The 2017 Lexus RC350 sits in the modern sport coupe space, blending sharp styling with the refined road manners expected from Lexus. Buyers looking at this exact car are usually balancing appearance, grip, ride quality, and correct fitment for either an 18-inch setup or a staggered 19-inch setup. Tire selection on the 2017 Lexus RC350 is entirely radial, with 235/45R18, 235/40R19, and 265/35R19 all appearing depending on drivetrain and front-to-rear configuration. Available choices lean toward performance-oriented blackwall tires from BFGoodrich and Nitto across several g-Force and NT555 series options. The key is confirming the exact sub-model and wheel setup before choosing a tire.
Which Tire Size Is Right for The 2017 Lexus RC350
The 2017 Lexus RC350 uses three primary tire sizes, and the right one depends on the exact drivetrain and wheel setup. Some versions use a single 18-inch radial size, while others use a 19-inch setup with either one size at all four corners or a staggered front-and-rear combination. Before choosing a tire, confirm whether the car is AWD or RWD and whether it is running 18-inch wheels or 19-inch front and rear sizes.
Fit(s): (AWD), (RWD) Front, F Sport (AWD), and F Sport (RWD) Front
Construction: Radial|Rim: 19 in
A 235/40R19 tire is a metric radial size with a 235-millimeter section width, a 40-series aspect ratio, and fitment on a 19-inch rim. On the 2017 Lexus RC350, this size appears on certain 19-inch applications, including front positions on staggered RWD setups and some AWD and F Sport configurations. Available choices include BFGoodrich blackwall radial tires in the g-Force Phenom T/A series. This size is the one to evaluate when the car uses 19-inch wheels and a performance-oriented front fitment rather than the 18-inch package.
A 235/45R18 tire uses the same 235-millimeter nominal width but adds a taller 45-series sidewall and mounts on an 18-inch rim. This radial size is used on 2017 Lexus RC350 applications with the 18-inch wheel setup, including the RWD model and an AWD configuration. BFGoodrich offers this size in blackwall form across the g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A series. It is the size to focus on when the car retains its 18-inch wheel diameter and does not use the staggered 19-inch arrangement.
A 265/35R19 tire is a wider metric radial size, with a 265-millimeter section width, a 35-series aspect ratio, and a 19-inch rim diameter. On the 2017 Lexus RC350, this size is used at the rear on staggered RWD and F Sport RWD applications, where it works as part of a front-to-rear 19-inch combination rather than a square setup. Available blackwall choices include BFGoodrich g-Force Sport Comp 2, BFGoodrich g-Force Phenom T/A, and the Nitto NT555 G2. This is the rear size to verify when the coupe uses wider back tires than front tires.
Sub-model fitment on the 2017 Lexus RC350 is not one-size-fits-all, because tire choice changes with drivetrain and, in some cases, front-versus-rear position. Checking the exact sub-model matters here, especially when comparing the 18-inch setup to the 19-inch staggered arrangements used on certain RWD and F Sport versions.

2017 Lexus RC350 (AWD)
The 2017 Lexus RC350 AWD appears with both 235/40R19 and 235/45R18 radial fitments, so wheel diameter needs to be confirmed before selecting a tire. Once that is settled, the decision shifts to comparing the available blackwall performance tires within the matching size.
The 2017 Lexus RC350 RWD uses the 235/45R18 radial size in its 18-inch configuration. Tire selection here is fairly straightforward, with the main comparison points being tire series, rim-width compatibility, and the type of road use the car sees.
The front position on the 2017 Lexus RC350 RWD staggered setup uses 235/40R19. That makes front tire selection part of a matched 19-inch front-and-rear package, so it is worth confirming the car is still using the intended staggered wheel arrangement before replacing tires.
The rear position on the 2017 Lexus RC350 RWD staggered setup uses the wider 265/35R19 radial size. Rear tire choice should be made with the front size and wheel setup in mind so the staggered layout remains consistent.
The 2017 Lexus RC350 F Sport AWD uses 235/40R19 radial tires. The practical decision is less about finding the correct size and more about choosing the right blackwall performance tire within that 19-inch fitment.
The front tire size for the 2017 Lexus RC350 F Sport RWD is 235/40R19. Tire selection should keep the staggered setup in view, especially if the car has seen wheel changes or prior tire substitutions.
The rear tire size for the 2017 Lexus RC350 F Sport RWD is 265/35R19. Choosing this size correctly means preserving the intended wider rear fitment and checking that the installed rear wheels still match the tire's requirements.
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 2017 Lexus RC350 Tires for Sale

Owners of a 2017 Lexus RC350 usually need to sort out exact tire size, wheel diameter, and whether the car uses a square or staggered setup. These FAQs focus on fitment, product selection, and the checks worth making before road use.
Tire Size & Fitment
What tire size fits a 2017 Lexus RC350?
The 2017 Lexus RC350 uses 235/45R18, 235/40R19, and 265/35R19 depending on drivetrain and wheel configuration. The 18-inch setup uses 235/45R18, while certain 19-inch applications use 235/40R19, and staggered RWD arrangements pair 235/40R19 in front with 265/35R19 in the rear.
