Recorded volume of car wheel with caution (9)

I believe the answer is:

audiobook

I'm a little stuck... Click here to teach me more about this clue!

'recorded volume' is the definition.
I know nothing about this answer so I cannot judge whether this works.

'car wheel with caution' is the wordplay.
'car wheel' becomes 'audio' (I can't explain this - if you can you should give a lot more credence to this answer).
'with' means one lot of letters go next to another.
'caution' becomes 'book' (a footballer receiving a yellow card gets 'booked').
'audio'+'book'='AUDIOBOOK'

'of' is the link.

Can you help me to learn more?

(Another definition for audiobook that I've seen is " work, we hear".)
