The 2024 Lexus RC300 sits in the modern luxury sport coupe space, blending sharp styling with a chassis setup that can vary meaningfully by drivetrain and F Sport configuration. That makes tire selection on this car less about a broad one-size-fits-all answer and more about matching the exact wheel and axle arrangement. The 2024 Lexus RC300 uses radial tire fitments in 18-inch and 19-inch sizes, with staggered 19-inch sizing on certain F Sport configurations. Available choices center on blackwall performance-oriented series from BFGoodrich and Nitto. For the best result, start by confirming whether the car is RWD, AWD, or an F Sport front-and-rear setup before comparing tire options.
Which Tire Size Is Right for The 2024 Lexus RC300
Three primary tire sizes apply to the 2024 Lexus RC300, and the correct one depends on sub-model, drivetrain, and whether the car uses a square or staggered setup. Two different rim diameters are involved, so the first step is confirming the exact wheel size on the car. That matters especially on F Sport versions, where front and rear fitment can differ.
Fit(s): (AWD), F Sport (AWD), F Sport (AWD) Front, and F Sport (RWD) Front
Construction: Radial|Rim: 19 in
235/40R19 is a metric radial size with a 235-millimeter section width, a 40-series profile, and a 19-inch rim diameter. On the 2024 Lexus RC300, this size is part of the 19-inch fitment used on certain AWD and F Sport front positions, giving it a clear role in more performance-focused configurations. Available choices include blackwall tires from BFGoodrich, including the g-Force Phenom T/A series. This size should be evaluated carefully against the car's exact axle position and wheel setup, especially if the RC300 has a staggered arrangement or any wheel changes from stock dimensions.
235/45R18 is a metric radial tire size that combines a 235-millimeter section width with a 45-series profile for an 18-inch wheel. On the 2024 Lexus RC300, it is the primary 18-inch fitment and appears on RWD models as well as some AWD configurations. BFGoodrich offers this size in several blackwall performance series, including g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A. This is the size to focus on when the car carries 18-inch wheels and a non-staggered setup, but wheel width and actual vehicle configuration still need to match the tire selected.
265/35R19 is a wider metric radial size with a 265-millimeter section width, a 35-series profile, and a 19-inch rim diameter. On the 2024 Lexus RC300, this size serves as the rear fitment on F Sport staggered setups, where it works with a narrower front tire rather than as a universal four-corner size. Product choices include blackwall options from BFGoodrich and Nitto across series such as g-Force Sport Comp 2, g-Force Phenom T/A, and NT555 G2. This size belongs in a rear-axle role only where the wheel width, axle position, and full front-to-rear combination all align with the car's configuration.
Fitment on the 2024 Lexus RC300 varies by drivetrain and F Sport configuration, so confirming the exact sub-model is the key first step. Some versions use a single square size, while others use 19-inch front-and-rear staggered sizing that changes tire selection by axle.

2024 Lexus RC300 (AWD)
The 2024 Lexus RC300 (AWD) can appear with either 235/40R19 or 235/45R18 radial fitment, so wheel diameter must be confirmed before choosing a tire. That makes this sub-model less about brand preference first and more about verifying the actual 18-inch or 19-inch setup already on the car.
The 2024 Lexus RC300 (RWD) uses 235/45R18 radial tires, making fitment more straightforward than the staggered F Sport arrangements. Tire selection then comes down to comparing available blackwall performance series and checking wheel width compatibility before installation.
The 2024 Lexus RC300 F Sport (AWD) uses 19-inch radial sizing and should be checked carefully for its front-and-rear arrangement. Selection is best approached by confirming axle position first, then comparing the available performance-oriented tire options within the correct size.
The front of the 2024 Lexus RC300 F Sport (AWD) uses 235/40R19 radial tires as part of a staggered 19-inch setup. That means the front tire should be chosen with the full front-and-rear combination in mind rather than treated as a standalone four-corner fitment.
The rear of the 2024 Lexus RC300 F Sport (AWD) uses 265/35R19 radial tires, pairing a wider section width with the same 19-inch wheel diameter. Tire selection should account for the staggered layout so the rear fitment complements the matching front size and wheel package.
The front of the 2024 Lexus RC300 F Sport (RWD) uses 235/40R19 radial tires. Choosing this size starts with confirming the car still carries the intended staggered setup and then comparing the available blackwall performance series for the front axle role.
The rear of the 2024 Lexus RC300 F Sport (RWD) uses 265/35R19 radial tires, completing the staggered 19-inch package. This rear size should be matched to the correct front fitment and checked against wheel width and clearance any time the car has aftermarket wheels or suspension changes.
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.

Questions about 2024 Lexus RC300 tires usually come down to identifying the correct size by drivetrain and F Sport setup, then comparing wheel diameter, staggered fitment, and available performance tire choices. The FAQs below focus on those exact decisions.
