youll have more problems fitment wise with the jics than the falkens, youll have no problem with falkens
*however* you should shoot whoever told you that thats the only size the jics come in:

im pretty damned sure thats a lot more sizes than 17x8 +38
id say 17x9 +15 all around would look great, and if youre interested in a stagger you could run the 17x10 +20 or even better the 18x9.5 +12 out back
hell you could run the 18x9.5 +12 all around and itd look awesome
