Keep the rears wearing the same... cross front L-to-R, and replace in sets of two or four... unless they rot from age/UV destruction beforehand.

You’re not going to have much discrepancy in tire diameter, rotating them on a set schedule. That’s the whole point of rotating them around; keep consistent wear, without an abnormal pattern forming in the tread.
On an E-Series chassis, it’s absolutely critical to rotate, given the constant camber and toe changes of the TTB frontend. Only swapping them side-to-side, guarantees a chewed up set of front tires.
