I just looked at my owner's manual ..and it doesn't show a 5 tire rotation ...just the rears directly forward to the front and the fronts crossed to the rear. This is an 02 Jeep TJ. I also consulted my 99 FSM (also for the TJ)..and it also is void of a 5 tire rotation.
I believe, IIRC, that the spare is placed on the RR and the RF (that would normally go to the RR) goes to the spare. I imagine, however, that any "interception", or detour to the spare position, in the entire process would yield the same results on average ..as long as the tires "get in line" and are all serving at all stations "in order".
