2020 Toyota Prius Tire Pressure: 15- vs. 17-Inch Tires
2020 Toyota Prius Tire Pressure: 15- vs. 17-Inch Tires with application chart, generation boundaries, verification steps and official manufacturer lookup.
For a 2020 Prius, the factory cold-pressure rows are 36 psi front and 35 psi rear with 195/65R15 tires, or 33 psi front and 32 psi rear with 215/45R17 tires.
For a 2020 Prius, the factory cold-pressure rows are 36 psi front and 35 psi rear with 195/65R15 tires, or 33 psi front and 32 psi rear with 215/45R17 tires.
These values apply to the covered U.S.-market 2020 Prius factory tire packages. Prius Prime, Prius c, Prius v, another generation, a replacement-size tire or a vehicle with a different tire-and-loading label requires its own specification.
Set pressure before driving, when the tires are cold, and use the driver's-door tire-and-loading label as the final authority. The molded pressure on the tire sidewall is a maximum-load reference for the tire—not Toyota's normal operating target. Temperature changes can move the reading even when no puncture is present.

Toyota Prius Tire Pressure Specifications
| APPLICATION / ITEM | SPECIFICATION | NOTES |
|---|---|---|
| 195/65R15 front | 36 psi cold | 250 kPa |
| 195/65R15 rear | 35 psi cold | 240 kPa |
| 215/45R17 front | 33 psi cold | 230 kPa |

| Wheel-nut torque | 76 lb-ft | 103 N·m; separate from tire pressure |
Set pressure before driving, when the tires are cold, and use the driver's-door tire-and-loading label as the final authority. The molded pressure on the tire sidewall is a maximum-load reference for the tire—not Toyota's normal operating target. Temperature changes can move the reading even when no puncture is present.
Why the 15- and 17-inch rows differ
Toyota balances tire construction, load capacity and handling as a complete package. The lower-profile 215/45R17 tire therefore uses a different cold setting from the 195/65R15 tire; equalizing all four tires to a remembered Prius number discards that engineering distinction.
Find the size molded on the tire and confirm it against the door label before selecting the chart row. If the car has replacement wheels or a nonstandard size, ask the tire and vehicle specialists for a documented pressure rather than guessing from diameter.
Set pressure cold and interpret TPMS correctly
Pressure increases as the tire warms in use. Set the baseline before driving and do not bleed a warm tire merely because the dashboard number is above the cold label value.
TPMS is a warning system, not a substitute for monthly gauge checks. Correct all four tires, inspect any tire that repeatedly loses pressure and follow Toyota's initialization procedure after tire service when the manual requires it.

2020 Toyota Prius Tire Pressure: 15- vs. 17-Inch Tires FAQs
What is the 2020 Prius pressure with 15-inch tires?+
Use 36 psi cold at the front and 35 psi cold at the rear for the cited 195/65R15 package.
What is the 2020 Prius pressure with 17-inch tires?+
Use 33 psi cold at the front and 32 psi cold at the rear for the cited 215/45R17 package.
Should all four Prius tires use the same pressure?+
No. Both factory rows use a slightly higher front setting than rear.
Is the number on the tire sidewall the correct target?+
No. Use Toyota's tire-and-loading label; the sidewall figure is not the normal vehicle setting.
