The ideal tyre pressure for a Toyota Prius varies slightly depending on the model year and tyre size, but it is generally around:

Front tyres: 35–36 PSI
Rear tyres: 33–35 PSI

For the most accurate value, check the drivers side door jamb sticker o r the owner’s manual.
How Often to Check Tyre Pressure

It is best to check tyre pressure at least once a month and before long trips. Tyre pressure can decrease due to temperature changes, so it’s especially important to check in cold weather.
Manufacturer’s Recommended vs. Custom Settings

Many Prius owners stick to the manufacturer’s recommended pressure for optimal fuel efficiency, ride comfort, and tyre longevity. However, some drivers prefer slightly higher pressure 1–2 PSI more to improve fuel economy, though this may slightly reduce ride comfort.
Effects of Incorrect Tyre Pressure

Under-inflated tyres:
Increased rolling resistance → Lower fuel economy
Poor handling, especially in corners
Uneven tyre wear → Shorter tyre lifespan
Increased risk of blowouts

Over-inflated tyres:
Harsher ride less comfort
Reduced traction, especially in wet conditions
Uneven tyre wear excess wear in the center
