The 2023 Lexus LC500 blends grand-touring luxury with dramatic coupe styling, making tire choice more than a basic replacement decision. Its low, wide stance and performance-focused setup put extra importance on keeping the correct front and rear sizing relationship intact. This LC500 uses staggered radial fitments, with 20-inch and 21-inch wheel-and-tire combinations depending on the setup on the car. That means the real choice is not just size, but also whether the car is on 20s or 21s and which brand, series, and sidewall presentation best matches the way it is driven. Before selecting tires, confirm wheel diameter front and rear and check whether the car remains on its original wheel setup.
Which Tire Size Is Right for The 2023 Lexus LC500
The 2023 Lexus LC500 uses four primary tire sizes across a staggered front-and-rear setup, and the first step is confirming whether the car is equipped with 20-inch or 21-inch wheels. Front and rear sizes differ, so the correct choice depends on both wheel diameter and axle position before comparing brands, sidewall styles, or tire series.
245/45R20 is a metric radial size, with 245 millimeters of nominal section width, a 45-series profile, radial construction, and a 20-inch rim diameter. On the 2023 Lexus LC500, it is the front tire size for the 20-inch staggered combination and is also the size with the broadest visible product variety here. Available choices include BFGoodrich, Nitto, and Pro-Trac options, along with Blackwall, Redline, and RWL sidewall treatments across several tire series. This is the size to evaluate when the car is on 20-inch front wheels and the goal is to compare appearance as well as basic fitment.
275/35R21 is a metric radial size where 275 is the nominal section width in millimeters, 35 is the aspect ratio, R denotes radial construction, and 21 indicates rim diameter in inches. On the LC500, this size belongs to the rear of the 21-inch staggered arrangement and should be kept paired with the correct 21-inch front size. Its shorter profile and wider section reflect the car's rear performance fitment rather than a universal all-position tire choice. Confirming rear wheel diameter and making sure the car has not been converted to a 20-inch package are the key checks before pursuing this size.
275/40R20 is a metric radial size with a 275-millimeter nominal section width, 40-series profile, radial construction, and 20-inch rim diameter. It serves the rear position on the 20-inch LC500 setup and should be matched with the correct 20-inch front size to preserve the staggered relationship. Product choices in this size include BFGoodrich, Nitto, Pro-Trac, and M&H Racemaster, with Blackwall, Redline, and RWL presentations represented across different series. This is the rear size to compare when the car is running 20-inch wheels and the owner wants to balance fitment, appearance, and intended use.
Sub-model fitment on the 2023 Lexus LC500 is straightforward in layout but still requires attention because the car uses different sizes at the front and rear. Checking axle position and wheel diameter matters first, since the front fitments and rear fitments are not interchangeable.

2023 Lexus LC500 Base Front
The 2023 Lexus LC500 Base Front uses radial front tire sizing in either a 20-inch or 21-inch configuration, depending on the wheel package on the car. That makes front-wheel diameter the key confirmation before comparing available brands, tire series, or sidewall treatments.
The 2023 Lexus LC500 Base Rear uses a wider radial rear tire, again split between 20-inch and 21-inch wheel setups. Tire selection at the rear should focus on matching the existing wheel diameter and maintaining the proper staggered relationship with the front tires.
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.

These FAQs focus on the staggered tire setup used on the 2023 Lexus LC500, including front-versus-rear sizing, 20-inch versus 21-inch wheel fitment, available product choices, and the checks that matter before road use.
Tire Size & Fitment
What tire size fits a 2023 Lexus LC500?
The 2023 Lexus LC500 uses a staggered radial setup with four primary sizes across two wheel diameters. Front sizes are 245/45R20 or 245/40R21, while rear sizes are 275/40R20 or 275/35R21.
The correct choice depends on whether the car has 20-inch or 21-inch wheels and whether the tire is for the front or rear axle. Front and rear sizes are not the same, so the most important first step is verifying the wheel diameter on the car and keeping the front-to-rear pairing consistent.
What size rim does a 2023 Lexus LC500 use?
The 2023 Lexus LC500 uses either 20-inch or 21-inch rims, depending on the wheel-and-tire package on the car. The 20-inch setup uses 245/45R20 in front and 275/40R20 in the rear, while the 21-inch setup uses 245/40R21 in front and 275/35R21 in the rear.
