The 2021 Lexus LC500h blends grand-touring luxury with hybrid performance in a way that makes tire fitment more than a simple replacement decision. Its low, sculpted body and staggered setup mean front and rear sizing must stay properly matched to the wheel package on the car. This model uses radial tires in either a 20-inch combination of 245/45R20 front and 275/40R20 rear or a 21-inch combination of 245/40R21 front and 275/35R21 rear. Available choices include blackwall, redline, and raised white letter styling in the 20-inch sizes. Before selecting tires, confirm whether the car has the 20-inch or 21-inch wheels and keep the intended appearance and road use in mind.
Which Tire Size Is Right for The 2021 Lexus LC500h
The 2021 Lexus LC500h uses four primary tire sizes because it has a staggered front-and-rear fitment in two different wheel packages. The first step is confirming whether the car is equipped with 20-inch or 21-inch wheels, since the front and rear sizes change together with rim diameter. Once that is settled, the real decision becomes choosing the right radial tire within the correct front and rear pair, including sidewall style and tire series where available.
245/40R21 is a metric radial size that uses a 245-millimeter nominal section width, a 40-series profile, and a 21-inch rim diameter. On the 2021 Lexus LC500h, this size serves the front position in the 21-inch staggered setup, so it needs to be matched with the corresponding rear size rather than selected on its own. Its role is tied to preserving the intended front-to-rear balance of the wheel package. Choose this size only after confirming the car is actually on 21-inch front wheels and has not been changed to a 20-inch package.
245/45R20 is a metric radial size with a 245-millimeter nominal width, a 45-series aspect ratio, and a 20-inch rim diameter. On the 2021 Lexus LC500h, it is the front tire size for the 20-inch staggered combination. This size has the broadest visible product variety here, with BFGoodrich, Nitto, and Pro-Trac options plus blackwall, redline, and RWL sidewall treatments across several tire series. It is the right front size to evaluate when the car wears 20-inch wheels and the goal is to compare both performance-oriented and appearance-driven choices.
275/35R21 is a metric radial size that combines a 275-millimeter nominal width with a 35-series profile on a 21-inch rim. On the 2021 Lexus LC500h, this is the rear tire size used with the 21-inch wheel package, so it belongs as part of the staggered 21-inch front-and-rear set rather than as a stand-alone substitute. The wider section reflects its rear fitment role on this vehicle. Use this size only after confirming the rear wheels are 21-inch wheels and the car has not been converted to the 20-inch configuration.
275/40R20 is a metric radial size with a 275-millimeter nominal width, a 40-series profile, and a 20-inch rim diameter. On the 2021 Lexus LC500h, it is the rear tire size paired with 245/45R20 fronts in the 20-inch staggered setup. Product choice is meaningful here, with BFGoodrich, Nitto, Pro-Trac, and M&H Racemaster offerings that vary by tire series, blackwall or specialty sidewall presentation, and rim-width specification. This is the rear size to compare when the car is equipped with 20-inch wheels and the goal is to keep the proper staggered relationship.
Fitment on the 2021 Lexus LC500h is straightforward once the front-versus-rear position and wheel diameter are confirmed. The covered sub-model entries separate the car into front and rear tire applications, so checking position matters just as much as checking whether the car wears 20-inch or 21-inch wheels.

2021 Lexus LC500h Base Front
The 2021 Lexus LC500h Base Front uses the narrower front tire in either the 20-inch or 21-inch staggered package. Tire selection here starts with confirming wheel diameter, then choosing among the available radial options that suit the car's intended look and driving use.
The 2021 Lexus LC500h Base Rear uses the wider rear tire that matches the same wheel package as the front. Rear tire selection should stay paired to the correct front setup, with attention to wheel diameter, tire series, and any sidewall styling preferences offered in the applicable 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)

Tire Size & Fitment
What tire size fits a 2021 Lexus LC500h?
The 2021 Lexus LC500h uses a staggered radial setup with two possible wheel packages. The 20-inch combination is 245/45R20 in front and 275/40R20 in the rear, while the 21-inch combination is 245/40R21 in front and 275/35R21 in the rear. That means there is not one universal single size for all four corners.
The important step is matching the front and rear sizes to the wheel package already on the car. A 20-inch front size should stay with the 20-inch rear size, and the same applies to the 21-inch pair. Before ordering, confirm actual wheel diameter and make sure the car has not been altered with aftermarket wheels or a mixed setup.
What size rim does a 2021 Lexus LC500h use?
A 2021 Lexus LC500h uses either 20-inch or 21-inch rims, depending on the wheel package on the car. The 20-inch setup pairs 245/45R20 fronts with 275/40R20 rears, and the 21-inch setup pairs 245/40R21 fronts with 275/35R21 rears. Both arrangements keep a staggered front-and-rear fitment.
