70 Duster wheel and tire selection

hi, my name is rich and im doing a complete rotisserie resto on my 70 Duster. its going to paint this week, plumb crazy. anyway ive been thinking that i do not want to use the stock 14" ralleyes. im thinking that i love the body color steelies in a 15" size,sbp.i want it to look like its factory stock only with 15x7 wheels. i guess what im trying to say is can anyone reccomend a tire and wheel size that will work with no rubbing issues. my suspension is factory specs with factory disc up front. i will post pics sometime, when i figure out how. thanks
