get 18s, 17s look too small on a 4th gen accord. Here look, http://angelfire.com/ok5/pic1 , on there are my old american eagle 147 17s, i sold them fast, now i just bought some giovanna mito chrome 18s and soon i will found out how they rub. But go with 18s no matter what, a good 18 x 7.5 with about a 42 offset or 45. and about the question of whats too high, well i have never seen anything over 47.
