Everybody is sort of correct here in my opinion , that whatever their choice has been working stick with it.Can't go wrong for example , to go with owner's manual -IF you've got it (Google it ?).And of course directionals gotta stay on same side - and if rear's are wider an expensive option some try is "busting them off" for a remount by crossing the sides over.Good tires and a decent suspension coupled with that 5k - 8k interval will virtually never have problems -unless a "Fluke" ie. physical damage via mfr. defect or road/mounting damage.
Here's the important tip I can give though - as soon as there is any pull , unevenness , anything strange about your tires after several thousand miles or RIGHT after you've done your typical rotation , do this - "X-cross" them by front crossed to rear , and rear crossed to front . For I've "corrected" and/or "nipped in the bud" on several instances situations that frequently in the past have gone bad to worse very quickly. Basically you're able to run out and get more maximum mileage out of them instead of having to discard , or even worse suspecting suspension parts and doing unnecessary and expensive "shotgun approach" when it's the tires taking what can be called an "uneven set" whearas my aforementioned rotation is THE next thing to try .Of course all (symmetrical,asymetrical/side-out) except directional are candidates ; one more note is the directional tires I've had do not seem to be as susceptible to weird wear - only a guess that mfr's give more reinforcement , better Q/C etc. and they are usuallythe higher speed ratings which are "stiffer" bodied , that keeps shape over their duration much better.
