Tire feature (5)
I believe the answer is:
tread
'tire feature' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for tread that I've seen before include "Depth of grooving in a tyre" , "Surface of car tyre" , "Walk or step like pattern on tyre" , "A measurement of tyre" , "Put one's foot down!" .)
