The 2023 Lexus LS500 carries the modern flagship-sedan mission in a way that blends Lexus luxury with a more athletic, technology-driven character than earlier large luxury cars. It is a full-size sedan where ride quality, quiet cruising, and confident high-speed road manners all depend heavily on getting the tire setup right. Tire fitment on the 2023 Lexus LS500 centers on radial sizes 245/50R19, 245/45R20, and, for the staggered F Sport rear position, 275/40R20. That creates meaningful choice in wheel diameter, staggered versus non-staggered fitment, and even sidewall presentation in some 20-inch options. The key is matching the exact sub-model and wheel setup before comparing brands, series, and appearance details.
Which Tire Size Is Right for The 2023 Lexus LS500
The 2023 Lexus LS500 uses three primary tire sizes, and the right one depends first on the exact wheel setup and sub-model. Base cars can use either 245/50R19 or 245/45R20, while the F Sport uses a staggered 20-inch arrangement with 245/45R20 in front and 275/40R20 in the rear. Before choosing a tire, confirm whether the car is on 19-inch or 20-inch wheels and whether it uses the F Sport front-and-rear combination.
245/45R20 is a modern metric radial size in which 245 identifies the section width in millimeters, 45 is the aspect ratio, R confirms radial construction, and 20 is the rim diameter in inches. On the 2023 Lexus LS500, this size is part of the 20-inch fitment and also serves as the front size on the F Sport setup. Available choices include BFGoodrich, Nitto, and Pro-Trac options, with blackwall, redline, and RWL sidewall treatments across several tire series. This size is the right place to focus if the car already wears 20-inch front wheels and the goal is to compare handling-oriented products or sidewall appearance.
245/50R19 is a modern metric radial size with a 245-millimeter section width, a 50-series profile, radial construction, and a 19-inch rim diameter. On the 2023 Lexus LS500, this size belongs to the 19-inch wheel fitment used on the Base model rather than the staggered F Sport arrangement. Product choices in this size center on BFGoodrich tire series with blackwall styling, giving the buyer a more focused selection within the correct fitment. This size matters most when the car retains its 19-inch wheels and the priority is staying with the proper rim diameter instead of moving into the 20-inch setup.
275/40R20 is a modern metric radial size where 275 is the nominal section width in millimeters, 40 is the aspect ratio, R indicates radial construction, and 20 is the rim diameter in inches. On the 2023 Lexus LS500, this is the rear tire size for the F Sport staggered configuration, so it should not be treated as a universal LS500 fitment. Available options include BFGoodrich, Nitto, M&H Racemaster, and Pro-Trac choices, mostly in blackwall form with additional redline and RWL selections. This size deserves careful attention any time the rear wheels, suspension, or overall staggered setup need to stay consistent with the car’s existing configuration.
Sub-model fitment matters on the 2023 Lexus LS500 because the Base and F Sport configurations do not use the same wheel-and-tire arrangement. Base fitment can be 19-inch or 20-inch, while the F Sport uses a staggered 20-inch setup that requires matching the correct front and rear sizes.

2023 Lexus LS500 Base
The 2023 Lexus LS500 Base uses either a 245/50R19 radial or a 245/45R20 radial, depending on the wheel package on the car. Tire selection starts with confirming rim diameter, then comparing available series, brand choices, and sidewall presentation within the correct size.
The 2023 Lexus LS500 F Sport Front uses 245/45R20 radial tires on a 20-inch wheel. That means front tire selection should stay focused on the correct 20-inch front size while keeping the staggered relationship with the wider rear tire in mind.
The 2023 Lexus LS500 F Sport Rear uses a wider 275/40R20 radial tire on a 20-inch wheel. Rear tire choice should account for the staggered setup, especially if the car has aftermarket wheels or any suspension changes that could affect rear clearance.
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 LS500?
The 2023 Lexus LS500 uses 245/50R19, 245/45R20, and 275/40R20 radial tire sizes. Base models can use either 245/50R19 or 245/45R20 depending on wheel package, while the F Sport uses a staggered setup with 245/45R20 in front and 275/40R20 in the rear.
The practical first step is confirming whether the car has 19-inch wheels or the 20-inch arrangement. On an F Sport, front and rear sizes are different, so replacing only one axle requires extra care to keep the intended staggered setup and wheel compatibility intact.
What size rim does a 2023 Lexus LS500 use?
The 2023 Lexus LS500 uses either 19-inch or 20-inch rims, depending on the configuration. The 245/50R19 size mounts on a 19-inch rim, while both 245/45R20 and 275/40R20 are built for 20-inch rims.
Wheel diameter should be verified before tire shopping, especially on cars that may have been changed from their original wheel package. A 20-inch tire cannot be used on a 19-inch wheel, and a staggered F Sport setup also requires confirming whether the front and rear wheel widths still match the intended tire sizes.
Why does the 2023 Lexus LS500 have more than one tire size?
The 2023 Lexus LS500 has more than one tire size because fitment changes with the wheel package and sub-model. Base cars may use either 245/50R19 or 245/45R20, while the F Sport adds a wider 275/40R20 rear tire as part of a staggered 20-inch setup.
