2006 Toyota Prius: What is the tire size and pressure, and wheel size?

The tire size for the 2006 Toyota Prius is P175/65R15. The recommended tire pressure for both the front and the rear tire iS33 to 35 psi. The standard wheel size is 15" silver aluminum wheels.Your tire air pressure should be checked once a month using the same tire gauge. Low tire pressure can be dangerous and could cause a blowout. Low pressure could result from a leak or simply from the tendency of a tire to lose pressure over time. When air pressure gets too low, the tire's sidewalls flex more, and heat builds up within the tire. Excessive air pressure can also distort the shape of the tire, leading to decreased traction and increased wear and tear down the center of the tire.
