Will a 215/60r15 tire with a 15x7 wheel fit?

No idea. But you will be very limited. You'll be lucky to get a 205 tire on it without rubbing on the fender.

By the way, the link takes me to an 18x8 wheel with 4.5" backspacing.
Ok wrong link I guess. Would a 15x8 all around with a 4.50" back spacing work better?
