What is the PSI of the Toyota Mirai?
The Toyota Mirai does not have a single universal tire-pressure value (PSI). The recommended cold inflation pressure depends on the model year, wheel size, and tire type. In general, you’ll see numbers in the mid-30s psi for this vehicle, but the exact front and rear figures come from the car’s official placard and owner’s manual.
Understanding why the PSI varies on the Mirai
Because Mirai models have used different wheel sizes and tire specifications across generations, the official cold-inflation values differ. The number is chosen to balance safety, handling, fuel efficiency, and tire wear, and it can change with load and ambient temperature.
Where to find the exact PSI for your Mirai
To inflate accurately, start with the vehicle’s specified cold tire pressures for your exact configuration. The following steps show where to locate those numbers:
- Door jamb placard: The driver’s door jamb (or the edge of the door) carries the recommended cold tire pressures for front and rear tires.
- Owner’s manual: The manual includes the pressure specification for your tire size and typical loads.
- Tire size and replacement tires: If you’ve installed non-standard wheels or tires, use the tire-maker’s recommended cold PSI for that size and type.
- Temperature and heat considerations: “Cold” refers to the tires before driving; pressure will rise as tires warm up during driving.
Following these sources will yield the precise PSI values you should use for your Mirai’s tires in your local conditions and configuration.
Maintenance and safety considerations
Maintaining the recommended inflation improves safety, fuel efficiency, and tire longevity. Check tire pressure regularly, especially with seasonal temperature shifts and before long trips or when carrying heavy loads.
Summary: The Toyota Mirai’s PSI is not a single fixed value. It varies by model year and wheel/tire size, and the exact numbers are printed on the door placard and in the owner's manual. Use those sources to determine the correct cold PSI for your vehicle, typically in the mid-30s, and recheck periodically for best results.
How many PSI is a Toyota Mirai tank?
System components Hydrogen-related components The fuel cell vehicle has hydrogen tanks (10150 psi [70 MPa, 714 kgf/cm 2, 700 bar]), fuel cell stack, and hydrogen pipelines as hydrogen-related components.
What is the lawsuit against Toyota Mirai?
Toyota faces legal action over lack of hydrogen fuel infrastructure. California Mirai owners filed a class-action lawsuit against Toyota seeking $5.7 billion in damages. Plaintiffs allege Toyota concealed reliability issues and misrepresented hydrogen infrastructure.
What is the most common problem with the Toyota Mirai?
A major selling point of the Toyota Mirai is its hydrogen fuel system, which powers the car. However, several owners have reported issues with the fuel system, including leaks and poor fuel efficiency. Sometimes, the fuel cell fails to perform as expected, leading to a loss of power and driving range.
Is the Toyota Mirai being discontinued?
No, the Toyota Mirai has not been discontinued, but Toyota is streamlining its lineup by discontinuing the top-trim Limited for 2025, leaving the XLE as the only model available. The XLE trim will now include some of the features previously exclusive to the Limited model, making it a simpler and more focused offering for the year.
Key changes for 2025
- Limited trim discontinued: Toyota has eliminated the Limited trim level, focusing its efforts on the XLE.
- XLE now includes more features: The XLE will incorporate some premium features from the former Limited trim, such as a 360-degree camera, heated exterior mirrors, and front and rear parking sensors.
- Simplified lineup: The model year offers a single trim level, which may be a strategic move to reduce production costs and streamline the slow-selling hydrogen fuel-cell car.
- Higher starting price: The starting price for the 2025 Mirai XLE is higher than the 2024 model's base price, partly due to the added standard equipment.
