All of these are radial tire sizes built around those respective rim diameters.
Rim diameter should be confirmed before anything else because a 20-inch tire and a 21-inch tire are not interchangeable. It also helps to verify whether the car still has its original wheel package or an aftermarket setup. On a staggered coupe like the LC500h, front and rear rim width can matter just as much as diameter when comparing tire options.
Why does the 2023 Lexus LC500h have more than one tire size?
The 2023 Lexus LC500h has more than one tire size because it uses a staggered arrangement and is associated with two different wheel diameters. The front tires are narrower than the rear tires, and each wheel package has its own matched front-and-rear sizes. That creates four primary sizes overall rather than one universal fitment for the entire car.
For a buyer, that means tire selection starts by identifying both the wheel diameter and the axle position. A front 245-section tire should not be substituted for the rear, and a 20-inch setup should not be mixed with 21-inch sizing. Checking the existing sidewalls, wheel markings, and any prior wheel changes is the safest way to narrow the right fitment.
Choosing the Right Tire
What should I consider when choosing a 245/45R20 tire for a 2023 Lexus LC500h?
A 245/45R20 tire for the 2023 Lexus LC500h should be chosen by confirming that the car uses the 20-inch front fitment first, then comparing construction details and product character within that size. Available options include BFGoodrich, Nitto, and Pro-Trac radials, with several series names and different sidewall treatments depending on the look and purpose you want.
Selection becomes more useful when narrowed by how the car is driven and how you want it to present visually. Some products publish rim-width ranges and load figures, which are worth comparing against the actual wheel on the car. Matching the front tire correctly also helps preserve the intended relationship with the wider 275/40R20 rear tire.
What sidewall styles are available for 2023 Lexus LC500h tires?
For the 2023 Lexus LC500h's available 20-inch tire options, sidewall styles include blackwall, redline, and RWL, which is raised white letter. Those choices appear within the 245/45R20 and 275/40R20 fitments, giving buyers a way to change the visual presentation without stepping outside the correct primary size for the wheel package and axle position.
Sidewall style is mainly an appearance decision, but it still needs to be made within the correct front or rear size. A blackwall keeps the presentation subtle, while redline or raised white letter options add a more expressive look. The best comparison is between tires that share the proper size and wheel compatibility rather than between sidewall styles alone.
What brands offer tires for the 2023 Lexus LC500h?
Available 20-inch tire options for the 2023 Lexus LC500h come from BFGoodrich, Nitto, Pro-Trac, and M&H Racemaster. Those brands cover several tire series in the applicable front and rear sizes, including blackwall performance-oriented choices as well as redline and raised white letter alternatives for a more distinctive look.
Brand should be considered alongside the exact size, tire position, sidewall treatment, and any published wheel-width or load information. Rather than choosing by name alone, compare which brand offers the series and appearance that suits the car's setup. The right match starts with the correct front or rear LC500h size and the correct 20-inch wheel package.
Restoration & Appearance
Which sidewall style suits a period-style 2023 Lexus LC500h?
A period-style look for a 2023 Lexus LC500h can take more than one direction, so the right sidewall depends on the presentation you want. Blackwall options keep the car closest to a modern grand touring appearance, while redline and raised white letter choices add a stronger custom or enthusiast visual statement within the correct 20-inch sizes.
Appearance should still be built around the proper front and rear fitment rather than chosen as a stand-alone styling detail. On a contemporary coupe like the LC500h, sidewall treatment changes the character of the car quickly, especially with staggered wheels. Comparing the sidewall options within the correct size is the cleanest way to refine the overall look.
Does correct tire fitment matter for a 2023 Lexus LC500h restoration or appearance build?
Correct tire fitment matters because the 2023 Lexus LC500h relies on a staggered setup that affects both stance and overall presentation. Using the proper front and rear sizes for the actual 20-inch or 21-inch wheel package keeps the proportions balanced. That is especially important on a low, sculpted coupe where tire shape and sidewall profile are visually prominent.
An appearance-focused build can still leave room for personal choices in brand, series, and sidewall style, but those decisions work best after the fitment is nailed down. Any car with aftermarket wheels, altered ride height, or cosmetic modifications should have wheel dimensions and clearances checked carefully. Good visual results start with the right size in the right position.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2023 Lexus LC500h?
Yes, modifications can affect tire fitment on a 2023 Lexus LC500h, especially because the car uses staggered front-and-rear sizes and two possible wheel diameters. Aftermarket wheels, suspension changes, or altered ride height can change the relationship between the tire, fender, and steering components. Even when the sidewall size matches, the wheel itself may not duplicate the original setup.
Any modified LC500h should have wheel diameter, wheel width, and tire position checked before replacement. Clearance during turning and suspension movement matters just as much as the printed size. A car with non-original wheels may also need closer comparison of published rim-width specifications on available tires, particularly in the wider 275 rear fitments.
What should I inspect before driving a 2023 Lexus LC500h on new tires?
Before driving a 2023 Lexus LC500h on new tires, inspect that the correct front and rear sizes were installed for the car's actual 20-inch or 21-inch wheel package. Tire pressure, wheel fastener torque, sidewall condition, and visible clearance around suspension and fender areas are all worth checking. A staggered setup deserves extra attention so front and rear positions are not mixed.
A short initial drive should be followed by another visual check for rubbing, unusual wear, or air loss. It is also smart to confirm that the tire's sidewall markings match the intended axle position before putting more miles on the car. Any vibration, pull, or contact under steering load should be addressed before longer road use.
How often should tires on a 2023 Lexus LC500h be inspected?
Tires on a 2023 Lexus LC500h should be inspected regularly, not just when tread looks worn. A quick visual check before routine driving can catch pressure loss, cuts, bulges, or irregular wear, and a more thorough inspection at regular service intervals helps confirm that the staggered front and rear tires are wearing evenly for their position on the car.
Cars that are driven less often still benefit from frequent inspection because low annual mileage can hide aging or slow air loss. Pay close attention to sidewall condition, tread depth across the full width, and any signs of contact if the car has aftermarket wheels or suspension changes. Consistent checks help preserve both appearance and road manners.
