The 2024 Lexus LC500 blends modern grand touring character with dramatic coupe styling, making tire selection more than a simple maintenance item. Its proportions, stance, and road-going personality depend on a staggered setup that supports both appearance and handling balance. This exact 2024 Lexus LC500 fitment uses radial tires in 245/40R21 up front and 275/35R21 in the rear, both on 21-inch rims. The key decision is less about choosing between primary sizes and more about keeping the front and rear positions correct while matching the car’s intended driving use. Owners should confirm wheel setup carefully before replacement, especially if the car has been modified from its original 21-inch arrangement.
Which Tire Size Is Right for The 2024 Lexus LC500
The 2024 Lexus LC500 uses two primary tire sizes, and both are part of a staggered radial fitment on 21-inch wheels. The first step is confirming position on the car, since the front uses 245/40R21 and the rear uses 275/35R21. Once that is clear, the real choice becomes selecting the right tire within each size while maintaining proper front-to-rear fitment and checking wheel compatibility if anything has been changed.
245/40R21 is a modern metric radial size in which 245 identifies the nominal section width in millimeters, 40 is the aspect ratio, R marks radial construction, and 21 is the rim diameter in inches. On the 2024 Lexus LC500, this size serves the front position in the staggered setup and helps preserve the car’s intended balance. Because it is part of a matched front-and-rear arrangement, it should be evaluated with the rear size rather than in isolation. This is the size to verify when replacing front tires or checking whether aftermarket front wheels still match the original fitment plan.
275/35R21 is a modern metric radial size that uses a wider 275-millimeter nominal section width, a 35-series profile, and a 21-inch rim diameter. On the 2024 Lexus LC500, this size belongs at the rear and works with the narrower front tire as part of the factory-style staggered arrangement. Its role is distinct from the front fitment, so it should not be treated as an interchangeable position with 245/40R21. This is the size to confirm when replacing rear tires, verifying a matched set, or checking whether altered wheels or suspension still leave adequate clearance.
Fitment on the 2024 Lexus LC500 is straightforward in one sense and position-specific in another. The covered front and rear sub-model entries use different tire sizes, so identifying whether the tire is for the front or rear of the car matters before making a selection.

2024 Lexus LC500 Base Front
The 2024 Lexus LC500 Base Front uses a dedicated front radial size, so the tire choice here is tied to the front axle rather than the car as a whole. That makes position accuracy important when replacing tires, especially on a staggered setup where front and rear sizes are intentionally different.
The 2024 Lexus LC500 Base Rear uses its own rear radial size, wider than the front fitment and specific to the back of the car. Tire selection here should focus on preserving the correct rear position fitment and confirming clearance if wheel or suspension changes have been made.
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.
Frequently Asked Questions
Owners of a 2024 Lexus LC500 usually need answers about its staggered tire sizing, 21-inch rim fitment, front-versus-rear selection, and what to inspect before putting the car back on the road after tire replacement or storage.
Tire Size & Fitment
What tire size fits a 2024 Lexus LC500?
The 2024 Lexus LC500 uses a staggered tire setup with 245/40R21 on the front and 275/35R21 on the rear. Both sizes are radial tires and both mount on 21-inch rims, but they are assigned to different positions on the car rather than used interchangeably.
That means the first step is confirming whether the tire being replaced is on the front or rear axle. A matched staggered layout is part of the LC500’s intended setup, so owners should also confirm the actual wheel arrangement on the car if aftermarket wheels, tire changes, or suspension modifications have been made.
What size rim does a 2024 Lexus LC500 use?
The primary tire fitment for the 2024 Lexus LC500 uses 21-inch rims at both ends of the car. The front tire size is 245/40R21 and the rear is 275/35R21, so the rim diameter remains the same even though the tire widths and profiles differ.
Rim diameter is only one part of the fitment picture, especially on a staggered car. Wheel width and the overall wheel setup still matter, so a 21-inch diameter alone does not confirm compatibility if the car has non-original wheels or if a replacement tire differs from the established front and rear sizing plan.
Why does the 2024 Lexus LC500 have more than one tire size?
The 2024 Lexus LC500 has more than one tire size because it uses a staggered arrangement. The front position takes 245/40R21, while the rear uses 275/35R21, creating separate fitments for the two axles rather than one universal size across the whole car.
For the owner, that means tire selection starts with axle position, not just year, make, and model. It is also important to preserve the intended front-to-rear pairing unless the car has been deliberately reconfigured, since wheel changes, spacer use, or suspension alterations can affect clearance and overall fitment.
