Your probably best to just sell the 193's, with tires, they should be worth in the $1500 range for the set and buy a set of 225's - circle BMW has the set of wheels for about $2200, tires are another $1600 from them, so your looking at 3800 less 1500, so $2300 to upgrade. You can probably get the tires cheaper at tire rack or somewhere. You might just want ot watch for people selling them on places like E90post as someone is bound to get them on a car and change them out for aftermarket.
