Tyre rotation - four or five tyres and rotation pattern?

[AlHeart]

I bought four new tyres last year and had to use to the spare wheel because one of the wheels was bent. I recently bought a new wheel to replace the damaged one. I may buy a fifth tyre soon so that I can have a spare tyre.

Should I incorporate the fifth one in the rotation? If so, how would that work? I have directional tyres so they would always stay on the same side of the vehicle and the tyres from the other side of the the vehicle will would always be on the be road. If this is the case, the side without the the spare would wear faster and the side with the spare would wear slower.

The only way I can see to ensure the tyres wear the most evenly is the spare gets dismounted and remounted the other way around and then installed on the other side of the vehicle. Is this done by anyone? Are there other ways to do this?
