Forget putting the spare into the rotation, keeps the spare looking good, and if you don't include the spare, you DO NOT have to reset the tire pressure system. If you do include the spare you need to perform the sensor relearn or else the system will continue to monitor the spare, and miss one of the ground tires (something I just proved out this week
).
For four tires, it should go as:
right rear to right front
right front to left rear
left rear to left front
left front to right rear
In other words rears go forward, fronts go to the the opposite rear.
