Pace rated incorrectly (5)
I believe the answer is:
tread
'pace' is the definition.
(synonyms)
'rated incorrectly' is the wordplay.
'incorrectly' indicates anagramming the letters (I've seen this in other clues).
'rated' with letters rearranged gives 'TREAD'.
(Other definitions for tread that I've seen before include "Step (heavily)" , "Staircase component" , "dance" , "Depth of grooving in a tyre" , "Gripping part of tyre" .)
