Original model of cheap tyre burst (9)
I believe the answer is:
archetype
'original model' is the definition.
(I've seen this in another clue)
'cheap tyre burst' is the wordplay.
'burst' indicates anagramming the letters.
'cheap'+'tyre'='cheaptyre'
'cheaptyre' is an anagram of 'ARCHETYPE'.
'of' acts as a link.
(Other definitions for archetype that I've seen before include "Original model from which others are copied" , "exemplary item)" , "Very typical example" , "Very characteristic example" , "They caper about like original model" .)
