what size tire fits them? how do most rims mount? well on adapters but is that only if they dont fit the bolt pattern? and for kos do they sit on the outside of the tire or actually in the tire so you would have to get them balanced? thanx

A tire made for 13in wheels will fit them.
They mount like any other set of 13s.
You can always buy universal bolt pattern adapters.
I don't understand your KOs question.