Rim diameter is the first thing to verify because it determines the entire tire pairing. A 20-inch tire cannot be mounted on a 21-inch wheel, and switching between packages is more involved than changing one size. Check the wheel markings or measure the mounted wheel before selecting tires, especially if the car was purchased used or modified.
Why does the 2021 Lexus LC500h have more than one tire size?
The 2021 Lexus LC500h has more than one tire size because it uses a staggered setup and comes with two different wheel diameters. The front tires are narrower than the rear tires, and the exact dimensions change depending on whether the car has 20-inch wheels or 21-inch wheels. That creates four primary sizes across the full application.
For tire selection, that means the decision is not just about width or profile in isolation. The correct approach is to identify the wheel package first, then keep the proper front and rear pairing together. Mixing 20-inch and 21-inch fitments without a deliberate wheel change can create obvious mounting and compatibility problems.
Choosing the Right Tire
What should I consider when choosing a 245/45R20 tire for a 2021 Lexus LC500h?
Start with position and wheel package. On a 2021 Lexus LC500h, 245/45R20 is the front tire size for the 20-inch staggered setup, so it should be selected as part of the correct front-and-rear pairing. Available choices include radial options from BFGoodrich, Nitto, and Pro-Trac, with different tire series and sidewall treatments.
After confirming the size, compare the details that affect how the tire suits the car and the owner. Sidewall appearance, rim-width specification, load figures where shown, and tire series all help separate one option from another. It also helps to keep the rear tire choice in mind so the complete 20-inch setup stays consistent.
What sidewall styles are available for 2021 Lexus LC500h tires?
In the available 20-inch LC500h tire selection, sidewall styles include blackwall, redline, and RWL, which is raised white letter. Those choices appear in the 245/45R20 front size and the 275/40R20 rear size. Blackwall is the most common presentation, while redline and RWL offer a more pronounced visual statement.
Sidewall style is mainly an appearance decision, but it should still be made within the correct front-and-rear size pairing. A buyer aiming for a clean contemporary look may stay with blackwall, while a more distinctive presentation may point toward redline or raised white letter. Confirm that the chosen style is available in both matching 20-inch sizes before finalizing a set.
What brands offer tires for the 2021 Lexus LC500h?
The available 20-inch tire choices for the 2021 Lexus LC500h include BFGoodrich, Nitto, Pro-Trac, and M&H Racemaster. BFGoodrich appears across several g-Force series, Nitto offers the NT555 G2, Pro-Trac offers Street Pro III in multiple sidewall treatments, and M&H Racemaster appears in the 275/40R20 rear size.
Brand is only one part of the decision. It should be weighed alongside the correct size, the front or rear position, sidewall style, rim-width specification, and the overall character of the tire series. Comparing those details matters more than choosing by brand name alone, especially on a staggered setup that uses different front and rear dimensions.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2021 Lexus LC500h?
Yes. Modifications can affect tire fitment on a 2021 Lexus LC500h even when the tire size itself is one of the correct sizes for the model. Aftermarket wheels, changes in wheel width, offset differences, suspension lowering, and body or brake changes can all alter how a tire sits and clears the car at the front or rear.
That matters most on a staggered car with low-profile tires and two possible wheel diameters. A modified LC500h should be checked for wheel diameter, wheel width, steering clearance, suspension travel, and fender clearance before replacing tires. Even a correct nominal size should be verified against the actual wheel-and-suspension setup on the car.
What should I inspect before driving a 2021 Lexus LC500h on new tires?
Before driving a 2021 Lexus LC500h on new tires, inspect the wheel diameter and confirm that the front and rear sizes match the car's actual wheel package. It is also wise to look over wheel condition, valve stems, tread seating after installation, and inflation pressure. A staggered setup should be checked corner by corner rather than assumed.
A short follow-up inspection after initial road use is also helpful. Look for any rubbing marks, unusual air loss, vibration, or uneven contact that might point to a mounting, balancing, or clearance issue. Since this car can use either 20-inch or 21-inch packages, verifying that all four mounted tires belong to the same intended setup is especially important.
How often should tires on a 2021 Lexus LC500h be inspected?
Tires on a 2021 Lexus LC500h should be inspected regularly, especially if the car is driven seasonally or spends long periods parked. Check for pressure loss, tread wear, sidewall cuts, bulges, cracking, and any signs of contact with suspension or body components. Front and rear tires should be inspected with equal care because the sizes are different.
Frequent inspection helps catch issues before they become ride or clearance problems. A car with 20-inch or 21-inch low-profile tires can be more sensitive to underinflation and road damage than a taller-profile setup. After a wheel change, tire replacement, or suspension adjustment, an extra inspection is worthwhile to confirm everything still sits and wears as intended.
