The 2019 Lexus LS500h sits at the intersection of flagship luxury and hybrid touring, blending the long-wheelbase presence of a full-size Lexus sedan with the quieter, efficiency-minded character expected of a modern LS. Tire fitment matters here because this model uses three radial sizes, with 19-inch and 20-inch applications depending on configuration and a staggered 20-inch setup on the F Sport. That creates a real choice between standard blackwall touring and performance-oriented options, plus more style-driven redline or raised white letter selections in the 20-inch sizes. The right pick starts with confirming the exact wheel setup, then matching the tire's appearance and driving purpose to the car.
Which Tire Size Is Right for The 2019 Lexus LS500h
The 2019 Lexus LS500h uses three primary tire sizes, and the right one depends on the exact sub-model and wheel setup. Two different rim diameters are involved, so the first step is confirming whether the car has 19-inch wheels or a 20-inch package. That matters most on F Sport models, where front and rear fitment can differ, while the Base model may use either a 19-inch or 20-inch size.
245/45R20 is a metric radial size with a 245-millimeter section width, a 45-series profile, radial construction, and a 20-inch rim diameter. On the 2019 Lexus LS500h, this size is used on 20-inch applications and also serves as the F Sport front fitment. Available choices include BFGoodrich, Nitto, and Pro-Trac products, with blackwall, redline, and RWL sidewall treatments depending on the tire series. This size is the right place to focus when the car has a 20-inch front setup and the goal is to balance correct fitment with either a more understated or more stylized look.
245/50R19 is a metric radial size that combines a 245-millimeter section width with a 50-series profile on a 19-inch wheel. For the 2019 Lexus LS500h, it applies to 19-inch Base-model fitment rather than the staggered F Sport arrangement. Product choices in this size center on BFGoodrich g-Force series tires, all in blackwall form, with some variation in rim-width range and load capacity details depending on the specific tire. This is the size to evaluate when the car retains its 19-inch wheel package and the priority is staying with the proper overall fitment for that setup.
275/40R20 is a wider metric radial size with a 275-millimeter section width, a 40-series profile, and a 20-inch rim diameter. On the 2019 Lexus LS500h, this size serves as the F Sport rear tire, making it part of the car's staggered 20-inch configuration rather than a universal fitment across the lineup. Choices include BFGoodrich, Nitto, M&H Racemaster, and Pro-Trac options, mostly in blackwall form but also with redline and RWL styles in the Street Pro III series. This size should be chosen only after confirming the car has the wider rear 20-inch wheel setup that matches the F Sport configuration.
Tire fitment varies across the covered 2019 Lexus LS500h sub-models, so identifying the exact configuration matters before choosing a size. The biggest distinction is between the Base model's wheel-package options and the F Sport's staggered front-and-rear setup.

2019 Lexus LS500h Base
The 2019 Lexus LS500h Base uses either a 245/50R19 radial or a 245/45R20 radial, depending on the wheel package installed on the car. That makes wheel-diameter confirmation the key first step, followed by choosing among the available blackwall or, on the 20-inch size, more appearance-oriented sidewall options.
The 2019 Lexus LS500h F Sport Front uses a 245/45R20 radial tire as part of the model's 20-inch staggered arrangement. Tire selection here should stay focused on the proper front size while also matching the rear fitment and the intended mix of performance character and visual style.
The 2019 Lexus LS500h F Sport Rear uses a wider 275/40R20 radial tire to complete the staggered 20-inch F Sport setup. That means the rear tire should be selected with the correct width and wheel compatibility in mind, rather than treated as interchangeable with the front 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.

These FAQs focus on the tire-size decisions that matter most for a 2019 Lexus LS500h, including 19-inch versus 20-inch fitment, the F Sport staggered setup, available tire styles, and the checks worth making before regular road use.
Tire Size & Fitment
What tire size fits a 2019 Lexus LS500h?
The 2019 Lexus LS500h uses three primary tire sizes: 245/50R19, 245/45R20, and 275/40R20. The Base model may use either 245/50R19 or 245/45R20 depending on wheel package, while the F Sport uses a staggered 20-inch setup with 245/45R20 in front and 275/40R20 in the rear.
Choosing the right size starts with confirming the exact sub-model and wheel diameter on the car. A 19-inch Base setup and a 20-inch Base setup do not use the same tire, and the F Sport front and rear are not the same size. Checking the wheel markings and the current tire sidewall is the safest first step before comparing product options.
What size rim does a 2019 Lexus LS500h use?
The 2019 Lexus LS500h uses either a 19-inch or 20-inch rim depending on configuration. The 245/50R19 size is mounted on a 19-inch wheel, while both 245/45R20 and 275/40R20 are 20-inch tires used on 20-inch wheels.
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 also true. On F Sport models, wheel width also becomes part of the conversation because the wider 275/40R20 rear tire belongs on the rear wheel position, not simply any 20-inch rim.
Why does the 2019 Lexus LS500h have more than one tire size?
More than one tire size appears on the 2019 Lexus LS500h because the model was offered with different wheel packages, and the F Sport uses a staggered arrangement. The Base model may carry either a 19-inch or 20-inch fitment, while the F Sport splits front and rear sizing between 245/45R20 and 275/40R20.
That means tire selection is not just about the model name on the trunk. The actual wheel package on the car determines whether a 19-inch or 20-inch tire is needed, and the F Sport requires position-specific matching. Anyone replacing one tire or a pair should confirm all four current sizes before ordering or mounting replacements.
