What size KDWs are you looking at? You said the "best 16in", but I don't know what that's supposed to mean.
According to their site, the 225/55-16 is 808 revs/mi, and is good to fit on a 6-8" wheel, so it'll work on your 6.5" wheels. (Assuming you have stockers, of course). 215/60 is a pretty uncommon size, so unless you go with that exact same size (which limits you to basically no performance tires at all), I think that 225/55 is about the best match you're going to find.
