2013 Subaru Impreza: What is the tire size and pressure, and wheel size?

The recommended tire pressure for the 2013 Subaru Impreza iS33 psi. The tire size is 235/45r17. The standard wheel size is 17" 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. Depending on the circumstances, repeatedly overinflated tires could wear out more quickly.
