What should the spare tire PSI be? I've got in on my right rear tire right now.

if it's the "donut" spare the PSI in on the sidewall of the tire. i believe it's like 50 or 60 psi. it's not the same as the psi for the normal tires on the car. i'm not sure why. i think it's due to the thin sidewalls and few steel belts in the tire. but whatever read the sidewall and get it inflated up where it says and then get a real tire on the normal rim ASAP. those skinny little things are scarry.
