Rotated car parts (5)
I believe the answer is:
tires
'rotated car parts' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for tires that I've seen before include "Weakens" , "Exhausts" , "Grows weary of rites" , "Wearies" , "Becomes weary and in need of rest" .)
