The 2021 Lexus RC F sits in the modern high-performance coupe world with a distinctly old-school streak, pairing sharp luxury-sport styling with the kind of rear-drive balance enthusiasts still seek out. That character makes tire fitment especially important, because this car uses a staggered radial setup rather than the same size at all four corners. Front fitment is 255/35R19, while the rear uses 275/35R19 on 19-inch wheels. Available choices center on blackwall performance radials from BFGoodrich and Nitto across several series. For an RC F owner, the real task is matching the correct front and rear sizes to the car's actual wheel setup and intended street use.
Which Tire Size Is Right for The 2021 Lexus RC F
The 2021 Lexus RC F uses two primary tire sizes, with 255/35R19 up front and 275/35R19 at the rear. Both are radial fitments on 19-inch wheels, so the first step is confirming position on the car rather than choosing between different wheel diameters. The real decision is selecting the right performance tire within each size and making sure the front and rear tires match the vehicle's staggered setup.
Fit(s): Base Front and Fuji Speedway Edition Front
Construction: Radial|Rim: 19 in
A 255/35R19 tire uses a 255-millimeter nominal section width, a 35-series aspect ratio, radial construction, and a 19-inch rim diameter. On the 2021 Lexus RC F, this size serves the front position in the staggered setup, so steering response, wheel-width compatibility, and maintaining the intended front-to-rear balance all matter. Available choices include BFGoodrich tires in the g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A series, all with blackwall styling. This is the size to verify when replacing front tires or confirming that the car still carries its proper 19-inch front wheel package.
A 275/35R19 tire follows the same metric radial sizing convention, with a 275-millimeter nominal section width, a 35-series profile, and a 19-inch rim diameter. On the 2021 Lexus RC F, this is the rear tire size, so it should be selected with the rear wheel width and the car's staggered fitment in mind. Options include blackwall performance radials from BFGoodrich and Nitto, with series such as g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, and NT555 G2. This is the key size to confirm when replacing rear tires or checking a car that may have had wheel changes.
Sub-model fitment is straightforward here because both the Base and Fuji Speedway Edition use the same staggered tire layout. What matters most is identifying whether you are selecting front or rear tires, since the RC F does not use the same size at both ends.

2021 Lexus RC F Base Front
The 2021 Lexus RC F Base Front uses the front half of the car's staggered radial setup, centered on a 19-inch wheel. Tire selection here is about choosing the correct front-position size and matching it to the intended handling balance and wheel width.
The 2021 Lexus RC F Base Rear uses the wider rear tire in the staggered 19-inch radial arrangement. Rear tire replacement should focus on keeping the correct rear size in place and checking compatibility with the actual rear wheel and any past modifications.
The 2021 Lexus RC F Fuji Speedway Edition Front uses the same front tire size as the standard RC F front position. That keeps selection simple, with the main choice being among available blackwall performance radial series that suit the car's use and wheel setup.
The 2021 Lexus RC F Fuji Speedway Edition Rear shares the same wider rear tire size as the standard RC F rear position. The practical step is choosing the correct rear tire in that size and confirming that the wheel package still matches the original staggered layout.
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 Size & Fitment
What tire size fits a 2021 Lexus RC F?
The 2021 Lexus RC F uses a staggered tire setup with 255/35R19 on the front and 275/35R19 on the rear. Both sizes are radial tires designed for 19-inch wheels, and that front-to-rear difference is part of the car's intended fitment rather than an interchangeable same-size arrangement.
Replacing tires on an RC F starts with confirming position on the car, since front and rear sizes are different. A car with aftermarket wheels, past tire substitutions, or suspension changes should also be checked for actual wheel width and clearance before selecting replacement tires in either size.
What size rim does a 2021 Lexus RC F use?
The 2021 Lexus RC F uses 19-inch rims with both of its primary tire sizes. The front 255/35R19 and rear 275/35R19 are both built around a 19-inch wheel diameter, so the key distinction is tire position rather than a change in rim diameter from front to rear.
