17" ADRs w/ kumho ecsta 712s

i just got these today from whalentire.com less than 900, shipped, mounted, balanced, valve stems, tuner lugs & lug locks. they look pimp as hell. i’ll get picks up after this weekend when i install my tokico illuminas and 1.8" drop H&Rs.

anybody know how long i’m supposed to break in those tires?