Wheel diameter should be confirmed before looking at any tire options, because the LC500 does not use one universal rim size across all configurations. It is also worth checking whether the car still has its original wheel setup, since aftermarket wheels can change both rim width and the tire size that will work safely.
Why does the 2023 Lexus LC500 have more than one tire size?
The 2023 Lexus LC500 has more than one tire size because it uses a staggered arrangement with different sizes at the front and rear, and it appears with either a 20-inch or 21-inch wheel package. That creates two front sizes and two rear sizes rather than a single all-around fitment.
For tire selection, that means the job starts with identifying both axle position and wheel diameter. A front tire should not be chosen from the rear sizes, and a 20-inch fitment should not be mixed with a 21-inch one unless the full wheel-and-tire setup has been intentionally changed and properly checked.
Choosing the Right Tire
What should I consider when choosing a 245/45R20 tire for a 2023 Lexus LC500?
A 245/45R20 tire for a 2023 Lexus LC500 should first match the car's 20-inch front-wheel setup. After confirming the size, compare radial tire series, rim-width compatibility, sidewall style, and any load information that may matter for the way the car is used.
This size includes choices from BFGoodrich, Nitto, and Pro-Trac, so the decision may come down to whether the goal is a straightforward Blackwall look or a more distinctive Redline or RWL presentation. Keeping the tire matched to the front axle position and compatible with the actual wheel width is more important than choosing by brand name alone.
What sidewall styles are available for 2023 Lexus LC500 tires?
Available 20-inch LC500 tire options include Blackwall, Redline, and RWL sidewall styles. Blackwall appears across several BFGoodrich, Nitto, and M&H Racemaster products, while Redline and RWL appear in Pro-Trac Street Pro III options for both 245/45R20 and 275/40R20 sizes.
Sidewall style mostly affects the visual character of the car, so it becomes an appearance choice once the correct size and wheel diameter are established. Redline or raised white letter styling can give the LC500 a more custom presentation, while Blackwall keeps the look cleaner and closer to a modern performance-tire appearance.
What brands offer tires for the 2023 Lexus LC500?
The available 20-inch tire choices for the 2023 Lexus LC500 include BFGoodrich, Nitto, Pro-Trac, and M&H Racemaster. These brands appear across front and rear 20-inch sizes, with multiple tire series represented in Blackwall, Redline, and RWL form.
Brand selection should still come after confirming the exact size needed for the front or rear axle. It also helps to compare the series within a brand, since the LC500's tire choices vary not just by brand name but by intended use, sidewall treatment, and wheel-width compatibility for the specific size being considered.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2023 Lexus LC500?
Yes, modifications can affect tire fitment on a 2023 Lexus LC500. Changes such as aftermarket wheels, altered wheel widths, suspension lowering, or body modifications can change the space available for the factory-style staggered tire sizes and can also alter which rim-width ranges are appropriate.
Any LC500 that has been changed from its original wheel package should be checked carefully before replacement tires are selected. Wheel diameter, wheel width, front and rear clearance, and steering travel all matter, especially because this car already uses different tire sizes at each axle and may not tolerate casual substitutions.
What should I inspect before driving a 2023 Lexus LC500 on new tires?
Before driving a 2023 Lexus LC500 on new tires, inspect that the correct front and rear sizes were installed, confirm inflation pressure, and make sure each tire is seated properly on the wheel. It is also smart to look for any immediate rubbing, uneven spacing, or clearance issues at full steering lock.
A short, careful road test can help confirm that the car tracks properly and that there is no contact under turning or compression. On a staggered setup like the LC500's, it is especially important to make sure the front tires and rear tires were not mixed by size and that wheel hardware and valve stems are in good condition.
What should I check before a longer drive in a 2023 Lexus LC500?
Before a longer drive in a 2023 Lexus LC500, check tire pressure, tread condition, sidewall condition, and any signs of punctures, cuts, bulges, or irregular wear. It is also worth confirming that all four tires match the correct front-and-rear size arrangement for the wheel package on the car.
Longer trips put more emphasis on condition than simple storage use, so recheck the tires after the first few miles if they were recently installed. A vehicle that sits for extended periods also deserves extra attention to aging, flat spotting, and slow air loss before heading out for sustained highway driving.
