Lose steam (4)

I think it could be either:

flag

tire

(Other definitions for flag that I've seen before include "slow down" , "National emblem; tire" , "Give a signal" , "Iris; ensign" , "Iris - banner" .)

I've seen this clue in The New York Times, the USA Today, The Wall Street Journal, the Universal and the LA Times.
