The 2024 Lexus LS500h carries the long-running LS tradition into the modern hybrid luxury-sedan era, blending quiet highway composure with contemporary wheel-and-tire fitments that are far removed from vintage numeric sizing. For this exact model, the key tire decision starts with two radial sizes, 245/45R20 and 245/50R19, tied to different wheel diameters. That makes wheel confirmation just as important as size selection. Available choices also vary by brand, series, and sidewall treatment, including blackwall, redline, and raised white letter options in the 20-inch size. Whether the goal is refined road use or a more distinctive appearance, the right match begins with the actual wheel setup on the car.
Which Tire Size Is Right for The 2024 Lexus LS500h
The 2024 Lexus LS500h uses two primary tire sizes, and both are radial fitments with different rim diameters. The Base model can use either 245/45R20 or 245/50R19, so the first step is confirming whether the car has 19-inch or 20-inch wheels before comparing product options. Once that is settled, the decision shifts to tire series, sidewall style, and the overall character you want from the replacement tire.
A 245/45R20 size uses a 245-millimeter nominal section width, a 45-series aspect ratio, radial construction, and a 20-inch rim. On the 2024 Lexus LS500h, this is the lower-profile of the two primary fitments and it belongs only on cars equipped with 20-inch wheels. Product choices in this size include BFGoodrich, Nitto, and Pro-Trac options, with blackwall, redline, and RWL sidewall treatments represented across several tire series. This size is the right place to focus if the car already wears 20-inch wheels and you want to compare both performance-oriented and appearance-driven options.
A 245/50R19 tire keeps the same 245-millimeter nominal width but uses a 50-series aspect ratio and mounts on a 19-inch rim. For the 2024 Lexus LS500h, this radial size applies to cars equipped with 19-inch wheels rather than the 20-inch setup. Available choices in this size center on BFGoodrich g-Force series products, all in blackwall form, with differences in series, rim-width specification, and other product details. This size deserves attention when maintaining the existing 19-inch wheel package and keeping the fitment aligned with that wheel diameter.
Sub-model fitment is straightforward here because the 2024 Lexus LS500h Base is the covered configuration, but tire choice still depends on wheel diameter. Since this sub-model uses both 245/45R20 and 245/50R19, confirming the actual wheel setup on the car matters before selecting a tire.

2024 Lexus LS500h Base
The 2024 Lexus LS500h Base can use either of the two primary radial sizes, depending on whether it has 19-inch or 20-inch wheels. That means tire selection begins with wheel confirmation, then moves to comparing available series, sidewall presentation, and other product differences within the correct 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.

Available 2024 Lexus LS500h tire options vary by wheel size, brand, tire series, and sidewall style. The 20-inch fitment brings BFGoodrich, Nitto, and Pro-Trac choices with blackwall, redline, and RWL treatments, while the 19-inch fitment centers on blackwall BFGoodrich g-Force series tires.
Common 2024 Lexus LS500h tire questions usually come down to choosing between the two correct sizes, confirming 19-inch versus 20-inch wheels, and comparing available radial tire styles, brands, and fitment details before road use.
Tire Size & Fitment
What tire size fits a 2024 Lexus LS500h?
The 2024 Lexus LS500h uses two primary tire sizes: 245/45R20 and 245/50R19. Both are radial fitments, and the difference between them is tied mainly to wheel diameter, with one size for 20-inch wheels and the other for 19-inch wheels.
The practical step is to confirm the wheels actually installed on the car before selecting a tire. Since the Base model can use either size, choosing by year and model alone is not enough; the wheel package on the vehicle determines which of the two radial sizes belongs there.
What size rim does a 2024 Lexus LS500h use?
A 2024 Lexus LS500h uses either a 20-inch or 19-inch rim, depending on which of the two primary tire sizes is on the car. The 245/45R20 size mounts on a 20-inch rim, while the 245/50R19 size mounts on a 19-inch rim.
That makes rim diameter the first fitment checkpoint before comparing tires. A 20-inch tire cannot be used on a 19-inch wheel, and a 19-inch tire cannot be used on a 20-inch wheel, so checking the sidewall marking on the current tire or measuring the wheel is the safest place to start.
Why does the 2024 Lexus LS500h have more than one tire size?
The 2024 Lexus LS500h has more than one tire size because it can be equipped with different wheel diameters. Both fitments use the same 245-millimeter nominal width, but one is a 245/45R20 for 20-inch wheels and the other is a 245/50R19 for 19-inch wheels.
