wheel and tires sizes that work (18")

if i go with a 18'' rim what tires will work best???? and what is the widest that will fit.?

that link didnt really help at all.
i took some measurements my self.
15" rims: 225 50 r15
16" rims: 225 45 r16
17" rims: 225 40 r17
18" rims: 225 35 r18

- just get some h&r 25mm spacers for the back and call it a day.
hope this helps anyone else that needs help with this.