Tire Size & Fitment
What tire size fits a 2024 Lexus RC300?
The 2024 Lexus RC300 uses three primary tire sizes: 235/45R18, 235/40R19, and 265/35R19. The correct size depends on whether the car is RWD or AWD and whether it is an F Sport configuration with separate front and rear sizing.
That means the first check is not brand or tread pattern, but the exact sub-model and wheel setup on the car. An RC300 with 18-inch wheels calls for a different tire than an F Sport with a staggered 19-inch arrangement, and the rear 265/35R19 should not be treated as a universal four-corner fitment.
What size rim does a 2024 Lexus RC300 use?
The 2024 Lexus RC300 uses both 18-inch and 19-inch rim diameters, depending on configuration. The 235/45R18 size belongs to an 18-inch wheel, while 235/40R19 and 265/35R19 are both built for 19-inch wheels.
Rim diameter is the most important fitment point to confirm before comparing tire options. A 19-inch tire cannot be mounted on an 18-inch wheel, and staggered 19-inch F Sport setups still require checking front and rear wheel widths so each axle receives the proper tire size.
Do all 2024 Lexus RC300 sub-models use the same tire size?
No, 2024 Lexus RC300 sub-models do not all use the same tire size. RWD models use 235/45R18, some AWD versions use either 235/45R18 or 235/40R19, and F Sport front and rear positions can split between 235/40R19 and 265/35R19.
That variation is why the sub-model description matters before a tire is selected. A buyer looking at an RC300 F Sport needs to know whether the tire is for the front or rear axle, while an RC300 with standard 18-inch wheels follows a much simpler single-size path.
Choosing the Right Tire
What should I consider when choosing a tire for a 2024 Lexus RC300?
Start with the correct size for the car's exact configuration: 235/45R18, 235/40R19, or 265/35R19. From there, compare radial construction details such as wheel diameter, supported rim-width range where stated, load capacity when listed, and whether the tire belongs on a square or staggered setup.
The next decision is how the car is used and what kind of tire character you want within the correct size. A daily-driven RC300, a weekend coupe, and an F Sport on staggered 19-inch wheels may all point the buyer toward different series even when the dimensions themselves are correct.
What sidewall styles are available for 2024 Lexus RC300 tires?
The available 2024 Lexus RC300 tire options in these sizes use a blackwall sidewall style. That consistent appearance runs across the listed BFGoodrich and Nitto products for 18-inch and 19-inch fitments.
Since sidewall treatment is not the main differentiator here, the more useful comparison is tire series, axle position, and wheel compatibility. On this Lexus coupe, getting the right front or rear size and matching the tire to the intended wheel package matters more than sidewall appearance choice.
What brands offer tires for the 2024 Lexus RC300?
BFGoodrich and Nitto offer tires for the 2024 Lexus RC300 in the sizes used here. BFGoodrich appears across all three fitments, while Nitto is available in the 265/35R19 rear size used on staggered F Sport applications.
Brand is only one part of the selection process. It still makes sense to compare the exact tire series, confirm the proper axle location on staggered cars, and make sure the wheel diameter and width on the vehicle align with the tire being considered.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2024 Lexus RC300?
Yes, modifications can affect tire fitment on a 2024 Lexus RC300, especially on versions that already use different front and rear sizes. Aftermarket wheels, altered wheel widths, suspension changes, or ride-height changes can all influence how a 235/40R19, 235/45R18, or 265/35R19 tire sits on the car.
Any modified RC300 should be checked for wheel diameter, wheel width, and clearance at steering lock and suspension travel before a new tire is chosen. That is particularly important on F Sport cars, where the rear 265/35R19 must work within a staggered setup rather than a simple same-size arrangement.
What should I inspect before driving a 2024 Lexus RC300 on new tires?
Before driving a 2024 Lexus RC300 on new tires, inspect the wheel size, verify the tire size at each axle, and confirm inflation matches the tire and vehicle requirements. It also helps to look for any visible interference, uneven mounting, valve-stem issues, or signs that the car has mismatched front and rear tires.
A short initial road check is worthwhile after installation, especially on staggered 19-inch setups. Pay attention to steering feel, rubbing during turns, vibration, and any unusual air loss, then recheck pressure and general condition after the first few drives to make sure the setup is settling in properly.
What should I check before a longer drive in a 2024 Lexus RC300?
Before a longer drive, check that the 2024 Lexus RC300 is wearing the correct tire size at each wheel position and that pressures are set properly. The tread and sidewalls should be free of cuts, bulges, cracking, or abnormal wear, and the wheels themselves should be in sound condition.
Longer highway use puts more emphasis on stability and consistency, so it is smart to confirm that a staggered F Sport setup has not been mixed front to rear. Any RC300 that has sat for extended periods should also be inspected for age-related issues and slow air loss before being put back into regular road use.
