Questions
What size tires does a 2015 Lexus GS have?
The 2015 Lexus GS came with 225/50R17, 235/45R18, 235/40R19 or 265/35R19 tires, depending on the trim and wheel size.
Which size is on my 2015 Lexus GS?
Look at the sidewall of one of your tires: the size is the code that looks like 225/50R17. The label on the driver's door jamb also lists the original size and pressure for your exact trim.
What tire pressure does a 2015 Lexus GS need?
The manual gives 33 to 35 psi front, 33 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 2015 Lexus GS?
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.
