        What size(s) are you running in the 17's?

        Generally can't go wrong with 18x9.5" fronts, and 18x9.5" to 18x10.5" in the back. Offset for 18x9.5 should be in the range of 45-57mm. For the back:

        18x9.5": 45-57mm
        18x10.0": 45-55mm
        18x10.5": 47-52mm

        Tire choices would be 275/35-18 (25.5") or 285/35-18 (25.9") for the 9.5" or 10.0" wheels. You could push it to a 295/35-18 (26.2") on the 10.5" wheel.
