Turner in emergency resort to withdraw from hearing (5,4)
I believe the answer is:
spare tyre
'turner in emergency' is the definition.
The definition suggests a singular noun which matches the answer.
'resort to withdraw from hearing' is the wordplay.
I cannot really see how this works, but
'resort' could be 'spa' (spa is a kind of resort) and 'spa' is present in the answer.
'from' could be 'e' (I've seen this in other clues) and 'e' is present in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for spare tyre that I've seen before include "what motorist carries" , "sign of over-indulgence?" , "Gastric band" , "Extra bit of fat" , "Something kept for the flat" .)