Wheel diameter is only one part of the fitment picture. Front and rear wheel widths can differ on a staggered setup, and that affects which tires are suitable within each size. Checking the actual wheel dimensions on the car is especially important if it has non-original wheels or a modified suspension.
Do all 2021 Lexus RC F sub-models use the same tire size?
The covered 2021 Lexus RC F sub-models share the same staggered size layout. Both the Base and Fuji Speedway Edition use 255/35R19 at the front and 275/35R19 at the rear, so fitment remains consistent across those versions of the RC F.
That consistency makes tire selection simpler, but it does not eliminate the need to confirm front versus rear position. The RC F still depends on different tire sizes at each end, so replacement should keep the correct size on the correct wheel and account for any wheel or suspension changes made over time.
Choosing the Right Tire
What should I consider when choosing RC F tires for a 2021 Lexus RC F?
Start with the correct staggered sizes: 255/35R19 for the front and 275/35R19 for the rear. From there, compare tire series, radial construction details, rim-width compatibility, load specification where stated, and how the tire will be used, whether that means regular street driving, seasonal use, or a more performance-focused setup.
The best comparison is not just size alone, but how each product fits the car's actual wheels and intended use. Matching front and rear tires within a consistent product family is often worth considering, and a modified RC F should always be checked for wheel width, clearance, and overall tire proportion first.
What sidewall styles are available for 2021 Lexus RC F tires?
The available tires for the 2021 Lexus RC F use blackwall sidewalls. That gives the RC F a clean modern performance appearance and keeps the visual focus on wheel design and the car's aggressive stance rather than on whitewalls, raised letters, or other period-style sidewall treatments.
Since the sidewall presentation stays consistent, the bigger visual and functional differences come from tire series and brand choice within the correct front and rear sizes. Owners looking for a unified appearance should still confirm that both axle positions are being replaced with compatible tires in the proper staggered sizes.
What brands offer tires for the 2021 Lexus RC F?
BFGoodrich and Nitto both offer tires for the 2021 Lexus RC F in the applicable sizes. BFGoodrich appears in multiple g-Force series for the front and rear fitments, while Nitto is represented in the 275/35R19 rear size through the NT555 G2.
Brand choice should be considered alongside size, wheel compatibility, and the character of the tire series rather than as a standalone decision. Some RC F owners will want to keep the same brand and series family front to rear, while others may first need to verify what is currently on the car.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2021 Lexus RC F?
Yes. A 2021 Lexus RC F with aftermarket wheels, suspension changes, or altered ride height can have different tire-clearance and wheel-compatibility requirements than a stock car. Even when using the original 255/35R19 front and 275/35R19 rear sizes, wheel width and overall positioning still influence fitment.
Checking the actual setup matters before replacement, especially on a staggered performance coupe. Look at front steering clearance, rear inner and outer clearance, and whether the wheels still match the intended 19-inch tire sizes. Any rubbing, unusual wear, or mismatched sizing should be resolved before selecting new tires.
What should I inspect before driving a 2021 Lexus RC F on new tires?
Before road use, inspect wheel condition, confirm the correct front and rear tire positions, and make sure the tires are inflated properly for the vehicle's setup. It is also smart to look over the suspension and alignment condition, since a high-performance coupe can quickly show wear problems if something is out of spec.
A short check drive should include attention to vibration, pull, rubbing, and steering feel. Uneven ride height, damaged wheels, or previous curb impact can affect how new tires behave. On a staggered car like the RC F, confirming that each axle received the proper size is one of the most important final checks.
How often should tires on a 2021 Lexus RC F be inspected?
Tires on a 2021 Lexus RC F should be inspected regularly for tread wear, air loss, cuts, bulges, and sidewall damage. Frequent checks are especially useful on a performance car with low-profile tires, since road impacts and alignment changes can affect condition faster than many owners expect.
A practical routine is to look over the tires during pressure checks and before longer drives. Extra attention is worthwhile if the car sees spirited use, sits for stretches, or has aftermarket wheels. Uneven wear across the front or rear axle can also signal alignment or suspension issues that deserve correction.
