Tyre hothead shredded recently (3,5,3)
I believe the answer is:
the other day
'recently' is the definition.
(I've seen this before)
'tyre hothead shredded' is the wordplay.
'shredded' indicates anagramming the letters.
'tyre'+'hothead'='tyrehothead'
'tyrehothead' is an anagram of 'THE OTHER DAY'.
(Other definitions for the other day that I've seen before include "Not long ago" , "Quite recently" .)
