Questions
What size tires does a 2025 Lexus RC have?
The 2025 Lexus RC uses different sizes front and rear: 235/40R19 at the front and 265/35R19 at the rear.
Which size is on my 2025 Lexus RC?
Look at the sidewall of one of your tires: the size is the code that looks like 235/45R18. The label on the driver's door jamb also lists the original size and pressure for your exact trim.
What tire pressure does a 2025 Lexus RC need?
The manual gives 35 to 36 psi front, 35 to 36 psi rear depending on size, measured with the tires cold. Check it before driving, and go by the door-jamb label if it differs, because that is set for your exact car.
Can I fit a different tire size on my 2025 Lexus RC?
Stick to a factory size for your wheel unless a tire shop confirms the swap. A different overall diameter changes speedometer readings and can upset ABS and stability control, and the load index must be at least the original.
