Questions
What size tires does a 2012 Lexus RX have?
The 2012 Lexus RX came with 235/60R18 or 235/55R19 tires, depending on the trim and wheel size.
Which size is on my 2012 Lexus RX?
Look at the sidewall of one of your tires: the size is the code that looks like 235/60R18. The label on the driver's door jamb also lists the original size and pressure for your exact trim.
What tire pressure does a 2012 Lexus RX need?
The manual gives 32 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 2012 Lexus RX?
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.
