not quite...

off set can be positive or negative. measure from the centreline of the wheel.
ie. most FWD car wheels are negative offset, while deep dish wheels for RWD cars can be positive offset.

Backspacing is total distance from the hub face of the wheel to the lip of the wheel (ie. if you put a straight edge spanning accross the back of the wheel)

If that's the case than a 245/45/17 would be fine as long as you're planning to run a wider wheel to match it. I wouldn't suggest anything narrower than a 8" wheel
i agree a 8" wide wheel is needed.
245/45R17 might be too tall. maybe consider a 40 series. confirm with a online tire size calculator (google it).

Also, the wheel offset is going to need to be perfect, so you dont rub too bad