Choosing the Right Tire
What should I consider when choosing a 245/45R20 tire for a 2019 Lexus LS500h?
A 245/45R20 tire for a 2019 Lexus LS500h should first match the correct 20-inch application, whether that is a Base model with 20-inch wheels or the front position on an F Sport. Once size is confirmed, the main comparison points are tire series, brand, sidewall style, and the rim-width specifications attached to each product.
Available choices in this size include blackwall, redline, and RWL sidewall treatments, so appearance can be part of the decision along with intended use. It also helps to compare load figures where shown and check that the wheel width falls within the tire's approved range. That keeps the selection grounded in both fitment and the look the car is meant to carry.
What sidewall styles are available for 2019 Lexus LS500h tires?
Sidewall style depends on the tire size chosen for the 2019 Lexus LS500h. Blackwall options are available across all three primary sizes, while the 20-inch sizes 245/45R20 and 275/40R20 also include redline and RWL versions in the Pro-Trac Street Pro III series.
That gives a buyer two different directions: a more understated modern look with blackwalls, or a more distinctive presentation with redline or raised white letter styling. Since the 19-inch 245/50R19 selection stays within blackwall options, sidewall appearance is a bigger decision on the 20-inch fitments. The best choice depends on whether the car is being kept visually subtle or given a more expressive look.
What brands offer tires for the 2019 Lexus LS500h?
Tires for the 2019 Lexus LS500h are available from BFGoodrich, Nitto, Pro-Trac, and M&H Racemaster, depending on size. BFGoodrich appears across all three primary sizes, Nitto is available in both 20-inch sizes, Pro-Trac covers the 20-inch fitments with stylized sidewalls, and M&H Racemaster appears in the 275/40R20 rear size.
Brand choice should still come after confirming the correct size and wheel setup. Some brands are represented through several series within a size, while others appear in more specialized applications or sidewall treatments. Comparing by size, series, and sidewall style is more useful than choosing strictly by brand name, especially on a model with both standard and staggered fitments.
Restoration & Appearance
Which tire should I choose for a period-style 2019 Lexus LS500h?
A period-style approach on a 2019 Lexus LS500h starts by keeping the exact size that matches the car's original wheel setup, then choosing a tire whose sidewall presentation suits the look you want. Blackwall tires maintain the most contemporary luxury-sedan appearance, while redline or RWL options in the 20-inch sizes create a more custom visual statement.
Because this is a modern flagship sedan rather than a vintage restoration, appearance choices are more about preserving the car's intended character than chasing historical tire authenticity. The key is avoiding a visual mismatch between front and rear on staggered F Sport cars and making sure any style-driven choice still matches the correct size, wheel diameter, and approved application.
How does tire construction affect the appearance of a restored 2019 Lexus LS500h?
Tire construction is straightforward on the 2019 Lexus LS500h because its primary fitments are radial. That means the appearance decision comes less from bias-ply versus radial construction and more from tread and sidewall presentation, especially when comparing standard blackwalls with redline or RWL choices in the 20-inch sizes.
For a clean, original-feeling luxury-sedan look, many owners stay with blackwall radials that do not call attention to the tire itself. A more personalized approach can lean toward redline or raised white letter styling, particularly on 20-inch applications. Either way, keeping the proper front and rear sizes and the correct wheel diameter matters more than chasing a style that does not match the car's actual setup.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2019 Lexus LS500h?
Yes, modifications can affect tire fitment on a 2019 Lexus LS500h even when the tire size itself is correct. Aftermarket wheels, changes in wheel width, altered offset, suspension lowering, or body modifications can all change how a 245/50R19, 245/45R20, or 275/40R20 tire sits in relation to fenders and steering components.
That is especially important on F Sport models because the staggered setup already uses different front and rear sizes. A modified car should be checked for full steering clearance, rear clearance under load, and wheel compatibility before replacement tires are mounted. Looking only at the sidewall size without checking the actual wheel and suspension setup can lead to avoidable fitment problems.
What should I inspect before driving a 2019 Lexus LS500h on new tires?
Before driving a 2019 Lexus LS500h on new tires, inspect the tire size, wheel position, air pressure, and overall condition of the installation. On F Sport cars, make sure the 245/45R20 front tires and 275/40R20 rear tires are in the correct positions. It also helps to confirm that the tires seat properly on the wheels and that no rubbing appears at full steering lock.
A short initial road test should include listening for contact noises and checking for vibration, pull, or unusual behavior. After a brief drive, recheck inflation and visually inspect the sidewalls and tread shoulders. Since this model may use either 19-inch or 20-inch fitment depending on configuration, a final walk-around to confirm every wheel carries the correct size is worth the extra minute.
How often should tires on a 2019 Lexus LS500h be inspected?
Tires on a 2019 Lexus LS500h should be inspected regularly, not just when tread looks worn. A practical routine is to check pressure and visible condition at least monthly and before longer drives. Look for uneven wear, cuts, punctures, sidewall damage, or signs that the tire may be losing air.
Regular inspection matters even more on cars that are driven infrequently, because aging and underinflation can develop without obvious warning. On staggered F Sport setups, front and rear tires should be checked as separate fitments rather than treated as interchangeable. Catching a pressure issue, damaged sidewall, or unusual wear pattern early helps protect both ride quality and the wheel-and-tire package.