That means tire selection is not just a matter of year and model name. The buyer should confirm the exact sub-model, then verify the actual wheel diameter on the car, and on F Sport cars, check both front and rear sizes separately before comparing tire series or sidewall style.
Choosing the Right Tire
What should I consider when choosing a 2023 Lexus LS500 tire?
Start with the correct size for the exact setup: 245/50R19 for a 19-inch Base fitment, 245/45R20 for a 20-inch front or Base fitment, and 275/40R20 for the F Sport rear. From there, compare radial construction details, brand availability, tire series, sidewall style, and any rim-width specifications that apply to the size being considered.
The best comparison is the one that matches how the car is actually used. A daily-driven LS500 may call for a different series than a car kept mainly for fair-weather use, and any wheel change, staggered setup, or appearance goal should be considered before settling on a final tire choice.
What sidewall styles are available for 2023 Lexus LS500 tires?
Sidewall choices for the 2023 Lexus LS500 include blackwall, redline, and RWL depending on tire size. The 245/45R20 and 275/40R20 sizes offer the widest appearance variety, while 245/50R19 choices shown here stay within blackwall options.
That makes sidewall treatment part of the decision, especially on 20-inch cars where appearance can change the car’s overall presentation. Redline and raised white letter options can create a more custom or performance-inspired look, while blackwall keeps the visual approach more restrained and contemporary.
What brands offer tires for the 2023 Lexus LS500?
Tires for the 2023 Lexus LS500 are available from BFGoodrich, Nitto, Pro-Trac, and M&H Racemaster, depending on size. BFGoodrich appears across all three fitment sizes here, while Nitto, Pro-Trac, and M&H Racemaster are concentrated in the 20-inch selections.
Brand choice should be weighed alongside the specific tire series, sidewall styling, and the exact front or rear fitment required. On a staggered F Sport, for example, the important question is not only which brand is available, but whether the chosen front and rear tires suit the car’s wheel setup and intended use.
Restoration & Appearance
How does tire construction affect the appearance of a restored 2023 Lexus LS500?
The 2023 Lexus LS500 uses radial tires, so construction choice is less about bias-ply versus radial appearance and more about the visual character of the specific tire. In this case, the biggest appearance differences come from sidewall treatments such as blackwall, redline, or RWL in the available 20-inch sizes.
For a restoration-minded or collector-kept LS500, the cleaner and more restrained look usually comes from matching the car’s wheel package and sidewall presentation to its existing style. If exact showroom-era appearance matters, compare the tire’s sidewall look to original vehicle photography, dealer materials, or marque-specific references before deciding.
Does correct tire fitment matter for a 2023 Lexus LS500 restoration?
Correct tire fitment matters because the 2023 Lexus LS500 was offered with more than one wheel-and-tire arrangement, and those setups change the car’s stance and overall presentation. A Base model on 19-inch 245/50R19 tires does not present the same way as a 20-inch car, and the F Sport adds a wider 275/40R20 rear tire.
Using the proper size for the actual sub-model and wheel package helps preserve the intended look while avoiding unnecessary fitment complications. Before selecting a tire for a restoration-oriented project, confirm the current wheels on the car and decide whether the goal is original-style presentation or a more customized appearance.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2023 Lexus LS500?
Yes, modifications can affect tire fitment on a 2023 Lexus LS500 even when the tire size itself is correct. Aftermarket wheels, wheel-width changes, altered offsets, lowered suspension, or body modifications can all change how 245/50R19, 245/45R20, or 275/40R20 tires sit within the wheelwell.
Clearance should be checked at full steering lock and through suspension movement, especially on the wider F Sport rear setup. Any LS500 that has been modified should also have its actual wheel diameter and width confirmed before tire replacement, since a stock size does not guarantee the same result on a changed chassis.
What should I inspect before driving a 2023 Lexus LS500 on new tires?
Before driving a 2023 Lexus LS500 on new tires, inspect the wheels for damage, confirm the tire sizes match the car’s actual setup, and make sure inflation pressures are set correctly. It is also wise to check for suspension wear, uneven old-tire wear patterns, and any signs that alignment issues may have been present before the new tires were installed.
A short initial road test can help reveal vibration, pull, rubbing, or other fitment concerns before longer driving. On an F Sport, verify that the front 245/45R20 and rear 275/40R20 positions have not been mixed, and on any LS500, recheck pressure and overall condition after the first miles.
How often should tires on a 2023 Lexus LS500 be inspected?
Tires on a 2023 Lexus LS500 should be inspected regularly, not just when tread looks low. A quick visual check every month and a closer inspection before longer trips helps catch cracking, punctures, bulges, uneven wear, and slow air loss before those issues become more serious.
Low-mileage luxury cars can still develop tire problems from age, storage, or infrequent use, so calendar time matters as much as mileage. During inspection, look at both sidewalls, confirm tread wear is even across the width, and pay special attention to rear tires on staggered F Sport cars because front-to-rear rotation is more limited.
