yepp to big in the front. And 11.5 in the back are just over kill unless your going for pure looks, cause on a rim that size the smallest tire I think you can run is a 295 or 305/30/18...and for it to look really right it would be a 315+. Which is NOT cheap AND on those tires... CHEAP and LONG lasting are 2 things that are not said in the same sentence
And unless your running 10's or better, and/or you have a serious auto-crossing machine then its wasted unless its for looks. And if THATS the case with tires that size.... you might as well put flames, stripes, N2O stickers and a big RACE ME NOW bumper sticker on your car, cuz thats what your gonna get.
Oh yeah those rims do look nice though!
