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.

Spring Tides. When the moon is full or new, the gravitational pull of the moon and sun are combined. At these times, the high tides are very high and the low tides are very low. This is known as a spring high tide. Spring tides are especially strong tides (they do not have anything to do with the season Spring). They occur when the Earth, the Sun, and the Moon are in a line. The gravitational forces of the Moon and the Sun both contribute to the tides. Spring tides occur during the full moon and the new moon. Neap Tides. During the moon's quarter phases the sun and moon work at right angles, causing the bulges to cancel each other. The result is a smaller difference between high and low tides and is known as a neap tide. Neap tides are especially weak tides.
