The 2020 Lexus LS500h sits at the modern end of the flagship luxury-sedan tradition, blending full-size comfort with the more technical character expected from a contemporary hybrid Lexus. Tire selection on this car is more configuration-sensitive than it first appears, because the LS500h uses 245/50R19, 245/45R20, and 275/40R20 radial sizes depending on wheel setup and axle position. That makes the first decision a fitment one, especially on 20-inch applications that use a narrower front and wider rear arrangement. From there, the choice shifts to sidewall style, tire series, and whether the goal is understated road use or a more distinctive visual presentation.
Which Tire Size Is Right for The 2020 Lexus LS500h
The 2020 Lexus LS500h uses three primary tire sizes, and the correct choice depends on the exact wheel package and, in some cases, whether the tire is for the front or rear axle. Both 19-inch and 20-inch rim diameters appear here, so confirming the wheel diameter and the specific vehicle setup is the first step before comparing brands, sidewall treatments, or tire series.
245/45R20 is a modern metric radial size in which 245 refers to section width in millimeters, 45 is the aspect ratio, R identifies radial construction, and 20 is the rim diameter in inches. On the 2020 Lexus LS500h, this size is part of the 20-inch fitment and also serves as the front size on the staggered Base Front and Base Rear setup. Available choices include blackwall performance-oriented lines from BFGoodrich and Nitto, along with Pro-Trac Street Pro III options in redline and raised white letter form. This size is the one to evaluate when the car wears 20-inch front wheels and appearance matters alongside road manners.
245/50R19 is a modern metric radial size with a 245-millimeter nominal section width, a 50-series aspect ratio, radial construction, and a 19-inch rim diameter. For the 2020 Lexus LS500h, this is the 19-inch fitment used on the Base configuration rather than the staggered 20-inch arrangement. Product choices center on BFGoodrich g-Force series options, including Comp 2 AS, Sport Comp 2, and Phenom T/A, all presented in blackwall form. This size is the right place to focus when the priority is keeping the LS500h on its 19-inch wheel setup instead of moving into the wider 20-inch fitment family.
275/40R20 is a modern metric radial size in which the 275-millimeter width is broader than the front 245 size, the 40 denotes the aspect ratio, and the tire fits a 20-inch rim. On the 2020 Lexus LS500h, this size is used at the rear in the staggered 20-inch Base Front and Base Rear setup. The selection includes blackwall offerings from BFGoodrich, Nitto, and M&H Racemaster, plus Pro-Trac Street Pro III choices in redline and raised white letter form. This is the size to confirm carefully when the car has a wider rear-wheel arrangement and rear-axle fitment is being replaced.
Sub-model fitment on the 2020 Lexus LS500h is not completely uniform, because some versions use a single 19-inch setup while others use a 20-inch front and rear combination. Checking the exact sub-model matters before choosing a tire, especially when front and rear sizes differ.

2020 Lexus LS500h Base
The 2020 Lexus LS500h Base can appear with either the 245/50R19 radial size or the 245/45R20 radial size, depending on the wheel package on the car. Tire selection starts with confirming whether the vehicle is on 19-inch or 20-inch wheels before comparing tire series or sidewall presentation.
The 2020 Lexus LS500h Base Front uses the 245/45R20 radial size as the front fitment in the staggered 20-inch arrangement. That means the front tires should be chosen with the matching 20-inch front setup in mind rather than assuming the same size is used at all four corners.
The 2020 Lexus LS500h Base Rear uses the wider 275/40R20 radial size at the back of the staggered 20-inch setup. Rear tire selection should account for that wider fitment and should be matched carefully against the front size already on the vehicle.
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.

Common 2020 Lexus LS500h tire questions usually come down to identifying the correct size by wheel package and axle position, then comparing radial choices by brand, sidewall style, and intended use. The details below focus on fitment, selection, and practical road-use checks.
Tire Size & Fitment
What tire size fits a 2020 Lexus LS500h?
The 2020 Lexus LS500h uses three primary tire sizes: 245/50R19, 245/45R20, and 275/40R20. The exact size depends on the wheel setup and sub-model configuration, with 245/45R20 used on 20-inch front fitments and 275/40R20 used on 20-inch rear fitments in the staggered arrangement.
Choosing the right one starts with checking the wheel diameter on the car and whether it has the same size at all four corners or a front-and-rear split setup. A 19-inch LS500h and a 20-inch LS500h should not be treated the same during replacement, even though the overall tire diameters are very close.
What size rim does a 2020 Lexus LS500h use?
The 2020 Lexus LS500h uses either 19-inch or 20-inch rims, depending on configuration. The 245/50R19 tire fits a 19-inch rim, while both 245/45R20 and 275/40R20 fit 20-inch rims, with the wider 275/40R20 serving the rear position in the staggered 20-inch setup.
Wheel diameter should be confirmed before looking at tire brands or sidewall styles, because a tire intended for a 19-inch rim cannot be mounted on a 20-inch wheel. It also helps to confirm wheel width, especially on 20-inch applications where front and rear tires may use different width ranges and different section widths.
Why does the 2020 Lexus LS500h have more than one tire size?
More than one tire size appears on the 2020 Lexus LS500h because the car was fitted with more than one wheel arrangement. One setup uses 245/50R19, while another uses 20-inch tires, including a staggered combination with 245/45R20 in front and 275/40R20 at the rear.
