i know that any company that makes a billit rim can narrowthe rim to a 7" but they'll charge you about and 300 each.
225/30/20 =25.3" will go well on a 7" rim
it'll be pretty streched out on an 8.5 but wil work.
225/35/20 =26.2"will also do well on a 7" and will also be stretched on and 8.5
there are also 245/30/20 and 255/30/20
245/35/20 and 255/35/20.
