When we describe something as 'tilted' we usually mean 'inclined at an angle' and it could be said to be at 'full tilt' when it was about to topple over. The expression 'full tilt' is most often heard these days in regard to the Full Tilt poker game. Of course, that isn't the origin of the term, although the source is related to another type of poker - the lance used in medieval jousting.
Tilt derives from the Old English word tealt or tylte, meaning to totter unsteadily. It isn't surprising that tilting was the early name for jousting, as the sport involves two knights on horseback charging at each other and trying to topple their opponent off his horse. This is the same meaning of tilt as in the eponymous hero's 'tilting at windmills' in Cervantes' Don Quixote.
The earliest references to 'the joust' (or 'just') come from the 13th century and the alternative name 'the tilt' three centuries later. Henry Ellis edited a 19th century work called Original Letters Illustrative of English History. In that he printed a letter, dated 1511, which includes this text:
"Knightes shall present themself... in harneys for the Tylte."
The History of Tom Thumb, dated around 1600, contains the earliest reference to 'full tilt':
"The cook was running on full tilt, When Tom fell from the air."
