The 2019 Lexus LC500h blends grand touring luxury with hybrid performance in a way that makes wheel and tire choice part of the car’s overall character. Its long, low proportions and staggered setup mean tire fitment is not a simple one-size decision. This model uses modern radial tires in a front-and-rear stagger, with either 20-inch or 21-inch rim diameters depending on the wheel package. That also means the buying decision centers on confirming the wheel diameter first, then selecting the right front and rear sizes, sidewall treatment, and tire series. For owners focused on appearance, road manners, or maintaining the intended stance, matching the exact setup matters.
Which Tire Size Is Right for The 2019 Lexus LC500h
The 2019 Lexus LC500h uses four primary tire sizes because it has a staggered front-and-rear setup and comes with either 20-inch or 21-inch wheels. The first step is confirming which rim diameter is on the car, since the front and rear sizes change together with the wheel package. Once that is settled, the decision becomes selecting the right radial tire in the correct front and rear combination and comparing the available brands, tire series, and sidewall styles where products are offered.
245/40R21 is a modern metric radial size in which 245 identifies the nominal section width in millimeters, 40 is the aspect ratio, R indicates radial construction, and 21 is the rim diameter in inches. On the 2019 Lexus LC500h, this is a front tire size used with the 21-inch wheel setup. Its role is tied to the staggered fitment, so it should be matched with the correct rear companion size rather than treated as a standalone selection. Owners should confirm the actual wheel package on the car before replacing tires, especially if wheels have ever been changed.
245/45R20 is a metric radial size that uses a 245-millimeter nominal width, a 45-series profile, and a 20-inch rim diameter. On the 2019 Lexus LC500h, it serves as the front tire size for the 20-inch staggered setup. Available choices in this size include BFGoodrich, Nitto, and Pro-Trac offerings, with blackwall, redline, and raised white letter sidewall treatments across series such as g-Force Sport Comp 2, g-Force Comp 2 AS, g-Force Phenom T/A, Nitto NT555 G2, and Street Pro III. It is the key front size to verify when replacing tires on a 20-inch-wheel LC500h.
275/35R21 is a modern metric radial size with a 275-millimeter nominal section width, a 35-series profile, and a 21-inch rim diameter. On the 2019 Lexus LC500h, this is the rear tire size paired with the 21-inch front fitment. The wider rear sizing is part of the car’s staggered layout, so it needs to be matched to the correct front size and wheel diameter rather than mixed with the 20-inch package. Buyers should verify that the rear wheels are truly 21-inch wheels and check for any suspension or wheel changes before choosing replacement tires.
275/40R20 is a metric radial size that combines a 275-millimeter nominal width with a 40-series profile on a 20-inch rim. On the 2019 Lexus LC500h, it is the rear tire size used with the 20-inch wheel package. Product choices in this size include BFGoodrich, Nitto, Pro-Trac, and M&H Racemaster, with blackwall, redline, and raised white letter options across several series. Because this rear size works as part of a staggered setup, the practical step is confirming the car’s complete 20-inch front-and-rear combination before selecting a tire style or series.
Fitment on the 2019 Lexus LC500h is straightforward once the front-versus-rear layout and wheel diameter are confirmed. The covered sub-model positions use a staggered setup, so checking whether you are replacing a front or rear tire matters just as much as confirming 20-inch or 21-inch wheels.

2019 Lexus LC500h Base Front
The 2019 Lexus LC500h Base Front uses a radial front tire in either the 20-inch or 21-inch fitment, depending on the wheel package installed on the car. That means front tire selection starts with confirming wheel diameter, then choosing among the available radial tire options that suit the car’s intended appearance and road use.
The 2019 Lexus LC500h Base Rear uses the wider rear portion of the staggered radial setup, again in either a 20-inch or 21-inch wheel configuration. Rear tire choice should stay matched to the correct front-and-rear package, with attention to wheel diameter and any changes that may have been made to the wheels or suspension.
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.

Owners researching 2019 Lexus LC500h tires usually need to sort out the staggered front-and-rear sizes, confirm 20-inch versus 21-inch wheels, and compare the available radial tire styles, brands, and fitment considerations before putting the car back on the road.
Tire Size & Fitment
What tire size fits a 2019 Lexus LC500h?
The 2019 Lexus LC500h uses a staggered tire setup, not one square size at all four corners. Front sizes are 245/45R20 or 245/40R21, and rear sizes are 275/40R20 or 275/35R21, all in radial construction. The 20-inch sizes belong together, and the 21-inch sizes belong together as their own package.
The practical first step is checking the wheel diameter actually on the car before ordering replacements. Once the wheel package is confirmed, make sure the front and rear sizes stay properly matched, since mixing the 20-inch and 21-inch combinations would create fitment problems and change the intended staggered setup.
What size rim does a 2019 Lexus LC500h use?
