Temporary spare is 60 psi. Conventional spare uses the Outback cold pressures.
Keep each tire on its original side. Adjust pressures and check the wheel-nut torque afterward.
The specifications table prints Legacy on the left and Outback on the right. Legacy cold pressures are 33 psi front and 32 psi rear, on 225/55R17 and 225/50R18. They are not this page. Wheel-nut torque is on the lug nut guide. The book says rotate every 6,000 miles and keep each tire on its original side.