That means tire replacement should follow the actual wheels and axle positions on the car rather than the model name alone. Looking at the tire sidewall already mounted, confirming the rim diameter, and checking whether the rear tires are wider than the fronts will usually clarify which LS500h configuration is being serviced.
Choosing the Right Tire
What should I consider when choosing a 2020 Lexus LS500h tire?
Start with the correct size for the actual wheel setup, because the 2020 Lexus LS500h may use 245/50R19, 245/45R20, or 275/40R20. After size is confirmed, compare construction, rim-width compatibility where stated, sidewall style, tire series, and any load figure that accompanies the product specifications.
The next choice is more about how the car is used and how it should look. A blackwall tire gives a more understated presentation, while redline or raised white letter options create a stronger visual statement on 20-inch fitments. Matching the intended use and appearance matters just as much as staying with the correct size.
What sidewall styles are available for 2020 Lexus LS500h tires?
Sidewall styling for the 2020 Lexus LS500h includes blackwall, redline, and RWL options, depending on tire size. Blackwall choices appear across all three primary sizes, while redline and raised white letter offerings show up in the 20-inch 245/45R20 and 275/40R20 fitments through the Pro-Trac Street Pro III line.
That gives the LS500h owner a clear appearance decision once fitment is confirmed. A blackwall tire keeps the look clean and contemporary, while redline or RWL can add a more custom or performance-flavored presentation. Sidewall style should be chosen only after confirming the vehicle's exact size and axle position.
What brands offer tires for the 2020 Lexus LS500h?
Tires for the 2020 Lexus LS500h are available from BFGoodrich, Nitto, Pro-Trac, and M&H Racemaster, depending on size. BFGoodrich appears across all three fitments, Nitto is available in the 20-inch sizes, Pro-Trac offers redline and RWL choices in 20-inch applications, and M&H Racemaster appears in 275/40R20.
Brand choice should be considered alongside tire series, sidewall treatment, and the actual role of the tire on the car. A front 245/45R20, a rear 275/40R20, and a 19-inch 245/50R19 each present different comparison points, so it helps to narrow the search by size before weighing brand differences.
Restoration & Appearance
Which tire should I choose for a period-style 2020 Lexus LS500h?
A period-style approach on a 2020 Lexus LS500h still begins with the correct modern radial size for the wheel package on the car. Among the available options, blackwall tires keep the appearance closest to the restrained luxury-sedan look most buyers associate with a contemporary LS, while 20-inch Pro-Trac options add more visual emphasis.
The right choice depends on whether the goal is subtle factory-inspired presentation or a more personalized look. On a car that already wears 20-inch wheels, redline or raised white letter sidewalls will stand out more noticeably. Keeping the correct front and rear size relationship matters more than pursuing a visual theme alone.
How does tire construction affect the appearance of a restored 2020 Lexus LS500h?
Construction is straightforward on the 2020 Lexus LS500h because the primary fitments here are all radial. That means the visual difference comes less from bias-ply versus radial choice and more from sidewall treatment, tire series, and whether the car is on a 19-inch single-size setup or a 20-inch staggered arrangement.
Appearance can change noticeably when the sidewall style changes from blackwall to redline or raised white letter, especially on the 20-inch fitments. For an owner preserving a factory-inspired look, matching the wheel setup already on the vehicle and choosing a restrained sidewall is usually the cleaner path.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2020 Lexus LS500h?
Yes, modifications can affect tire fitment on a 2020 Lexus LS500h even when the tire size itself is correct. Aftermarket wheels, changes in wheel width, altered offset, suspension lowering, or body and brake changes can all influence how a 245/50R19, 245/45R20, or 275/40R20 tire sits on the car.
Any LS500h that has been changed from its original wheel or suspension setup should be checked for clearance at full steering lock and through suspension travel. It also helps to confirm whether the car still uses a staggered front-and-rear arrangement, since mixing those positions incorrectly can create avoidable fitment issues.
What should I inspect before driving a 2020 Lexus LS500h on new tires?
Before driving a 2020 Lexus LS500h on new tires, inspect wheel condition, confirm the tire sizes match the actual wheel positions, and verify inflation pressure is set appropriately for the installed tires and vehicle use. It is also wise to check for any rubbing, uneven mounting, visible sidewall damage, or air loss after installation.
A short initial road test can reveal vibration, steering pull, or clearance problems that are easier to address early. On a staggered 20-inch car, double-check that the 245/45R20 tires remain at the front and the 275/40R20 tires remain at the rear, since the setup depends on that front-to-rear distinction.
How often should tires on a 2020 Lexus LS500h be inspected?
Tires on a 2020 Lexus LS500h should be inspected regularly for pressure loss, tread wear, cuts, bulges, and sidewall cracking, even if the car is not driven often. Low-use luxury cars can age tires quietly, so condition matters just as much as mileage on 245/50R19, 245/45R20, and 275/40R20 fitments.
Monthly visual checks are a sensible routine, with a closer inspection before longer trips or seasonal use. Any LS500h fitted with 20-inch staggered tires also benefits from periodic confirmation that wear remains consistent front to rear, since the front and rear positions use different sizes and should not be evaluated as interchangeable.