A 2019 Lexus LC500h uses either 20-inch or 21-inch rims, depending on the wheel setup. The 20-inch arrangement uses 245/45R20 in front and 275/40R20 in the rear, while the 21-inch arrangement uses 245/40R21 in front and 275/35R21 in the rear. All of these are radial tire fitments.
Rim diameter should be confirmed directly from the wheel before selecting tires, especially on a car that may have had aftermarket wheels installed. A quick diameter check prevents ordering the right width and profile in the wrong rim size, which is the most important fitment distinction on this LC500h.
Why does the 2019 Lexus LC500h have more than one tire size?
The 2019 Lexus LC500h has more than one tire size because it uses a staggered front-and-rear arrangement and appears with two different wheel diameters. The front tires are narrower than the rear tires, and each wheel package has its own matching pair of front and rear sizes. That creates four primary sizes across the full model coverage.
For tire replacement, that means the question is not simply which single size fits the car. The important step is identifying whether the car has the 20-inch or 21-inch package, then choosing the correct front size and correct rear size within that specific setup so the staggered fitment remains consistent.
Choosing the Right Tire
What should I consider when choosing a 245/45R20 or 275/40R20 tire for a 2019 Lexus LC500h?
Start with the correct position and wheel package, since 245/45R20 is the front size and 275/40R20 is the rear size for the 20-inch setup on the 2019 Lexus LC500h. From there, compare radial tire series, brand, sidewall style, and rim-width specifications where they are stated. Those details shape the character of the available choices within the correct size.
BFGoodrich, Nitto, Pro-Trac, and M&H Racemaster options cover different use cases and visual styles, including blackwall, redline, and raised white letter treatments. It also helps to compare load figures and construction details where available, while keeping the front and rear selections coordinated as a matched 20-inch staggered set.
What sidewall styles are available for 2019 Lexus LC500h tires?
For the available 20-inch LC500h sizes, sidewall choices include blackwall, redline, and RWL, which is a raised white letter style. Those options appear in both the 245/45R20 front size and the 275/40R20 rear size. The sidewall treatment changes the look of the car without changing the basic size format.
Blackwall is the understated choice, while redline and raised white letter tires create a more expressive presentation. Since the LC500h uses a staggered setup, owners usually get the most coherent result by choosing the same sidewall style front and rear and confirming that the selected tires still match the car’s correct 20-inch fitment.
What brands offer tires for the 2019 Lexus LC500h?
Available 20-inch tires for the 2019 Lexus LC500h come from BFGoodrich, Nitto, Pro-Trac, and M&H Racemaster. Those brands appear across front 245/45R20 and rear 275/40R20 sizes, with several different radial series represented. The result is a mix of performance-oriented, appearance-focused, and specialty-style choices within the proper fitment range.
Brand comparison should come after the basic fitment decision, not before it. Once the correct front and rear sizes are confirmed, look at each brand’s tire series, sidewall styling, and any stated rim-width or load information so the final choice suits the car’s wheels, intended use, and overall visual direction.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2019 Lexus LC500h?
Yes, modifications can affect tire fitment on a 2019 Lexus LC500h even when the tire size itself is correct. Aftermarket wheels, altered wheel offsets, suspension changes, ride-height changes, or body modifications can all change the available space around the tire. That matters on a staggered car where front and rear sizes are already different by design.
Checking fitment on a modified LC500h means confirming more than the size code on the sidewall. Measure the actual wheel diameter, make sure width and offset are appropriate, and inspect steering, inner-fender, and suspension clearance before mounting replacement tires, especially when moving between old and new wheel-and-tire combinations.
What should I inspect before driving a 2019 Lexus LC500h on new tires?
Before driving a 2019 Lexus LC500h on new tires, confirm that the correct front and rear sizes were installed for the car’s 20-inch or 21-inch wheel package. Then check inflation pressure, bead seating, valve condition, and visible clearance around the suspension and fenders. A staggered setup deserves a careful final look at all four corners.
It also helps to inspect the wheels for damage and make sure the old tire wear pattern does not point to alignment or suspension issues. If the car has been stored or used infrequently, look over bushings and related components as well, since fresh tires can quickly reveal problems elsewhere in the chassis.
How often should tires on a 2019 Lexus LC500h be inspected?
Tires on a 2019 Lexus LC500h should be inspected regularly, with a quick visual check before routine driving and a more thorough inspection at normal service intervals or before longer trips. On a car with staggered fitment, the front and rear tires should each be checked for pressure, uneven wear, cuts, bulges, and signs of air loss.
Low-use luxury and performance cars can age their tires out before they wear them out, so condition matters as much as tread depth. Pay attention to sidewall cracking, flat spotting after storage, and any change in ride quality or steering feel, since those signs can point to a tire issue even when tread still looks acceptable.