That means the correct tire is determined by the actual wheel package on the car rather than by the model name alone. Once the wheel diameter is confirmed, the next step is comparing the available products in that exact size for sidewall style, tire series, and other specifications that matter to your driving goals.
Choosing the Right Tire
What should I consider when choosing a 245/45R20 or 245/50R19 tire for a 2024 Lexus LS500h?
Start with the correct primary size for the wheel diameter on the car: 245/45R20 for a 20-inch wheel or 245/50R19 for a 19-inch wheel. From there, compare radial tire series, sidewall style, rim-width specifications, weight, and any stated load details that are relevant to the way the car is used.
The choice is less about finding an alternate size and more about choosing the right tire within the correct size. Owners focused on a cleaner modern look may stay with blackwall options, while those wanting a more distinctive presentation may be drawn to the redline or RWL choices offered in the 20-inch fitment.
What sidewall styles are available for 2024 Lexus LS500h tires?
Sidewall style depends on the tire size. In 245/45R20, available sidewall treatments include blackwall, redline, and RWL, while the 245/50R19 fitment is represented by blackwall options.
That gives the 20-inch setup more visual variety if appearance matters along with fitment. The key is to choose the sidewall treatment only after confirming the wheel diameter, since selecting a style in the wrong size does not solve the primary fitment requirement for the car.
What brands offer tires for the 2024 Lexus LS500h?
Available brands for the 2024 Lexus LS500h include BFGoodrich, Nitto, and Pro-Trac, although availability varies by size. The 245/45R20 fitment includes all three brands, while the 245/50R19 fitment centers on BFGoodrich choices.
Brand comparison only becomes meaningful after the correct wheel diameter and tire size are confirmed. Once that is done, the buyer can compare tire series, sidewall treatment, rim-width specifications, and other details within the applicable size instead of assuming every brand offers the same fitment across both wheel packages.
Restoration & Appearance
Which tire should I choose for a period-style 2024 Lexus LS500h?
A period-style approach on a 2024 Lexus LS500h is more about visual preference than restoration in the vintage sense, since both primary fitments are modern radial sizes. The 245/45R20 size offers the most appearance variety, including blackwall, redline, and RWL options, while the 245/50R19 choices are blackwall-focused.
Choosing for appearance still starts with the actual wheel diameter on the car. Once the correct size is confirmed, sidewall treatment and tire series become the main tools for shaping the look, whether the goal is a subtle factory-inspired presentation or something with more visual contrast.
How does tire construction affect the appearance of a restored or carefully kept 2024 Lexus LS500h?
On a 2024 Lexus LS500h, tire construction is straightforward because the primary fitments are radial. That means appearance differences come less from bias-ply-versus-radial decisions and more from profile, wheel diameter, and sidewall treatment within the correct radial size.
For a carefully kept example, the visible effect usually comes from whether the car wears the 19-inch or 20-inch wheel package and whether the tire is blackwall, redline, or RWL. Keeping the correct size for the installed wheels matters more than chasing a visual theme that ignores the car’s actual fitment.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2024 Lexus LS500h?
Yes, modifications can affect tire fitment on a 2024 Lexus LS500h even when the tire size itself is correct. Aftermarket wheels, changes in wheel width, offset differences, suspension alterations, or body modifications can all change how a 245/45R20 or 245/50R19 tire sits in the wheel opening.
That is why the installed wheel setup matters just as much as the nominal tire size. Any LS500h with non-original wheels or suspension changes should be checked for steering clearance, fender clearance, and proper wheel-to-tire compatibility before a new set is chosen for regular road use.
What should I inspect before driving a 2024 Lexus LS500h on new tires?
Before driving a 2024 Lexus LS500h on new tires, confirm that the tire size matches the wheel diameter, check inflation pressure, and inspect the wheels for damage or irregular wear. It also helps to look at valve stems, verify proper mounting direction if applicable, and make sure the tires seat correctly on the rims.
A short initial road test should be followed by another visual inspection. Any vibration, rubbing, unusual noise, or air loss deserves immediate attention, especially on a car that may have aftermarket wheels or a prior alignment issue that could affect how the new tires behave on the road.
What should I check before a longer drive in a 2024 Lexus LS500h?
Before a longer drive, check tire pressure, tread condition, visible cuts, punctures, bulges, and any signs of sidewall damage on the 2024 Lexus LS500h. It is also wise to confirm that all four tires are the correct size for the installed wheels and that there is no uneven wear pattern developing.
Longer trips put more emphasis on condition and consistency than a short local drive. A quick review of wheel hardware, alignment behavior, and any past air-loss issue can prevent trouble later, and any car that has sat for extended periods deserves an extra look for age-related cracking before heading out.
