Questions
What size tires does a 2018 Lexus LC have?
The 2018 Lexus LC uses different sizes front and rear: 245/45R20 or 245/40R21 at the front and 275/40R20 or 275/35R21 at the rear.
Which size is on my 2018 Lexus LC?
Look at the sidewall of one of your tires: the size is the code that looks like 245/45R20. The label on the driver's door jamb also lists the original size and pressure for your exact trim.
What tire pressure does a 2018 Lexus LC need?
The manual gives 33 psi, 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 2018 Lexus LC?
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.
