Can't comment on whether front or rear is appropriate, but iirc DT store did have sign regarding the rears being more appropriate.
As for DT rotations I've had many, most on tires purchased at DT but some OE that were not and never had the OP's experience. I do know that DT SOP is to take the tread depth gauge to every tire before a rotation. I try to keep up with rotations so that may explain some of the difference. Would like to know what OP's the depth difference was between the fronts and rears.
While selling tires is obviously DT's main business, as standard practice they do free rotations and plug/patch repair on all tires whether purchased at DT or not. I've not had better service anywhere and won't buy tires elsewhere.
