The 2024 Lexus RC350 blends modern Lexus refinement with a traditional rear-drive sport coupe shape, giving buyers a car that balances everyday comfort with a more focused grand-touring character. Tire fitment matters here because the RC350 uses more than one radial size, and the exact setup depends on drivetrain and F Sport configuration. Some versions use 235/45R18, others use 235/40R19, and the F Sport RWD setup adds a wider 265/35R19 rear tire. Available choices stay firmly in modern blackwall radial territory, with BFGoodrich and Nitto options in several g-Force and NT555 series. The right selection starts with confirming the exact sub-model, wheel diameter, and whether the car uses a square or staggered setup.
Which Tire Size Is Right for The 2024 Lexus RC350
The 2024 Lexus RC350 uses three primary tire sizes, and choosing correctly starts with identifying the exact sub-model and wheel setup. Fitment varies by drivetrain and F Sport configuration, with both 18-inch and 19-inch rim diameters in use. Some versions share a single size at all four corners, while the F Sport RWD setup uses a staggered arrangement that pairs a 235/40R19 front tire with a wider 265/35R19 rear.
Fit(s): (AWD), F Sport (AWD), and F Sport (RWD) Front
Construction: Radial|Rim: 19 in
The 235/40R19 size uses a 235-millimeter nominal section width, a 40-series aspect ratio, radial construction, and a 19-inch rim diameter. On the 2024 Lexus RC350, this size is part of the 19-inch fitment used on AWD configurations and on the front of the F Sport RWD setup, so it plays a key role in cars with a more aggressive wheel package. Available choices include BFGoodrich products in blackwall form, including the g-Force Phenom T/A series. This size should be matched carefully to the correct sub-model and axle position before comparing tires.
The 235/45R18 size combines a 235-millimeter nominal section width with a 45-series profile, radial construction, and an 18-inch rim diameter. For the 2024 Lexus RC350, it serves buyers with the 18-inch square setup used on the RWD model and on one AWD configuration, making it an important fitment for owners who want to stay with the standard-width arrangement. BFGoodrich offers several blackwall choices here, including g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A. This size is the one to evaluate when the car wears 18-inch wheels at all four corners.
The 265/35R19 size uses a wider 265-millimeter nominal section width, a 35-series aspect ratio, radial construction, and a 19-inch rim diameter. On the 2024 Lexus RC350, this is the rear tire size for the F Sport RWD staggered setup, where it works with a narrower 235/40R19 front tire rather than serving as a full four-corner fitment. Product choices include blackwall radials from BFGoodrich and Nitto, with series such as g-Force Sport Comp 2, g-Force Phenom T/A, and NT555 G2. This size matters most when preserving the intended front-to-rear tire relationship on the F Sport RWD configuration.
Sub-model fitment for the 2024 Lexus RC350 is not one-size-fits-all. Drivetrain, wheel diameter, and F Sport configuration all affect the tire setup, so confirming the exact version of the car is the first step before comparing tire options.

2024 Lexus RC350 (AWD)
The 2024 Lexus RC350 (AWD) appears with both 235/40R19 and 235/45R18 fitments, which means wheel diameter must be confirmed before choosing a tire. Once that is settled, the decision becomes selecting the right blackwall radial within the correct size.
The 2024 Lexus RC350 (RWD) uses the 235/45R18 radial size, making fitment more straightforward than the staggered F Sport arrangement. Tire selection then centers on comparing the available BFGoodrich blackwall choices within that 18-inch setup.
The 2024 Lexus RC350 F Sport (AWD) uses the 235/40R19 radial size. That keeps the focus on choosing the right 19-inch blackwall tire rather than sorting through multiple axle sizes.
The front of the 2024 Lexus RC350 F Sport (RWD) uses 235/40R19, making it one half of a staggered 19-inch package. Front-tire selection should be considered together with the wider rear size so the overall setup stays properly matched.
The rear of the 2024 Lexus RC350 F Sport (RWD) uses the wider 265/35R19 radial size. That wider rear fitment is central to the tire decision, especially when replacing tires in pairs or maintaining the intended staggered appearance and balance.
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.
Best 2024 Lexus RC350 Tires for Sale
Available 2024 Lexus RC350 tires stay in modern radial blackwall form, with BFGoodrich covering all three sizes and Nitto joining the 265/35R19 rear fitment.

2024 Lexus RC350 tire questions usually come down to exact size by sub-model, 18-inch versus 19-inch wheel fitment, staggered F Sport setup details, and how to compare the available radial tire choices before putting the car back on the road.
Tire Size & Fitment
What tire size fits a 2024 Lexus RC350?
The 2024 Lexus RC350 uses three primary tire sizes: 235/45R18, 235/40R19, and 265/35R19. The correct size depends on drivetrain and F Sport configuration, with some versions using a square setup and the F Sport RWD arrangement using a staggered front-and-rear combination.
The important next step is confirming the exact sub-model and wheel package already on the car. An 18-inch RC350 RWD setup should not be treated the same as a 19-inch F Sport package, and a staggered car needs the correct tire on each axle rather than four identical replacements.
What size rim does a 2024 Lexus RC350 use?
The 2024 Lexus RC350 uses both 18-inch and 19-inch rim diameters, depending on configuration. The 235/45R18 tire fits an 18-inch rim, while the 235/40R19 and 265/35R19 sizes fit 19-inch rims.
