When I downsized my Ram 1500 pickup from 17" to 16" wheels to get a little more user-friendly cruising speed, I discovered that the smaller diameter wheels would drag on the calipers, front and rear . I ended up installing longer lug bolts in the hubs and adding spacers between the hub and the wheel mounting surfaces to move the wheels out 3/4" in the rear and 1/2" in the front. The shorter profile tires moved the 2K RPM cruise speed "sweet spot" in overdrive down from 75+ MPH to 65. No more "speeding ticket magnet"!
