The 2025 Lexus LS500 carries the long-running LS tradition into a modern luxury sedan shaped as much by high-speed composure as by quiet road manners. Its tire fitment reflects that balance, with radial sizes that vary by wheel package and, in F Sport form, by front and rear position. The key sizes here are 245/50R19, 245/45R20, and the wider 275/40R20 rear fitment used on the F Sport setup. Available choices range from blackwall performance-oriented radials to redline and raised white letter options in select 20-inch sizes. The real task is confirming the exact wheel and sub-model configuration before choosing the tire style that best suits appearance, handling, and everyday use.
Which Tire Size Is Right for The 2025 Lexus LS500
The 2025 Lexus LS500 uses three primary tire sizes, and the right one depends on the exact sub-model and wheel setup. Two sizes fit 20-inch wheels, while one fits a 19-inch wheel, and the F Sport arrangement adds a staggered front-and-rear fitment. Before choosing a tire, identify whether the car is a Base model or an F Sport and confirm the wheel diameter already on the vehicle.
245/45R20 is a metric radial size in which 245 identifies the section width in millimeters, 45 is the aspect ratio, R denotes radial construction, and 20 is the rim diameter in inches. On the 2025 Lexus LS500, this size is part of the 20-inch fitment and also serves as the front tire size on the F Sport setup. Product choices include BFGoodrich, Nitto, and Pro-Trac offerings, with blackwall, redline, and raised white letter sidewall treatments available. It is the right size to evaluate when the car already wears 20-inch front wheels and the goal is balancing appearance with the character of the available radial series.
245/50R19 follows the same modern metric system, using a 245-millimeter section width, a 50-series profile, radial construction, and a 19-inch rim diameter. This size belongs to the 19-inch LS500 fitment and keeps the selection centered on blackwall radial tires rather than specialty sidewall treatments. BFGoodrich options in several g-Force series are available here, giving the buyer a choice among different radial product families within the same basic size. It is the size to focus on when the car remains on a 19-inch wheel package and the priority is staying with the correct wheel diameter and profile.
275/40R20 is a wider metric radial size, with 275 indicating section width in millimeters, 40 marking the aspect ratio, R for radial construction, and 20 for the wheel diameter. On the 2025 Lexus LS500, this is the rear tire size used with the F Sport staggered setup, so it should not be treated as a universal fitment for every LS500. Available choices include BFGoodrich, Nitto, M&H Racemaster, and Pro-Trac, with blackwall, redline, and raised white letter presentations depending on the tire series. It is the size to compare when the car uses the wider F Sport rear wheel and rear-position fitment needs to be preserved.
Sub-model fitment matters on the 2025 Lexus LS500 because tire sizing changes with wheel package and, on F Sport cars, by axle position. The first step is confirming whether the car is a Base model or an F Sport and then matching the tire to the wheel diameter and location on the vehicle.

2025 Lexus LS500 Base
The 2025 Lexus LS500 Base uses either a 245/50R19 or 245/45R20 radial, depending on the wheel package on the car. Tire selection starts with confirming whether the vehicle has 19-inch or 20-inch wheels, then comparing the available product families and sidewall treatments within that exact size.
The 2025 Lexus LS500 F Sport Front uses a 245/45R20 radial as part of a staggered fitment. That makes front-position confirmation important, especially when replacing tires in pairs or as a full set, since the front and rear sizes are not the same on this setup.
The 2025 Lexus LS500 F Sport Rear uses a wider 275/40R20 radial on the rear axle. Tire choice here should account for the rear wheel width and the staggered layout, particularly if the car has seen any wheel, suspension, or alignment changes since new.
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.
Best 2025 Lexus LS500 Tires for Sale
Available 2025 Lexus LS500 tire choices span BFGoodrich, Nitto, Pro-Trac, and M&H Racemaster depending on size. Buyers can compare blackwall performance radials across several series, while select 20-inch sizes also add redline and raised white letter options for a more distinctive appearance.
Common 2025 Lexus LS500 tire questions usually come down to identifying the correct size by sub-model and wheel package, then comparing radial choices by sidewall style, series, and intended use. The details below also cover staggered F Sport fitment, wheel compatibility, and road-use checks.
Tire Size & Fitment
What tire size fits a 2025 Lexus LS500?
The 2025 Lexus LS500 uses three primary tire sizes: 245/50R19, 245/45R20, and 275/40R20. Base models use either 245/50R19 or 245/45R20 depending on wheel package, while the F Sport setup uses 245/45R20 in front and 275/40R20 in the rear.
That means the correct answer depends on more than model name alone. Wheel diameter must be confirmed first, and on F Sport cars the front and rear positions must be checked separately before selecting tires, especially if the car has been fitted with aftermarket wheels or a different wheel package.
What size rim does a 2025 Lexus LS500 use?
The 2025 Lexus LS500 uses either a 19-inch or 20-inch rim, depending on configuration. The 245/50R19 size fits a 19-inch wheel, while both 245/45R20 and 275/40R20 fit 20-inch wheels, with the wider 275/40R20 used at the rear on the F Sport staggered setup.
Rim diameter is the first fitment detail to verify because a 19-inch tire cannot be mounted on a 20-inch wheel, and the reverse is equally true. After confirming diameter, check actual wheel width and front-versus-rear placement so the replacement tire matches the vehicle's present wheel arrangement.
