Wheel Backspacing and tire questions

[GaryBe]

Good day All. I'm planning on replacing my Dayton Wires & tires with a "mag" style(5-spoke) wheel and a little wider tire, both, front and rear or my 83. After doing some research on here and asking some folks, I'd like get some verification that what I want to do is Viable.

Currently, I'm running the Factory Dayton Wires with a 235/78R15 tire. I want to switch those out with REV Wheels 100 Classic Series - 15x7 - 4 - 5x4.5 with BFG TA's 205/60R15(Front) and 235/70R15(Rear). I've read and heard that it should be a 15 x 6, but I see that quite a few are running 15 x 7's. I'm most concerned about the Fronts because of the possibility of rubbing when turning.

Will a 15X7 cause rubbing issues? What backspacing would be recommended? I've read 3 7/8". Any and all comments & advise are welcome.

BTW, the Dayton's will be for sale after I change over. 

Thank you

On my 82 model, I ran American Racing Mono Cast 15 x 7 wheels with zero offset and 235/70R15 tires and didn't have any problem.  zero offset on the 7" wheel is 3.5" backspace.
