Welcome! Your '97 is a TJ just so you know. The bolt pattern on stock TJ wheels is 5x4.5. I ran tires that size back in '97 with 3.75" backspace on a 8.5" wide wheel and had no problems. If you want to use the wheels you have, placing a washer or possibly two under the steering stop studs should clear up your frame rub on full turn steering.
I'm not familiar with the wheels you mention, but the same backspace issues apply. BTW - 15" tires are almost always less expensive than comparable larger sized tires if that matters to you.
