They should work for you Charlie. Same bolt pattern. The only difference is the whole in the center of the wheels. Larger on the frontier for the hubs and smaller on the Titans since there are no hubs. My dad bought some 18" titan rims, but they would not work on his 00 fronty due to the center whole size.
