Aftermarket fender flare coverage

Im getting ready to purchase a 2014/2015 double cab tacoma. Im going to put a rancho 2.5" lift with some 285 75 r16 tires on konig countersteer offroad wheels.

From what I've gathered here in the forums, the bushwacker flares only add 1/2" coverage over stock... Will that be enough to cover that wheel/tire combination? The wheels have 4.5" backspacing with 0 offset.

I've got 35 12.50s on my F150 now and I never got around to adding big enough flares to cover them. Any time I get in the mud I seem to take half of it home with me on the side of my truck... I'd rather just avoid that from the get go this time around.

Thanks for the help, I appreciate it.