Why does the 2025 Lexus LS500 have more than one tire size?
More than one tire size appears on the 2025 Lexus LS500 because the model can be equipped with different wheel packages, and the F Sport version uses a staggered setup. Base cars may use either 245/50R19 or 245/45R20, while F Sport cars pair 245/45R20 fronts with 275/40R20 rears.
This is not a case of interchangeable sizing across the whole model line. A buyer should confirm sub-model, wheel diameter, and whether the car uses the front or rear F Sport position before ordering replacements, since selecting by year, make, and model alone can miss an important fitment distinction.
Choosing the Right Tire
What should I consider when choosing a 2025 Lexus LS500 tire?
Start with the exact tire size already matched to the car's wheel package or axle position. A 2025 Lexus LS500 may use 245/50R19, 245/45R20, or 275/40R20, and all are radial tires, so the main selection factors become wheel compatibility, tire series, sidewall style, and intended road use.
Once size is settled, compare the product details that actually affect the outcome. On this model that can include brand, blackwall versus redline or raised white letter appearance in select 20-inch sizes, and wheel-width suitability where stated, especially on the wider 275/40R20 rear fitment.
What sidewall styles are available for 2025 Lexus LS500 tires?
Sidewall style depends on size. Blackwall tires are available across all three LS500 sizes here, while the 20-inch sizes 245/45R20 and 275/40R20 also offer redline and RWL, or raised white letter, sidewall treatments through select Pro-Trac Street Pro III applications.
That gives the 20-inch fitments a broader appearance range than the 19-inch fitment. Buyers who want a more understated late-model luxury presentation may stay with blackwalls, while those looking for a stronger visual accent should first confirm that the car uses one of the supported 20-inch sizes.
What brands offer tires for the 2025 Lexus LS500?
Tire choices for the 2025 Lexus LS500 include BFGoodrich, Nitto, Pro-Trac, and M&H Racemaster, depending on size. BFGoodrich appears across all three fitments, Nitto is available in both 20-inch sizes, Pro-Trac adds redline and raised white letter options in select 20-inch applications, and M&H Racemaster appears in 275/40R20.
Brand choice should follow the fitment rather than lead it. Once the correct size and wheel setup are confirmed, compare each brand's available series, sidewall treatment, and wheel-width specification so the tire matches both the vehicle's configuration and the owner's intended use.
Restoration & Appearance
Which tire should I choose for a period-style 2025 Lexus LS500?
A period-style approach on a 2025 Lexus LS500 usually begins with preserving the correct modern radial size for the car's wheel package. From there, blackwall choices keep the presentation closest to a contemporary luxury-sedan look, while select 20-inch sizes add redline and raised white letter options for a more customized appearance.
Because this is a current-era luxury model, appearance choice is less about vintage restoration practice and more about keeping the look consistent with the car's trim and wheel setup. The safest path is to confirm the exact size first, then choose the sidewall treatment that best suits the vehicle's overall style.
How does tire construction affect the appearance of a restored 2025 Lexus LS500?
On the 2025 Lexus LS500, the primary fitments are all radial, so construction choice does not create a bias-ply-versus-radial appearance decision. Visual character instead comes more from sidewall treatment, with blackwall available broadly and redline or raised white letter available in certain 20-inch sizes.
For an owner focused on presentation, keeping the correct size and wheel relationship matters more than chasing a different construction type. A tire that matches the proper diameter and profile will usually preserve the intended stance better than a visually interesting option chosen without checking the actual wheel setup.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2025 Lexus LS500?
Yes, modifications can affect tire fitment on a 2025 Lexus LS500 even when the tire size itself is correct. Aftermarket wheels, different wheel widths, altered offsets, suspension changes, or lowering can all change how a 245/50R19, 245/45R20, or 275/40R20 tire sits within the fender and steering range.
That matters most on the F Sport staggered setup, where front and rear sizes already differ. Any modified LS500 should be checked for wheel clearance, steering sweep, and rear suspension space before replacement tires are chosen, rather than assuming the original size alone settles the fitment question.
What should I inspect before driving a 2025 Lexus LS500 on new tires?
Before road use, inspect tire pressure, wheel fastener torque, visible seating on the rim, and the directional or positional placement if the car uses a staggered setup. A 2025 Lexus LS500 with F Sport fitment should be checked carefully to make sure the 245/45R20 front and 275/40R20 rear tires are not reversed.
A quick follow-up inspection after the first miles is also worthwhile. Look for any sign of rubbing, uneven stance, vibration, or air loss, and confirm that the tire clears suspension and body components through normal steering and ride movement, particularly if the car does not remain on stock wheels.
How often should tires on a 2025 Lexus LS500 be inspected?
Tires on a 2025 Lexus LS500 should be inspected regularly, not just when tread appears worn. Check them for pressure loss, cuts, bulges, irregular wear, and sidewall damage, and pay extra attention if the car sees long highway trips, curb contact, or long periods of sitting between drives.
Routine inspections matter because this model can use different wheel packages and, in F Sport form, different front and rear sizes. Keeping an eye on wear patterns can also reveal alignment or suspension issues early, which is especially helpful when a wide 275/40R20 rear tire is part of the setup.
