Toyota Prius Tire Pressure (Recommended PSI)
TL;DR
Cold tire pressure ranges from about 32 to 39 PSI across Prius generations and trims - the base 15-inch wheel and the larger 17-inch or 19-inch wheel setups are specified differently, so always confirm against your own door placard.
Why there is no single number for the Prius
Every Toyota Prius has a tire and loading information placard on the driver-side door jamb (the edge of the body the door closes against). That sticker - not a forum post, not a general rule of thumb - is the only figure that is correct for your exact car, because Toyota sets different cold-inflation targets depending on the generation, the trim, and which wheel and tire size that trim was built with.
What credible sources confirm, by generation
The figures below come from published Toyota tire placards and placard-aggregator databases (such as tirepressure.org) cross-checked against each other. Where a generation offered more than one wheel size, the pressures differ noticeably between them, sometimes by several PSI.
| Generation / years | Trim or tire size | Front (PSI) | Rear (PSI) |
|---|---|---|---|
| 1st gen (2000-2003) | All trims, 175/65R14 | 35 | 33 |
| 2nd gen (2004-2009) | All trims, 195/55R16 | 35 | 33 |
| 3rd gen (2010-2015) | Base/One/Two/Three/Four, 195/65R15 | 35 | 33 |
| 3rd gen (2010-2015) | Five/Persona Series, 215/45R17 | 33 | 32 |
| 4th gen (2016-2022) | Two/Three/Four/Technology, 195/65R15 | 36 | 35 |
| 4th gen (2016-2022) | Two Eco, 195/65R15 | 39 | 36 |
| 4th gen (2016-2022) | Touring/Limited/XLE, 215/45R17 | 33 | 32 |
| 5th gen (2023-present) | L Eco, 195/65R15 | 39 | 36 |
| 5th gen (2023-present) | LE/XLE/Limited/Nightshade, 195/65R15 | 35-36 | 33-35 |
| 5th gen (2023-present) | XLE/Limited, P215/45R17 (optional 17-inch upgrade) | 33 | 32 |
A note on the current (5th-generation) Prius
The redesigned 2023-and-later Prius ships on a 195/65R15 tire as standard across all trims, with a P215/45R17 tire offered as an optional upgrade on the XLE and Limited trims. The base L Eco trim placard calls for a notably higher 39 PSI front and 36 PSI rear on its 195/65R15 tire - continuing the Eco-trim tuning seen on the previous generation - while the other 15-inch-wheel trims (LE, XLE, Limited, Nightshade) run 35-36 PSI front and 33-35 PSI rear, and cars fitted with the optional 17-inch tire drop to 33 PSI front and 32 PSI rear. Because the pressure depends heavily on which tire your specific car was optioned with, always confirm against your own door placard, especially if your car has the larger wheel.
Front versus rear, and seasonal changes
- On most Prius generations the front tires run 1-3 PSI higher than the rear - this is normal and intentional, matching the car's weight distribution and handling tuning.
- Cold pressure means measured before the car has been driven that day, or after sitting at least three hours; a warm reading after driving will read 2-5 PSI higher and should not be used to set pressure.
- Some placards list a separate, higher pressure for full passenger and cargo loading, and some owner's manuals list a slightly higher winter pressure - check both sections of your placard, not just the main figure.
Where to find the correct number for your car
The driver-door placard is the authoritative source. If it is missing or unreadable, the owner's manual for your exact model year and trim (available from Toyota or a dealer) restates the same figures, and the tire sidewall itself lists the maximum pressure the tire can hold (not the recommended running pressure - do not use that number to set inflation).

Frequently asked questions
Is 35 PSI correct for every Toyota Prius?
No. 35 PSI front is common on base-trim 15-inch-wheel Prius models across several generations, but Eco trims with the same wheel size call for up to 39 PSI front, and 17-inch-wheel trims (Touring, Limited, XLE, Five) typically call for only 33 PSI front. Always match the figure to your specific trim and tire size from the door placard.
Why do the front and rear tires have different pressures?
The front tires carry more of the engine, transaxle, and battery weight and do most of the steering work, so Toyota specifies a slightly higher cold pressure up front (often 1-3 PSI more) than the rear on nearly every Prius generation. This is normal and should not be evened out.
Where exactly is the tire pressure placard on a Prius?
It is a sticker on the door jamb of the driver's side - the vertical edge of the body that the driver's door closes against, visible when the door is open. It lists tire size, cold PSI for front and rear, and sometimes a separate figure for maximum load.
Does the Prius Eco trim really need higher tire pressure than other trims?
Yes, on the 4th-generation Prius (2016-2022) the Two Eco trim placard specifies 39 PSI front and 36 PSI rear, noticeably higher than the 36/35 PSI used by other 15-inch-wheel trims of the same generation - this was part of Toyota's efficiency tuning for that trim, and the placard on your specific car is the way to confirm it.
