The 2024 Lexus LC500h blends grand touring luxury with hybrid performance in a way that feels distinctly modern, yet still tailored to drivers who care about proportion, balance, and road presence. Its long, low coupe shape and high-end chassis tuning make tire fitment especially important because the visual stance and driving character work together. This exact Lexus LC500h uses a staggered radial setup with 245/40R21 in front and 275/35R21 in the rear, both on 21-inch rims. That means the decision is less about choosing one universal size and more about matching the correct front and rear fitment while keeping construction, dimensions, and wheel compatibility in check.
Which Tire Size Is Right for The 2024 Lexus LC500h
The 2024 Lexus LC500h uses two primary tire sizes, both in radial construction on 21-inch rims. The first step is confirming position, since 245/40R21 is the front fitment and 275/35R21 is the rear fitment on the Base setup. Once that staggered arrangement is clear, the real comparison becomes tire dimensions, intended use, and whether the wheel setup remains true to the original front-to-rear sizing plan.
245/40R21 is a metric radial size in which 245 identifies nominal section width in millimeters, 40 is the aspect ratio, R designates radial construction, and 21 is the rim diameter in inches. On the 2024 Lexus LC500h, this size serves the front position in the staggered setup, so it plays a key role in maintaining the intended front-end fitment and overall stance. Its dimensions reflect a lower-profile modern performance-oriented format rather than a vintage sizing system. This is the size to verify when confirming front wheel compatibility, clearance, and any changes from the original wheel package.
275/35R21 is a metric radial size where 275 indicates nominal section width in millimeters, 35 is the aspect ratio, R means radial construction, and 21 identifies the wheel diameter in inches. On the 2024 Lexus LC500h, this is the rear tire size in the staggered arrangement, giving the car a wider rear fitment than the front. That distinction matters because rear tire selection should stay aligned with the car's intended front-to-rear balance rather than treated as a universal four-corner size. This is the measurement to confirm when checking rear wheel width, suspension clearance, and any aftermarket wheel changes.
Sub-model fitment is straightforward here, but front and rear positions use different tire sizes. Checking the exact position matters because the Base setup is staggered, so the front and rear tires should not be treated as interchangeable.

2024 Lexus LC500h Base Front
The 2024 Lexus LC500h Base Front uses its own dedicated front tire size in radial construction on a 21-inch rim. That makes front-position confirmation the key step before choosing replacement tires, especially if the car has seen wheel changes or other fitment-related modifications.
The 2024 Lexus LC500h Base Rear uses a different radial tire size than the front, also on a 21-inch rim. Rear tire selection should stay tied to that position-specific fitment so the staggered setup remains consistent in both appearance and compatibility.
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 shopping for 2024 Lexus LC500h tires usually need to confirm the staggered front and rear sizes first. The most useful questions center on tire size meaning, 21-inch rim fitment, selection factors, modifications, and road-use checks.
Tire Size & Fitment
What tire size fits a 2024 Lexus LC500h?
The 2024 Lexus LC500h uses a staggered tire setup rather than one size at all four corners. The front fitment is 245/40R21 and the rear fitment is 275/35R21, with both sizes built in radial construction for 21-inch rims.
That means tire selection starts with position, not just year, make, and model. A buyer should confirm whether the tire is intended for the front or rear axle, then verify that the car still has the correct wheel arrangement if aftermarket wheels, spacers, or suspension changes have been added.
What size rim does a 2024 Lexus LC500h use?
The 2024 Lexus LC500h uses 21-inch rims with both of its primary tire sizes. The front 245/40R21 and rear 275/35R21 each share the same rim diameter, even though the tire widths and aspect ratios differ between the two positions.
Rim diameter is only one part of fitment, so matching the 21-inch diameter alone is not enough. Wheel width and the actual front or rear position still need to be checked, especially on a staggered setup where using the wrong wheel or tire combination can upset clearance and intended fitment.
Do all 2024 Lexus LC500h sub-models use the same tire size?
The covered 2024 Lexus LC500h Base setup does not use one identical tire size front and rear. It uses 245/40R21 at the front and 275/35R21 at the rear, so the fitment is consistent in layout but staggered by position.
That distinction matters because a front tire should be selected as a front tire and a rear tire as a rear tire, not as a universal set of four. Anyone replacing tires one axle at a time should double-check the mounted wheel location before ordering or installation.
Choosing the Right Tire
What should I consider when choosing a 2024 Lexus LC500h tire?
Start with the correct position-specific size, since the 2024 Lexus LC500h uses 245/40R21 in front and 275/35R21 in the rear. Both are modern radial sizes on 21-inch rims, so the core decision is making sure the tire matches the correct axle and wheel setup.
After size, compare the tire's physical fit with the wheel actually on the car and consider how the car is used. A low-profile grand touring coupe can be sensitive to wheel changes, so the owner should verify front and rear wheel dimensions, clearance, and overall consistency before final selection.
How do I choose between the available 245/40R21 and 275/35R21 tires for a 2024 Lexus LC500h?
The first step is not choosing between the two sizes as alternatives, because each size serves a different position on the car. The 245/40R21 belongs at the front and the 275/35R21 belongs at the rear, so the correct comparison starts within each axle's required size.
From there, look at the actual wheel setup and whether the car remains in its original staggered arrangement. Owners replacing all four tires should make sure the front pair and rear pair stay properly matched to the car's layout rather than trying to standardize the setup without checking compatibility first.
What rim-fitment details should I compare when choosing 2024 Lexus LC500h tires?
The key rim-fitment detail is that both primary sizes mount on 21-inch wheels, but the front and rear tire sizes are different. That means diameter must match, and the wheel package still needs to suit the specific front or rear tire being installed.
Beyond diameter, a careful buyer should confirm the actual wheel width and overall setup already on the car. On a staggered performance coupe, front-to-rear differences matter, and any aftermarket wheel change should be checked for proper tire pairing, suspension clearance, and fender clearance before mounting new tires.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2024 Lexus LC500h?
Yes, modifications can affect tire fitment on a 2024 Lexus LC500h even when the tire sizes remain 245/40R21 in front and 275/35R21 in the rear. Wheel changes, altered offsets, suspension lowering, spacers, or body modifications can all change how those tires sit in the wheel openings.
A staggered 21-inch setup leaves less room for assumption than a more forgiving standard fitment. Anyone buying replacement tires for a modified car should inspect steering clearance, inner suspension clearance, and outer fender clearance at both ends before treating the original size as automatically compatible.
What should I inspect before driving a 2024 Lexus LC500h on new tires?
Before road use, inspect air pressure, bead seating, visible tread and sidewall condition, and correct mounting position for each tire. On a 2024 Lexus LC500h, it is especially important to make sure the 245/40R21 tires are on the front and the 275/35R21 tires are on the rear.
A short visual check should also include wheel condition and any sign of rubbing after installation. Once the tires are mounted, the owner should confirm there is no interference during steering or suspension movement and monitor the first few drives for vibration, air loss, or unexpected contact.
How often should tires on a 2024 Lexus LC500h be inspected?
Tires on a 2024 Lexus LC500h should be inspected regularly, not just when tread wear becomes obvious. Low-profile 21-inch tires can reveal issues through sidewall damage, uneven wear, or pressure loss before the problem becomes severe enough to affect daily drivability.
Monthly pressure and condition checks are a sensible routine, with additional inspection before longer drives or after contact with potholes or road debris. Owners should look for cuts, bulges, cracking, unusual shoulder wear, and any sign that front and rear tires are wearing differently than expected.
