'car part which had been inflated' is the definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Maybe there's a link between them I don't understand?

'i cut repayment arranged' is the wordplay.
'arranged' indicates an anagram (letters rearranged).
'i'+'cut'+'repayment'='icutrepayment'
'icutrepayment' with letters rearranged gives 'PNEUMATIC TYRE'.

'for' is the link.

Can you help me to learn more?
