Toyota Mirai Tyre Size Guide
Wheel Specs, PCD, Centre Bore, Torque & EV Tyres
The Toyota Mirai is a hydrogen fuel cell electric vehicle (FCEV) designed for zero-emission driving, smooth performance and advanced technology. While still rare in Australia, the Mirai represents the future of alternative fuel vehicles.
Because EV and hydrogen vehicles deliver instant torque and extra weight from battery systems, tyre selection is critical for:
-
Low rolling resistance (efficiency)
-
Noise reduction (quiet cabin)
-
Grip under instant torque
-
Long tyre life
At Autosport Tyreworld, we are building expertise in EV and hybrid tyre solutions, helping customers choose the right tyres for next-generation vehicles.
