I would ride it until it shows cords. Then move the front tire to the rear and put a new one on
the front.

There are exceptions to that advice and I experienced that often in earlier times. If you are on a
tour, putting much daily distance, tires can wear out rapidly, so the relatively new but more worn
rear tire is not a dangerous old tire, as is implied in Sheldon's advice. In contrast, if tires are
not rotated (between front and rear) the front tire will eventually become an unsafe old weather
worn tire... the more dangerous one.
Before Avocet (and IRC) introduced the carbon black tread compound with Avocet slicks, we rode
primarily on Specialized Touring II tires that wore out in the Alps in about 1500 miles. I regularly
rotated tires on these tours just to make it back to the start without going through the cords.
Today, I routinely put the new tire on the front when the rear tire begins to show cords and move
the old front tire to the rear so that it doesn't die of old age on the front wheel. I don't need to
rotate tires anymore because the ones I use last a whole tour of the Alps without changing.
