Just to clarify a little the Tacoma Trd pro wheels are 16" and will not fit a 5th gen. The look to have different backspacing too, the spokes look more recessed than the 17". Personally I like the look of the 16" better or the newer 4Runner trd wheel, just me though.
I can only guess that they ordered you the 17" and yes they do not look very complimentary with stock rubber, in fact kinda fugly. They are a couple of members that have this wheel and real rubber combo on the forum, sorry I can't recall their usernames.
