Questions

What size tires does a 2026 Lexus GX have?

The 2026 Lexus GX came with 265/70R18, 265/55R20 or 265/50R22 tires, depending on the trim and wheel size.

Which size is on my 2026 Lexus GX?

Look at the sidewall of one of your tires: the size is the code that looks like 265/70R18. The label on the driver's door jamb also lists the original size and pressure for your exact trim.

What tire pressure does a 2026 Lexus GX need?

The manual gives 33 to 35 psi 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 2026 Lexus GX?

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.
