Will 1998 dodge ram 15 inch rims fit a 1997 Jeep cj?

No, 1998 Dodge Ram 15-inch rims will not fit a 1997 Jeep CJ without modifications. The bolt pattern, offset, and hub diameter of the two vehicles differ, which means the rims won't align properly with the Jeep's wheel hubs. It's best to consult specifications or seek aftermarket wheels designed specifically for the Jeep CJ.
