There should be a label on the inside of the drivers door that will give you one option for tire pressures for factory installed tires. If you have replaced the tires and they are not exactly the same as the ones you removed the sidewall of the new tire will give you a range that is acceptable. For longer tire life try and stay within 2-3 lbs of the max pressure.
30 front 36 rear solo 30 / 40 for passengers http://www.trevdeeley.com/services/service-department/tech-tips/tire-pressures I have confirmed this with dealer
2009
32psi
Check your manual that's why you have it
Look in the owners manual.
36psi front and rear
look at the glove compartment or else 32 psi
40 front and back
for the 09 sportsyter 883 the gap is min .038 to max .043
The max tyre pressure should be on the side wall of the tyre, as all tyres are manufactured differently max pressures vary from one make to the next
Open the drivers door and you will see an information sticker on the end of the door or the latch pillar that shows the original size tires on the vehicle from the factory and the tire inflation pressure
Look on the inside of the door frame in the driver's door. There should be a sticker that indicates correct tire pressure for front and rear. This is typical on most cars and not just Subarus. Note that the correct tire pressure for a car is not necessarilythe same as the "max PSI" that the tire itself states. In fact, it usually is less.
