The wheels and tires will fit under a 97. However, in order to do so, you will need at least 7 3/8'' of backspacing. Any less than that and your tire (315=12 1/2'' wide) will hit the upper control arm. You can try to buy rims with 7 3/8'' back spacing or make up that difference with a wheel spacer. When moving the wheel out enough for the tire to clear the control arm, it is going to make the tire sit flush with the top lip of the fender. This means that the tire is no longer sitting inside the fender but under it. When lowered, that leaves maybe an inch of clearance between the tire and the fender. Passengers, bumps, cornering????? I did it, I know.
