The recommended tire pressure for the stock 17 wheels on a 2010 Subaru Impreza iS33 psi in the front and 32 psi in the rear. The tires that come on an Impreza from the dealer are size 205/50R17. It is more important than You may realize to keep Your tires at the proper psi. Several of the negative side effects that You may experience when driving with improperly inflated tires are uneven wear of the tire, which can cause poor traction, plus You may find that Your vehicle's fuel economy has noticeably dropped. It can also cause weak spots in the tire walls which can lead to a blowout. The proper tire pressure is not what is listed on the side of the tire, this number is actually the max psi that it should ever be inflated too. The correct psi is the number stated by the sticker located in the glove box or on the driver door jam.
