Arrested over kind of tyres (8)
I believe the answer is:
retreads
'kind of tyres' is the definition.
'arrested over' is the wordplay.
'over' indicates anagramming the letters.
'arrested' with letters rearranged gives 'RETREADS'.
(Other definitions for retreads that I've seen before include "They gain fresh employment" , "Serrated like tyres restored for use" , "Arrested over resurfaced tyres" , "Serrated like remoulded tyres" , "recovered tyres" .)
