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.

If the storm surge arrives at the same time as the high tide, the water height will be even greater. The storm tide is the combination of the storm surge and the normal astronomical tide. For example as hurricane moves ashore, a 15-foot surge added to the normal 2-foot tide creates a storm tide of 17 feet.