Choosing the Right Tire
What should I consider when choosing a 245/40R21 or 275/35R21 tire for a 2024 Lexus LC500?
Start with the correct axle position. The 2024 Lexus LC500 uses 245/40R21 in front and 275/35R21 in the rear, so the right choice begins with matching the tire to its intended location on the car and keeping the radial construction consistent with the primary fitment.
Beyond size, compare the actual wheel setup on the vehicle and think about how the car is used. A grand touring coupe that sees regular road miles may call for a different tire emphasis than one driven occasionally, but either way the front and rear sizes should remain coordinated and clearance should be checked carefully.
How do I choose between the available 245/40R21 and 275/35R21 tires for a 2024 Lexus LC500?
The best way to compare available 245/40R21 and 275/35R21 tires for a 2024 Lexus LC500 is to begin with fitment correctness rather than appearance alone. Each size serves a different end of the car, so the choice should preserve the staggered arrangement and match the existing 21-inch wheel setup.
After that, focus on practical factors such as how the car is driven, whether a full set or a single axle is being replaced, and whether the vehicle still has its original wheel specifications. Replacing only one position may be straightforward, but the complete setup should still be reviewed as a coordinated front and rear package.
What rim-fitment details should I compare when choosing tires for a 2024 Lexus LC500?
For a 2024 Lexus LC500, the key rim-fitment detail is that both primary tire sizes use a 21-inch rim diameter. The front and rear tire sizes are different, so diameter consistency does not mean the whole wheel package is the same from end to end.
Owners should also compare the actual wheel dimensions on the car, especially if it has aftermarket wheels. Tire replacement becomes much easier when the existing setup is verified first, because staggered fitments can be affected by wheel width, offset, and the available room around suspension components and bodywork.
Restoration & Appearance
Does correct tire fitment matter for a 2024 Lexus LC500 restoration or preservation project?
Yes. Even though the 2024 Lexus LC500 is a modern car, correct tire fitment still matters for preservation-minded ownership because the car’s stance and overall presentation depend on its staggered 245/40R21 front and 275/35R21 rear setup. Keeping the intended size relationship helps maintain the visual balance designed into the car.
That does not mean every preserved example must be configured identically, but changes should be made carefully. Owners who want to keep the car close to its original appearance should verify wheel specifications and avoid assuming any 21-inch tire will create the same look once mounted on a different wheel package.
Which tire fitment approach best preserves the look of a 2024 Lexus LC500?
A preservation-oriented approach starts by retaining the LC500’s staggered radial sizing: 245/40R21 in front and 275/35R21 in the rear. That combination supports the car’s intended proportions and keeps the visual relationship between the front and rear of the body from being altered by an arbitrary tire change.
Appearance is affected by more than the sidewall numbers, so owners should also confirm the actual wheel setup before replacing tires. A different offset, wheel width, or altered suspension can change how the car sits, making a correct-size tire look different than expected even when the basic diameter remains 21 inches.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2024 Lexus LC500?
Yes. Modifications can affect tire fitment on a 2024 Lexus LC500 even when the replacement tire still reads 245/40R21 or 275/35R21. Aftermarket wheels, suspension changes, spacers, or altered ride height can all change how much room the tire has at the fender, steering components, or suspension.
That is why the actual setup on the car should be checked before replacement rather than relying only on factory-style size information. Position matters on a staggered fitment, and even a correct nominal size deserves a clearance review if the car no longer uses its original wheel and suspension arrangement.
What should I inspect before driving a 2024 Lexus LC500 on new tires?
Before driving a 2024 Lexus LC500 on new tires, verify that the front tires are 245/40R21 and the rear tires are 275/35R21, and confirm that each tire is seated properly on the 21-inch wheel. It is also wise to check inflation, valve condition, and overall visual uniformity across the staggered setup.
A short road test should follow once the basics are confirmed. Pay attention to vibration, rubbing, unusual noise, or any sign that steering or suspension clearance is tighter than expected, especially if the car has changed hands recently or has aftermarket wheels that may differ from the original layout.
How often should tires on a 2024 Lexus LC500 be inspected?
Tires on a 2024 Lexus LC500 should be inspected regularly, with extra attention before longer drives or after long storage periods. Because the car uses a staggered front and rear setup, the inspection should confirm both condition and position so the 245/40R21 front and 275/35R21 rear tires remain where they belong.
A useful inspection includes looking for cracking, cuts, bulges, irregular wear, and any sign of air loss. Low-use grand touring cars can appear fine at a glance yet still develop age-related issues, so owners should treat tire condition as important even when tread depth seems acceptable.
