You'll find tire-company recommendations for rotation that range from every 3,000 miles to 15,000 miles. The best interval is probably somewhere in between, at about 7,500 miles, unless the tread on one or more of your tires is wearing differently from the rest. Michelin, for instance, suggests rotating tires every 6,000 to 8,000 miles. I won't re-balance a tire unless I notice odd wear patterns or, as you mention, feel a vibration.

How frequent are tides? Coastal areas experience two low tides and two high tides every lunar day, or 24 hours and 50 minutes. The two tidal bulges caused by inertia and gravity will rotate around the Earth as the moons position changes. These bulges represent high tides while the flat sides indicate low tides. A lunar day is how long it takes for one point on the Earth to make one complete rotation and end up at the same point in relation to the moon.
