Once Upon a Tire (むかしむかしあるタイヤに lit. Long Long Ago Some Tire in Japanese) is a fairy tale-themed race track that goes through a castle. It is the fourth race course in Crash Tag Team Racing and the first one in Happily Ever Faster.
- The track's name is a pun on the popular fairy tale phrase, "once upon a time".
- The wedding coronation in the middle of the track can be turned into a shortcut: by going into a castle, overlooking the track and pulling on the lever, the figurines will open a path through the coronation diorama and into the tunnel section.
- The princess prop wears a blue dress in this race track.
