I took these pic.s last yr. This is one way to do it. Spares have useable glue on them so you can ride them without losing your mind. This requires you to periodically unroll the tyre and check the glue. Depending on conditions you might only have to freshen up the glue twice a yr. Also, use a good toe strap. Press the folded tyre flat and compress...repeat...you'll "convince" a new spare to assume a nice shape after a couple tries ;) Enjoy.
