The 2025 Lexus RC350 carries the late chapter of Lexus coupe design into a market that has shifted heavily toward sedans and SUVs, giving it a more specialized appeal for drivers who still want a rear-drive-based luxury sport coupe experience. Its tire fitment reflects that mix of comfort, grip, and sharp response, with radial sizes that vary by drivetrain and F Sport configuration. Depending on the setup, the RC350 uses 235/45R18, 235/40R19, or a staggered 19-inch arrangement with 265/35R19 at the rear. That makes the real decision less about guessing a generic size and more about confirming the exact sub-model, wheel diameter, and intended balance of appearance and road use.
Which Tire Size Is Right for The 2025 Lexus RC350
The 2025 Lexus RC350 uses three primary tire sizes, and the correct one depends on the exact sub-model and wheel setup. Some versions use an 18-inch fitment, while others use 19-inch tires, including a staggered F Sport RWD arrangement with a different rear size. Before choosing a tire, confirm whether the car is RWD or AWD, whether it is an F Sport, and whether the wheels are 18- or 19-inch.
Fit(s): (AWD), F Sport (AWD), and F Sport (RWD) Front
Construction: Radial|Rim: 19 in
235/40R19 is a metric radial size with a 235-millimeter nominal section width, a 40-series aspect ratio, and fitment for a 19-inch wheel. On the 2025 Lexus RC350, this size is part of the sport-oriented 19-inch fitment used on certain AWD and F Sport configurations. Available choices center on BFGoodrich in a Blackwall presentation, including the g-Force Phenom T/A series. This size is worth evaluating when the car already has the 19-inch setup and you want to preserve the intended wheel diameter and low-profile appearance.
235/45R18 is a metric radial size that combines a 235-millimeter section width with a 45-series profile on an 18-inch rim. This is the primary fitment for the 2025 Lexus RC350 RWD and also appears on AWD versions equipped with the 18-inch wheel package. Product choices include several BFGoodrich Blackwall radials across the g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A series. It is the right size to consider when maintaining the standard 18-inch wheel fitment and comparing tires by series character and rim-width compatibility.
265/35R19 is a wider metric radial size with a 265-millimeter nominal section width, a 35-series profile, and a 19-inch rim diameter. On the 2025 Lexus RC350, this size serves the rear position of the staggered RC350 F Sport RWD setup rather than every version of the car. Choices in this size include BFGoodrich and Nitto Blackwall performance-oriented radials in multiple series. This rear fitment deserves extra attention because staggered applications require matching the tire to the correct axle position, wheel width, and existing front-to-rear setup.
Tire fitment for the 2025 Lexus RC350 is not the same across every covered sub-model. Checking the exact drivetrain and F Sport configuration matters first, because the tire size can change with both trim and wheel package, and the F Sport RWD setup also uses a dedicated rear size.

2025 Lexus RC350 (AWD)
The 2025 Lexus RC350 (AWD) uses either 235/40R19 or 235/45R18, so wheel diameter must be confirmed before selecting a tire. That makes this version less about choosing between constructions and more about matching the tire to the actual 18- or 19-inch wheel setup already on the car.
The 2025 Lexus RC350 (RWD) uses 235/45R18 as its primary tire size. Tire selection here focuses on comparing available radial choices within that size, including tire series details and the wheel-width range supported by the product.
The 2025 Lexus RC350 F Sport (AWD) uses 235/40R19. For this configuration, the decision stays within the 19-inch radial fitment and centers on selecting the tire that matches the car's wheel package and the owner's preferred balance of style and road use.
The front axle of the 2025 Lexus RC350 F Sport (RWD) uses 235/40R19. That means front tire selection should stay aligned with the staggered layout rather than treating the car as though it uses the same size at all four corners.
The rear axle of the 2025 Lexus RC350 F Sport (RWD) uses 265/35R19, a wider 19-inch radial size than the front. Rear tire choice should be made with the staggered arrangement in mind so wheel width, axle position, and overall setup remain 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.

Tire questions for the 2025 Lexus RC350 usually come down to sub-model fitment, 18- versus 19-inch wheel confirmation, staggered F Sport sizing, and how to compare the available radial tire series for the way the car is actually equipped and driven.
Tire Size & Fitment
What tire size fits a 2025 Lexus RC350?
The 2025 Lexus RC350 uses three primary tire sizes: 235/45R18, 235/40R19, and 265/35R19. The correct fitment depends on the exact version of the car, since RWD, AWD, and F Sport configurations do not all use the same wheel and tire setup.
The first step is confirming the exact sub-model and wheel diameter already on the car. A standard RC350 RWD uses 235/45R18, while some AWD and F Sport versions use 19-inch fitments, and the RC350 F Sport RWD uses a staggered arrangement with a wider rear tire.
What size rim does a 2025 Lexus RC350 use?
The 2025 Lexus RC350 uses either an 18-inch or 19-inch rim, depending on the sub-model and wheel package. The 235/45R18 size fits an 18-inch wheel, while 235/40R19 and 265/35R19 fit 19-inch wheels.
Wheel diameter should be verified before anything else because the RC350 does not use one universal rim size across every configuration. Looking at the tire sidewall or confirming the actual wheel on the vehicle helps avoid ordering an 18-inch tire for a 19-inch setup or overlooking a staggered front-to-rear arrangement.
