Toyota Mirai Spare Tire Fitment Guide
The Toyota Mirai used 5x4.5" (5x114.3 mm) and 5x120 mm bolt pattern variations from 2016 to 2026 along with tire diameters ranging from 26.3" to 29.2" tall. Using a temporary compact spare tire with a diameter close to the standard tire has many benefits, especially for modern vehicles with larger brake calipers and anti-lock brakes or traction control systems.
The tire diameter and the wheel diameter clearance have been taken into account for the specific Toyota Mirai years and options. In this case, 125/80R18 and 155/85R18 spare tire sizes are used to avoid vehicle components while closely matching the original tire size diameters. We've provided a breakdown by vehicle generation and model specifics to help you find the correct Toyota Mirai spare tire.
