Details of the factory tire configuration
With the F Sport performance package, Lexus outfits the RC 350 with a wider rear tire to improve traction and handling balance, pairing it with a slightly narrower front tire for responsive steering and confident turn-in. The 19-inch wheel diameter is standard on this trim, enabling low-profile rubber for a firmer, more communicative ride.
Exact tire sizes can vary by market or if the vehicle is equipped with different wheel options, so always check the tire placard on the door jamb or the owner's manual for the precise specification for your car.
The following sizes apply to the factory setup when the RC 350 F Sport is equipped with the 19-inch wheels described above.
- Front tires: 235/40R19
- Rear tires: 265/35R19
Note that swapping to different wheels (for example, after-market wheels) or markets with alternative specifications may require different tire sizes. Always use the correct size to preserve handling, ABS, and traction control performance.
Additional considerations
When replacing tires, consider matching to the vehicle’s performance characteristics. If your vehicle uses run-flat tires or a different load index, verify compatibility with your specific VIN and suspension setup. For up-to-date and model-specific guidance, consulting a Lexus dealership or the owner's manual is recommended.
Summary: The 2017 RC 350 F Sport’s factory tire setup features a staggered arrangement on 19-inch wheels: 235/40R19 front and 265/35R19 rear. Always confirm the exact sizes on the vehicle’s placard and replace tires with the same or equivalent sizes and performance characteristics.