Why does the 2025 Lexus RC350 have more than one tire size?
The 2025 Lexus RC350 has more than one tire size because fitment changes with drivetrain, wheel package, and F Sport configuration. Some versions use 18-inch wheels, some use 19-inch wheels, and the F Sport RWD setup uses a staggered combination with a wider rear tire.
That variation means tire selection starts with identifying how the car is equipped rather than choosing by model name alone. Two RC350s from the same year can need different sizes, so checking the current wheel diameter and whether the car has a square or staggered setup is the practical next step.
Choosing the Right Tire
What should I consider when choosing a 2025 Lexus RC350 tire?
Start with the exact size and wheel setup your 2025 Lexus RC350 uses. This model can require 235/45R18, 235/40R19, or 265/35R19, and the right choice depends on whether the car is RWD, AWD, or an F Sport with a staggered layout.
After confirming fitment, compare the available radial tires by series, sidewall presentation, and any stated rim-width range or load specification. That approach is especially important on the F Sport RWD, where the rear tire is different from the front and should be chosen with the axle position and wheel size in mind.
What brands offer tires for the 2025 Lexus RC350?
BFGoodrich offers tires across all three primary 2025 Lexus RC350 sizes, and Nitto is available in the 265/35R19 rear fitment used on the RC350 F Sport RWD. All of the available options for this application are radial Blackwall tires.
Brand choice matters most after the size and wheel setup are confirmed. On the 18-inch and 19-inch front fitments, selection stays within BFGoodrich series, while the wider rear 265/35R19 adds a second brand option, making it easier to compare tire series character within the correct staggered application.
What tire series are available for the 2025 Lexus RC350?
The 2025 Lexus RC350 is covered by several tire series, including BFGoodrich g-Force Comp 2 AS, BFGoodrich g-Force Sport Comp 2, BFGoodrich g-Force Phenom T/A, and Nitto NT555 G2 in the applicable rear 265/35R19 fitment. Availability varies by tire size.
Series comparison is useful when the size has already been narrowed down, especially in 235/45R18 and 265/35R19 where there is more than one product to consider. Instead of treating every RC350 tire the same, compare series within the exact size so the choice stays aligned with the vehicle's actual wheel and axle setup.
Restoration & Appearance
Does correct tire fitment matter for a 2025 Lexus RC350 restoration or appearance-focused build?
Yes. Even on a modern coupe like the 2025 Lexus RC350, correct tire fitment affects both appearance and proportion because wheel diameter, sidewall height, and overall stance are tied closely to the size the car was set up to use. The RC350 can wear either 18-inch or 19-inch tires, and some versions are staggered.
An appearance-focused build should begin by preserving the intended relationship between the wheel and tire, not by choosing a size only because it looks aggressive. Confirm whether the car uses 235/45R18, 235/40R19, or the staggered 235/40R19 front and 265/35R19 rear combination before making any style-driven change.
How does tire construction affect the appearance of a 2025 Lexus RC350?
All of the primary 2025 Lexus RC350 fitments here are radial tires, so construction choice is straightforward compared with an older collector car that might involve bias-ply decisions. Appearance differences come more from the tire's profile, width, and series styling within the correct size than from switching between construction types.
That means the visual result depends heavily on keeping the proper 18- or 19-inch fitment and, on the F Sport RWD, maintaining the staggered front and rear relationship. A low-profile 19-inch setup presents the car differently from the 18-inch arrangement, even when both remain within the correct RC350 fitment family.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2025 Lexus RC350?
Yes. Modifications can affect tire fitment on a 2025 Lexus RC350, especially because this model already uses multiple factory tire sizes and, in some versions, a staggered setup. Changes such as aftermarket wheels, different offsets, suspension lowering, or altered ride height can change clearance and wheel-width compatibility.
A modified RC350 should be checked by actual wheel diameter, width, and axle position instead of relying only on the original model name. Front steering clearance, inner-fender space, and rear clearance all matter, particularly when working with 19-inch tires or the wider 265/35R19 rear size used on the F Sport RWD.
What should I inspect before driving a 2025 Lexus RC350 on new tires?
Before driving a 2025 Lexus RC350 on new tires, inspect the wheel size, confirm the correct tire size for the sub-model, and verify that each tire is mounted in the proper position. On staggered F Sport RWD cars, that means making sure the 235/40R19 front and 265/35R19 rear placements are not mixed.
A road-use check should also include tire pressure, valve condition, tread and sidewall inspection, and a quick look for rubbing at full steering lock or under suspension compression. Any car with recently changed wheels or suspension benefits from an extra clearance check before regular driving or a longer trip.
What should I check before a longer drive in a 2025 Lexus RC350?
Before a longer drive, confirm that the 2025 Lexus RC350 is wearing the correct tire size for its exact configuration and that all four tires are in sound condition. Look for uneven wear, cuts, bulges, cracking, or slow air loss, and make sure the wheel and tire positions are correct on any staggered setup.
Longer trips also make it worth checking pressure carefully and giving extra attention to the spare plan or roadside support arrangement, since not every RC350 uses the same size front to rear. A few minutes spent verifying tire condition and fitment can prevent turning a simple tire issue into a trip-ending problem.
