I agree about the rotation pattern directed in our owners manual not making any sense. Until 1200 miles ago (2 rotations) I noticed my RF and RR tires wearing more than the LF and LR. I did not have the same type of tire as a spare but was same diameter so I was using the front to back same side rotation every 6000 miles. My notes in my log book at 1200 miles previous said "at the next rotation, move both right side tires to left side and left to right. ck tread measurements. For some reason the right side tires were wearing more by almost 2/32 across the tread face measured in three places left, center and right. I did the swap last year and have another 1500 miles before the next rotation.
If I were running 5 tires in my rotation for this 200, I would do like the Owners Manual says because I noticed my tires wearing in a way that I was surprised to see and adding the spare into the rotation would even that out.
I have 31,488 miles on these KO2's installed 3 years + 1 month. 15/32 tread depth at start.
Last checked avg depth, and this is after the side to side rotation.
LF 9/32, RF 10/32
LR 9/32, RR 11/32
