The 2019 Lexus LC500 blends grand touring comfort with a dramatic coupe shape and a naturally aspirated V8, making it a modern performance car that still feels special in collector and enthusiast circles. Tire fitment matters because this car uses a staggered radial setup, with different front and rear sizes and either 20-inch or 21-inch wheel diameters depending on the wheel package. That makes the first decision less about brand loyalty and more about confirming the exact front and rear size pair on the car. From blackwall performance radials to redline and raised white letter alternatives in the 20-inch sizes, the right choice depends on wheel diameter, intended use, and visual preference.
Which Tire Size Is Right for The 2019 Lexus LC500
The 2019 Lexus LC500 uses four primary tire sizes, and the correct choice depends first on wheel diameter and position on the car. Front and rear fitment are staggered, with one pair for 20-inch wheels and another for 21-inch wheels. Before selecting tires, confirm whether the car is equipped with the 20-inch or 21-inch setup and make sure the front and rear sizes are matched correctly.
245/40R21 is a metric radial size where 245 is the nominal section width in millimeters, 40 is the aspect ratio, R indicates radial construction, and 21 is the wheel diameter in inches. On the 2019 Lexus LC500, this size serves as a front fitment on the 21-inch staggered setup. Its role is to pair with the corresponding wider rear tire rather than stand alone as a universal LC500 size. Choosing this size starts with confirming that the car actually has 21-inch front wheels and that the rear tire package matches the same wheel family.
245/45R20 is a metric radial size with a 245-millimeter nominal section width, a 45-series profile, and a 20-inch rim diameter. On the 2019 Lexus LC500, it is the front tire size for the 20-inch staggered setup. Available choices in this size include BFGoodrich, Nitto, and Pro-Trac products, with blackwall, redline, and raised white letter sidewall treatments across several series. This size is the one to evaluate if the car wears 20-inch front wheels and the goal is to balance appearance, brand preference, and intended road use.
275/35R21 is a metric radial size in which 275 refers to nominal section width in millimeters, 35 is the aspect ratio, and 21 identifies the wheel diameter. For the 2019 Lexus LC500, this is the rear size used with the 21-inch front and rear wheel package. Its wider footprint is part of the car's staggered arrangement, so it should be considered together with the matching front size rather than as an isolated fitment choice. Selecting it begins with verifying the rear wheel diameter and maintaining the correct front-to-rear pairing already on the car.
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 2019 Lexus LC500, it is the rear fitment for the 20-inch staggered setup. Product choices in this size include BFGoodrich, Nitto, M&H Racemaster, and Pro-Trac, with blackwall, redline, and raised white letter options depending on the tire series. This is the rear size to focus on when the car has 20-inch wheels and the buyer wants to compare performance-oriented tire lines with different appearance treatments.
Fitment on the 2019 Lexus LC500 is straightforward in one sense and critical in another: the car uses separate front and rear tire sizes. The key step is confirming whether the car has the 20-inch or 21-inch staggered setup before choosing tires for either position.

2019 Lexus LC500 Base Front
The 2019 Lexus LC500 Base Front uses one of two radial front sizes depending on wheel package, with a 20-inch option and a 21-inch option. That means front tire selection starts by verifying wheel diameter, then choosing a tire that matches the existing staggered setup and intended appearance.
The 2019 Lexus LC500 Base Rear uses one of two wider radial rear sizes, again tied to either the 20-inch or 21-inch wheel package. Rear tire choice should stay aligned with the front fitment already on the car so the staggered front-to-rear size relationship remains consistent.
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.

Available 20-inch LC500 tire choices span BFGoodrich, Nitto, Pro-Trac, and M&H Racemaster, with several series and sidewall treatments to compare. Blackwall performance radials dominate, while redline and raised white letter options add a more custom visual direction on the 20-inch front and rear sizes.
These FAQs focus on the 2019 Lexus LC500's staggered tire sizing, 20-inch versus 21-inch wheel fitment, radial tire selection, sidewall and brand choices in the available 20-inch sizes, and the checks worth making before regular road use.
Tire Size & Fitment
What tire size fits a 2019 Lexus LC500?
The 2019 Lexus LC500 uses a staggered radial tire setup, so front and rear sizes are different. The 20-inch package uses 245/45R20 in front and 275/40R20 in the rear, while the 21-inch package uses 245/40R21 in front and 275/35R21 in the rear.
That means there is not one universal tire size for every 2019 LC500. The most important step is confirming which wheel diameter is on the car and keeping the correct front and rear pairing together. If the car has been changed from its original wheel setup, check the actual wheel sizes on the vehicle before choosing replacement tires.
What size rim does a 2019 Lexus LC500 use?
The 2019 Lexus LC500 uses either 20-inch or 21-inch rims, depending on the wheel package. The 20-inch setup pairs 245/45R20 front tires with 275/40R20 rear tires, while the 21-inch setup pairs 245/40R21 front tires with 275/35R21 rear tires.
Rim diameter is the first fitment detail to verify because the tire sizes are tied directly to it. The LC500 also uses different front and rear widths, so matching only one tire size is not enough. Check both the front and rear wheel diameters on the car before comparing tire options, especially if aftermarket wheels are already installed.
