The 2020 Lexus LC500 blends grand touring refinement with dramatic coupe styling, making tire selection a real part of preserving the car’s balance and stance. Its fitment is also unusually specific because the LC500 uses a staggered front-and-rear setup, with either 20-inch or 21-inch radial tire combinations depending on configuration. Front sizes are 245/45R20 or 245/40R21, while rear sizes are 275/40R20 or 275/35R21. Available choices include blackwall performance radials along with redline and raised white letter options in the 20-inch sizes. The key is matching the exact wheel diameter and axle position before comparing series, sidewall style, and intended use.
Which Tire Size Is Right for The 2020 Lexus LC500
The 2020 Lexus LC500 uses four primary tire sizes across a staggered radial setup, and the correct choice depends first on wheel diameter and whether the tire is for the front or rear. Some LC500 configurations use 20-inch wheels, while others use 21-inch wheels, so identifying the exact setup on the car is more important than comparing tread style or brand first.
245/40R21 is a metric radial size in which 245 identifies nominal section width in millimeters, 40 is the aspect ratio, R denotes radial construction, and 21 is the wheel diameter in inches. On the 2020 Lexus LC500, this size serves the front position on 21-inch-wheel configurations. It is part of the car’s staggered fitment strategy, so it needs to be matched with the correct rear size rather than treated as a stand-alone selection. This is the size to evaluate when the car already carries 21-inch front wheels and the goal is to preserve the intended wheel-and-tire relationship.
245/45R20 is a metric radial size that uses a 245-millimeter nominal section width, a 45-series profile, and a 20-inch rim diameter. On the 2020 Lexus LC500, it is the front tire size for 20-inch-wheel applications. Available choices in this size include BFGoodrich, Nitto, and Pro-Trac offerings, with blackwall, redline, and raised white letter sidewall styles depending on the tire series. This size deserves close attention if the car is equipped with 20-inch front wheels and the buyer wants to compare a more contemporary blackwall presentation against a more distinctive sidewall treatment.
275/35R21 is a metric radial size where 275 indicates nominal section width in millimeters, 35 is the aspect ratio, R marks radial construction, and 21 identifies the wheel diameter. On the 2020 Lexus LC500, this is the rear size used with the 21-inch staggered setup. Its role is specific to the rear axle, so it should be chosen as part of the complete 21-inch front-and-rear package rather than mixed casually with another diameter. This is the size to confirm when the LC500 carries 21-inch rear wheels and the owner wants to maintain the proper staggered relationship.
275/40R20 is a metric radial size with a 275-millimeter nominal section width, a 40-series profile, and a 20-inch rim diameter. On the 2020 Lexus LC500, it serves the rear position on 20-inch-wheel cars. Product choices in this size span BFGoodrich, Nitto, M&H Racemaster, and Pro-Trac, with blackwall, redline, and raised white letter options plus several distinct tire series. This is the rear size to compare when the car uses 20-inch wheels and the decision involves not only fitment, but also whether the tire’s appearance and intended use suit the way the car is driven.
Sub-model fitment on the 2020 Lexus LC500 is tied closely to front-versus-rear position and wheel diameter. Checking the exact configuration matters because some versions use the 20-inch staggered set, while the Inspiration Series uses the 21-inch front and rear combination.

2020 Lexus LC500 Base Front
The 2020 Lexus LC500 Base Front uses either a 245/45R20 or 245/40R21 radial, depending on which wheel package is on the car. That makes wheel-diameter confirmation the first step before comparing brands, sidewall styles, or tire series in the front position.
The 2020 Lexus LC500 Base Rear uses either a 275/40R20 or 275/35R21 radial to match the corresponding front setup. Rear tire selection should stay tied to the wheel diameter already on the car so the staggered fitment remains consistent from front to rear.
The 2020 Lexus LC500 Inspiration Series Front uses the 245/40R21 radial size. For this configuration, the choice is less about alternate fitments and more about confirming the 21-inch setup and matching the tire to the car’s intended road use and overall presentation.
The 2020 Lexus LC500 Inspiration Series Rear uses the 275/35R21 radial size. Tire selection here should focus on preserving the correct rear size for the 21-inch staggered arrangement rather than substituting another diameter or profile without a full wheel-and-clearance check.
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)

Tire Size & Fitment
What tire size fits a 2020 Lexus LC500?
The 2020 Lexus LC500 uses a staggered tire setup with different sizes front and rear. Front fitments are 245/45R20 or 245/40R21, while rear fitments are 275/40R20 or 275/35R21, and all are radial sizes.
The important next step is confirming both wheel diameter and axle position before choosing a tire. A front size should be matched to the correct rear size for the same 20-inch or 21-inch configuration, especially on a car like the LC500 where the stance and fitment depend on that staggered relationship.
What size rim does a 2020 Lexus LC500 use?
A 2020 Lexus LC500 uses either 20-inch or 21-inch rims, depending on the configuration. The 245/45R20 and 275/40R20 sizes mount on 20-inch wheels, while the 245/40R21 and 275/35R21 sizes are matched to 21-inch wheels.
