Questions
What size tires does a 2026 Toyota GR Supra have?
The 2026 Toyota GR Supra uses different sizes front and rear: 255/40R18 or 255/35R19 at the front and 275/40R18 or 275/35R19 at the rear.
Which size is on my 2026 Toyota GR Supra?
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.
Can I fit a different tire size on my 2026 Toyota GR Supra?
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.
