size of rims do not not matter up to 20" all that happens is you lose side wall with each step up in size.
many of us are running 17,18,19,20,22 with kits. like azan said the larger rim u get the smaller the side wall on tire gets to keep overall radius the same. heck factory cavaliers in 2002-2004 cam with 16 in rims as a option. so stepping up to 15s or 16s will be no issue. and any tire guy will know how to size them to your car when u get tires.