Checking rim diameter before ordering tires is essential because a tire designed for an 18-inch wheel cannot be mounted on a 19-inch wheel, or the other way around. On this Lexus, that check also helps separate standard square setups from the staggered F Sport RWD arrangement.
Why does the 2024 Lexus RC350 have more than one tire size?
The 2024 Lexus RC350 has more than one tire size because fitment changes with drivetrain, wheel package, and F Sport configuration. Some versions use 235/45R18, others use 235/40R19, and the RC350 F Sport RWD setup adds a 265/35R19 rear tire as part of a staggered package.
That means tire selection starts with the exact version of the car rather than the model name alone. Looking at the current wheel diameter and checking whether the car carries the same size front and rear will prevent ordering a tire that belongs to a different RC350 configuration.
Choosing the Right Tire
What should I consider when choosing a 2024 Lexus RC350 tire?
Start with the correct size for the exact 2024 Lexus RC350 configuration, then compare construction, rim-width compatibility, load figures where stated, and the intended role of the tire. Since all of the available options here are radial blackwall tires, the main differences come from size, series, and application within the RC350 lineup.
A square 235/45R18 setup calls for a different buying approach than a staggered 235/40R19 and 265/35R19 F Sport arrangement. It also helps to think about whether the car is used mainly for daily road miles, seasonal driving, or occasional enthusiast use before narrowing the choices.
What brands offer tires for the 2024 Lexus RC350?
BFGoodrich is the main brand across the 2024 Lexus RC350 size range, covering 235/40R19, 235/45R18, and 265/35R19. Nitto also appears in the 265/35R19 rear fitment, giving owners of the F Sport RWD staggered setup another brand choice for that axle size.
Brand comparison should still happen within the correct tire size and intended position on the car. A rear 265/35R19 option does not solve a front-tire replacement need, and an 18-inch RC350 should be evaluated separately from 19-inch F Sport fitments before focusing on brand preference.
What tire series are available for the 2024 Lexus RC350?
The 2024 Lexus RC350 is available with several tire series, including BFGoodrich g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, and Nitto NT555 G2. Not every series appears in every size, so the available mix changes depending on whether the car uses 18-inch or 19-inch tires.
Series selection matters because it shapes the product comparison once the correct fitment is confirmed. Owners should match the series choice to the actual wheel setup on the car first, then compare details such as rim-width range, load figures where given, and how the tire fits the car’s intended use.
Restoration & Appearance
Which tire should I choose for a period-style 2024 Lexus RC350?
A period-style approach is less about vintage appearance on a 2024 Lexus RC350 and more about staying close to the car’s original visual character. Since the available choices here are modern blackwall radials in the correct 18-inch and 19-inch sizes, the most appropriate look usually starts with keeping the factory-style size relationship intact.
That is especially important on the F Sport RWD model, where the staggered 235/40R19 front and 265/35R19 rear setup contributes to the car’s stance. Choosing the correct size and wheel diameter first will preserve the intended presentation better than forcing the same tire across every RC350 configuration.
Does correct tire fitment matter for a 2024 Lexus RC350 restoration or preservation project?
Correct tire fitment matters on a 2024 Lexus RC350 because size, wheel diameter, and front-to-rear arrangement all affect how the car sits and how complete the finished presentation feels. Even on a modern collector or preservation project, the visual result depends heavily on using the proper 18-inch or 19-inch fitment for the exact sub-model.
Owners aiming for a highly accurate presentation should verify the actual wheel package on the car before selecting tires. On F Sport RWD examples, preserving the staggered relationship is just as important as choosing the right brand or series, since the rear tire is intentionally wider than the front.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2024 Lexus RC350?
Yes, modifications can affect tire fitment on a 2024 Lexus RC350. Aftermarket wheels, changes in wheel width, suspension lowering, alignment changes, or body alterations can all change how a 235/45R18, 235/40R19, or 265/35R19 tire sits in the wheelwell and how much clearance it has while driving.
A modified RC350 should be checked for wheel diameter, wheel width, and front-to-rear sizing before replacement tires are chosen. Extra attention is worthwhile on F Sport RWD cars, since the wider 265/35R19 rear tire already depends on a staggered setup and can be affected by changes at either axle.
What should I inspect before driving a 2024 Lexus RC350 on new tires?
Before driving a 2024 Lexus RC350 on new tires, inspect tire pressure, confirm that the correct size was mounted at each position, and look over the wheels for any visible damage. It is also smart to check for proper clearance around fenders, suspension components, and steering travel, especially on 19-inch or staggered setups.
A short, careful road test can help confirm that the car tracks cleanly and that nothing rubs under normal movement. On an RC350 F Sport RWD, verifying that the 235/40R19 front and 265/35R19 rear positions were not mixed is just as important as checking inflation and wheel condition.
What should I check before a longer drive in a 2024 Lexus RC350?
Before a longer drive in a 2024 Lexus RC350, check inflation, tread condition, sidewall condition, and any signs of uneven wear or slow air loss. It also helps to verify that the car is wearing the proper tire size for its exact configuration, particularly if it uses 19-inch wheels or a staggered F Sport arrangement.
Longer trips put more emphasis on consistency across the whole set, so wheel condition and recent service work are worth reviewing as well. A quick look at axle position matters too, because the wider 265/35R19 rear fitment on an F Sport RWD should remain on the rear rather than being rotated forward.
