Read about tyre that's, for the most part, recycled (7)
I believe the answer is:
retread
'read about tyre' is the definition.
'retread' can be an answer for 'tyre' (retread is a kind of tyre). I am unsure of the 'read about' bit.
'for the most part recycled' is the wordplay.
I cannot really understand how this works, but
'the' could be 't' (the is pronounced as a 't' sound in some dialects) and 't' is located in the answer.
'part' could be 're' (re is a kind of part) and 're' is located in the answer.
The remaining letters 'read' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
'that's' is the link.
Can you help me to learn more?
(Other definitions for retread that I've seen before include "One much improved in rubber" , "New surface" , "Revamped Michelin" , "tyre that was worn" , "Remould" .)
