The answer is to swap the tyres front to back when the rear one begins to show signs of wear.
Only if you want to crash. A failure of a rear tire is rarely catastrophic; failure of a front one can easily be. Putting a worn tire on the front, for no good reason, is silly. when you replace a worn out rear tire, put the tire that was previously on the front on the rear, and the new one in front.
