What tire pressure is recommended?

You should keep your front tires 2 PSI higher than the rear, that's required for handling purposes.  The manual recommends 35/33. If you check your pressure every day, 35/33 will work fine if you don't live in extreme climates (Seattle, Vancouver, San Francisco are examples of non-extreme climates--Texas, Minnesota, Wyoming are examples of extreme climates). However, leaving it set at the factory recommended settings will result in lower mileage than higher pressures. Try 40/38 (front/rear), or even 42/40. Your rolling resistance will decrease, and your MPG will improve. The additional 5 or 7 psi also lets you be a bit lazy about the pressure checking. Extreme climates want additional pressure to deal with the extremes.  2004 Prius OEM Goodyears are rated for 44psi max cold, so don't be afraid to run them 42/40.


How do I rotate the tires?

On the 2001 Prius

On 2002-2004 Prius

Once you have swapped the tires, make sure the tire pressures are correct (raise front, lower rear).


Does the tire compartment fit a full-size spare?

No, just a thinner temporary "donut" spare.  It is full diameter, but thinner to take up less trunk space.


What are the alignment specs for a 2004 Prius?

See this page for full alignment specs and the alignment procedure from the Repair Manual.