Rim diameter is the first thing to verify because the LC500 does not use one universal wheel size across every setup. Checking the wheel itself before ordering tires helps avoid mixing a 20-inch front-and-rear package with 21-inch sizes that belong to a different configuration.
Why does the 2020 Lexus LC500 have more than one tire size?
The 2020 Lexus LC500 has more than one tire size because it uses a staggered arrangement and appears with both 20-inch and 21-inch wheel packages. That means the front and rear sizes differ, and the wheel diameter also changes between configurations.
This is normal for a performance-oriented grand touring coupe, but it makes fitment more specific than on a square setup. The practical takeaway is to identify the exact wheel package already on the car and then select the matching front and rear sizes instead of assuming every LC500 uses the same combination.
Choosing the Right Tire
What should I consider when choosing a 2020 Lexus LC500 tire?
Start with the exact size, wheel diameter, and axle position, because a 2020 Lexus LC500 uses different front and rear tires and may have either 20-inch or 21-inch wheels. From there, compare radial construction, tire series, sidewall style, and any rim-width specifications that apply to the size you need.
The right choice depends on how the car is used and how you want it to look. Some 20-inch options lean toward a conventional blackwall performance appearance, while others offer redline or raised white letter styling, so the best comparison is between tires that already match the correct LC500 fitment.
What sidewall styles are available for 2020 Lexus LC500 tires?
For the 20-inch LC500 sizes, available sidewall styles include blackwall, redline, and RWL, which is raised white letter. Those choices appear in both 245/45R20 front and 275/40R20 rear applications, depending on the tire series selected.
Sidewall style changes the visual character of the car even when the size stays correct. Blackwall keeps the presentation more understated, while redline and raised white letters add a more expressive look, so it makes sense to choose the sidewall treatment only after confirming the proper front or rear size.
What brands offer tires for the 2020 Lexus LC500?
Available 20-inch tires for the 2020 Lexus LC500 come from BFGoodrich, Nitto, Pro-Trac, and M&H Racemaster. The assortment includes several radial series, such as g-Force Sport Comp 2, g-Force Comp 2 AS, g-Force Phenom T/A, Nitto NT555 G2, Street Pro III, and a Drag Radial option.
Brand should be part of the comparison, but not the only factor. Once the correct LC500 size is confirmed, it helps to compare each tire’s intended character, sidewall style, and wheel-fit specifications so the final choice suits both the car’s setup and the way it will be driven.
Restoration & Appearance
Which tire should I choose for a period-style 2020 Lexus LC500?
A period-style approach on a 2020 Lexus LC500 starts with keeping the correct staggered size and wheel diameter already used on the car. From there, the available 20-inch radial choices create different visual effects, especially where blackwall, redline, and raised white letter versions are offered.
For an appearance-led selection, sidewall treatment usually matters more than chasing unnecessary size changes. Matching the front and rear tires to the existing 20-inch or 21-inch setup preserves the LC500’s proportions, while the final style choice depends on whether the goal is subtle presentation or a more assertive custom look.
How does tire construction affect the appearance of a restored 2020 Lexus LC500?
On the 2020 Lexus LC500, primary fitment is radial throughout, so appearance differences come less from bias-ply versus radial decisions and more from profile, sidewall treatment, and overall tire character within the correct size. Blackwall, redline, and raised white letter options can each change the car’s visual tone.
That means appearance should be judged within the proper staggered fitment rather than by forcing a non-matching size. Keeping the correct front and rear dimensions helps the coupe retain its intended stance, while the chosen sidewall style lets the owner move the presentation toward understated, sporty, or more custom-oriented territory.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2020 Lexus LC500?
Yes, modifications can affect tire fitment on a 2020 Lexus LC500 even when the tire size seems close to stock. Aftermarket wheels, changes in wheel width, altered offset, suspension changes, or lowering can all influence how a staggered front-and-rear setup sits and clears the body.
That is especially important on a low, tightly packaged coupe using 20-inch or 21-inch wheels. Any car with non-original wheels or suspension should have its current setup checked carefully before selecting tires, including wheel diameter, tire clearance at full steering lock, and rear-space consistency under load.
What should I inspect before driving a 2020 Lexus LC500 on new tires?
Before driving a 2020 Lexus LC500 on new tires, inspect basic wheel and tire condition along with the car’s current setup. Check that the front and rear sizes are installed in the proper positions, then look over inflation pressure, visible damage, valve stems, and any signs of rubbing or uneven clearance.
A short recheck after the first miles is also worthwhile because a staggered performance fitment can reveal issues quickly if something is mismatched. Watching for vibration, irregular wear, air loss, or contact marks helps confirm that the wheel-and-tire combination is seated properly and behaving as expected on the road.
What should I check before a longer drive in a 2020 Lexus LC500?
Before a longer drive, make sure the 2020 Lexus LC500 has the correct front and rear tire sizes for its wheel package and that all four tires are in sound condition. Check pressure, tread condition, cuts, bulges, cracking, and any uneven wear that could suggest alignment or suspension concerns.
It also helps to confirm that the wheels are free of damage and that no recent changes have altered clearance. A longer trip puts more heat and sustained load into the tires, so catching slow air loss, rubbing, or age-related deterioration beforehand is especially important on a staggered high-performance setup.
