Tires; standards (5)
I believe the answer is:
flags
I believe this is a double definition.
'tires' is the first definition.
(I've seen this in another clue)
'standards' is the second definition.
(I've seen this before)
(Other definitions for flags that I've seen before include "Droops" , "Grows languid" , "Declines" , "Tires; national symbols" , "Banners" .)