The important next step is identifying whether the car is AWD or RWD and confirming the wheel diameter actually on the vehicle. On RWD and F Sport RWD cars, front and rear sizes may differ, so the tire choice should match the position on the car rather than assuming all four corners use the same size.
What size rim does a 2017 Lexus RC350 use?
A 2017 Lexus RC350 uses either 18-inch or 19-inch rims, depending on the specific setup. The 235/45R18 tire fits an 18-inch rim, while both 235/40R19 and 265/35R19 fit 19-inch rims.
Wheel diameter should be checked before anything else because the RC350 does not rely on one universal rim size across all versions. It also helps to confirm whether the car still has its original wheel package, since an 18-inch square setup and a 19-inch staggered setup lead to different tire choices and different front-to-rear replacement needs.
Why does the 2017 Lexus RC350 have more than one tire size?
The 2017 Lexus RC350 has more than one tire size because fitment changes by drivetrain and wheel package. Some versions use a single 235/45R18 size, while others use 19-inch tires, including staggered applications with 235/40R19 in front and 265/35R19 in the rear.
That means the right tire is tied to the exact configuration rather than just the model name on the decklid. A quick check of the sub-model, wheel diameter, and whether the car uses the same size at all four corners will prevent ordering an 18-inch tire for a 19-inch wheel or mixing front and rear sizes on a staggered car.
Choosing the Right Tire
What should I consider when choosing a 2017 Lexus RC350 tire?
Start with the exact tire size and wheel diameter used on the car, because the 2017 Lexus RC350 can be fitted with 235/45R18, 235/40R19, or 265/35R19. All of the primary fitments here are radial, so the real choice is usually between tire series, wheel compatibility, and whether the car uses a square or staggered setup.
After size is confirmed, compare practical details such as rim-width range, load figures where they are stated, and how the tire will be used. A daily-driven coupe, a weekend car, and a performance-focused setup may all lead you toward different product series even when the size itself is already settled.
What brands offer tires for the 2017 Lexus RC350?
Tires for the 2017 Lexus RC350 are available from BFGoodrich and Nitto in the sizes covered here. BFGoodrich appears across all three primary sizes, while Nitto is present in the 265/35R19 rear fitment through the NT555 G2 series.
Brand is only one part of the decision, since availability varies by tire size and by front or rear position on staggered applications. It helps to narrow the search by the exact size first, then compare the series offered in that size along with sidewall style, rim-width suitability, and the intended use of the car.
What tire series are available for the 2017 Lexus RC350?
The 2017 Lexus RC350 is covered here by BFGoodrich g-Force Comp 2 AS, BFGoodrich g-Force Sport Comp 2, BFGoodrich g-Force Phenom T/A, and Nitto NT555 G2 tire series. The exact series available depends on the tire size, with the broadest selection appearing in 235/45R18 and 265/35R19.
Series differences are useful because they help separate one tire's character from another without changing the required size. Once the right fitment is confirmed, compare which series are offered in that specific size and whether the car needs a single-size 18-inch setup or a matched 19-inch staggered front-and-rear combination.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2017 Lexus RC350?
Yes, modifications can affect tire fitment on a 2017 Lexus RC350 even when the nominal tire size looks correct. Aftermarket wheels, changes in wheel width, altered offset, suspension lowering, or body modifications can all change how a 235/45R18, 235/40R19, or 265/35R19 tire sits in the wheelwell.
A modified RC350 should be checked for wheel diameter, wheel width, and clearance at full steering lock and suspension travel before replacement tires are chosen. That is especially important on staggered 19-inch cars, where front and rear tires already differ and even small setup changes can affect rubbing, stance, or overall fit.
What should I inspect before driving a 2017 Lexus RC350 on new tires?
Before driving a 2017 Lexus RC350 on new tires, inspect the wheel size, confirm that the front and rear positions have the correct tire sizes, and check tire pressure. It is also smart to look over the wheels for damage and make sure the tires were mounted in the proper sizes for the actual configuration on the car.
A short visual check can prevent avoidable problems. Look for uneven clearances, confirm there is no contact with suspension or fender edges, and recheck pressure after the first drives. On cars with a staggered setup, make sure the wider 265/35R19 tires remain on the rear and are not mixed into the front position.
What should I check before a longer drive in a 2017 Lexus RC350?
Before a longer drive, a 2017 Lexus RC350 should have its tire pressures checked cold, along with tread condition, visible cuts, bulges, and any signs of air loss. It is also worth confirming that the tire sizes on the car still match the intended setup, particularly if the RC350 uses the 19-inch staggered front-and-rear arrangement.
Longer trips put more heat and distance into the tires, so consistency matters. Take a moment to inspect the spare plan if applicable, look for unusual wear that may suggest alignment or suspension issues, and verify that wheel hardware is secure. Those basic checks are especially useful on a coupe that may alternate between regular driving and lower-mileage use.