Why does the 2019 Lexus LC500 have more than one tire size?
The 2019 Lexus LC500 has more than one tire size because it uses a staggered setup with narrower front tires and wider rear tires, and it was offered with either 20-inch or 21-inch wheel diameters. That creates two complete front-to-rear size combinations rather than one single fitment.
The practical takeaway is that tire selection starts with the car's exact wheel package, not just the model name. Once the wheel diameter is confirmed, the front and rear sizes should be chosen as a matched pair. Mixing 20-inch and 21-inch sizes or choosing only by section width can create an incorrect setup for the car.
Choosing the Right Tire
What should I consider when choosing 245/45R20 and 275/40R20 tires for a 2019 Lexus LC500?
Start with the correct front and rear pairing, since the 20-inch 2019 Lexus LC500 uses 245/45R20 in front and 275/40R20 in the rear. From there, compare tire construction, brand, tire series, sidewall style, and rim-width compatibility where that specification is given.
The available 20-inch options range from blackwall performance-oriented radials to redline and raised white letter choices that change the car's visual character. It also helps to compare product weight and load figures when they are shown. Choosing the right tire comes down to balancing the LC500's wheel setup, intended use, and the appearance you want the car to carry.
What sidewall styles are available for 2019 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 the 245/45R20 front size and the 275/40R20 rear size, giving the car either a more understated or more custom visual presentation.
Sidewall style does not change the basic size requirement, but it can change the car's overall look significantly. A blackwall tire keeps the appearance modern and subtle, while redline and raised white letter options make a stronger visual statement. The best approach is to choose the sidewall treatment after confirming the correct wheel diameter and front-to-rear size pairing.
What brands offer tires for the 2019 Lexus LC500?
The available 20-inch tire options for the 2019 Lexus LC500 include BFGoodrich, Nitto, Pro-Trac, and M&H Racemaster. Those brands appear across several series, including g-Force Sport Comp 2, g-Force Comp 2 AS, g-Force Phenom T/A, Nitto NT555 G2, Street Pro III, and Drag Radial.
Brand choice should come after confirming the LC500's actual wheel package and the correct front and rear sizes. From there, compare the type of tire each brand offers in that size, along with sidewall appearance and any rim-width details shown. That gives a more useful basis for selection than choosing by brand name alone.
Restoration & Appearance
Which tire should I choose for a period-style 2019 Lexus LC500?
A period-style approach on a 2019 Lexus LC500 usually starts with keeping the correct staggered size combination already tied to the car's 20-inch or 21-inch wheel package. For buyers focused on visual character, the 20-inch sizes offer more appearance-driven choices, including blackwall, redline, and raised white letter radials.
That makes wheel diameter an important part of the appearance decision, not just a fitment detail. A blackwall tire keeps the car closer to its contemporary grand touring look, while redline or raised white letter options push it in a more custom direction. If exact originality matters, compare any visual choice against model-specific references before finalizing the set.
How does tire construction affect the appearance of a restored 2019 Lexus LC500?
On the 2019 Lexus LC500, the primary fitment is radial, so the visual change comes less from construction type and more from tire style within that radial format. In the available 20-inch sizes, blackwall, redline, and raised white letter sidewalls create noticeably different looks even when the overall fitment remains the same.
That means appearance-minded owners should focus on size, stance, and sidewall presentation together. A plain blackwall keeps the profile cleaner and more understated, while redline and raised white letter treatments draw more attention to the wheel and tire package. The strongest result usually comes from choosing a sidewall style that suits the car's wheels and overall theme.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2019 Lexus LC500?
Yes, modifications can affect tire fitment on a 2019 Lexus LC500. Changes to wheel diameter, wheel width, offset, suspension height, or body clearance can alter how the original 245/45R20 and 275/40R20 or 245/40R21 and 275/35R21 combinations sit and function on the car.
Even when a tire size matches the nominal wheel diameter, an altered setup can create clearance issues at the fender, suspension, or steering components. That is especially important on a staggered car where front and rear fitment already differ. Any LC500 with aftermarket wheels or suspension changes should be measured at the vehicle before replacement tires are selected.
What should I inspect before driving a 2019 Lexus LC500 on new tires?
Before driving a 2019 Lexus LC500 on new tires, inspect wheel condition, confirm the front and rear sizes are installed in the correct positions, and verify inflation pressure. It is also worth checking for rubbing at full steering lock, adequate clearance around suspension components, and proper valve-stem and bead seating.
A short initial road test can reveal vibration, pull, or clearance issues before the car is driven harder or farther. Recheck pressure after the first drives and look over the sidewalls for any signs of contact. On a staggered performance coupe like the LC500, those basic checks help confirm that the tire and wheel package is working as intended.
How often should tires on a 2019 Lexus LC500 be inspected?
Tires on a 2019 Lexus LC500 should be inspected regularly, not just when tread looks low. Check them before longer drives and at routine intervals for pressure loss, uneven wear, cuts, punctures, bulges, and any sidewall damage that could affect road use.
Low-use performance cars can still develop tire issues from age, storage conditions, or sitting in one position for long periods. It is smart to inspect both the front and rear tires because the LC500 uses different sizes at each end, and wear patterns may not match. Consistent checks help catch problems early and preserve predictable road manners.
